Containerization has supported short-term web prototypes but now presents serious security risks
What is our primary use case?
What is most valuable?
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.
What needs improvement?
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.
For how long have I used the solution?
I have been using Docker on CentOS for a few months.
What do I think about the stability of the solution?
In my experience, Docker on CentOS is not stable anymore because it is not actively being maintained.
What do I think about the scalability of the solution?
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.
How are customer service and support?
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.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
I previously used Debian with Docker, which is actively maintained, and I was reading some old documentation recommending CentOS when I started using it.
How was the initial setup?
I did not purchase Docker on CentOS through the AWS Marketplace, but rather through the EC2 section of the AWS console.
What was our ROI?
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.
What's my experience with pricing, setup cost, and licensing?
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.
Which other solutions did I evaluate?
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.
What other advice do I have?
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.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)
Containerization has transformed how I run microservices for high-speed web and API workloads
What is our primary use case?
My main use case for Docker on CentOS is for running websites and backend services. I use Docker on CentOS for running websites, specifically for APIs and for running NGINX service.
I used Docker on CentOS for a microfinance application that had more than 16 services at that time for the backend. The logic was basically on Node.js, and I used all those microservices on Docker on CentOS. Later on, I used the same service on ECS Fargate.
What is most valuable?
The best features Docker on CentOS offers include its lightweight containers and fast startup. Whenever there was a scale-out required for the APIs, it was immediate, less than 10 seconds to boot up, which was very helpful for the microfinance services.
The fast startup and lightweight containers of Docker on CentOS were very helpful because earlier when we used to have these APIs running on the EC2 instances, many instances were required for those services, even though the code was very small. We had to use many EC2 instances instead of using microservices or micro containers like Docker. When we moved to Docker, the scale-out was very fast and very helpful for the business. The boot time with Docker was very less compared to the EC2 instances because running on the EC2 instances required more boot time for the OS, and there was a long delay due to the script execution for a few seconds.
Docker on CentOS has positively impacted my organization as it helped us grow the business, and the customer was very happy with the services, thus revolutionizing the business.
What needs improvement?
Docker on CentOS can be improved by being in sync with the OS updates. The OS is already very compatible with Docker, but it can enhance functionality similar to Kubernetes regarding container orchestration, allowing it to compete with other tools.
The metrics of the containers in Docker on CentOS can also be improved, along with the monitoring part which needs enhancement.
For how long have I used the solution?
I have been using Docker on CentOS for the last four years.
What other advice do I have?
I would advise others looking into using Docker on CentOS that rather than using their services directly on the EC2 instances which costs higher and take more time to boot up, they should go with Docker containers, which are very fast, easy to deploy, and manage, allowing many services to run on the same EC2 instance without dependencies. If a service needs Node.js version 7 and another needs Node.js version 10, there might be conflicts when running directly on EC2 instances, but with Docker containers, these issues do not arise. Moving to microservices like Docker is the best choice rather than directly installing on the EC2 instances. I have covered all the important areas regarding Docker on CentOS. My overall rating for Docker on CentOS is 9 out of 10.
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Containerization has streamlined deployments and now requires clearer lifecycle and orchestration
What is our primary use case?
We use Docker on CentOS to build, package, and run containerized applications on on-premises and VM-based Linux servers. It is primarily used by our DevOps and platform teams, supporting multiple applications across environments. These teams manage container infrastructure and CI/CD pipelines as their major responsibility.
What is most valuable?
The best features Docker on CentOS offers are container isolation, image-based packaging, and portability across different environments.
Portability has made the biggest difference for our team. Since we can containerize and port our applications across different environments easily, it has made our workflow significantly smoother.
These features of Docker on CentOS simplified our application deployment lifecycle and reduced environment inconsistencies that we experienced before implementing it.
We can see faster deployments and reduced environment-related issues since adopting Docker on CentOS. It has truly simplified the application packaging and release process.
What needs improvement?
Docker on CentOS needs native orchestration and lifecycle management, which are currently limited. Teams eventually need Kubernetes or similar platforms at scale to manage containerization effectively. Additionally, better long-term OS lifecycle clarity would be beneficial. CentOS deprecation introduces uncertainty for long-lived environments, so improved long-term OS lifecycle clarity would be helpful overall.
Docker on CentOS is solid for legacy or existing environments, but new deployments should consider newer distributions and Kubernetes-native runtimes to align better with the current container ecosystem direction.
For how long have I used the solution?
We have been using Docker on CentOS for multiple years in production environments.
What do I think about the stability of the solution?
Docker on CentOS has been stable, performant, and well-suited for enterprise Linux environments. However, CentOS lifecycle changes and the industry shift towards Kubernetes and containerd reduce its long-term strategic relevance.
What other advice do I have?
CentOS provides a stable, enterprise-grade OS that is well-aligned with Docker workloads, which is how we use it with our applications. We purchased Docker on CentOS through the AWS Marketplace. I would rate Docker on CentOS overall at seven out of ten.
Containerization has accelerated our CI/CD pipelines and improves time to market
What is our primary use case?
I have been using Docker on CentOS for two years.
My main use case for Docker on CentOS is in my CI/CD pipeline.

My experience with pricing, setup cost, and licensing is that it is good enough.
Which other solutions did I evaluate?
Before choosing Docker on CentOS, I did not evaluate other options.
What other advice do I have?
My advice to others looking into using Docker on CentOS is to try it and use it. I would rate this review as a 9.
Have managed basic deployment tasks and experienced improved service flexibility through containerized environments
What is our primary use case?
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.
What is most valuable?
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.
What needs improvement?
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.
What do I think about the stability of the solution?
Docker on CentOS is quite stable. I would rate it 8 or 9 out of 10.
How are customer service and support?
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.
How would you rate customer service and support?
Positive
How was the initial setup?
The initial setup of Docker on CentOS is not too difficult. We can accomplish it very generally.
What's my experience with pricing, setup cost, and licensing?
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.
What other advice do I have?
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.

Docker on centos pros and cons
What do you like best about the product?
Automating deployment and security as containers in docker are isolated from each other. CentOS handles the docker process very efficiently. Because docker is portable, we can deploy the application in both cloud and on-prime servers, and the containers run smoothly. We can use many containers with different applications to save money.
What do you dislike about the product?
Centos is no longer receiving security updates, which means it will be less safe than it could be.
What problems is the product solving and how is that benefiting you?
Docker's support for both on-premises and AWS cloud environments makes it easy to deploy applications hybridly
Reliable image for your applications, but
What do you like best about the product?
I've been using centos since its version 4 and never dissapoints. So no complains about its performance or the way it works,
What do you dislike about the product?
The direction that Redhat took with Centos development. We don't like that as application developers
