What exactly is Docker?
Docker is an open source containerization software that creates switzerland phone number data environments to run an application. Then, you develop, test, and run multiple applications on the same computer.

Unlike virtual machines, each container does not require its own operating system and shares the host kernel. Therefore, the machine workload is much lighter and a single server can run multiple containers at the same time.

For this reason, Docker is very useful for WordPress developers. A WordPress testing environment usually consumes a lot of system resources while Docker will help them create a minimal environment without wasting server space and memory.
