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.

My main use case for Docker on CentOS is that we have a whole Kubernetes cluster running, and Docker is a part of Kubernetes, so we just use it. When I want to run a container, I use Docker on CentOS system.

A quick specific example of how I use Docker on CentOS in my work is that initially we had Docker Compose. When we didn't have a Kubernetes system, we were using a Docker Compose YAML file through which we deployed all the Docker containers on our CentOS system. We created a Dockerfile for our application, and then we used databases such as Redis, MySQL, and other tools which were running as a Docker container, and we deployed it in our system.

Regarding my main use case or any other ways I use Docker on CentOS, the main use case is the deployment itself. We use Docker to deploy our application as well as other dependent resources.

The best features Docker on CentOS offers, and what I loved the most, is that we can build a single Dockerfile and build an image for it and then share it with anyone in our team or anywhere, to the customer or anyone who wants to run that application. They just need to have Docker installed on their system and they can easily run it.

Using Docker on CentOS helps my team and makes our workflow smoother because we don't need to worry about the way we ship, the way we share the images, or share the product itself. We have Docker; we can write a simple Dockerfile for the application, and then we can easily share it with anyone we want to, so I think that's the best part.

Docker on CentOS has positively impacted my organization as it made our workflow quite easier. Initially, when we didn't have the Kubernetes system and used to run our product directly on a system, when Docker came along, it really simplified everything.

Docker on CentOS made my workflow easier since the deployment was quite fast after switching to it. We don't have to build everything every time we want to run; we have a Dockerfile, we just build a binary of our application. We use Golang, so we build a single binary and then just build the Docker on CentOS image for the application and we are good to go.

Regarding how Docker on CentOS can be improved, I wouldn't say there are any major issues. The compatibility is quite good. Docker can be easily run on the CentOS system. We just need a yum command to install Docker, and after that, it's quite the same as every other application that we have, so overall it's good.

I think there are sometimes issues with CentOS systems as such regarding Docker; it misbehaves sometimes. Most of the time, I would say 99.9% of the time it works. There are some scenarios where sometimes we might face some issues on CentOS systems.

In terms of accuracy and reliability of output from Docker on CentOS's AI capabilities, I wouldn't say it is 100% accurate. Sometimes it does hallucinate, but overall it's good.

I have been using Docker on CentOS for four years since the start of my career.

Docker on CentOS's stability is quite good. Overall, it's quite usable and there's nothing to worry about.

Regarding Docker on CentOS's scalability, it's quite easy to deploy and scale it as well.

Customer support for Docker on CentOS is good. Whenever we are stuck, we get customer support easily. On a scale of 1 to 10, I think overall customer support for Docker on CentOS is good.

I did not previously use a different solution before Docker on CentOS. I think we started with Docker itself; earlier we were using just a bare minimum application to deploy it, but eventually, when we got to know Docker, we felt it's quite good to use, so we started using it.

My experience with pricing, setup cost, and licensing for Docker on CentOS is that it's quite easy to set up, so I think it was not that tedious.

I have seen a return on investment with Docker on CentOS; time is the major factor here. In our case, it was quite easy to use it and deploy it, so that is one of the main things that we observed.

My experience with pricing, setup cost, and licensing for Docker on CentOS is that it's quite easy to set up, so I think it was not that tedious.

Before choosing Docker on CentOS, I did not evaluate other options. In our case, we just went with Docker because we felt it's quite easy and it's something that we need to use.

It's quite easy to learn Docker on CentOS. I think the learning curve is not steep; it's quite easy. You don't have to worry much. You just need a Docker command, and then you just need to know the simple commands and you can easily run it.

I would rate Docker on CentOS as a 10 out of 10 because it has really made our workflow quite easy to deploy on a system. I chose 10 out of 10 for Docker on CentOS because I think the ease of deployment and ease of using it is unmatched. We don't have any significant learning curve; we just need to know how exactly a Dockerfile works and a couple of commands for Docker and you're good to go. You can easily build your images and then deploy it anywhere you want to.

Regarding Docker on CentOS's AI capabilities, I would say it's good. I see that due to the AI feature, if we are getting stuck or need some commands or anything, we are able to just get it through the AI, so that is good. Docker on CentOS is deployed in our organization on a public cloud.

My advice to others looking into using Docker on CentOS is to use it because it will really make your workflow easier and quite fast. In terms of business relationship with this vendor, we are just a customer; we don't have any other relationship. My overall review rating for Docker on CentOS is 10 out of 10.

My main use case for Docker on CentOS is hosting web applications, working with microservices, setting up HAProxy load balancers, building application images, creating containerized images, and deploying multi-tier applications.

A specific example of a web application I have deployed using Docker on CentOS is NGINX, along with Apache HTTPD, while also working on some Node.js and Python-based applications inside containers.

The best features Docker on CentOS offers include very lightweight containers, fast deployments, portability, isolation, and image-based deployments.

The isolation feature helps my team as each container runs separately whenever we deploy any web-based application, ensuring that if one application crashes, others are not directly affected.

Docker on CentOS has positively impacted our organization by providing faster application deployment, better resource utilization, and easier scaling.

Faster deployment with Docker on CentOS saves us time, as traditional methods for building microservice-based servers take about thirty minutes to one hour, while using Docker on CentOS allows us to spin up containers within one second, avoiding dependency conflicts. Containers use fewer resources than virtual machines and traditional virtualization technology.

Docker on CentOS can be improved in areas such as container security and monitoring complexity, which need to be addressed from the CentOS end.

Regarding improvements related to security, containers share the host kernels, where improper configuration can create risks. In monitoring complexity, large container environments require logging, monitoring, and orchestration, while currently, only Docker on CentOS logs provide some metrics but not in a very well-structured way.

The reason I give it a nine is due to weak points like needing expertise in production security, where large deployments require proper image scanning, role-based access control, runtime security, and orchestration. While Docker on CentOS has orchestration like Docker Swarm, it falls short in image scanning and RBAC, making it insufficient to scale properly in a container environment without a well-matured orchestration.

I have been using Docker on CentOS for the last five years.

Docker on CentOS is very stable in my experience.

Scalability-wise, Docker on CentOS is very good, as it spins up new microservices containers within a second and allows us to create multi-tier applications in a very limited time.

The customer support for Docker on CentOS has been good, and I have had to reach out to them.

I have not used a different solution before Docker on CentOS, as we are only using Docker on CentOS as our container engine and CentOS as our base operating system.

Before choosing Docker on CentOS, I did not evaluate other options; we have been using Docker on CentOS from scratch as our container engine.

My advice to others looking into using Docker on CentOS is that if they are interested in launching containerization-based technology, they should evaluate the skills with Docker on CentOS containers, play with containers, create container images, run containers in a very limited time, and test microservice-based applications using containerization technology, which are some of the main features of Docker on CentOS. I give Docker on CentOS a rating of nine out of ten.

My main use case for Docker on CentOS is to deploy our web app only. Docker is the centralized space where we can collate all our codes to run in a centralized environment. We have an embedded app which is hosted on the website, where we can use Docker to deploy our app. It acts as a mini virtual environment for our apps to run and compile on the server.

A specific example of a web app I have deployed using Docker on CentOS is a web app for a car-related company. They wanted to analyze their sales for a particular quarter, so we created a React-based web app where we used the Docker environment for compiling our Django app, which serves as the middleware server.

We have deployed a couple of apps using Docker on CentOS. We mainly use Docker for our Python-based web apps to be deployed, which act as the middleware server. We have also used a MongoDB-based app in Docker, and it is quite helpful.

In my opinion, one of the best features Docker on CentOS offers is the ability to define all the library versions and Python versions that are compatible with my project. I do not know of any other CentOS solutions that enable us to use these features on their servers or websites. However, in Docker, I can use a dedicated Python version and dedicated libraries that I need for my app, which is very helpful for ensuring my app works seamlessly on the website.

Having control over library and Python versions helps my workflow because we started this development a couple of months ago. At that time, we used the latest Python version 3.9, but now Python 3.14 has come out. The libraries compatible with Python 3.9 are specific to that version, and there have been syntactical changes in Python 3.14. I want to deploy my app specifically in the 3.9 Python version, which is why I use Docker to deploy my app. It is very helpful because it compiles all my libraries using the Python 3.9 version only.

In terms of scalability, Docker on CentOS is very helpful because we are currently using the Linux OS. However, if we want to use Windows or any other operating system that is specific to our particular app, we can do that in Docker. That is an added advantage. We can also create multiple Dockers to communicate with each other. Even though Kubernetes is a separate topic, Docker's capabilities are quite helpful.

One improvement I would like to see in Docker on CentOS is how sometimes when I try to install the recommend.sh file, it fails with timeout errors on the server side. It would be better if those kinds of issues are improved within Docker. Although Docker has excellent community forums, where we can analyze and search for any doubts, resolving the timeout error would enhance my experience and make it easier to use across any web apps. That is my suggestion.

Docker on CentOS is already quite good, and it has very good community forums and a helpful website. Other than that, I find Docker on CentOS to be exceptional.

I have been using Docker on CentOS for the past two years.

Docker on CentOS is very stable in my experience.

Docker on CentOS's scalability is impressive, as it handles growth and expansion very well for our apps. It is compatible with all operating systems including Linux and Windows, making it easy to scale, and we can use it for multiple regions as well.

The customer support for Docker on CentOS is excellent, as there are very good community forums. Whenever we run into issues, we can turn to these forums, where we can easily find solutions by pasting the errors we receive. Many tech experts have contributed to the forum, making it easy for us to get help.

We have not used any different solutions before Docker on CentOS; we have been using Docker from the start.

I have seen a return on investment with Docker on CentOS, especially in terms of time saved. Compared to other deployment processes, Docker significantly reduces our deployment time. Previously, it took us about a week to deploy, but now we can deploy our entire app in one or two days.

Regarding pricing, setup cost, and licensing for Docker on CentOS, everything is handled at the on-premises level. My company manages everything, so we do not need to pay any extra fees for that; we pay a total organizational amount and utilize it.

Before choosing Docker on CentOS, we did not evaluate any other options; Docker was our first preference.

Docker on CentOS has positively impacted my organization because, deployment speed-wise, it is similar to other CentOS apps, but Docker is user-friendly. Even a non-coding person can leverage AI's help to write Docker code easily. It helps create working directories and manage any libraries or folders I need, so I can operate in a straightforward, human-friendly manner, making Docker very helpful.

This user-friendliness has impacted my team significantly because we are in an organization that is not tech-dependent. If we need to host a tech-dependent app, we typically have to learn everything from scratch. However, using Docker bypasses the need for extensive technical knowledge. I can create a Docker app without any tech knowledge by utilizing human-readable formats and the help of AI and Google, allowing me to compile my web app on a Django server using Docker. It is extremely beneficial.

I rate Docker on CentOS overall as an eight out of ten. The reason I choose eight out of ten is because, while I would like to give a perfect score, there are some timeout issues and other challenges with Docker. If those could be resolved, that would improve my satisfaction. Besides that, there are great community resources and forums available for Docker that are very helpful, and I do not feel any other changes are needed from Docker's side.

I definitely advise others to go for Docker on CentOS instead of any other options. As I mentioned, it is very user-friendly, requiring no technical knowledge, and anyone can write Docker code in my opinion, so I encourage people to proceed with it.
