Mastering Docker: A Complete Guide for Beginners

Docker has revolutionized the way developers build, package, and deploy applications. It simplifies software deployment by allowing applications to run in isolated environments called containers. This Docker tutorial will provide beginners with a complete understanding of Docker, how it works, and how to use it effectively.

What is Docker?

Docker is an open-source platform designed to automate the deployment of applications inside lightweight, portable containers. It ensures that applications run consistently across different computing environments.

Key Features of Docker:

Portability: Containers work across different platforms without modification.

Efficiency: Containers share the host OS kernel, reducing resource consumption.

Scalability: Easy to scale applications up or down based on demand.

Isolation: Each container runs in its own isolated environment.

Why Use Docker?

Before Docker, applications were often deployed using virtual machines (VMs), which were resource-intensive. Docker provides a more lightweight and efficient alternative by using containerization.

Benefits of Docker:

Faster Deployment: Containers launch within seconds.

Consistency: Works the same on different systems, eliminating “it works on my machine” issues.

Better Resource Utilization: Uses fewer resources than traditional VMs.

Simplified Dependency Management: All dependencies are packaged within the container.

Installing Docker

To start using Docker, you need to install it on your system. Follow these steps based on your OS:

Windows & macOS:

Download Docker Desktop from Docker’s official website.

Install Docker and restart your system.

Verify installation by running:

docker --version

Linux:

Update the package database:

sudo apt update

Install Docker:

sudo apt install docker.io -y

Start the Docker service:

sudo systemctl start docker

sudo systemctl enable docker

Verify installation:

docker --version

Understanding Docker Components

Docker consists of several core components that help in container management.

1. Docker Engine

The runtime that builds and runs containers.

2. Docker Images

A Docker Image is a blueprint for creating containers. It contains the application code, dependencies, and configurations.

3. Docker Containers

A Docker Container is a running instance of an image. It runs in an isolated environment.

4. Docker Hub

A cloud-based registry where Docker images are stored and shared.

Basic Docker Commands

Here are some essential Docker commands to help you get started:

1. Check Docker Version

docker --version

2. Pull an Image from Docker Hub

docker pull ubuntu

3. List Available Images

docker images

4. Run a Container

docker run -it ubuntu bash

This command runs an Ubuntu container and opens an interactive shell.

5. List Running Containers

docker ps

6. Stop a Running Container

docker stop <container_id>

7. Remove a Container

docker rm <container_id>

8. Remove an Image

docker rmi ubuntu

Creating a Docker Container from a Custom Image

To create a custom container, follow these steps:

1. Create a Dockerfile

A Dockerfile is a script containing instructions to build an image.

Create a Dockerfile with the following content:

# Use an official Python runtime as a parent image

FROM python:3.9

# Set the working directory

WORKDIR /app

# Copy the current directory contents into the container at /app

COPY . /app

# Install any dependencies

RUN pip install --no-cache-dir -r requirements.txt

# Run the application

CMD ["python", "app.py"]

2. Build the Docker Image

Run the following command:

docker build -t my-python-app .

3. Run a Container from the Image

docker run -p 5000:5000 my-python-app

Managing Data with Docker Volumes

Docker volumes are used for persistent storage. To create and use a volume:

Create a volume:

docker volume create my_volume

Attach it to a container:

docker run -v my_volume:/app/data ubuntu

Check available volumes:

docker volume ls

Docker Compose: Managing Multi-Container Applications

Docker Compose is a tool used to define and manage multi-container applications.

Example docker-compose.yml:

version: '3'

services:

  web:

    image: nginx

    ports:

      - "8080:80"

  db:

    image: mysql

    environment:

      MYSQL_ROOT_PASSWORD: password

To start the services, run:

docker-compose up

Best Practices for Using Docker

Use Official Images: Minimize security risks by using verified images from Docker Hub.

Minimize Image Size: Use lightweight base images like alpine.

Keep Containers Stateless: Store persistent data in volumes.

Remove Unused Containers and Images: Clean up using:

docker system prune -a

Limit Container Resources: Use flags like --memory and --cpu-shares to allocate resources efficiently.

Conclusion

Docker is an essential tool for modern software development, enabling efficient and scalable application deployment. This Docker tutorial For beginner covered the basics, from installation to container management and best practices. Whether you are new to containerization or looking to refine your skills, mastering Docker will significantly improve your workflow.

Start experimenting with Docker today and take your development process to the next level!

The Remote - Containers extension lets you use a Docker container as a full-featured development environment. Whether you deploy to containers or not, containers make a great development environment because you can:

Develop with a consistent, easily reproducible toolchain on the same operating system you deploy to.

Quickly swap between different, isolated development environments and safely make updates without worrying about impacting your local machine.

Make it easy for new team members / contributors to get up and running in a consistent development environment.

Try out new technologies or clone a copy of a code base without impacting your local setup.

Rhel Docker

Rhel Docker Ce

The extension starts (or attaches to) a development container running a well defined tool and runtime stack. Workspace files can be mounted into the container from the local file system, or copied or cloned into it once the container is running. Extensions are installed and run inside the container where they have full access to the tools, platform, and file system.

Rhel Docker

Amazon Web Services (AWS) and Red Hat provide a complete, enterprise-class computing environment. Red Hat solutions on AWS give customers the ability to run enterprise traditional on-premises applications, such as SAP, Oracle databases, and custom applications in the cloud.

Windows 10 Home (2004+) requires Docker Desktop 2.2+ and the WSL2 back-end. (Docker Toolbox is not supported.) macOS: Docker Desktop 2.0+. Linux: Docker CE/EE 18.06+ and Docker Compose 1.21+. (The Ubuntu snap package is not supported.) Containers: x8664 / ARMv7l (AArch32) / ARMv8l (AArch64) Debian 9+, Ubuntu 16.04+, CentOS / RHEL 7+ x8664.

Docker volumes allow you to back up, restore, and migrate data easily. This tutorial explains what a Docker volume is and how to use it, as well as how to mount a volume in Docker.

You then work with VS Code as if everything were running locally on your machine, except now they are isolated inside a container.

System Requirements

Local:

Windows:Docker Desktop 2.0+ on Windows 10 Pro/Enterprise. Windows 10 Home (2004+) requires Docker Desktop 2.2+ and the WSL2 back-end. (Docker Toolbox is not supported.)

macOS: Docker Desktop 2.0+.

Linux: Docker CE/EE 18.06+ and Docker Compose 1.21+. (The Ubuntu snap package is not supported.)

Containers:

x86_64 / ARMv7l (AArch32) / ARMv8l (AArch64) Debian 9+, Ubuntu 16.04+, CentOS / RHEL 7+

x86_64 Alpine Linux 3.9+

Other glibc based Linux containers may work if they have needed prerequisites.

While ARMv7l (AArch32), ARMv8l (AArch64), and musl based Alpine Linux support is available, some extensions installed on these devices may not work due to the use of glibc or x86 compiled native code in the extension. See the Remote Development with Linux article for details.

Note that while the Docker CLI is required, the Docker daemon/service does not need to be running locally if you are using a remote Docker host.

Installation

To get started, follow these steps:

Install VS Code or VS Code Insiders and this extension.

Install and configure Docker for your operating system.

Windows / macOS:

Install Docker Desktop for Mac/Windows.

Working with Git? Here are two tips to consider:

If you are working with the same repository folder in a container and Windows, be sure to set up consistent line endings. See tips and tricks to learn how.

If you clone using a Git credential manager, your container should already have access to your credentials! If you use SSH keys, you can also opt-in to sharing them. See Sharing Git credentials with your container for details.

Getting started

Follow the step-by-step tutorial or if you are comfortable with Docker, follow these four steps:

Follow the installation steps above.

Clone https://github.com/Microsoft/vscode-remote-try-node locally.

Start VS Code

Run the Remote-Containers: Open Folder in Container... command and select the local folder.

Check out the repository README for things to try. Next, learn how you can:

Use a container as your full-time environment - Open an existing folder in a container for use as your full-time development environment in few easy steps. Works with both container and non-container deployed projects.

My Homelab/Office 2020 - DFW Quarantine Edition

Moved into our first home almost a year ago (October 2019), I picked out a room that had 2 closets for my media/game/office area. Since the room isn't massive, I decided to build a desk into closet #1 to save on space. Here 1 of 2 shelves was ripped off, the back area was repainted gray. A piece of card board was hung to represent my 49 inch monitor and this setup also gave an idea how high I needed the desk. 

On my top shelf this was the initial drop for all my Cat6 cabling in the house, I did 5 more runs after this (WAN is dropped here as well).

I measured the closet and then went to Home Depot to grab a countertop. Based on the dimensions, it needed to be cut into an object shape you would see on Tetris. 

Getting to work, cutting the countertop.

My father-in-law helped me cut it to size in the driveway and then we framed the closet, added in kitchen cabinets to the bottom (used for storage and to hide a UPS). We ran electrical sockets inside the closet. I bought and painted 2 kitchen cabinets which I use for storage under my desk as well.

The holes allowed me to run cables under my desk much easier, I learned many of these techniques on Battlestations subreddit and Setup Wars on Youtube. My daughter was a good helper when it came to finding studs.

Some of my cousins are networking engineers, they advised me to go with Unifi devices. Here I mounted my Unifi 16 port switch, my Unifi Security Gateway (I'll try out pfSense sometime down the line), and my HD Homerun (big antenna is in the attic). I have Cat6 drops in each room in the house, so everything runs here. On my USG, I have both a LAN #2 and a LAN #1 line running to the 2nd closet in this room (server room). This shot is before the cable management. 

Cable management completed in closet #1. Added an access point and connected 3 old Raspberry Pi devices I had laying around (1 for PiHole - Adblocker, 1 for Unbound - Recursive DNS server, and 1 for Privoxy - Non Caching web proxy). 

Rats nest of wires under my desk. I mounted an amplifier, optical DVD ROM drive, a USB hub that takes input from up to 4 computers (allows me to switch between servers in closet #2 with my USB mic, camera, keyboard, headset always functioning), and a small pull out drawer. 

Cable management complete, night shot with with Nanoleaf wall lights. Unifi controller is mounted under the bookshelf, allows me to keep tabs on the network. I have a tablet on each side of the door frame (apps run on there that monitor my self hosted web services). I drilled a 3 inch hole on my desk to fit a grommet wireless phone charger. All my smart lights are either running on a schedule or turn on/off via an Alexa command. All of our smart devices across the house and outside, run on its on VLAN for segmentation purposes. 

Quick shot with desk light off. I'm thinking in the future of doing a build that will mount to the wall (where "game over" is shown). 

Wooting One keyboard with custom keycaps and Swiftpoint Z mouse, plus Stream Deck (I'm going to make a gaming comeback one day!). 

Good wallpapers are hard to find with this resolution so pieced together my own. 

Speakers and books at inside corner of desk. 

Speakers and books at inside corner of desk. 

Closet #2, first look (this is in the same room but off to the other side). Ran a few CAT6 cables from closet #1, into the attic and dropped here (one on LAN #1, the other on LAN #2 for USG). Had to add electrical sockets as well. 

I have owned a ton of Thinkpads since my IBM days, I figured I could test hooking them all up and having them all specialize in different functions (yes, I have a Proxmox box but it's a decommissioned HP Microserver on the top shelf which is getting repurposed with TrueNAS_core). If you're wondering what OSes run on these laptops: Windows 10, Ubuntu, CentOS, AntiX. All of these units are hardwired into my managed Netgear 10gigabit switch (only my servers on the floor have 10 gigabit NICs useful to pass data between the two). Power strip is also mounted on the right side, next to another tablet used for monitoring. These laptop screens are usually turned off.

Computing inventory in image:

Lenovo Yoga Y500, Lenovo Thinkpad T420, Lenovo Thinkpad T430s, Lenovo Thinkpad Yoga 12, Lenovo Thinkpad Yoga 14, Lenovo Thinkpad W541 (used to self host my webservices), Lenovo S10-3T, and HP Microserver N54L 

Left side of closet #2 

**moved these Pis and unmanaged switch to outside part of closet** 

Since I have a bunch of Raspberry Pi 3s, I decided recently to get started with Kubernetes clusters (my time is limited but hoping to have everything going by the holidays 2020) via Rancher, headless. The next image will show the rest of the Pis but in total:

9x Raspberry Pi 3  and 2x Raspberry Pi 4 

2nd shot with cable management. The idea is to get K3s going, there's Blinkt installed on each Pi, lights will indicate how many pods per node. The Pis are hardwired into a switch which is on LAN #2 (USG). I might also try out Docker Swarm simultaneously on my x86/x64 laptops. Here's my compose generic template (have to re-do the configs at a later data) but gives you an idea of the type of web services I am looking to run: https://gist.github.com/antoinesylvia/3af241cbfa1179ed7806d2cc1c67bd31

20 percent of my web services today run on Docker, the other 80 percent are native installs on Linux and or Windows. Looking to get that up to 90 percent by the summer of 2021.

Basic flow to call web services:

User <--> my.domain (Cloudflare 1st level) <--> (NGINX on-prem, using Auth_Request module with 2FA to unlock backend services) <--> App <-->  DB.

If you ever need ideas for what apps to self-host: https://github.com/awesome-selfhosted/awesome-selfhosted 

Homelabs get hot, so I had the HVAC folks to come out and install an exhaust in the ceiling and dampers in the attic. 

I built my servers in the garage this past winter/spring, a little each night when my daughter allowed me to. The SLI build is actually for Parsec (think of it as a self hosted Stadia but authentication servers are still controlled by a 3rd party), I had the GPUs for years and never really used them until now.

Completed image of my 2 recent builds and old build from 2011.

Retroplex (left machine) - Intel 6850 i7 (6 core, 12 thread), GTX 1080, and 96GB DDR4 RAM. Powers the gaming experience.

Metroplex (middle machine) - AMD Threadripper 1950x (16 core, 32 thread), p2000 GPU, 128GB DDR4 RAM.

HQ 2011 (right machine) - AMD Bulldozer 8150 (8 cores), generic GPU (just so it can boot), 32GB DDR3 RAM. 

I've been working and labbing so much, I haven't even connected my projector or installed a TV since moving in here 11 months ago. I'm also looking to get some VR going, headset and sensors are connected to my gaming server in closet #2. Anyhow, you see all my PS4 and retro consoles I had growing up such as Atari 2600, NES, Sega Genesis/32X, PS1, Dreamcast, PS2, PS3 and Game Gear. The joysticks are for emulation projects, I use a Front End called AttractMode and script out my own themes (building out a digital history gaming museum).

My longest CAT6 drop, from closet #1 to the opposite side of the room. Had to get in a very tight space in my attic to make this happen, I'm 6'8" for context. This allows me to connect this cord to my Unifi Flex Mini, so I can hardware my consoles (PS4, PS5 soon)

Homelab area includes a space for my daughter. She loves pressing power buttons on my servers on the floor, so I had to install decoy buttons and move the real buttons to the backside. 

Next project, a bartop with a Raspberry Pi (Retropie project) which will be housed in an iCade shell, swapping out all the buttons. Always have tech projects going on. Small steps each day with limited time.

Linuxizing the Office: An Interview with The Mad Botter

If you follow us on Twitter, you’ve probably seen software development company The Mad Botter dangling a System76 machine before your very eyes. Thanks to the company’s recent conversion to Linux, that’s not the only System76 machine you’ll find there! This week, we sat down with Michael Dominick, The Mad Botter’s Founder and CEO, to discuss his team’s switch to System76.

What kind of work goes on at The Mad Botter?

Michael: We’re a software development company. We mostly code on Python, along with some Ruby and Rust, coding IDEs, and using a whole lot of LibreOffice. One of our products is a radar display that runs on Linux and Windows. We actually use a Thelio as a flight simulator to test our software.

Our new product is an automation tool called Rabbot. It involves us having to very quickly spin up a bunch of Ubuntu servers for customers who need them. Having the .deb instances on our computers has made that process a hundred times easier, because we can deploy test units to our machines with the same docker container that works exactly the same as it does on our cloud instances.

Why is it called Rabbot? And what’s with The Mad Botter?

I went a little crazy with the Lewis Carroll references. I have a degree in literature, so I’m very familiar with Carroll’s work. When I moved from New Jersey down to Florida, the name of the company conflicted with a very large football team in Florida, and they did not like that. I had to rejigger everything. We already had a product called Alice at the time, so we decided to build around that.

How long have you been in business?

The Mad Botter has been around for 3 years, and the company before it in New Jersey was around for an additional 3 years. I’ve been running development businesses for around 11 years.

How did you hear about System76?

When I was hosting Coder Radio with Chris Fisher, he would always tease me for being an Apple guy. You know—hipster coffee, the whole thing. He told me, “If you really want a controlled experience to try Linux, take a look at these guys in Denver.” So I did. It wasn’t a huge investment to try on a laptop, and I ended up loving it, so I got the Ratel tower. That was the beginning of a long road to Linux purity.

What System76 machines do you have around the office?

I was the first one to adopt a System76 computer at the company. Now, to make life easy, we only buy System76 computers. Currently we have an older Galago Pro, a Thelio, and 3 Lemur Pros. There’s a couple of Darter Pros running around, too. All of our machines are running Pop!_OS 20.04.

Moving forward, we’re standardizing down to the Lemur Pro and the Oryx Pro. People who have to run VMs are getting the Oryx Pro because you can spec it up a little more. Everybody else is using the Lemur Pro, which is a great all-around computer. The Thelio is a special case because we have to run our flight simulation software on it.

What prompted you to bring your company fully onto Linux?

Honestly, it was macOS Catalina. We were having too many problems with people updating OS X and breaking Homebrew packages, to the point where we had to reinstall our custom toolchain every time we updated. The last guy on Mac updated to Catalina recently, and he had to struggle with Excel libraries because Apple moves things between OS versions. It just wasn’t worth it. I’ve been talking about it for about a year with my CTO.

All of our back-end service runs Ubuntu. Most of the client-side work we’re doing is for IOT devices, and that’s all Linux. We ended up basically having an expensive machine so that we could emulate Linux on anything. It didn’t make a lot of sense to keep using Mac, so we switched.

How was the transition from macOS to Linux?

Actually super easy! Once we wrote a few setup scripts and packages we needed for different jobs in our pipeline, we were up and running. We already had a bunch of scripting and automations for the servers we had, and they’re all on Ubuntu, so it’s not a big jump in terms of the command line.

How did you find the overall experience on Pop!_OS 20.04?

I found it pretty intuitive. Learning the keyboard shortcuts took about a week. I really don’t have any issues. I like the tiling, I use that every day. It definitely makes it easier to multitask on a laptop screen.

Have you tried other distros?

We had a brief stint with Fedora, but because all of our back end was on Debian or Ubuntu, it made sense to stick with that Debian world. We also tried Linux Mint briefly. But honestly the ease of being able to buy a system pre-installed with Pop!_OS that you guys support—where I can just go to your GitHub and see if there’s an issue—is an attractive option.

Have you had any experiences with our support team?

I have a bad habit of spilling tea and other beverages in my laptops... A few times you guys were able to walk me through my issue. I think the most recent one was with Thelio. There was an issue with the graphics card where only one of the DisplayPorts actually worked, so they walked me through trying different things and we were eventually able to figure out why that was happening.

Panoptes, an open source distributed network telemetry ecosystem is now available on Docker

James Diss, Software Systems Engineer, Verizon Media

Panoptes is an open source network telemetry system that we built to replace a myriad of tools and scripts built up over time to monitor the fleet of hosts worldwide.

The core framework is designed to be extended through the use of plugins which allows the many different devices and device types to be monitored. Within Verizon Media, Panoptes provides the data collection layer that we feed to other projects to allow for visualization of device health according to need, alerting and collation of information.

Normally the components of Panoptes run as a distributed system that allows for horizontal scaling and sharding to different geographical and virtual locations, handling thousands of endpoints, but this can be a difficult environment to simulate. Therefore, we have created a docker image which holds the entire structure of Panoptes in a single container.

I hasten to add that this is not a production instance of Panoptes, and we would not recommend trying to use the docker container “as-is”. Rather, it is more of a workbench installation to examine in motion.

The container is entirely self-contained and builds Panoptes using the freely available package with pip install yahoo-panoptes; it is open-source and built on the ubiquitous Ubuntu 18.04 (Bionic Beaver). A set of scripts are supplied that allow for examination of the running container, and it also runs a Grafana instance on the container to see the data being collected. A dashboard already exists and is connected to the internal data store (influxdb) collecting the metrics.

If you would like to get started right away, you can have Panoptes running very easily by using the prebuilt docker hub image;

docker pull panoptes/panoptes_docker docker run -d \ --sysctl net.core.somaxconn=511 \ --name="panoptes_docker" \ --shm-size=2G \ -p 127.0.0.1:8080:3000/tcp \ panoptes/panoptes_docker

This pulls the docker image from docker hub, then runs the image with a couple of parameters. In order, the “sysctl” command allows redis to run, the “name” is the name that the running container will be given (docker ps shows the currently running containers), and the “shm-size” reserves memory for the container. The “p” parameter exposes port 3000 inside the container to port 8080 on the outside; this is to allow the Grafana library to communicate outside of the container.

If you’re more interested in building the image yourself (which would allow you to play with the configuration files that are dropped in place during the build), clone the repo and build from source.

git clone https://github.com/yahoo/panoptes_docker.git && cd panoptes_docker docker build . -t panoptes_docker

Once the image is built, run with:

docker run -d \ --sysctl net.core.somaxconn=511 \ --name="panoptes_docker" \ --shm-size=2G \ -p 127.0.0.1:8080:3000/tcp \ panoptes_docker

Parity Wallet

The Parity Wallet is one of several well-liked remedies that were designed for you to serve as each a wallet and a software between the Ethereum software and your laptop or computer. Like MyEtherWallet, Parity is genuinely a browser and not some sort of budget. Parity even bills itself as an �Ethereum Browser� � a web browser is needed because Ethereum is really an extensive system. The idea guiding Parity is to provide the particular most effective connection between Ethereum and various technologies possible. Ethereum came to be as a decentralized data safe-keeping solution, but it is widespread since cryptocurrency because it will be encrypted and very safe. The great way to think of Ethereum is a new second, encrypted network in the internet. Parity is created like a entrance to that network together with an software between the web and even Ethereum. A FULL NODE WALLET Parity was designed since a full-node pocket book the fact that means you can carry out everything this. You will store Ethereum and ERC-20 up to date initial cryptocurrency solutions (ICOs). More importantly, you are able to send and receive bills, buy and sell Azure and ICO tokens, mine, invest in Ethereum plus add the wallet with a wide variety of programs. That makes Parity Ethereum management tool you can add to a number regarding internet browsers and run upon a number of operating systems. Presently, it works with Ubuntu, OS 10, Dockers and Home windows. One reason why users like the Parity Wallet is definitely that provides a dashboard that can be used to manage Ether on your own screen. It will perhaps purpose on desktops just where MyEtherWallet and Mist have got been extra. EASY TO BE ABLE TO USE Parity is pretty effortless if you abide by the instructions in the dash, which are fairly straightforward together with explanatory. If anyone look carefully you ought to see everything explained in order to anyone. This makes saving and managing Ethereum since easy as shopping with Amazon. Although it might take a good while to get your money to exhibit way up in Parity, users survey that it takes many time to be able to record dealings. Another favorite feature is the easy recovery bed sheet with a quick study (QR) code that an individual can scan with nearly any phone. That permits you regain your Parity account quick if that is lost or your own personal pc crashes. LOTS INVOLVING SUPPORT Several developers and even consumers like Parity mainly because the idea has a lot of assist. It is quite uncomplicated to contact and assist the firm responsible intended for the finances. The browser was the creation of the company named Parity Solutions.

That also contains some associated with the most experienced cryptocurrency technical engineers around. HIGH AMOUNT OF KNOWLEDGE Parity Systems includes some of the people that helped develop Ethereum itself. Parity�s founder Doctor Gavin Solid wood, worked well together with Ethereum founder Vitalik Buterin when this individual first designed the blockchain system. Wood is actually wanting to develop a greater and much more comprehensive Ethereum software built to serve as the full-service payment network. Often the Parity Wallet is meant to become the cornerstone of that system. Ethereum Parity v2.3.4 can be to create next-generation Fin-Tech solutions which can be marketed for you to banks, retailers, off-set money, credit card companies, governing bodies, and other organizations. These remedies would certainly utilize the Ethereum blockchain to make market segments, retail systems, and economic products. THE FEATURES CONNECTED WITH PARITY Some Parity�s illustrates and selling things incorporate: Will work with The apple company McIntosh computers via the OSX operating technique. Will certainly work using the Linux-based Ubuntu operating system. Works together with an ecommerce applications software called Docker.

Notes for myself: Configuring your development environment with Docker and Java/Spring

This is a note to the future: setting up a development environment

Docker

This may be the first software to install and set up the everything goes smoothly while I prepare the environment for this new project.

Here, the docker documentation is your best friend. I know, the direct link is on Ubuntu because I use this respective OS.

Notes to myself:

Install the Docker Engine using the repository

Then do the install for Docker Desktop for Linux

I encounter myself with some errors that only a clean install again-and-again fixes. So, I took this as advice for the future.

Also, don’t forget to set the permissions.

This 4.2 is really important if can’t connect to the docker daemon.

Java/Spring

Always verify the source compatibility from the project and check the IDE’s SDK to build for gradle or maven depending on the project.

And this is enough to everything doesn't take no more than 30 minutes, instead of the hours of documentation and search it through that it took me to fix a bunch of errors.

Now, you see the main screen of Kitematic. The first time you start Kitematic, it will create a new virtual machine in VirtualBox. Using Kitematic 5.1 Virtual Machine for Docker Machine With this IP address and port, container can be accessed from the outside world.ĥ. Be aware that all your containers created on Docker machine have this same IP address. When Docker Terminal is started, you will see there is an IP address, eg. For example, you cannot access docker in host terminal if it’s in the virtual machine. Whenever you start to work in command lines, be sure you are in the right terminal. In Docker Terminal, execute ‘docker exec -it sh’ Spotlight Search->Docker QuickStart Terminal There are three types of terminal if docker is hosted on virtual machine. In this case, you can only use Docker QuickStart Terminal to access docker. There is one more VirtualBox VM between host machine and docker machine.

If you install docker through Docker Toolbox, like what we did in this posting, the structure is different. The host terminal can access both docker and host system. If you install docker manually, like what I did for Ubuntu mentioned in the posting Installing and Using Docker on Ubuntu, the docker is hosted directly by host machine. It’s necessary to understand the structure of docker and what terminal can access it. You don’t need to install Kitematic separately, it is installed as you install Docker Toolbox.Īfter the installation is finished.If you’ve already installed Oracle VirtualBox on your Mac, then this component won’t be installed.Download and follow the wizard to install. You can find its source files repository on GitHub. Kitematic integrates with Docker Machine to provision a VirtualBox VM and install the Docker Engine locally on your machine. Kitematic automates the Docker installation and setup process and provides an intuitive graphical user interface (GUI) for running Docker containers. Kitematic is an open source project built to simplify and streamline using Docker on a Mac or Windows PC. a shell preconfigured for a Docker command-line environment.Docker Compose for running the docker-compose commands.Docker Engine for running the docker commands.Docker Machine for running docker-machine commands.The Docker Toolbox is an installer to quickly and easily install and setup a Docker environment on your computer. Use Kitematic to easily manage docker containers without using Docker command-line.

See this StackOverflow question for Google Cloud Functions. You’ll need to extract the distribution-specific package, bundle it with necessary libraries, configuration and/or fonts and then upload it. Head over to the packaging repository and start a discussion if your platform isn’t listed.

Install weka ubuntu 16.04 install#

cannot install package – you can always extract it (google for extract from ), but you’ll need to have the dependencies installed.

the major release isn’t listed – we only support LTS versions, so try a LTS version older than your release.

Install weka ubuntu 16.04 Patch#

but not the specific patch release – try it, as it’s very likely to work regardless.If the distribution you are using is listed:

Install weka ubuntu 16.04 download#

I don’t see an appropriate download for my platform! It’s not possible to abstract everything out and test/fix everything for every OS/distribution with the limited resources this project has – it makes more sense to make distribution-specific versions which are almost guaranteed to work, as they use the specific versions that the distribution has packaged. This may work for them, but wkhtmltopdf also depends on the runtime configuration on actual fonts installed (i.e. alpine is not recommended with binary wheels if you google for it), and requires you to statically link everything. While Python has also tried to do this using manylinux – it doesn’t always work well (e.g. So the generic binaries never really worked on Alpine. This doesn’t use glibc at all, but the musl libc. But due to the rise of Docker, the alpine image became very popular. This was worked around earlier by using CentOS 6 (which had an old enough glibc version). If you compile with a later version, it won’t work on a distribution which uses an older version.

incompatible libc: not every distribution has the same glibc version.

This was the direct motivation to create a separate packaging repository. This led to a situation where there was effectively zero backward compatibility and things started breaking randomly – see #3001 for a very long read of the problems faced.

different OpenSSL versions: due to OpenSSL having a bad track record then ( it’s better now), distributions started aggressively upgrading their OpenSSL version and disabling unused parts of the library.

While this could be addressed easily by linking them statically (and was actually done so for previous releases) – it broke down when it came to the next point.

Install weka ubuntu 16.04 series#

This was especially the case for libpng and libjpeg, with a lot of distributions choosing between the 1.2, 1.5 and 1.6 series for the former and multiple versions of libjpeg and/or its fork libjpeg-turbo.

different library versions: not every distribution provides the same versions.

Install weka ubuntu 16.04 trial#

Over a period of time, major areas of divergence between distributions were found by trial and error: A static build means that only Qt is linked in this manner – the remaining system packages still need to be installed. Why are there no “generic” Linux builds ( which were provided earlier)?Īlthough the builds are static, it is very important to understand what it means in the context of Qt – on which wkhtmltopdf is built. This leads to quite different behavior – you get a later web engine, but behavior can vary from distribution to distribution. Most Linux distributions ( quite understandably) would prefer that this project upstreamed the patches, and choose to compile without those features. Some features require you to use a patched Qt, because those aren’t yet upstream – please read the project status for a longer explanation. FAQ Why do you have static builds with patched Qt? If you need versions older than 0.12.0, you can look at the obsolete downloads. It is recommended to use the latest stable release instead, and report an issue if there is a regression from a previous release. Please note that bug reports will not be accepted against the following, which are considered obsolete. OS/DistributionĪll of the above packages were produced automatically via Azure Pipelines and were built on the latest OS/distribution patch release at the time of the release. The current stable series is 0.12.6, which was released on J– see changes since 0.12.5. All downloads are currently hosted via GitHub releases, so you can browse for a specific download or use the links below.ĭo not use wkhtmltopdf with any untrusted HTML – be sure to sanitize any user-supplied HTML/JS, otherwise it can lead to complete takeover of the server it is running on!
