How to host local Club Penguin Private Server (CPPS) on Silicon Mac (M1/M2/M3) thru play.localserver & Solero's Wand install.

I spent so long looking for a solution to this that I want to contribute what worked for me. I got so frustrated looking for something that worked, and I hope this guide will help others avoid that frustration.

This is NOT a guide on hosting or serving a CPPS. This is a guide on making a CPPS playable by locally hosting your server on your Silicon M1/M2/M3 Macbook. This worked on my M3 Macbook, and, in my experience, it seems the newer the hardware/operating system gets, the harder it is accomplish this.

DISCLAIMER *I do not know very much about this topic. I can paste commands into terminal and execute them, I know how to install DMG files I downloaded from the internet (the bar is in hell, I am aware), and I know how to enter play.localhost to run this in a browser. I am no expert; this guide is for beginners like myself who want a CPPS. This is beginner-level stuff. If you want advice or need help hosting, refer to the Wand Github page, Solero's Dash (an actual web-hosting solution for Houdini/Wand), Solero's discord, or, when in doubt, Google it. (I recommend only asking for help in Solero's discord for help AFTER trying your best to search for a solution, and even after that, trying to search key terms in their chat logs. They often have to repeat the same advice over, and over, and over again.)*

TLDR; IDK shit about shit

USING WAND INSTALLER

wand description from github: Wand makes it easy to configure dash, houdini and a media server utilizing docker & docker-compose.

All the assets are located here.

Installation instructions from the above link:

Installation script 1. run the script: bash <(curl -s https://raw.githubusercontent.com/solero/wand/master/install.sh) 2. Answer Questions which are: Database password (Leave blank for random password) Hostname (example: clubpenguin.com) (Leave empty for localhost) External IP Address (Leave empty for localhost) 3. Run and enjoy. Run this command: $ cd wand && sudo docker-compose up

The steps I took:

1. Install Docker via Terminal & Homebrew.

Installing the Docker DMG file did not work properly when I tried. I realized later that Docker is seperate from Docker Desktop (the DMG file). I got Docker to work by using Terminal to install Homebrew, and then using Homebrew to install Docker.

Indented text = paste into Terminal.

Command to install Homebrew:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Ensure Homebrew is installed:

brew --version

Install Docker:

brew install docker

Recommended: Install Docker Desktop (useful in determining if your server is running, stopped, or stuck in a restart loop).

brew install --cask docker

Run Docker Desktop:

open -a Docker

2. Run installation script:

bash <(curl -s https://raw.githubusercontent.com/solero/wand/master/install.sh)

From Github instructions:

Answer Questions which are:

Database password (Leave blank for random password)

Hostname (example: clubpenguin.com) (Leave empty for localhost)

External IP Address (Leave empty for localhost)

3. $ cd wand && sudo docker-compose up

This is what is provided in the Github. This command didn't work on Mac; I believe it's formatted for Linux OS. Here's how I broke it up and enabled it to run from Mac's Terminal.

Navigate to Wand directory:

cd wand

Double-check if you're in the right directory:

ls

Start Docker container:

docker-compose up

If the above doesn't work, try

docker compose up

or

brew install docker-compose

Takes a second...

Ensure Docker is running:

docker info

If it isn't, open the Docker Desktop application.

*After using compose up, this error may appear:*

WARN[0000] /Users/[user]/wand/docker-compose.yml: the attribute version is obsolete, it will be ignored, please remove it to avoid potential confusion

This is harmless. If you get annoyed by errors, this can be solved by:

nano docker-compose.yml

See Version 3.7 at the top? Delete that line.

Ctrl-X (NOT COMMAND-X) to exit, Y to save, Enter.

PLAY.LOCALHOST

Type http://PLAY.LOCALHOST into a browser.

Create a penguin.

Try logging in that penguin:

This step was agony. I'm not savvy with running obsolete or deprecated software, and, of course, Club Penguin (and Houdini/Wand's assest) uses Flash, which was discontinued, and timebombed by Adobe, in 2021.

I tried Ruffle. Club Penguin Journey uses Ruffle, so why can't I?

Running Ruffle in Firefox:

No luck.

In the Solero discord, they'll direct to this blog post:

This method does not work on Mac M1/M2/M3. The program is "out of date" and you cannot run it. It works on Macbook's running Sonoma and backward. I'm on an M3 running Sequoia.

they'll often post this video in the discord:

In theory, this method should work, and it does for many, but for whatever reason, not on my M3. I tried different versions of Ungoogled, I tried so many different patches of Pepperflash, and it never cooperated. I tried Pepperflash, I tried Fast Patch!, I tried dedicated Flash browsers, running Flash plugins for Pale Moon, Ungoogled, Waterfox, but I could never get past him.

Every time I see this stupid penguin's face I'm filled with rage. But I am going to save you that rage!!!

If you get this method to work, yay! I could not. Maybe I don't know enough about patching, maybe I'm a little tech stupid.

WHAT WORKED: Using a dedicated CPPS desktop application that allows you to plug in a URL.

I give you...

He is your solution, your answer to

I discovered this solution through Solero's Discord, when someone answered a question re: playing online.

Waddle Forever was not what I was looking forever, but I noticed in their credits:

The electron client is originally forked from the Club Penguin Avalanche client. The server is based in solero's works in reverse engineering the Club Penguin server (Houdini server emulator). The media server is also mostly from solero's media servers.

And that's how I found out the solution: Using CPA Client

Download the CPAvalanche Client

It runs Adode Flash x64. Easy peasy.

(the instructions are in Portuguese, but for English users:

Navigate to releases.

And download this one:

Once downloaded, open.

Drag into applications.

Run http://play.localhost through the client:

Open CPAvalanche Client. It will direct you to CPAvalance once loaded, but you're here because you want to play play.localhost.

Navigate to CPAvalanche Client next to your Apple. Click Mudar a URL do Club Penguin.

Press Sim.

URL: http://play.localhost

Ok.

Press Login once the page loads, and...

That's it! No more penguin! Have fun :)

Progress so far of mobile server (dev log)

So I was successful in turning my old phone into apache web server. The phone had some hardware issue that it always clicked on the screen randomly so I had to maneuverer my way installing Linux and apache into the phone. I had to set up proxies as well to connect to it with the open internet. So far it is working well. Sometimes I have to reroute the connections since it is running over mobile data? I am thinking of getting a dynamic DNS. But I have never tried dynamic DNS before so I am not ready to explore that yet. Plus, I don't know if I would get a static IP from it or a straight away domain name? I mean both are okay, but both have pros and cons of the usage.

Like if I get a static IP , I can run virtual hosts in apache and run multiple websites pointing A record of the domain to the same website.

And lets say if I get a subdomain from the dynamic DNS, I can point CNAME record of the domain to subdomain? But will virtual hosts work with it? I don't know. I suppose it should but it could not work also. Hmm.. lets see, I think I have done this before, apache virtual hosts works with CNAME.

But there is another issue that one of the website runs behind a SOCKS5 proxy, How will I accommodate that? The issue is that, since its Ubuntu running over VM over lineage OS in phone, I can't get low number ports such 80 or 443 so I have to somehow use Dynamic DNS and SOCKS5 proxy to redirect traffic at higher port number.

I mean, I still have oracle VPS running so I may not need virtual hosts in mobile server. So maybe I will venture this when I need it.

I am just wondering whether I should run Docker to run my game server then redirect the traffic with apache virtual hosts, reverse proxy with SOCKS5 proxy? I don't even know if it work. Theoretically it should work.

[Re]starting my self-hosting journey, and why

Day 80 - Jan 24th, 12.024

Yesterday I "woke" up my old computer as a server [again], now the fun part starts. But, why am I self-hosting?

Why self-host?

The short answer: for me, it's fun.

The long answer: to start, if you don't know what self-hosting means, here's a small explanation from our good old Wikipedia:

Self-hosting is the practice of running and maintaining a website or service using a private web server, instead of using a service outside of someone's own control. Self-hosting allows users to have more control over their data, privacy, and computing infrastructure, as well as potentially saving costs and improving skills. Source: Self-hosting (web services) - from Wikipedia, the free encyclopedia

In summary, it's like if you used your computer to run something like YouTube, instead of connecting to the internet to use it. Self-hosting can be really advantageous if you care a lot about privacy, control of your data and how it's used, not only that, but if you're a developer, you know have a lot more power in customizing, tweaking and automating services and tools that you use. And because the data and code is on your own machine, you aren't locked-in into a cloud provider, website, yadda yadda. There are people who can explain this better than me, and nowadays self-hosting isn't that hard if you know a thing or two about computers.

Personally, I plan to use self-hosting for three reasons:

Privacy and data control, of course;

Network control, aka. Ad blockers in the hole home's network with something like Adguard Home and a private intranet with Tailscale;

And, the most useful, automation. I already talked about here and there, but I hope that I can automate my social medias, daily journal publications, and things like that using my home server, specifically with something like Gitea actions (or in my case, Forgejo actions).

Maybe something like federalization also, I don't know yet how hard it would be to self-host my own Mastodon or [insert another ActivityPub-compatible instance here] on my computer.

Something which I also plan to do is to run my own Invidious and other frontend-alternatives for myself, I already use public instances and pretty much de-googled my online life nowadays, so why not try self-hosting also? Maybe even open these instances to my friends? So they can also have more private alternatives? Or maybe I'm dreaming too much? Probably.

How to self-host?

If you're somehow interested about self-hosting after this amalgamation of an explanation, and do not know where to start, I would recommend taking a look at CasaOS or YunoHost, these give you an easy-to-use User Interface (UI) to manage your server and services. I tried both, CasaOS being what introduced me to self-hosting, alongside this video on how to install it on Linux and use it.

Nonetheless, this is my third try on self-hosting, because the two previous options didn't serve my current needs and also because I'm liking the idea of using NixOS, which is how I'm configuring my home-server now. And it is being kinda great to share common configuration and code between my desktop and home-server, without counting also the incomparable control of using it instead of the docker-based solutions I mentioned (but again, I wouldn't recommend using Nix in your first try of self-hosting, even less if you don't have any experience with it or programming in general).

I already have a Forgejo instance running now, and I hope that tomorrow I'm able to configure Adguard Home on it, since these are pretty much the two main reasons and purposes of this server. Also, Tailscale is also configured, pretty much just services.tailscale.enable = true, that's it.

I have to admit, I'm kinda loving NixOS more and more, and it's also making me love even more Linux in general. It's always great to learn and try something new. Hopefully in some days I will make a more detailed post about the hole system that I'm creating to myself, it's kinda scary and interesting the scale that this "productivity system" is taking.

i need this to be the summer i actually set up using grocy and make the executive functions involved in grocery lists and finding out what to cook soooo much easier

but its still just slightly too over my head for me to figure out. id probably be fine if i had a windows laptop and bought a usb scanner and just did everything on my laptop since it has the windows desktop application

but my laptop has very limited space remaining and its a mac so i dont want to dual boot it. i guess i could look into a virtual machine just for using grocy??

but also regardless it might be nicer (and helpful for other stuff too) to self-host grocy

then i could scan from my phone and have it go to both my laptop (mac mojave) and my desktop (windows 10 but also planning on dual booting with some sort of linux soon)

but im just not sure at all how to self host it/best practices even if i did figure that out. i cant even figure out docker which so many people say makes it easier

i also have a shitty old screenless mac laptop i can connect with hdmi to a screen if needed and install w/e operating system on that maybe i could use to host stuff?? no idea if thatd be convenient or needed tho??

tech mutuals help :(

🚀 Master DevOps Automation: The Complete Jenkins CI/CD Pipeline Blueprint

In today’s fast-paced digital world, delivering software faster, safer, and smarter is not just a trend—it’s a business necessity. Whether you're a budding developer or an experienced DevOps engineer, mastering Jenkins CI/CD pipelines is your ticket to automating delivery workflows and boosting deployment efficiency.

Welcome to the era of DevOps, where integration meets automation—and The Complete Jenkins DevOps CI/CD Pipeline course is your ultimate guide to becoming a DevOps pro.

So, let’s break down what Jenkins, CI/CD, and DevOps really mean, why you should care, and how this course can change the game for your career or business. Let’s dive in!

🌐 What is Jenkins and Why Does It Matter in DevOps?

Let’s keep this simple.

Jenkins is an open-source automation tool written in Java. It helps you automate the process of building, testing, and deploying applications. Think of Jenkins as your digital assistant that works around the clock to streamline your code delivery process.

Here’s why Jenkins is such a big deal in DevOps:

💡 Automation: Eliminate manual errors and repetitive tasks.

🧱 Flexibility: Jenkins integrates with over 1,800 plugins.

🔁 Continuous Integration & Continuous Deployment (CI/CD): Push code, run tests, deploy updates—all without lifting a finger.

Whether you're working on a solo project or part of a large development team, Jenkins helps you ship quality software, faster and more reliably.

🧰 What Exactly Is CI/CD?

CI/CD may sound technical, but it’s pretty straightforward.

Continuous Integration (CI) means developers regularly push code to a shared repository. Jenkins automatically tests that code to catch bugs early.

Continuous Delivery (CD) means your application gets automatically built and deployed to a staging or production environment after passing those tests.

Together, CI/CD creates a seamless development flow that ensures your app is always in a deployable state. And Jenkins is the engine behind that flow.

In short, CI/CD = Less chaos. More control.

🚀 Why You Need Jenkins CI/CD in Your Skillset

Here’s the truth: DevOps is the future of software development. Companies want faster releases and fewer bugs. If you can offer that, you’re gold.

💼 Career Boost

Hiring managers actively seek professionals who understand CI/CD practices and Jenkins workflows. In fact, Jenkins has become a staple in almost every DevOps job listing.

⏱️ Time-Saver

Imagine testing and deploying code with a click—or even better, no clicks at all. Jenkins automates these steps, freeing up your time for more important work.

✅ Fewer Bugs

Because Jenkins automatically tests new code, you catch bugs earlier—when they’re cheaper and easier to fix.

ARMxy Based SBC Controller BL340 for Production Line OEE Monitoring

Case Details

Introduction to OEE

OEE (Overall Equipment Effectiveness) is a key performance indicator (KPI) in manufacturing that measures how effectively a production line or equipment is utilized. It combines three critical factors:

Availability (percentage of scheduled production time when the equipment is operational).

Performance (actual production speed relative to maximum theoretical speed).

Quality (ratio of defect-free products to total products produced).

The formula for OEE is:OEE=Availability×Performance×Quality

Aiming for an OEE value ≥85% is considered "world-class" in manufacturing. By monitoring OEE, companies can identify bottlenecks, reduce downtime, and improve product quality.

I. Hardware Configuration for OEE Monitoring

Data Acquisition Layer

Equipment Status Monitoring:

Use X-series I/O boards (e.g., X23/X26) to connect DI (Digital Input) signals for tracking equipment start/stop states and downtime statistics; utilize DO (Digital Output) to control alarm lights.

Deploy Y-series I/O boards (e.g., Y95/Y96) with pulse counters to collect real-time cycle times (e.g., motor RPM) for performance rate calculations.

Quality Inspection:

Connect sensors (e.g., pressure sensors, optical detectors) via Y-series AI/AO boards (e.g., Y31/Y33) to acquire defect rate data.

Networking:

Use 3x 10/100M Ethernet ports to interface with PLCs or SCADA systems for production plan synchronization; optional 4G/WiFi modules (via Mini PCIe slot) enable cloud data transmission.

Edge Computing Capabilities

Real-Time Local Processing:

Leverage the quad-core ARM Cortex-A53 CPU (1.4 GHz) to compute OEE metrics locally.

Ensure low-latency processing with the Linux-RT real-time OS (kernel v4.9.170).

Storage Expansion:

Store historical data on SD cards or 16GB eMMC for offline analysis.

II. Software System Integration

Protocol Compatibility

Built-in BLIoTLink software supports Modbus TCP/RTU, OPC UA, MQTT, etc., enabling seamless integration with PLCs (e.g., Siemens S7-1200), SCADA (e.g., Ignition), and MES systems.

Example: Validate data accuracy by combining Modbus TCP readings from PLCs with local pulse counts.

Visualization & Alerts

Develop OEE dashboards using Qt-5.12.5 or Node-RED:

Display real-time equipment status (running/idle/fault), OEE values, and historical trends.

Configure threshold alerts (e.g., trigger emails/SMS if OEE < 80%).

Example: Use Node-RED to aggregate OEE data → MQTT → ThingsBoard platform → dashboard visualization.

Cloud & Analytics

Deploy Python scripts via Docker to connect with AWS IoT Core or Alibaba Cloud:

Store long-term OEE data and apply machine learning to identify downtime causes (e.g., vibration anomalies linked to mold wear).

Example: Predict equipment failures using TensorFlow Lite models to boost availability via proactive maintenance.

III. Deployment Case Studies

Automotive Welding Line:

BL340B model (1 X board + 2 Y boards) connects to welding robot PLCs. Y95 board collects welding cycle pulses; X23 monitors emergency stop signals.

Results: 15% increase in availability (predictive maintenance reduces unplanned downtime); 99.2% quality rate.

Food Packaging Line:

BL342A model (3 Ethernet ports + HDMI) integrates USB cameras for visual inspection, directly displaying defect counts and quality rates on factory screens.

IV. Key Advantages & Scalability

Flexibility:

Expand with Y-series AI/AO boards (e.g., Y43/Y46) for high-precision sensors or Y51/Y52 boards for PT100 temperature probes.

Robustness:

Operates in harsh environments (-40°C to 85°C, IP30 rating); hardware watchdog ensures automatic recovery from faults.

Cost-Effective Upgrades:

Retrofit legacy equipment via RS485/Ethernet interfaces, avoiding full PLC replacement.

V. Implementation Steps

Hardware Setup:

Select BL340B (2 Y-slots) + SOM341 (16GB+2GB) for optimal processing power.

Install X23 (4DI/4DO) and Y95 (pulse counter + PWM) boards.

Software Configuration:

Deploy BLIoTLink for Modbus TCP PLC integration; build OEE logic with Node-RED.

System Validation:

Verify real-time data acquisition (<100ms latency); calibrate sensor accuracy (e.g., ±0.5%).

With the ARMxy Based SBC Controller BL340 manufacturers can rapidly establish a cost-effective, reliable OEE monitoring system, transitioning from "experience-driven" to "data-driven" smart manufacturing.

Cold-Pressed vs Wood-Pressed Oil: Which Method Delivers Better Flavour, Nutrition and Value?

Understanding the two traditional extraction methods

Although both methods aim to obtain oil without the high heat or harsh chemicals used in modern solvent extraction, “wood-pressed” and “cold-pressed” are not interchangeable terms.

AspectWood-pressed oil (chekku/ghani)Cold-pressed oil (general modern method)EquipmentWooden mortar and pestle (usually a slow-turning pestle driven by a bullock or low-RPM motor). The wood absorbs some heat and helps moderate the temperature.Stainless-steel or food-grade alloy screw press run by an electric motor; wooden parts are rarely involved.Operating speed & temperatureVery slow (6–14 rpm). Friction heat seldom exceeds 35 °C.Faster (30–60 rpm or more); industry standard keeps the temperature under 50 °C, but brief spikes can occur.YieldLower; about 25–30 % of the seed weight, leaving a moister cake.Slightly higher (28–35 %) owing to tighter mechanical pressure.Flavour & aromaCharacteristically nutty, robust, and closer to the original seed/nut; small wood particles can impart a mellow note.Clean, mild flavour; less variation from batch to batch.Nutrient retentionExcellent preservation of delicate antioxidants (tocopherols, polyphenols) because of minimal heat and oxygen exposure.Still good, but marginally more heat and shear can reduce some heat-sensitive components.Shelf-lifeShorter; residual moisture and the absence of added preservatives mean it should be consumed within 4–6 months.Slightly longer (6–9 months) provided it is filtered well and stored away from light.Typical marketing claim“Chekku”, “Lakdi ghani”, “Kachi ghani”. Often sold in local or artisanal markets.“Cold-pressed” on supermarket shelves; certification sometimes available (≤ 50 °C extraction).Cost & scalabilityHigher cost per litre; production is small-batch and labour-intensive.More economical at scale; suitable for medium- to large-scale bottlers.

Key take-aways for home cooks

Process distinction Wood-pressed oil is always a form of cold pressing, but it uses a wooden pestle that keeps friction – and therefore temperature – even lower than modern metal presses.

Taste and culinary use If you prefer a pronounced, almost rustic flavour for sautéing, dressings, or finishing dishes, a wood-pressed oil (especially ground-nut, sesame or coconut) is hard to beat. Cold-pressed oils offer a cleaner profile suited to neutral cooking or baking.

Nutritional edge Both retain more natural vitamins, phyto-sterols, and antioxidants than refined oils, yet the extra-low heat of wood pressing gives it a slight advantage. Either variety loses goodness when repeatedly heated above 180 °C, so reserve them for low- to medium-heat cooking.

Storage caution Because neither variety is refined, they contain fine seed sediments that hasten oxidation. Buy in small quantities, keep the bottle tightly capped, and store it in a cool, dark cupboard.

Authenticity checks Look for batch dates, natural cloudiness (not turbidity caused by moisture), and an aroma that matches the seed. A sharp or paint-like smell suggests rancidity.

Which should you choose?

For maximum flavour and a touch of tradition – choose wood-pressed, knowing you will pay a premium and need to finish the bottle sooner.

For everyday healthy cooking with a lighter taste – a reputable cold-pressed brand offers most of the nutritional benefits at a friendlier price and with slightly longer shelf-life.

Either way, both are a significant improvement over solvent-extracted, highly refined oils if your goal is to keep dishes wholesome and aromatic.

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.
