Instructions for installing Docker on some Linux distributions Moreover, when there is a problem with the operating system, instead of installing and reconfiguring the application, users only need to reinstall the operating system, copy the container again. When the container is active, users can move it from one computer to another and between different operating systems easily.ĭocker is a containerized utility that has become very popular, simplifying such tasks. Instead of relying on the operating system to provide what the application needs, all dependencies are bundled in the container itself. Each distribution will be different and you must make adjustments so that the utilities are available in each distribution.Ĭontainerization process makes development easier and can be deployed anywhere. When the program you create works in Ubuntu, making it work in Arch Linux, Debian and other distributions is not as simple as you think. If you are a Linux application developer, you will quickly realize just how difficult it is to make the application available to all Linux distributions.
