This distribution of the Docker containers takes place via the Docker Hub. Besides, we can easily pass the Docker containers on to teammates so that everyone pulls together and develops in the same environment. Out of the other benefits, one is the availability of Docker for all major operating systems- Windows, macOS, and Linux. In Docker, these are simply two independent containers that start the respective servers.
Whereas in a normal Virtual Machine or hypervisor we install a complete Guest with the full-blown kernel that means, if we want to separate the web server from the database server, we would have to start two complete virtual machines including the operating system. without asserting extra stress on the system hardware resources. This makes us start multiple containers with different applications such as Apache web server, MySQL, etc. For instance, you want to install and run Ubuntu 20.04 Server virtually but with a very minimalistic approach, I mean only core files that you need to run this server OS because, on Docker, the Containers are going to share the same kernel. The key difference between normal virtual machines we run such as on VirtualBox is that in Docker not every container has to bring a complete operating system. Here we learn how to install the Docker CE platform on AlmaLinux 8 to create containerized virtual machines.
We can build and communicate containers with one another. I have uninstalled docker-ce-20.10.6, clean up /var/lib/docker folder and reinstall with command "yum install docker-ce-20.10.5.īut this isn't installing docker-ce-20.10.5, rather pointing to 20.10.6.Īny idea how can I make 20.10.5 version as default, and remove 20.10.Docker is not a new term, this virtualization platform is popular for its ability to run applications in Containers. However, I want to use docker-ce.20.10.5. Installing docker with Ubuntu 16.04 LTS, Mint 17 and CentOS 7 A brief introduction to virtualization A brief introduction to containers A Brief history of. Previously I had installed docker-ce-20.10.6.
