What is your primary use case for Docker on CentOS?

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.

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.

My main use case for Docker on CentOS is for a microservice container service with a Kubernetes orchestration cluster service. I create cluster services for databases, for example Postgres, and services for telecommunication companies, such as Kafka service, HAProxy service, and other services within the company. The main use cases for Docker on CentOS are to reduce costs for the company because container services cost significantly less compared to virtualization services.

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.

My main use case for Docker on CentOS involves multipurpose things that are not specific to an application. There is multi-staging build, and there are more considerations, such as PHP, Python, Node, and Java applications, so there are multiple things involved. I am primarily building multi-staging builds for the front-end type of application with Docker on CentOS to optimize the Docker image. This is the basic use case I am using, but apart from this, there are many more things I am utilizing.

My main use case for Docker on CentOS is to deploy Docker containers and build Docker containers. A quick specific example of how I use Docker on CentOS in my day-to-day work is to deploy a container with a specific business application and microservices, create a microservices environment, and create development and production environments. Anything which can be delivered with Docker is included in my main use case for Docker on CentOS.

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.

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.

Docker on CentOS is used in our organization for containerized applications, with multiple applications running according to microservices architecture resulting in many containers. We use Docker on CentOS to host container-based applications and have integrated CI/CD pipelines using this infrastructure. This is our day-to-day routine, and we have multiple environments including dev, QA, and production, all with similar setups that provide environment consistency. We have an application running on Docker on CentOS that provides a local GitHub storage for our organization. We deployed this as a containerized solution for internal use, acting as an internal GitHub repository. Previously, we were using virtual machines and physical servers, but Docker on CentOS made this solution very lightweight, requiring fewer resources to host. We no longer need to spend significant time getting this container up and running, making it fast and lightweight with a standardized development procedure. We have two instances of Git, one for non-production workload and another for production workload. Docker on CentOS helps with CI/CD pipeline integration, as we use Jenkins for CI/CD which is already integrated. Using Docker containers on CentOS significantly speeds up deployment, as containers start instantly, making applications accessible quickly. We also have other applications running on Docker, such as NGINX and Apache server using Docker containers.

All of our development is done with Docker on CentOS. In some cases, we also do the deployment for clients on staging and in maybe one or two cases even in production with Docker on CentOS, but mostly it is for development.

We have servers running operating systems like Ubuntu and CentOS. Regarding Ubuntu, we are interested in LAMP stack, Ubuntu, or Jenkins on hardened Ubuntu, but we are not using LAMP stack. We are using Ubuntu and then MySQL in a different way, but not LAMP stack. For CentOS, Docker is there, but we are using PostgreSQL, not MariaDB. Docker on CentOS is what we are using. It has been about six years since we started using Docker on CentOS. It is running one of our systems hosted there, on our document management system.

My main use case for Docker on CentOS is for running websites and backend services. I use Docker on CentOS for running websites, specifically for APIs and for running NGINX service. I used Docker on CentOS for a microfinance application that had more than 16 services at that time for the backend. The logic was basically on Node.js, and I used all those microservices on Docker on CentOS. Later on, I used the same service on ECS Fargate.

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.

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.
