Docker on Ubuntu 22.04 LTS

One of those containerized projects is the monitoring stack build, which includes Prometheus, Alertmanager, and Grafana , and it is a really quick thing to run, install, and test. I am using it mainly for tests around the monitoring.

There are actually multiple use cases during my career with Docker on Ubuntu . It was building containers in the CI/CD, and Ubuntu  instances actually ran Docker  and all the builds and pushed the artifacts to the registries. There were use cases with the projects themselves being containerized, and all various cases. Pretty much everything in modern Linux ecosystems requires Docker .

Process isolation has helped me in my work for many reasons, such as the ability to give a specific amount of resources to a process, and the fact that a process does not interfere with other processes. There are multiple advantages to this, but this is generally a container thing.

There are actually great multiple things about the features of Docker on Ubuntu. If we take Ubuntu  desktop and Docker desktop, we can see that it has a really great application with many features, including Kubernetes  integration, CVE scanning, an easy to install and easy to use UI, the image manager, and all of these things. Docker is super powerful with modern Linux, especially with the industry standard such as Ubuntu.

Docker on Ubuntu has positively impacted my organization by enabling us to be a modern company that uses a modern architecture approach. It is difficult to do this without Docker.

The impact of Docker on Ubuntu includes improvements in speed, efficiency, and resource management, especially noticeable in our CI/CD pipelines. If we build the containers, it is much easier to distribute our application. It is much easier to install, configure, scale, and do pretty much everything. Without this proper containerization, the projects would work worse, there would be fewer options for deployment, and so on.

I would not add more about the needed improvements as it is difficult to tell. There are no improvements needed for Docker on Ubuntu that I have not mentioned.

I do not have any additional thoughts about Docker on Ubuntu before we wrap up. I would rate this product with a review rating of ten.

My main use case for Docker on Ubuntu  is to build Docker  images for both ARM and AMD architectures, as well as maintaining those Docker  images and the registry.

In my daily work, I have a workflow where I build Docker images on an Ubuntu  runner or GitLab  runner. Apart from GitLab  runner, I also utilize the Jenkins  pipeline where we have an Ubuntu  image with Docker in Docker. It builds the image and pushes it to our ECR. We maintain some of our servers that have Docker Swarm, which are also Ubuntu-based.

The best features that Docker on Ubuntu  offers include a copy-on-write strategy, as well as having everything in one place. For example, all the Docker registry and Docker images are in one place where we can access them. There is also the ability to add users to the Docker group so that they can run it directly without using sudo permissions, which is one of the best features that I find.

Of the features I mentioned, the one I rely on most day-to-day is the Docker build step, including multi-arch build as well as multi-stage build. I rely on it on a daily basis because our entire infrastructure runs on Docker as well as Kubernetes , which depends on Docker. I definitely rely on it heavily.

Docker on Ubuntu has positively impacted my organization by making our CI/CD pipeline faster because of the multi-stage build, multi-arch build, and the strategy of layering. We don't need to build it again and again. We can use cache for it and write Docker files as well as test them on our local machines. That is one of the best features that we have.

I have definitely noticed time saved and faster deployments.

Docker Desktop requires opening it again and again when we want to build. If there were a way to run the engine on the backend side, that would be very helpful.

Docker on Ubuntu is pretty much smooth and really helps a lot.

I have been using Docker on Ubuntu for 10 years.

Docker on Ubuntu is very much stable; it is one of the most stable solutions that you can find.

Docker on Ubuntu's scalability is highly impressive in the form of Docker Swarm or Docker Compose, scoring 10 out of 10 on scalability.

I have not used the customer support yet because I have never needed one, but the documentation is pretty much simple to understand and fix issues.

I have not previously used a different solution.

My experience with pricing, setup cost, and licensing is pretty much simple because Docker does not have a license and there is no pricing for it. The steps are provided, and we have a shell script written by Docker that you just run, and it does the automatic work for you. It is very much simple.

I have seen a return on investment with definitely time saved as well as fewer employees needed because we don't need to maintain the Docker Swarm again and again. There is a pipeline for it, and the time saving occurs because whenever a developer pushes anything, that goes into the Docker container and builds it. It is pretty much time saved, as well as money saved itself.

We did not purchase Docker on Ubuntu through the AWS Marketplace  because Docker is free of cost. We just set it up there.

Before choosing Docker on Ubuntu, we evaluated some options including Podman.

We chose Docker on Ubuntu over Podman because Docker was pretty much simple, and it was also one of the buzz topics going on. Additionally, there were people who were using it, which made it pretty much simple to interact with them and gain knowledge about how things are working.

My advice to others looking into using Docker on Ubuntu is to use it. Once you start using it, there is no going back; it is pretty much simple to use. Definitely, it is one of the easiest tools available for containerization. I would rate this product as a 9 out of 10.

My main use case for Docker on Ubuntu  is a mixture of all aspects. Since I am currently learning it, I have chosen Ubuntu  because it has very low infrastructure cost, is free and stable, has better cloud compatibility, and enables easy automation and scripting with faster DevOps workflows. Docker on Ubuntu  aligns Dev, QA, and CI on the same Linux base.

A specific example of how I use Docker on Ubuntu in my learning and projects is that every day I use the Ubuntu  terminal for automation, run Docker  containers for test services, debug issues at the OS and application level, and work closely with CI/CD on a Linux agent. It has now become a daily part of my SDET flow.

The best features Docker on Ubuntu offers in my experience is the compatibility without having to rely on any other software on Mac machines or Windows. Ubuntu itself helps stabilize the commands. I learned this through a cloud-based e-commerce test automation platform where there was user authentication, product catalog, cart, and checkout functionality. I held the responsibility of designing the automation framework, containerizing the test services with Docker , and integrating into CI/CD pipelines. I used Ubuntu as the base, then ran Jenkins  and test agents on Ubuntu, wrote all the scripts and test environment.

The combination of Docker on Ubuntu has made my automation framework and test environments better compared to other approaches I have tried. I followed various user reviews that all recommended going with Docker and Ubuntu if I wanted something scalable and deep knowledge. I followed this guidance and invested in a course. While going through this course, I learned the tools I use, including Ubuntu version 22.04, Docker and Docker Compose, Pytest, Selenium, Jenkins , Git  Bash, and Nginx. This reduced my environment setup by 70 percent, improved my test stability, and enabled faster and safer releases. I use Docker on Ubuntu in a cloud-based e-commerce automation project where I containerize test services and run them on Linux CI agents to ensure consistency and scalable testing.

Docker on Ubuntu has positively impacted my workflow primarily through low infrastructure cost, better cloud compatibility, and faster DevOps workflows.

Currently, there is nothing which can be improved about Docker on Ubuntu based on how much I have learned. I feel it is great, and my progress depends on how I can use it further.

I think the Linux setup is something that is still nowadays a bit difficult compared to Windows. I think this is not in the hands of Docker on Ubuntu or the course. I think it is something related to how Linux comes. Once it becomes easier or has a GUI interface or a more straightforward approach to install Linux, then I think everything will be easy.

I have been using Docker on Ubuntu specifically because Ubuntu gives a stable and open-source developer-friendly OS, making things easier like installing and managing dev tools, and running Linux native services. As a developer, I always want to go with Linux because it gives me all the freedom of using tools without restrictions, unlike Windows and macOS.

Docker on Ubuntu is very stable in my experience.

Docker on Ubuntu has great scalability. There are no parameters to follow or user-specific requirements unless there is a huge amount of operations going on in the database. Docker helps to reduce the dependencies across different machines. I think it is very stable.

I have not needed customer support for Docker on Ubuntu, and I have not used any community.

Earlier, I used a different solution before Docker on Ubuntu, which was Windows. Now I have been using Ubuntu. Ubuntu is more scalable and gives a different coding feel. A few other parameters also exist which cannot be disclosed. Ubuntu is much better.

Docker on Ubuntu helped with faster workflows by providing better automation in the pipelines and more reliable deployments. The testing environments, which were hectic to set up before, are now very well managed by Linux automation frameworks and testing agents in the Docker files. From this course, I learned to create Docker files for test frameworks, share container setups with teammates, integrate Docker into CI pipelines, and document how to run services locally with Docker so that others could adapt easily.

Before choosing Docker on Ubuntu, I checked other options and courses as well. After seeing the reviews, I decided I wanted to try Docker on Ubuntu only.

I would say to others looking into using Docker on Ubuntu that they should always try different approaches. If someone is on Windows or Mac, they should always give Ubuntu a try as well. I have given this review a rating of 8.
