Containerization has streamlined deployments and now requires clearer lifecycle and orchestration
What is our primary use case?
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.

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 8: A great tool but struggling due to End-of Life cycle
What do you like best about the product?
- Docker simplifies application deployment and management using containerization, which helps with consistency across platforms in all environments.
- Using the official package manager of Yum it's very easy to install and use Docker on CentOs 8.
- The community has great resources that can solve almost all problems faced during troubleshooting.
- Docker is one of the very critical tools in my tech stack because it helped me with building the Ci/Cd pipeline and having smooth deployment and rollbacks if necessary.
- With additional features like Docker Compose and Docker Swarm it's very easy to use, deploy, and manage multiple services.

What do you dislike about the product?
- One of the biggest downsides of using docker with CentOs 8 is the archived version now because it stopped getting security updates after the end of 2021 which makes it a security threat for production use.
- Docker in itself is a complicated product that can take a while to understand and sometimes can be hard to understand OS-specific issues if occur for a beginner.
- Docker is great in performance but there were specific incidents in the past where I faced performance overhead and it took a while to figure out the issue because it required both docker and CentOs 8 in-depth knowledge to debug.
