Docker on CentOS Reviews

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.

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 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.

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.

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.

I have been using Docker on CentOS for almost six years or more.

Docker on CentOS is very stable.

Regarding scalability, it just scales depending on your machine configuration.

The customer support for Docker on CentOS is not really needed. Why would someone reach out for customer support for an open-source software that has lots of documentation and community support? No one would reach out to Docker for support for a simple thing.

I have not previously used a different solution. Docker was the first one and it is going to be the last one.

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.

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.

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.

Before choosing Docker on CentOS, I did not evaluate other options. I just chose Docker on CentOS.

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.

I have been using Docker on CentOS for two years.

My main use case for Docker on CentOS is in my CI/CD pipeline.

A specific example of how I use Docker on CentOS in my CI/CD process is that we use it to containerize and deploy applications.

We also use it for machine learning pipelines.

The best features Docker on CentOS offers me are the Docker repository.

What I like most about the Docker repository is that it is easy to access and deploy.

Docker on CentOS has positively impacted my organization by improving our time to market. It helps with our time to market because we use it so fast to deploy applications across our company.

I don't know how Docker on CentOS can be improved, and I don't wish to add more about the needed improvements or anything I wish it could do better.
