Docker itself is a commercial solution that is offered by Docker, Inc.
This happens by using external and often third-party solutions such as Marathon, SWARM, Kubernetes, and OpenShift. If you are running multiple containers and as your business starts to depend more and more on containers, you may need to implement Orchestration also.But if you need to run a lot of containers within your own datacenter, you can use Docker datacenter instead. The easiest solution is to use Docker hub, which is all online. And the way how you want to deal with it really depends on the level of scalability that is required in your environments. Image storage is very important in the Docker environment.Docker hub, Docker registry, and Docker datacenter can be used for image storage The core of Docker is Docker image. Docker images are built upon immutable file system images.You use docker push, docker pull, docker commit which closely looks like GIT commands that you are using to download something from GIT, to work with it, to upload something to GIT, and to commit changes if you want to. The way how you work with Docker closely resembles to GIT.Well, in Docker all applications and dependencies are packaged in one single binary, which is the container.Let us understand some more about these container solution Mesos, that is coming from the Apache Foundation.Kubernetes, which is based on Google technology.Now in this article I will share the steps to install docker on CentOS 7 or RHEL 7 Linux and to configure thin provisioning storage for Docker, Now Docker is one of the most common container solution, but it's not the only container solution. In my last article I shared the steps to configure or build ceph storage cluster in Openstack.
