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.

My main use case for Docker on CentOS is for a containerization platform, packaging applications with their dependencies for lightweight and portable containers.

A quick, specific example of how I use Docker on CentOS for containerization is that we have dockerized our frontend, backend, and database into containers, and we have hosted them using Docker on CentOS. We have multiple software images for availability and for application uptime, and it is lightweight.

The best features Docker on CentOS offers are its lightweight and fast nature, with containers sharing the OS kernel, making it faster than VMs and providing quick startup time. It also ensures a consistent environment where applications will work on every machine, not just the developer's machine, and offers resource efficiency, such as no full OS per application, allowing me to share my infrastructure with multiple containers and applications. Additionally, it provides easy deployment and scaling.

The most valuable features to me in my daily work are all of the following: lightweight nature, consistent environment, resource efficiency, and easy deployment. We do not need to worry about our source requiring more memory; it is lightweight and fast, and the deployment does not take much time. If we want to scale our infrastructure, we can just create a new Docker image and it will scale, so all of those features are important to us.

Docker on CentOS has positively impacted my organization because we do not need much resource per application, and our deployment time has decreased, allowing us to avoid using more VMs to host our applications. Regarding the decrease in deployment time, I am saving 30 to 40 percent of our time, and before Docker, we had been using 10 to 20 VMs, but after that, it has become half, approximately 10 or 11 VMs.

Docker on CentOS can be improved by addressing security concerns, such as sharing the kernel, which leads to weaker isolation than VMs. Sometimes misconfiguration can happen, such as using ports or other networking issues. Currently, as I have heard, Docker on CentOS is not officially supported, so I am considering whether there are alternatives or not.

I have been using Docker on CentOS for two years.

Docker on CentOS is stable, but as I mentioned, there are some improvements needed, and after that, I hope it will be good.

Docker on CentOS's scalability is good; if we need more resources, we can just spin up a new Docker image, so scalability is good.

I previously used VMs, but they were expensive, and it was an overhead for us to manage, so that is why we switched to Docker on CentOS.

After switching to Docker on CentOS from VMs, I have seen a return on investment, saving 40 to 50 percent of our money as well.

My experience with pricing, setup cost, and licensing is that there is no licensing in Docker on CentOS, and the setup is easy; we just need to create the images for our application, so it is easy.

Before choosing Docker on CentOS, I did not evaluate other options because we had a clear mindset that we wanted to use Docker on CentOS. We saw the public review, so that is why we thought we wanted to use Docker on CentOS only.

My advice to others looking into using Docker on CentOS is that if they want to containerize an application, make their deployment easy, avoid VM management overhead, and save costs, they can use Docker on CentOS. I would rate this product an 8 out of 10.

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.

I have been working in my current field for three years.

Docker on CentOS is stable.

Docker on CentOS's scalability is good enough.

The customer support is good.

I did not previously use a different solution before Docker on CentOS.

I have not seen metrics for a return on investment.

My experience with pricing, setup cost, and licensing is that it is good enough.

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

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.

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.
