Docker on Ubuntu Reviews

I do have experience with Docker on Ubuntu. I have used Docker for testing in production; however, I haven't worked with Docker on Ubuntu directly. I have also used K3s, the mini Kubernetes distribution, for educational and testing purposes.

The overall main point of Docker on Ubuntu is the ability to have just what you need to run your application instead of having a complete server with all the libraries and security configurations. Docker on Ubuntu allows you to use a container with the specific application that you need to solve your problem. That is the real power of Docker on Ubuntu.

Microservices management on Ubuntu platforms is very powerful because you can split the components into microservices. I have to be honest; I'm not an expert in microservices architecture. I know the main concepts, but I don't have very deep knowledge in this architecture.

The area for improvement with Docker on Ubuntu is normally the complexity of the networking or DNS. It is completely complex to understand the networking in Docker on Ubuntu and Kubernetes clusters, as well as the ephemeral nature of the network and storage, which are topics that need to be understood very well.

I have experience to discuss Docker on Ubuntu and can share my thoughts about it.

Docker on Ubuntu features align completely with my continuous integration pipelines on Ubuntu. In some cases, Docker on Ubuntu is not enough for all the complexity of the applications, and I have to go to the next level with Kubernetes. However, depending on the kind of application, it is enough for some companies. In some cases, companies feel very frustrated because they cannot scale, and when they want to scale, they face the complexity of Kubernetes, and the cost on AWS, Azure, or any other platform is not cheaper than they think. The suitability depends on the kind of organization; it's not for all companies.

The customer service for Docker on Ubuntu and their technical support are pretty good, especially since the documentation is pretty robust. The company behind Ubuntu, Canonical, is a community project, and they provide a lot of documentation and very good support. I have worked a couple of times with the team from Canonical, and they are very proficient in technical matters.

I find the pricing for Docker on Ubuntu is not expensive because basically, it is zero. The cost is much more related to the knowledge and experience that people need, which means cost because not all engineers have experience with this platform. For me, it is zero, but in normal implementations, it could be costly as there are not many people experienced with this platform here in Colombia.

Docker on Ubuntu access controls do help improve application security on Ubuntu, but Docker on Ubuntu per se is not safe because many software and products were conceived thinking of the solution to the problem they were trying to solve. It is necessary to harden the platform because it is not naturally safe. My overall review rating for Docker on Ubuntu is ten out of ten.

My main use case for Docker on Ubuntu is containerizing applications to simplify deployment and ensure consistency across environments since I often need to switch between them.

A quick specific example of an application I have containerized using Docker on Ubuntu is testing application configurations across multi-service deployments using Docker Compose.

Using Docker Compose for those multi-service deployments helps with my workflow since it makes the deployment much easier as I can deploy all of my services in one single file.

I also use Docker on Ubuntu as part of automated workflows and CI/CD pipelines.

The best features Docker on Ubuntu offers are its strong points of portability, consistency across deployments, and ease of deployment.

Out of portability, consistency, and ease of deployment, I rely on consistency the most in my daily work since I often need to deploy the same image across different instances, so I need all of them to be exactly the same.

Docker on Ubuntu has positively impacted my organization by helping a lot in shipping our applications since it is our main way of shipping them.

It has helped by reducing deployment times significantly since we basically configure the Docker on Ubuntu images to always have the same configuration, so we do not have to be constantly configuring those same settings since they are already configured by default in our images.

Docker on Ubuntu can be improved because it can get quite tricky, and the learning curve is quite steep, especially for beginners who are new to the concept of containerization.

I would also add that using Docker on Ubuntu by itself in complex deployments can be quite tricky without the use of orchestration tools, so the use of orchestration tools along with Docker on Ubuntu is kind of a must, and debugging can also be quite difficult.

I have been using Docker on Ubuntu for almost eight years now.

Docker on Ubuntu is stable, very much so.

Docker on Ubuntu is scalable by itself, but it is even more scalable when used with orchestration tools like Kubernetes.

I have never had to rely on customer support since I use the open-source version, but the community support is very strong.

Before using Docker on Ubuntu, we relied on manual deployments, which is not a solution per se, and we switched to Docker on Ubuntu because of much faster deployments, the consistency across different deployments, and easier management.

My experience with pricing, setup cost, and licensing is that since Docker on Ubuntu itself is open source and free to use, I haven't had any experience with its pricing; the only pricing that comes with Docker on Ubuntu is the infrastructure, and if you opt for enterprise features.

I do not have any numbers, but shipping with Docker on Ubuntu has saved us countless hours, and therefore we can operate many more deployments with fewer engineers, so you save a lot in time and personnel.

Before choosing Docker on Ubuntu, I did not evaluate other options.

My advice to others looking into using Docker on Ubuntu is that Docker on Ubuntu is very powerful and vast, so getting to know the best practices, especially around security and networking, is a must to get the most value out of it. I would rate this product a 9 out of 10.

My main use case for Docker on Ubuntu is running containers and projects that are in containers, containerized projects.

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.

The best features Docker on Ubuntu offers probably include process isolation in general, and it is easy to use and super straightforward.

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.

Docker on Ubuntu can probably be improved in the UI part. I was part of the Docker testing team, and they have a public testing team. There are some improvements to UI and probably making Kubernetes a bit more integrated, I would say.

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 have been using Docker on Ubuntu for at least four years.

Docker on Ubuntu is stable.

The scalability of Docker on Ubuntu requires Kubernetes. It is pretty much impossible to scale without it.

I have never contacted customer support.

We did not use a different solution. It was always Docker.

I have seen a return on investment, with a lot of time saved due to faster CI/CD builds and deployments, much cheaper storage due to registries, and a much easier to use general architecture. For example, in my company before Akamai, Docker was a must have. It saved so much time, so much effort, and so much human resources. It is just difficult to explain. It was super useful.

My experience with pricing, setup cost, and licensing is that technically, I did not use the paid version of Docker. This is a very seldom use case as very few organizations and very few people actually need a paid Docker. 99.9% of people will be happy with the open source version, which is open source and free.

Before choosing Docker on Ubuntu, I did not evaluate other options. It really depends, but there are no really super huge competitors. It is just Podman, but it is a different thing for different cases. It is not that simple with Podman. There are just no proper competitors that are as huge and as famous as Docker is.

My advice to others looking into using Docker on Ubuntu is to learn the containers as this is really cool technology.

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 containerizing our applications, hosting them, and performing deployment.

A specific example of an application I have containerized and deployed using Docker on Ubuntu is our multi-tier applications, including front-end, back-end, and database applications that we have hosted on Docker.

Docker on Ubuntu has positively impacted my organization because we are deploying applications as quickly as possible and can deploy to multiple clouds. Using Ubuntu, we do not need to use multiple operating systems.

My deployment process has improved and become faster and more efficient.

In my opinion, the best features Docker on Ubuntu offers are stability with reliable support and a huge ecosystem that works with Docker, Kubernetes, Docker Compose, and Jenkins. It is also cloud-friendly with AWS, Azure, and GCP, and it has community support and better compatibility compared to CentOS.

Out of those features, I rely mostly on the huge ecosystem and its cloud-friendly nature with AWS and GCP, which allows us to host our applications on multiple clouds.

Docker on Ubuntu can be improved due to hidden security concerns, as Docker runs as root by default and needs hardening through rootless user mode and privilege limiting. It has memory and CPU pressure when using too many containers, and it is complex with volumes, networking, and multi-stage builds.

It needs to harden rootless mode because it runs as root by default, so this improvement is necessary.

I have been using Docker on Ubuntu for two years.

Docker on Ubuntu is stable.

The scalability of Docker on Ubuntu is good because if you want to add more resources, you can spin up new resources by creating a container.

I hope the customer support will be good and rate it an eight.

We have been using virtual machines, but they were expensive for us, which is why we switched to Docker.

My experience with pricing, setup cost, and licensing is that Docker does not have licensing, and for pricing, you only need to pay for the virtual machines or servers you host.

We do not have any business relationship with this vendor other than being a customer.

I have seen a return on investment because money is saved after switching from virtual machines, as we previously needed to pay more for them.

My experience with pricing, setup cost, and licensing is that Docker does not have licensing, and for pricing, you only need to pay for the virtual machines or servers you host.

Before choosing Docker on Ubuntu, we had a clear mindset that we wanted to use Docker, so we did not evaluate other options.

My advice to others looking into using Docker on Ubuntu is that if they want to Dockerize an application, want a lightweight solution, create multi-stage resources, use fewer resources, and do not want to pay for virtual machines, they can use Docker and containerize their applications.

I gave this review a rating of eight out of ten.
