Advantages of Docker

Distributing and using software as a Docker image gives you:

• Bundled Dependencies – Docker images contain all their own dependencies, which means you don’t have to do any installation yourself (compared to an application that is just source code or a .deb installer)
• Cross-platform Installation – Docker containers contain their own operating system, so they will run on any platform (even Windows!)
• Easy Distribution – Can be distributed as a single .tar image file, or put on docker hub so it can be docker pull‘d
• Safety – Files in a container can’t access files on the host machine, so users can trust dockerized applications
• Ease-of-Use – Docker containers can always be run using one single docker run command
• Easy Upgrades – Docker containers can be easily swapped out for newer versions, while all persistent data can be retained in a data volume
