Docker on CentOS 8

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.
