Using Docker in Software Development

Docker has become a vital tool in modern software development. It allows developers to package applications with all their dependencies into lightweight, portable containers. Whether you're building web applications, APIs, or microservices, Docker can simplify development, testing, and deployment.

What is Docker?

Docker is an open-source platform that enables you to build, ship, and run applications inside containers. Containers are isolated environments that contain everything your app needs—code, libraries, configuration files, and more—ensuring consistent behavior across development and production.

Why Use Docker?

Consistency: Run your app the same way in every environment.

Isolation: Avoid dependency conflicts between projects.

Portability: Docker containers work on any system that supports Docker.

Scalability: Easily scale containerized apps using orchestration tools like Kubernetes.

Faster Development: Spin up and tear down environments quickly.

Basic Docker Concepts

Image: A snapshot of a container. Think of it like a blueprint.

Container: A running instance of an image.

Dockerfile: A text file with instructions to build an image.

Volume: A persistent data storage system for containers.

Docker Hub: A cloud-based registry for storing and sharing Docker images.

Example: Dockerizing a Simple Python App

Let’s say you have a Python app called app.py: # app.py print("Hello from Docker!")

Create a Dockerfile: # Dockerfile FROM python:3.10-slim COPY app.py . CMD ["python", "app.py"]

Then build and run your Docker container: docker build -t hello-docker . docker run hello-docker

This will print Hello from Docker! in your terminal.

Popular Use Cases

Running databases (MySQL, PostgreSQL, MongoDB)

Hosting development environments

CI/CD pipelines

Deploying microservices

Local testing for APIs and apps

Essential Docker Commands

docker build -t <name> . — Build an image from a Dockerfile

docker run <image> — Run a container from an image

docker ps — List running containers

docker stop <container_id> — Stop a running container

docker exec -it <container_id> bash — Access the container shell

Docker Compose

Docker Compose allows you to run multi-container apps easily. Define all your services in a single docker-compose.yml file and launch them with one command: version: '3' services: web: build: . ports: - "5000:5000" db: image: postgres

Start everything with:docker-compose up

Best Practices

Use lightweight base images (e.g., Alpine)

Keep your Dockerfiles clean and minimal

Ignore unnecessary files with .dockerignore

Use multi-stage builds for smaller images

Regularly clean up unused images and containers

Conclusion

Docker empowers developers to work smarter, not harder. It eliminates "it works on my machine" problems and simplifies the development lifecycle. Once you start using Docker, you'll wonder how you ever lived without it!

      apt:

        name: docker.io

        state: present

      become: yes

    - name: Start Docker service

      service:

        name: docker

        state: started

        enabled: yes

      become: yes

    - name: Pull necessary Docker images

      docker_image:

        name: "{{ item }}"

        tag: latest

        source: pull

      loop:

        - nginx

        - node

        - mongo

    - name: Run MongoDB container

      docker_container:

        name: mongo

        image: mongo

        state: started

        ports:

          - "27017:27017"

    - name: Run Node.js application container

      docker_container:

        name: node_app

        image: node

        state: started

        volumes:

          - ./app:/usr/src/app

        working_dir: /usr/src/app

        command: "node app.js"

        links:

          - mongo

    - name: Run Nginx container

      docker_container:

        name: nginx

        image: nginx

        state: started

        ports:

          - "80:80"

        volumes:

          - ./nginx.conf:/etc/nginx/nginx.conf

        links:

          - node_app

Conclusion

By integrating Ansible with Docker, you can streamline and automate your container management processes, making your infrastructure more consistent, scalable, and reliable. This combination allows you to focus more on developing and less on managing infrastructure. Whether you're managing a single container or orchestrating a complex multi-container environment, Ansible and Docker together provide a powerful toolkit for modern DevOps practices.

Last night's breakdown was the best one yet, I've been holding in so many feelings hehe who knew I had it in me to say such things... there's just so much to do, and thats never been a problem.

But god damn, those were some really sad things that were in my mind, things I thought I'd moved on from and things I thought were okayl

I am just going to take a break from chatting to people, maybe thats getting to me. I'm just going to do my other practicals and then focus on the project, I'll try to put in some studying for security but hey we'll see how it goes.

By the end of today I should be an expert in:

Neo4j

MongoDB

Fortran

COBOL

Computer Security

From tomorrow I'll see in developing the Orcust system for the app, thats literally my last wish for the project. What's the Orcust system you ask? Well think of it as a service that allows for user submitted code to be included into the app's system, and this is accomplished through an orchestration of docker containers.

So we're taking your code, creating a docker image from it using a template and then running it as a container on its assigned port, and the running.

The orcust system is built using python and making use of docker library for this orchestration (I think management is a better word but I like the word "orchestrate") and making use of mysql for managing each container along with their assigned ports.

You'll be able to update, each version before being accepted is tested to ensure it meets the requirements which are as follows:

The running of the app shouldn't exceed the TIMEOUT of 10 seconds

Must be able to process images of different sizes

No viruses detected in images

I'll

UYPP: Ben Ruel's Garage Garden

Back in March, we announced the winners for our Unleash Your Potential Program, in which six participants got to configure their own System76 computer to use for their awesome projects. This first awesome project is the Garage Garden, helmed by awesome project-er, engineer, and mighty green thumb Ben Ruel. We sat down with Ben to see how his project has been growing on the Meerkat.

Can you tell us about the Garage Garden project? What's it all about?

I spent a career with the Coast Guard and came up here—my final tour with the Coast Guard was in Juneau. Being in southeast Alaska, we’re constrained with what they call off-the-road systems, and the only way in or out of town is by boat or by plane. So all of our food comes up here by barge for a small nominal fee, or by aircraft for an incredibly large fee.

When I came up to Juneau with my wife and kids 11 years ago, we noticed that by the time our produce gets up here, it’s lived on a barge a week, two weeks out of Seattle, and you have no shelf life left on them. We started trying to grow food within the first year of getting here, and we came to the conclusion pretty quickly that with 300 days plus of rain every year, outdoor growing wasn’t really a viable option. That’s when we started a hobby farm in a garage growing some stuff in soil under fluorescent lights, as odd as that sounds.

Since then, we’ve progressed into hydroponics, but we’ve done it very manually. We go out every other day and take readings by hand, so I’ve been doing some research about building IOT devices that will talk back and automate some of the readings. My dream would be using it to actually control the concentration of nutrient solutions that we use. The overall goal is we’re going to build the hydroponic monitoring network of IOT devices, and use the Meerkat as a control center for the devices and a repository for all the data. We’ve also been doing some investigating behind the scenes into whether or not it could grow enough legs to become a business.

Is there a specific type of produce that you’re starting with?

We’ve been all over the road. Right now we’ve got lettuce. We’ve always got some kind of green leafy vegetables whether it’s any variety of lettuce that will grow hydro, some bok choy and tatsoi, and we’re growing kale like it’s going out of style. We’ve grown cucumbers to the point where I think I’ve harvested 65 pounds of cucumbers off of 4 plants over the last couple of months, but we’re really constrained by our size.

I live in a relatively small 3-bedroom house, and we’re just using a one-and-a-half car garage as our grow area. Right now I’ve got two tents. As funny as it sounds, cannabis is legal in Alaska and has been forever—my wife and I don’t touch the stuff, but because it’s been legalized, the infrastructure and the supplies that we need are freely available. We’re growing tomatoes in a tent that’s designed for marijuana growth. It works really well. It helps to maintain efficient temperature control; you can maintain temperature and humidity, block out extraneous light if you don’t want it, and cycle the lights on and off.

Depending on whether it’s too hot in the summer we’ll run the lights at night, and in the wintertime we’re looking for extra warmth, we can shift the cycle and run the lights during the day. Our big benefit up here is that, because Juneau’s all on hydroelectric power, electricity is really cheap.

What variables are being monitored?

With hydroponics, there’s a good number of parameters that you’ve got to try and keep track of. You’re basically diluting nutrients in a solution of as pure water as you can get. You want to keep track of things—your pH can’t be too acidic or too alkaline, for example.

The other big parameter is the electrical conductivity, or total dissolved solids. You want to make sure you’ve got the right concentration of nutrients, and that your nutrient solution isn’t salting up. As you’re adjusting pH back and forth, it’ll start demineralizing salt, so tracking that data gives you a good indication for when it’s time to dump the reservoir and start over.

We’re doing it manually now. I go out every couple of days and we take samples, and sit down and log it into a spreadsheet. The Meerkat acts as a control center for programming devices, keeping a repository of the programming for the IOT devices that we’re using (Arduinos with the esp8266 chips) as well as running different database programs as Docker containers, so that they can be spun up and knocked down fast enough as we try and figure out what the best way to move forward is. We’ve got a couple of database servers that I’ve been playing around with, trying to break from traditional SQL and looking at NoSQL type of databases.

I’m not an IT guy by trade. I’m more of an electronics guy, so I’m kind of doing it as a study-by-night type of project.

What has your experience been like with the Meerkat so far?

I’m actually completely blown away by the Meerkat’s performance. It’s astounding what that small form factor and footprint is able to do. I’ve used Linux for a number of years, and basically everybody’s heard of System76. I’ve seen Pop!_OS before and never really played with it all that much, but I’ve actually grown to love it. The feel, the ergonomics, the interface, and even down to the color schemes that come bone-stock right out of the box. They just make more sense to me. I’m looking forward to the COSMIC update after researching that to see how the differences in the workflow will affect things.

What software are you using for this project?

Right now we’re writing in Docker containers and running the Tick Stack from Influx. We’re also running Telegraf, Protograph, Capacitor, playing around with the Time Series Database, I’ve got a container running MongoDB I run with SQLite, and there’s a couple different IDEs I’ve got loaded on there as well for programming Arduinos or esp8266 chip flashing.

How was the setup process for the machine?

It was up and running within 10–15 minutes of pulling it out of the box. I actually took it to work, too. We do a lot of work with government agencies, and I’ve been doing a lot of microwave radio repair. I’ve got a pretty small workbench at our shop here in Juneau, so using the Meerkat to drive all of our test equipment to control the radio while logging data coming out of the radio, it was perfect. It had enough horsepower to remotely control the test equipment. I wasn’t pushing it all that hard, but setting it up and going back and forth between having it at home or at work, it was negligible to get it up and running.

Stay tuned for further updates from Ben Ruel’s Garage Garden and cool projects from our other UYPP winners!

6 ESSENTIAL SKILLS FOR AWS DEVELOPERS

AWS is the 500-pound gorilla in the room of cloud stages. Regarding piece of the pie, AWS claims a greater amount of the cloud market than its nearest four rivals joined. The pervasiveness of a solitary stage implies that when engineers are on the lookout for a new position, there's an amazingly decent possibility that they'll discover "AWS" under the ideal abilities for designer jobs. By having a firm comprehension of AWS improvement, you'll separate yourself and become profoundly esteemed in your group or organization. The measure of administrations and usefulness in AWS can be overpowering; this article reduces the most fundamental abilities you should know as an AWS designer.

1. Deployment

So you've composed a web application, presently what? Sending web applications to AWS is perhaps the most essential, and probably the most profound expertise to know as an AWS engineer. There are different approaches to convey to AWS, yet they keep on developing as new strategies arise and more established ones are the sunset. On account of this advancement, the accompanying outline of AWS arrangement strategies ought to be checked to ensure there aren't fresher techniques recommended.

In the first place, you ought to be agreeable to physically convey a web application to an EC2 occurrence. Understanding this establishment will permit you to expand on it and conceivably make your own mechanized sending scripts.

Then, you should know CloudFormation well and see how to utilize that to send an application, yet in addition, stand up your application framework. You ought to likewise be acquainted with Elastic Beanstalk and the work it accomplishes for you. The jury is as yet out on whether EB is the awesome most exceedingly terrible help for conveying applications to AWS, yet it is utilized at a ton of organizations so realizing it is a smart thought.

At last, compartments are turning out to be increasingly mainstream, so realizing how to convey applications with Elastic Container Service (ECS) for Docker or Elastic Kubernetes Service (EKS) for Kubernetes is getting increasingly fundamental.

2. Security

The force of AWS is at times a two-sided deal. In spite of the fact that it permits you to do a ton, it likewise doesn't hold your hand. Acting naturally dependent and understanding the intricate details of the AWS Security Model and IAM is fundamental. Regularly, the most well-known bugs and issues that emerge in AWS come from a misconception of IAM by engineers. Getting very acquainted with how Roles and Policies work will upgrade all aspects of your AWS work.

Privileged insights the board is likewise another interesting subject that emerges regularly. AWS dispatched another assistance a year ago—properly called Secrets Manager—that truly removes the intricacy from overseeing and recovering any insider facts (like API keys, passwords, and so on) in your web applications.

3. AWS SDK

The AWS Software Development Kit (SDK) is the manner by which your application will communicate with AWS in the code. The API layer is totally gigantic in the SDK; even as an expert, you will continually discover new things that can be cultivated with it. Being acquainted with the SDK will deliver profits, on the grounds that interfacing with AWS won't be new to you. It's regular for engineers to not realize where to begin when pulling down an article from an S3 pail or associating with a DynamoDB table. Try not to be that designer. Get some involvement in SDK and perceive that it is so natural to utilize perhaps the most impressive advancements on the planet.

4. Databases

Data sets are a fundamental piece of each web application and AWS has various choices for fulfilling that utilization case. The issue is sorting out which information base assistance is ideal for your application. Without seeing every one of the alternatives and a portion of the advantages and disadvantages, you risk picking some unacceptable choice and blocking your application's development.

Investigate the current alternatives accessible in RDS. Aurora proceeds to improve and add new layers of similarity with MySQL and PostgreSQL. Attempt to comprehend why you should utilize Aurora rather than different alternatives. DynamoDB keeps on being a well-known decision for fast and straightforward NoSQL data set requirements. Perhaps the best part is its REST-based API, which implies no long-running data set association is required. At last, DocumentDB is the new child on the AWS information base scene, giving MongoDB similarity. Assuming DynamoDB doesn't work for your archive data set requirements, DocumentDB may get the job done.

5. Debugging

Assuming you're a designer, you know how baffling hitting a detour can be. However, you additionally likely ability a lot simpler it will manage barriers after you have some experience defeating them. AWS is the same in such a manner. Each time you conquer an issue in AWS, it just makes investigating and fixing the following issue that a lot simpler. Tragically, there's no guide to troubleshooting. It truly takes getting in there and acquiring experience with AWS. Albeit most issues you'll experience will probably be either identified with IAM consents or VPC bases access rules (for example Security Groups), there's simply no substitution for getting into the stage and creating. You'll run into issues and uncover yourself. Consider that experience when you experience your next issue to have the option to investigate it successfully.

6. Serverless

Serverless administrations in AWS, like Lambda and API Gateway, are taking care of an ever-increasing number of designer's issues nowadays. Getting when and for what reason to utilize them is a fundamental ability for each AWS engineer. Serverless engineering is extraordinary for specific sorts of usefulness and you ought to do research and evaluate this kind of design. Since Serverless is a new methodology, it's not generally comprehended by more prepared designers. By acquiring some involvement in this new innovation worldview, you can separate yourself in your group and in your organization. An open-source structure that makes building applications on Serverless engineering such a ton simpler is the Serverless Framework. By using Cloud Formation and the AWS SDK, this system permits you to utilize straightforward design records to construct incredible Serverless innovations.
