What is our primary use case?
My main use case for Docker on CentOS involves running containers, testing applications, and pulling out niche applications, older versions of applications or software, and then using those for testing.
A quick specific example of an application or scenario I have tested using Docker on CentOS is testing an old version of Ruby code inside a Docker container. For instance, a Rails application written on Ruby 2.7, when the Ruby version is now 3.something or four as well, I just pull out the Docker container and then run it.
I have additional insights about my main use case. Testing out older versions of applications and older versions of software is one aspect. Another aspect is running our development server, not a local server, but the development server. Then it goes to staging and production. I run the development server on Docker on CentOS containers.
What is most valuable?
The best features Docker on CentOS offers for me include volume mount, where I can mount a directory inside the container as a volume and then write it inside, and then I get the whole thing on the host as well. If I write it outside on the host, it gets inside. This is a really good feature.
The volume mount helps my workflow and productivity significantly. If I need to test something, I just mount the volume, mount my code as a volume, make changes, it appears inside, test it, and then I am done after testing.
Docker on CentOS has positively impacted my organization by making testing easier. I do not have to install older versions of applications and then make my system or service study. I just pull out a Docker container and then use it. This helps in saving time as well. When I run the whole thing in Docker Compose, that also helps in speeding things up. Once I have Docker Compose created, I just do Docker Compose up, and then everything works. This is mostly time-saving.
What needs improvement?
I believe everything is good, and there is no improvement needed for Docker on CentOS.
Regarding needed improvements, I think compatibility is already compatible with everything that is there. However, documentation could be improved. Documentation could be made more accessible, more readable, and all those things.
For how long have I used the solution?
I have been using Docker on CentOS for almost six years or more.

Which solution did I use previously and why did I switch?
I have not previously used a different solution. Docker was the first one and it is going to be the last one.
How was the initial setup?
My experience with pricing, setup cost, and licensing is that there is no licensing cost required. The setup is just running a few commands that are already recorded or documented. Nothing much is involved.
What was our ROI?
I have not seen a return on investment since you install and use it. What return on investment is needed when using a simple tool? It is just there to use.

Before choosing Docker on CentOS, I did not evaluate other options. I just chose Docker on CentOS.
What other advice do I have?
I would add that those are the features I mentioned by default, so I have no comments on networking, images, or resource management.
My advice for others looking into using Docker on CentOS is just to install and use it. I give this review a rating of 9.
