Docker on CentOS Reviews

My main use case for Docker on CentOS is for a containerization platform, packaging applications with their dependencies for lightweight and portable containers.

A quick, specific example of how I use Docker on CentOS for containerization is that we have dockerized our frontend, backend, and database into containers, and we have hosted them using Docker on CentOS. We have multiple software images for availability and for application uptime, and it is lightweight.

The best features Docker on CentOS offers are its lightweight and fast nature, with containers sharing the OS kernel, making it faster than VMs and providing quick startup time. It also ensures a consistent environment where applications will work on every machine, not just the developer's machine, and offers resource efficiency, such as no full OS per application, allowing me to share my infrastructure with multiple containers and applications. Additionally, it provides easy deployment and scaling.

The most valuable features to me in my daily work are all of the following: lightweight nature, consistent environment, resource efficiency, and easy deployment. We do not need to worry about our source requiring more memory; it is lightweight and fast, and the deployment does not take much time. If we want to scale our infrastructure, we can just create a new Docker image and it will scale, so all of those features are important to us.

Docker on CentOS has positively impacted my organization because we do not need much resource per application, and our deployment time has decreased, allowing us to avoid using more VMs to host our applications. Regarding the decrease in deployment time, I am saving 30 to 40 percent of our time, and before Docker, we had been using 10 to 20 VMs, but after that, it has become half, approximately 10 or 11 VMs.

Docker on CentOS can be improved by addressing security concerns, such as sharing the kernel, which leads to weaker isolation than VMs. Sometimes misconfiguration can happen, such as using ports or other networking issues. Currently, as I have heard, Docker on CentOS is not officially supported, so I am considering whether there are alternatives or not.

I have been using Docker on CentOS for two years.

Docker on CentOS is stable, but as I mentioned, there are some improvements needed, and after that, I hope it will be good.

Docker on CentOS's scalability is good; if we need more resources, we can just spin up a new Docker image, so scalability is good.

I previously used VMs, but they were expensive, and it was an overhead for us to manage, so that is why we switched to Docker on CentOS.

After switching to Docker on CentOS from VMs, I have seen a return on investment, saving 40 to 50 percent of our money as well.

My experience with pricing, setup cost, and licensing is that there is no licensing in Docker on CentOS, and the setup is easy; we just need to create the images for our application, so it is easy.

Before choosing Docker on CentOS, I did not evaluate other options because we had a clear mindset that we wanted to use Docker on CentOS. We saw the public review, so that is why we thought we wanted to use Docker on CentOS only.

My advice to others looking into using Docker on CentOS is that if they want to containerize an application, make their deployment easy, avoid VM management overhead, and save costs, they can use Docker on CentOS. I would rate this product an 8 out of 10.

My main use case for Docker on CentOS is building a proof of concept web application for a few months.

In my opinion, the best features Docker on CentOS offers are limited right now due to its deprecation about a year and a half ago, which presents a lot of security risks. However, it previously had a huge documentation base because it was the industry standard for years, was very resource-efficient, and had a reliable file system from being derived from Red Hat Enterprise.

Docker on CentOS did not benefit my organization all that much because it was in a deprecated state when I was using it, which is why I quickly stopped using it due to the security vulnerabilities.

If Docker on CentOS were still actively supported, I would want to see security vulnerabilities patched since it has been deprecated for the last year and a half and to ensure that networking sections or commands do not conflict with Podman, which Red Hat now promotes.

I have been using Docker on CentOS for a few months.

In my experience, Docker on CentOS is not stable anymore because it is not actively being maintained.

Docker on CentOS is scalable; I can build virtual machines, EC2 instances, and scale from zero to however many I want, but it is not advisable due to its deprecated state.

I did not reach out for support specifically about Docker on CentOS, but I utilized Amazon's underlying AWS support, which is good and has quick response times.

I previously used Debian with Docker, which is actively maintained, and I was reading some old documentation recommending CentOS when I started using it.

I did not purchase Docker on CentOS through the AWS Marketplace, but rather through the EC2 section of the AWS console.

I have not seen a return on investment because the deprecation made it so there was none, and if anything, the ROI would have been negative since money and time were spent using something that did not progress.

My experience with pricing, setup cost, and licensing was all good; cost was never an issue, but security and deprecation made it a bad idea to use.

Before choosing Docker on CentOS, I considered using Debian because it seemed quicker and more efficient based on the documentation, but in the end, it turned out less efficient as I had to switch back to Debian.

A quick specific example of how Docker on CentOS helped with my weather application proof of concept is that I was running a proof of concept to build a web app on CentOS on Docker on EC2 instances in AWS, but I realized quite quickly that CentOS actually became end-of-life in 2024, which led me to stop using it due to its deprecated state.

Those features helped me specifically during my project by making it more stable since it used less resources, resulting in a cost-efficient deployment, as the machines that I deployed it on used less of the resources than I thought they needed.

A lesson learned during that period that impacted my future decisions was to understand the development or deprecation timelines of all different types of software pieces in my stack and also to pay more attention to the organization's direction, as Red Hat was making it clear they wanted to switch away from CentOS 7 towards CentOS Stream.

My advice to others looking into using Docker on CentOS is not to use it because it is deprecated; instead, they should opt for something that is actively being maintained, such as Ubuntu or Debian.

I gave this review a rating of 7.

My main use case for Docker on CentOS is for a microservice container service with a Kubernetes orchestration cluster service. I create cluster services for databases, for example Postgres, and services for telecommunication companies, such as Kafka service, HAProxy service, and other services within the company.

The main use cases for Docker on CentOS are to reduce costs for the company because container services cost significantly less compared to virtualization services.

The best features Docker on CentOS offers include the price compared to other services, such as OpenShift container service. The pricing is competitive and very stable.

CentOS is a fork of Red Hat, and Red Hat is an excellent operating system for a company. Docker on CentOS has positively impacted my organization by reducing operation costs, providing more reliable service, and saving money for the company budget and on other tools.

Docker on CentOS can be improved as a solution service in many companies around Latin America. Regarding Docker on CentOS's AI capabilities, I think its accuracy and reliability of output are less because CentOS, if you want to use the latest version such as number seven, is not compatible with some drivers or libraries for AI.

I have been working in my current field for four years.

Docker on CentOS's governance and security services are better than others.

CentOS at this moment does not have support, only CentOS Stream, while you can use other applications like Ansible for governance and security services.

My advice for others looking into using Docker on CentOS is that it significantly reduces the time to deploy services, making it very fast within the company. I would rate this product an 8 out of 10.

My main use case for Docker on CentOS is running containers for different application webs. For example, I run a Moodle or different APIs and microservices that are developed in Docker on CentOS.

Before Docker was very complicated. Doing the testing with the developer, and with Docker it is very fast to deploy the different changes.

I find working with APIs and microservices in Docker on CentOS to be very useful and very practical. Docker is fast, lightweight, and makes apps run the same everywhere without problems.

On CentOS, Docker provides the same core features as other Linux systems, which is not very special, but I can run containers, manage images, store data, and deploy apps.

I mainly rely on container images and volumes every day in Docker on CentOS, plus networking when apps need to connect. For example, volumes are essential when I need to keep data persistent, like databases or logs.

Docker on CentOS has positively impacted my organization by helping us deploy faster, avoid environment problems, and make the system more reliable and easier to manage.

With Docker deploying faster, we save approximately 30% of the time on production issues or in the pipelines, which are specific outcomes I have observed.

Docker on CentOS can be improved with better security, easier storage management, and smoother integration with CI/CD and orchestration tools.

I think better monitoring, easier debugging, and more standard behavior across environments will make Docker on CentOS even better.

Other improvements needed for Docker on CentOS include improving compatibility, security scanning, easier default setup, and clear enterprise documentation, for example.

I have been using Docker on CentOS for about four years.

Docker on CentOS is stable.

Docker on CentOS has super scalability with Kubernetes, but it also has scalability without Kubernetes.

I previously tried containers on Ubuntu, but I quickly changed to Docker on CentOS.

I have only seen a return on investment in terms of time saved because I save my time, but in economic terms, no, because it was free.

My experience with pricing, setup cost, and licensing for Docker on CentOS is that it is free. The licensing is free, so it is very good.

Before choosing Docker on CentOS, I evaluated other options such as Docker on Ubuntu or virtual machines.

My advice for others looking into using Docker on CentOS is to start simple, use trusted images, which is very important, learn networking and volumes, and focus on security and monitoring. I would rate this product a 7.

I don't have any specific use case with Dell PowerEdge. I work with it as a server where we install software and run Red Hat Enterprise.

I work with Red Hat Enterprise Linux 7 and 8, but I don't specifically use Red Hat OpenShift or Red Hat JBoss.

Docker on CentOS has improved my organization positively. The benefits are significant as it is easy to operate and maintain, making it more flexible. You can change any service in the system, delete or remove the service port, and create new ones.

It is difficult for me to suggest improvements because the current functionality meets my needs.

To achieve a higher rating of 9 or 10, they might need more automation features.

Docker on CentOS is quite stable. I would rate it 8 or 9 out of 10.

I rate their support as a partner. We purchase the software and product from them, so when I have an issue with Red Hat or Docker on CentOS or Kubernetes, I create a ticket with the partner who works directly with the respective teams.

I have experience with their support through a few cases requiring Red Hat assistance. I go through our software partner who communicates with the Red Hat team, and they communicate with Docker on CentOS or Kubernetes team to resolve issues.

Positive

The initial setup of Docker on CentOS is not too difficult. We can accomplish it very generally.

I don't have experience with Docker on CentOS pricing. Since Docker on CentOS, Kubernetes, and Red Hat are open source, I believe the cost is only applicable for support services.

I don't have experience with Dell PowerStore as I haven't worked with it. I am not familiar with PowerStore or its function.

I haven't worked with Dell Data Protection or DPA. My experience is limited to servers, switches, and EMC Unity storage.

The orchestration and CI/CD process relates to the architecture engineer and solution architecture.

I rate Docker on CentOS an 8 out of 10.

All of our development is done with Docker on CentOS. In some cases, we also do the deployment for clients on staging and in maybe one or two cases even in production with Docker on CentOS, but mostly it is for development.

Docker on CentOS by itself has great features because the containers concept is already a great use case. Previously, each developer had their own PHP, own Symfony, own database, and then we had some issues with versions. When we deploy to clients, we might have again some such issues. The consistency that Docker on CentOS provides helps our workflow because it avoids developers having issues with versions of applications.

Regarding Symfony, we use many bundles, and not only Docker but also by mainly using things such as Git or Composer, we quite reduce this inconsistency with bundles. Putting everything in Docker helps a lot.

Regarding where I see the biggest gains with Docker on CentOS, it definitely eases the onboarding process because we can more quickly put people to just Git pull and Docker up, and they have a working environment. For issues, except inconsistency issues that we had at some point, we definitely gain here. For deployment, most of our customers have Docker on their environments, and it is easier as well. We have the same environment running everywhere.

Regarding how Docker on CentOS can be improved, I have not thought about this much. If I had to think of one thing that could make my experience with Docker on CentOS even better, I do not have any issues myself. When teams have any issues, I can help them with my experience with it. No specific issues come to my mind.

I have been using Docker on CentOS for about seven or eight years.

Docker on CentOS is quite stable and I have not encountered any issues until now, so for me it is stable.

If my projects or team grew, I think Docker on CentOS would handle more containers or more complex setups easily. I have read and gotten feedback that I did not see any issues regarding scalability. When we talk about scalability, it is not infinite, but for the types of projects we do, I think it is quite scalable.

The customer support for Docker on CentOS is something I have never needed; I always manage by myself.

We did not have any alternate solution before using Docker on CentOS. I discovered Docker about seven or eight years back and really appreciated the idea and have stayed with it.

I choose a ten out of ten for Docker on CentOS because for me it is a tool that helps a lot and I did not have any issues with it. Docker on CentOS is deployed in our organization with no cloud deployment here. Each person has Docker installed on their development environment and we just share the Docker files through Git.

I have no additional thoughts about Docker on CentOS before we wrap up. I just hope that Docker continues as it is and always keeps up to date with new technologies so that we can use it for a few more years.

I have not measured the return on investment for Docker on CentOS, but if intuition counts, I would say ten percent time and energy saved. Regarding fewer employees needed, it does not reduce headcount. It only provides savings and allows us to produce better work.

Regarding my experience with pricing, setup cost, and licensing for Docker on CentOS, as far as I know it is free for small teams, so there are no issues with the pricing. The setup is very smooth as I think I master it or at minimum know it very well. There is no specific licensing on it either.

I did not evaluate other options before choosing Docker on CentOS. I just heard about Docker and tried it because I had already received interesting feedback and never tried any alternative.

Docker on CentOS has impacted our organization positively. I have not quantified how much it has helped us in terms of productivity or gains in avoiding issues, but I would estimate perhaps ten percent improvement. This is not a calculated figure but more of an intuitive assessment.

My advice for others looking into using Docker on CentOS is that if they have not tried it, I would encourage them to go try it. If when trying it they find issues, I would say there is quite a good community around it, so do not hesitate to reach out. Additionally, I would say that the most common AI tools such as ChatGPT and Gemini help a lot if needed. I gave this review a rating of ten out of ten.

My main use case for Docker on CentOS is that I deployed some IBM DB2 database containers.

A specific example of how I use Docker on CentOS with those IBM DB2 database containers is that if you install DB2 on on-prem virtual machines, it takes a long time, but with Docker, it is very fast and easy to recover.

I find that Docker on CentOS is flexible, scalable, and easy to install.

The best features Docker on CentOS offers in my experience are that it is very easy to maintain.

This helps in my day-to-day work because I can watch if my containers are running, if they have any errors or any need for maintenance. I can see them.

Docker on CentOS has positively impacted my organization as it saved us so much time about database installations.

I estimate that if you install databases on generic virtual machines, it takes approximately 30 minutes, but on Docker, it takes one or two minutes.

I think file size management on Docker on CentOS should be improved.

A specific management feature I wish was better or easier to use is that it should maintain its stored files by itself. It should check if there are so many unused files, and Docker should clean them by itself.

I have been using Docker on CentOS for about three years.

Docker on CentOS is quite stable.

Docker on CentOS is quite scalable. You can scale it for small businesses or large environments. It depends on you. Docker allows you to do that.

I haven't needed any customer support on Docker on CentOS.

I haven't previously used a different solution because Docker helps me with all the jobs I have to do.

My advice to others looking into using Docker on CentOS is that they should read carefully the documentation, and they should have done everything right on first installation.

I have seen a return on investment as I save money and time because I can run many DB2 applications in the same virtual machine, so I don't need any extra machines.

My experience with pricing, setup cost, and licensing is that Docker is free to install, so the pricing was acceptable.

Before choosing Docker on CentOS, I did evaluate other options, but they are more expensive and so complicated to maintain.

I don't have any additional thoughts about Docker on CentOS before we wrap up.

Regarding Docker on CentOS's AI capabilities, I didn't use any AI capabilities of Docker on CentOS.

The AI capabilities are something I haven't explored yet.

I give this review a rating of 8.

My main use case for Docker on CentOS is specific to my line of work. If there are any platforms that we have to commission, we prefer to containerize them, which makes them very lightweight and easier to manage. I know that their dependencies are all packaged into the container, so they are not dependent on the bare metal or the host operating systems' dependencies.

I'm leveraging Docker on CentOS in that anything we have to do, we always look at the strategy and ask if it can be containerized. Then we look at containerizing it.

The best features Docker on CentOS offers include the fact that it is OS agnostic and works with its own prerequisites bundled into the container, which makes it flexible to deploy whichever application I'm looking at, so I am no longer held to my system's binaries.

In terms of scalability, I really love how easy it is to spin up another container in order for me to manage workloads, which also makes the management of all workloads easier.

Since adopting Docker on CentOS with a DevOps model, it has positively impacted my organization by making deployments faster, scaling up has become much easier, and the management of services has become more streamlined.

I wish Docker on CentOS's scalability could reach the level of what something like Kubernetes does, as it can scale to the heights of where Kubernetes gets to, and the integrations are much more widespread.

I'm fairly satisfied with Docker on CentOS, but I hope that out of the box, especially with the community editions as well as the enterprise edition, it comes with a graphical user interface.

I've been using Docker on CentOS for roughly a year and a half, and we are still transitioning from monolithic architectures to containerized ones.

Docker on CentOS is stable in my experience, as it has been stable so far.

The scalability of Docker on CentOS in my environment is pretty flexible. As long as I deploy on the right infrastructure, I am able to scale as much as I want.

My advice to others looking into using Docker on CentOS is that they should adopt it, as it's an enjoyable platform to work with. I would rate this product an 8 out of 10.

I have been using Docker on CentOS for five years.

I do not have a main use case for Docker on CentOS, just support tickets regarding the application on Linux.

An example of a support ticket I have handled involves pods that stop responding on an application and operational system impacted by Docker uses regarding CPU or memory resources.

Most of the time, I support Docker on CentOS, not the pods or applications that run inside these pods. I am responsible for the full high availability of servers that support or host Docker. Therefore, I have to ensure that everything is running fine and quickly on the host side.

The best features Docker on CentOS offers, from my perspective as someone responsible for high availability and server health, are the ability to work with containers and pods to run applications and set the best resources for the pods. I can isolate and ensure that everything is running as quickly and efficiently as possible.

Docker on CentOS is the main available solution on the market and is highly used all over the world. It is especially great for hosting applications and also for maintaining and developing these applications in isolated environments. For example, everything that will run in a pod will be handled in any of these pods in the replication and creation of these pods in any of the environments, making the whole infrastructure not only more secure but providing indescribable high availability for applications and customers based on Docker appliances.

Docker on CentOS has positively impacted my organization by helping to change and modify anything regarding applications that have to be available for the customer quickly, and it is also for those that have to be created in the fastest way. For example, Docker can create different specifications for different applications using only one host. It assures that we will not have high costs and will be great especially for the team responsible for the infrastructure as well as for the developers.

Docker on CentOS can be improved by ensuring that we are using the right image available around the world and choosing only the specific needs for applications, the right amount of CPUs and memory, and the isolation of the problems that we can have on production. We can use one host to have different scenarios in a fast and easier way than we would use in the old world or with on-premises virtual machines or physical hosts, which helps us to decrease the cost.

I have been using Docker on CentOS for five years.

I do not see any improvements needed for Docker on CentOS, aside from what I have already mentioned.

My advice for others looking into using Docker on CentOS is to always use a Linux version that has a support team or a community who supports the version regarding the kernel and especially the CVE features regarding vulnerabilities.

I do not have any additional thoughts about Docker on CentOS before we wrap up.

I would rate this review a 7.

My main use case for Docker on CentOS is mostly doing troubleshooting. I get less time to deploy or do any sort of deployment on Docker using CentOS. We have deployed Docker on CentOS, Red Hat, and Ubuntu, but it is basically whenever they go for any testing setup, my team and I are the ones who create the complete Docker environment or even shift the Docker environment from one server to another.

I have been using Docker on CentOS for quite a long time. I have worked in most of the software houses in my previous two or three organizations. We used to do troubleshooting with Docker and sometimes deployment as well.

Docker provides multiple features that include stability and security. Linux itself is a very secure operating system, and because Docker is based on Linux, it has double security. Docker provides stability, security, and modern alterations that we can implement. I am not the person who does testing on Docker, so the DevOps engineer may be able to tell a more exact answer for this question.

Docker on CentOS impacts my organization positively because Docker itself is a good tool to use. It makes life easy. We can prepare Docker quickly in minutes rather than deploying the complete operating system and then libraries. We can deploy Docker and quickly shift applications from one server to another while also making operations easy. It impacts very positively in my organization. The main impact is the reduced cost. Previously, we were using multiple physical servers and cloud machines. When we installed Docker and started working with Docker in the testing environment, it saved our physical machine cost and also the cloud cost.

I should have all the things in my hand to say what needs improvement. I need a specific feature to point out. Because I haven't worked on the features, I cannot say anything on how to improve Docker on CentOS.

I have been using Docker on CentOS for quite a long time.

Docker on CentOS is stable in my experience.

Docker is traditionally considered stable on CentOS-based systems, especially in server environments. Many organizations are running Docker on CentOS, and it is a success of Linux systems that they have made such a useful tool. We can do horizontal scaling with Docker. We can run multiple instances at the same time for an application. Resource usage allows us to divide resources into multiple Docker containers. Easy replication is the best part. We can replicate applications on our own.

I have not been in contact with customer service.

We used to use plain CentOS and Red Hat operating systems. I have not used any other solution than Docker.

I would advise others looking into using Docker on CentOS to give it a try. I cannot answer regarding Docker on CentOS's AI capabilities because I am not the governance person and have no idea about how governance works. Regarding Docker on CentOS's accuracy and reliability of output, accuracy is good for Docker on CentOS and reliability is also good because we have deployed so many applications on Docker on CentOS and they are still working, making it a reliable tool. I would rate this product 7.5 overall.
