Docker on CentOS 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.
