Docker on centos has reduced costs and now supports reliable client performance testing
What is our primary use case?
My main use case for Docker on CentOS is to provide infrastructure-related support for one of my clients who has their own environment, along with performance testing tools, so we set up Docker on their CentOS servers.
A specific example of how I use Docker on CentOS for performance testing or insulated support is when the client needs to test their application on their environment, so we install the CentOS server with our product image, spin up the container, and test a few use cases.
Regarding my main use case for Docker on CentOS, I face challenges with Docker sometimes having network-related issues, which require us to restart the Docker daemon, but apart from this, I am not facing any other issues with Docker.
What is most valuable?
The best features Docker on CentOS offers are that it works equally well on CentOS as it does on Ubuntu or RHEL, though for one or two specific use cases, we set up Docker on the CentOS environment for our client only.
The compatibility of Docker on CentOS is really smooth, and I have not faced any kind of issue.
Docker on CentOS has positively impacted my organization because I manage the client's environment, and since CentOS is a free version for RHEL servers, they use it for cost criteria, and Docker works smoothly on CentOS.
What needs improvement?
I cannot provide specific outcomes or metrics related to efficiency, cost savings, or performance improvements since using Docker on CentOS in the client environments due to limited access, but I believe they use CentOS for Docker setup for cost-saving, and Docker is stable as an OS for RHEL freeware.
I am not facing any performance or compatibility issues on Docker on CentOS that need improvement.
Docker sometimes has some network-related issues, such as the host network not working, so we switch to a different type of network, and regarding CentOS, we are not using any support since it is freeware, relying only on documentation which serves as our support.
I am not finding anything that Docker on CentOS needs to improve because its documentation covers everything that works as expected.
For how long have I used the solution?
I have been using Docker on CentOS for around four years.
What do I think about the stability of the solution?
Docker on CentOS is stable.
What do I think about the scalability of the solution?
The scalability of Docker on CentOS depends on the hardware; if you have good hardware, you can scale Docker on CentOS as required.
How are customer service and support?
I have not used the support for Docker and CentOS since both are free resources, and I do not believe we need support for this.
Which solution did I use previously and why did I switch?
Before choosing Docker on CentOS, I evaluated other options such as
Ubuntu, as I have used it for our environment, but Docker on CentOS was chosen for the client requirement.
How was the initial setup?
My experience with pricing, setup cost, and licensing for Docker on CentOS is very favorable as CentOS is free of cost and does not require a purchase license, and the same applies to Docker without needing any specific license, but we do need manpower knowledgeable in Docker on CentOS for installation.
What about the implementation team?
We use
AWS as our cloud provider for Docker on CentOS.
What was our ROI?
I have seen some money saved because when someone requires a RHEL-based OS with Docker, CentOS is the best choice due to being freeware, making it easy to set up on that machine.
What's my experience with pricing, setup cost, and licensing?
My experience with pricing, setup cost, and licensing for Docker on CentOS is very favorable as CentOS is free of cost and does not require a purchase license, and the same applies to Docker without needing any specific license, but we do need manpower knowledgeable in Docker on CentOS for installation.
Which other solutions did I evaluate?
I am not using any different solution.
What other advice do I have?
My advice for others looking into using Docker on CentOS is that if your client or company requires an RHEL-based environment and needs Docker, you can set up Docker on CentOS servers easily for testing, and if a subscription-related task is needed, then consider switching to an RHEL subscription.
I do not have any additional thoughts about Docker on CentOS. My overall review rating for Docker on CentOS is ten out of ten.
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?
experience of using docker on centos
What do you like best about the product?
virtualization or containerization was one of the important thing now a days everyone focusing and docker was very useful to create development environment for our projects
What do you dislike about the product?
docker image size optimization related information is very less and sometime consumes lot of space in docker registery
What problems is the product solving and how is that benefiting you?
Docker integrates well with CI/CD tools, enabling automated builds, tests, and deployments. On CentOS 8, this makes it easier to implement robust DevOps practices.
