What is Docker?
Docker is an open source container runtime that allows you to build, run, and manage applications in isolated environments called containers. Sometimes, an application may work properly when it’s developed on a computer but break when moved to a main server due to different settings. Docker solves this by running the application in an isolated environment, called a container. This ensures the app runs exactly the same way, no matter where you put it. Moreover, you will often use Docker on Ubuntu 26.04 to ensure compatibility and easy deployment.
