Docker on CentOS 8

My main use case for Docker on CentOS  is general use to run our Docker  Compose. A specific example of how I use Docker on CentOS  for general use is that I use Docker  Compose to Kubernetes . I usually combine those tools for orchestration containing containers to deploy our applications. At the moment, I do not remember anything else to add about my main use case; I think we use direct Docker Compose or Kubernetes  in general, all combinations.

In my experience, the best features Docker on CentOS offers are typical features such as creating a network, creating volumes, starting containers, and supporting both test and production for deploying.

Out of those features, starting containers stands out as most valuable for my workflow because it is my job.

Docker on CentOS has positively impacted my organization as it permits us to develop and deploy our applications very easily; that is really useful, and we can use Docker from different CentOS  versions.

This ease of development and deployment has benefited my team by saving time, improving collaboration, and ensuring we have similar versions.

I have no additional information on how Docker on CentOS can be improved. At the moment, I have not received additional information regarding anything specific that could be improved with Docker on CentOS.

Generally, I have thoughts on Docker on CentOS's AI capabilities regarding its governance and security. I think there are no strengths or concerns with how Docker on CentOS handles governance and security for AI workloads.

Regarding Docker on CentOS's AI capabilities, I think it has the possibility for improvement in the accuracy and reliability of output.

I have been working in my current field for about five years.

Docker on CentOS is stable.

Docker on CentOS's scalability is good.

The customer support for Docker on CentOS is fine and faster.

Before Docker on CentOS, I used it as a container, but in general, Docker is more full, which is why I switched.

In general, I did not evaluate other options before choosing Docker on CentOS; I started with it.

My advice to others looking into using Docker on CentOS is to try it one time. I find Docker on CentOS to be a solid, reliable combination for containerized workloads, where CentOS  or RHEL-based systems integrate well with Docker for production deployments. Beyond that, my focus these days is more on Kubernetes orchestration, Helm charts, and infrastructure as code, rather than raw Docker on individual hosts. I gave this review an overall rating of 8.

My main use case for Docker on CentOS  is for local development, tests, and creating new server and server test applications, making the integration from staging and the production environments. Some of that work was applied at Johnson & Johnson.

A specific example of how I use Docker on CentOS  in one of those situations is that we create staging development sites using CentOS  as the original VM application and inside of these VMs, we put Docker  and configure the containers inside of it to make the IP configuration easier on CentOS . We can also create a good network interface and network jobs between the different VMs. We used to isolate some databases in Docker  containers in different stages, using CentOS to separate these stages. We can also create some network environments and share folders between the different VMs using CentOS.

Last week, I built a Proxmox server with some VMs using CentOS and integrating not only Docker but also cPanel  configured by me inside of my Proxmox. I created the environment to make the replication of the tenants from different clients automatically using Node.js as a backend and creating automatically with Terraform  and using CentOS as the main image to use in our environment.

The network integration of Docker on CentOS makes my workflow easier because when I create a new tenant in my environment, I just build a VM with this configurator inside of my ecosystem. I integrate the creation of new VMs and the tenants using Terraform , integrating with CentOS, and inside of this CentOS image, I put Docker and containers, which I use to isolate some clients. However, I need to have access from my tenant manager to create the folders and share them. The containers are isolated between the VMs, but the VMs have some access between them to get some configuration from the original Proxmox environment configurator.

I have some Grafana  and Prometheus applied to these servers, and I made some measures about the improvement in file transfer between them, which shows an improvement of 20% from the last Ubuntu  applications. The easier monitoring between the VMs using that shared folder is also a very useful tool.

Docker on CentOS impacts my organization positively because it is a very useful tool to create a strategic environment where we can plan every container with what we need to do between them. CentOS is a great solution to create the background environment and connect my tenants using my tenant evaluator. With this, I can easily create the environment, network isolation, and sharing folders that we need to share between them.

The best features Docker on CentOS offers are the configuration of the network between the VMs and the integration of this network with Docker, which is the easiest thing that we can use with these environments. When we talk about Ubuntu  or other options, sharing this network and sharing the folders between them is a little bit difficult in comparison with CentOS.

Docker on CentOS can be improved by using the Terraform creation, pointing for a smaller CentOS version that we can create to just take exactly what we need to consume in our image. Instead of getting a full version of CentOS, we can take the small version and only install what we need on the server. This can be very useful to make more space for our clients.

I think Docker on CentOS could benefit from images that we can create or have, for example, just a module based on Portainer  or some UI interface to create the containers automatically or create some internal APIs to make it easier to configure this by Terraform.

I have been using Docker on CentOS since 2016.

Docker on CentOS is very stable.

My setup of Docker on CentOS allows for horizontal scalability; I can upgrade memory and processors, and CentOS automatically scales when we make adjustments inside of the VMs. Docker will adapt to these adjustments using the correctness in the Dockerfile.

My customer support is automated by AI; therefore, I don't have specific feedback about support teams related to CentOS.

I have never needed help from support teams; I find the documentation very well formulated and easier to implement.

Before using Docker on CentOS, I used Ubuntu, but the size of the image for Ubuntu was not optimal, making it harder to configure in Terraform. That's why I switched to CentOS.

The setup costs of CentOS include some versions without a cost, but I don't get the enterprise licensing for now, and I'm using the normal open-source licensing for CentOS.

I deploy Docker on CentOS using a private cloud and my own registry.

I have seen a return on investment; I built my own AI agents connected to my Proxmox server, which led to significant improvements in time and money saved, amounting to over 60%.

The setup costs of CentOS include some versions without a cost, but I don't get the enterprise licensing for now, and I'm using the normal open-source licensing for CentOS.

I evaluated other options before choosing Docker on CentOS, including Debian , Ubuntu itself, and FreeDOS. However, CentOS was easier to integrate and more useful when using WHM and cPanel .

Regarding the accuracy and reliability of Docker on CentOS's AI capabilities, I need to train my AI here to configure CentOS and Docker. After training, the application runs well. AI identifies applications and the configuration accurately, and we can create tools that make AI available to consume the CentOS configuration, even though I haven't yet used CentOS integrated with GPUs or AI engines.

My advice for others looking into using Docker on CentOS is to evaluate your infrastructure and do thorough planning before implementation.

The governance and security of Docker on CentOS are very good because we have a lot of tools to maintain and ensure the sustainability of that environment. This is especially true when integrating keys, and we have keys in all Linux systems, but they put the keys in one space that's easier to get. The first access of CentOS not using root is a very secure feature, as we need to make our root environment and create a root user different from the original root, which is a significant security improvement.

I have given Docker on CentOS a rating of 8.

My main use case for Docker on CentOS  is mostly doing troubleshooting. I get less time to deploy or do any sort of deployment on Docker  using CentOS . We have deployed Docker on CentOS , Red Hat, and Ubuntu , but it is basically whenever they go for any testing setup, my team and I are the ones who create the complete Docker  environment or even shift the Docker environment from one server to another.

I have been using Docker on CentOS for quite a long time. I have worked in most of the software houses in my previous two or three organizations. We used to do troubleshooting with Docker and sometimes deployment as well.

Docker provides multiple features that include stability and security. Linux itself is a very secure operating system, and because Docker is based on Linux, it has double security. Docker provides stability, security, and modern alterations that we can implement. I am not the person who does testing on Docker, so the DevOps engineer may be able to tell a more exact answer for this question.

Docker on CentOS impacts my organization positively because Docker itself is a good tool to use. It makes life easy. We can prepare Docker quickly in minutes rather than deploying the complete operating system and then libraries. We can deploy Docker and quickly shift applications from one server to another while also making operations easy. It impacts very positively in my organization. The main impact is the reduced cost. Previously, we were using multiple physical servers and cloud machines. When we installed Docker and started working with Docker in the testing environment, it saved our physical machine cost and also the cloud cost.

I should have all the things in my hand to say what needs improvement. I need a specific feature to point out. Because I haven't worked on the features, I cannot say anything on how to improve Docker on CentOS.

I have been using Docker on CentOS for quite a long time.

Docker on CentOS is stable in my experience.

Docker is traditionally considered stable on CentOS-based systems, especially in server environments. Many organizations are running Docker on CentOS, and it is a success of Linux systems that they have made such a useful tool. We can do horizontal scaling with Docker. We can run multiple instances at the same time for an application. Resource usage allows us to divide resources into multiple Docker containers. Easy replication is the best part. We can replicate applications on our own.

I have not been in contact with customer service.

We used to use plain CentOS  and Red Hat operating systems. I have not used any other solution than Docker.

I would advise others looking into using Docker on CentOS to give it a try. I cannot answer regarding Docker on CentOS's AI capabilities because I am not the governance person and have no idea about how governance works. Regarding Docker on CentOS's accuracy and reliability of output, accuracy is good for Docker on CentOS and reliability is also good because we have deployed so many applications on Docker on CentOS and they are still working, making it a reliable tool. I would rate this product 7.5 overall.
