Docker on Ubuntu 22.04 LTS

My main use case for Docker on Ubuntu  has been for many reasons, running any type of application on Docker  in Kubernetes  clusters. Usually, Ubuntu  is the operating system that I use. One example is running a web application on Ubuntu  on Docker .

I have used a specific web application for marketing events where users go onto the website, place reservations for the event, and read information about the event. It's a classic web application with different web pages, and the setup I used in that example was zero to three EC2  instances on AWS  running Ubuntu and Docker, scaling based on the number of users trying to access the webpage to meet availability requirements.

The best features Docker on Ubuntu  offers include really good support as Canonical, the makers of Ubuntu, and Docker, the company, work closely together. Ubuntu is definitely the most widely used operating system for Docker, so when new features come about or security patches are released, they usually go to Ubuntu first, which is good. I have also found personally that when using documentation to build out applications, most of the documentation references using Ubuntu, making it easier. There is a lot of documentation and community support, including many Stack Overflow articles, to help someone use Ubuntu and Docker.

The performance is good, and Docker and Ubuntu are designed to work together very effectively since Docker likely chose Ubuntu as its reference OS. The functionality of the two working together is very good, and it's easy to install packages using Ubuntu's apt package manager when using Docker. If you wanted to install adjacent tools like Docker Compose or NVIDIA Docker for GPUs, it's very easy to do those types of things, and there's also a lot of documentation available on how to do it.

Docker on Ubuntu has positively impacted my organization because it really serves as a bedrock combination for building applications on top of it. You need a solid, stable base, and Docker, as a container platform, is very stable and widely used, much of like Ubuntu, making for a strong foundation to build on.

Docker on Ubuntu can be improved because Ubuntu is not minimalist at all; it comes with a lot of software by default. This has led some individuals, including myself, to try using Alpine, which is more lightweight, allowing the container to run on a more lightweight operating system that potentially uses fewer resources and reduces costs. If Ubuntu were a little more minimalist, that would be good, but it's not really aiming for that since it intends to be the baseline. Also, Ubuntu moves very fast, possibly faster than other operating systems like Debian , which could demand operational heavy upgrades to major versions every couple of years if there are many applications running.

I have been using Docker on Ubuntu for around five years.

Docker on Ubuntu is very stable. Docker is continually optimized by the Docker company, and Ubuntu is also continually optimized. They link very well together, so it's stable currently, and I imagine it will continue to be long into the future.

Docker on Ubuntu is highly scalable, but it really depends on how you're deploying Docker and Ubuntu and what you're deploying it on. Using Docker on Ubuntu together is a common configuration, and you can deploy it directly on server hardware using virtual machines or in the cloud, scaling however you wish, so I rate it ten out of ten for scalability.

My customer support experience was on AWS , and Amazon's customer support is brilliant, with very quick response times, so I give it ten out of ten.

Positive

I tried using Docker on CentOS  before, but CentOS  became deprecated, which is why I switched to Ubuntu, as I believe it won't become deprecated anytime soon due to its wide usage. So, Ubuntu is more stable for that requirement.

Before choosing Docker on Ubuntu, I evaluated using Docker on CentOS  as the other option.

My experience with pricing, setup cost, and licensing is that the costs can vary for purchasing machine images, but it's very cheap for open source operating systems like Ubuntu, and I can't remember if it was free or very low cost. It might have even been free since it's open source, making it very good.

My company does not have a business relationship with this vendor other than being a customer.

I wouldn't say that using Ubuntu and Docker directly saves money, time, or requires fewer employees. It's more about forming a baseline so that whatever application you are building on top of it can deliver those benefits. You need some type of operating system and a container engine, and these two are best in class; it allows whatever you build on top of it to achieve return on investment metrics.

I would say there are fewer errors, and organizations could see at least a ten percent reduction in their errors if they use a popular OS like Ubuntu compared to less known or less documented ones. Additionally, easier scaling is definite, as Ubuntu is very easy to use and scales nicely. Organizations can leverage cloud auto-scaling groups, leading to cost savings, at least ten percent to maybe twenty percent from the scaling.

I advise others to use Docker on Ubuntu if they have a standard use case. If they need a highly secure operating system on a container engine, they might want something more security-focused, or if they want something lightweight, they might choose Linux Alpine, but for most use cases, it's brilliant.

I give this product a rating of ten out of ten.

I use Docker on Ubuntu  primarily for containerizing applications and development environments, creating consistent runtime environments across development and testing, reducing dependency issues, and simplifying the development workflow on the Linux ecosystem.

Recently, I was working with an application for one of the Linux ALSA-based advanced Linux audio system applications, and I had to containerize that application so that we could run it on different devices and different Ubuntu  OS versions. I used Docker  for this purpose.

In some update systems, I was building some software updates, and I also used Docker  for those tasks. There are many additional cases where I have used Docker.

The best features that Docker on Ubuntu  offers are container isolation, fast startup time, portability, and strong integration with the Ubuntu Linux  ecosystem, making it easy to package applications with their dependencies and run them consistently across systems.

Portability and the isolation that containers provide are very useful, as is the fast setup. All these features of Docker are very useful because they help set up environments very quickly on other operating systems without any dependencies, which is a very valuable feature of Docker.

In the Ubuntu ecosystem, the integration is very strong, which I think is one of the best features. The compatibility of Docker with the Ubuntu system is one of the best features.

In my organization, we use the Linux ecosystem exclusively for our development, and my team's development environment is based entirely on the Linux system. We have multiple devices where the system is running. Docker helps us port our software and applications to many devices without any dependencies, such as without any other installation, pre-installed application, or library. Whatever is needed is only packaged in Docker, so it helps us port the application very quickly and very easily. Docker has definitely improved productivity and reliability significantly.

Docker on Ubuntu could be improved by making networking and storage configuration simpler, specifically for teams new to containers. Better built-in tooling or clearer documentation for debugging container networking issues would help tremendously. Tightening integration with security tooling and providing clear guidance on container hardening would be useful for production environments. Simplifying  networking and improving documentation for debugging would make Docker on Ubuntu even better.

One additional pain point is managing containers at scale. As the number of containers grows, it becomes more complex and requires additional tools. Troubleshooting container networking or volume-related issues can sometimes be time-consuming, specifically in more advanced setups.

I started using Docker on Ubuntu three years ago.

I have deployed Docker on our private server. We primarily use Docker on on-premises systems and, in some cases, in hybrid setups where development and testing may run on cloud-based environments while production remains on-premises. This approach gives us the best control over hardware, networking, and costs, specifically for embedded and system-level workloads.

In our hybrid setup, we mainly use AWS  for development and testing workloads while the production ecosystem runs on-premises, utilizing AWS  for tasks including CI/CD pipelines, container image storage, and temporary test environments. For our cloud side, we use AWS through the AWS Marketplace  combined with on-premises infrastructure for our core system.

From my experience, pricing and licensing for Docker on Ubuntu are very straightforward. Docker itself is open source and when used on Ubuntu, there are no licensing costs, which significantly reduces setup and operational expenses. When using Docker via AWS Marketplace , pricing is transparent and usage-based, making cost planning easier. Overall, Docker on Ubuntu helps us avoid vendor lock-in and reduces infrastructure costs compared to traditional VM-based deployments.

Using Docker on Ubuntu helps us save time and operational efforts rather than directly reducing headcount. It saved setup time by seventy percent, reduced VMs and infrastructure cost by thirty to forty percent, and improved team productivity without needing additional engineers.

Before choosing Docker on Ubuntu, we evaluated a few other options, including VM-only deployments and Docker on other Linux distributions like CentOS  and Amazon Linux , but Ubuntu offered better documentation, community support, and smoother Docker integration.

On a scale of one to ten, I would give Docker on Ubuntu a rating of eight.

My main use case for Docker on Ubuntu  is mostly for local development. I use Docker on Ubuntu  to run and test services, isolate containers, and keep my setup consistent. For example, I use it to run a local web application with a database so I can test everything in a containerized environment.

Docker on Ubuntu has positively impacted my organization by improving consistency and reducing setup time, which makes development workflows more efficient. From the company perspective, it saves time by keeping environments consistent and minimizing setup and configuration issues across the team.

The best features Docker on Ubuntu offers are consistency and easy setup. It helps avoid dependency conflicts and keep environments predictable. I can always isolate a service and work without affecting my system. Since I use Ubuntu  on my computer, I use Docker on Ubuntu every day in my life because I think it runs faster and I can work better.

Docker on Ubuntu can be improved because the initial learning curve could be smoother for new users. The Docker  documentation could be better with more real-world examples in the documentation, specifically end-to-end examples for common use cases. I think it is more about better integration and clear best practices.

I have been using Docker on Ubuntu for around two years.

I find Docker on Ubuntu to be stable. I started with AWS  and have no problems with Amazon Cloud.

Docker on Ubuntu's scalability is good, as both are stable and scalable. Ubuntu  is very stable as an operating system, and Docker  scales well when used properly across projects and environments. I have no problems with the scalability.

I have not needed customer support for Docker on Ubuntu.

I have not previously used a different solution before Docker on Ubuntu.

I do not have the exact metrics regarding the return on investment because I do not track that. The main return is time-saving, as it provides less setup time, fewer errors, and improved developer productivity.

I do not have a problem with the pricing for Docker on Ubuntu because I do not pay for that; my boss does. I only use the tools.

I never evaluated other options before choosing Docker on Ubuntu as I started with that.

My advice for others looking into using Docker on Ubuntu would be to follow the official documentation and practice with simple projects before using it in more complex environments. Be patient with the learning curve and be confident as you learn by taking baby steps. I would rate this product an 8 overall.
