How to Check Docker Version?

After you have successfully installed Docker, you can check the docker version with the following command:

docker version

The output will be similar to the following:

check the docker version with the docker version command

This docker version command gives you greater detail about the version of Docker engine installed on your system.

It displays version information for both the Docker client and engine. The Docker client is the program you use to interact with Docker through commands like docker run or docker ps. It's often simply referred to as the docker command.

Alternatively, run the following command which only prints the docker version without too many details:

docker --version

System Info Command

For even more detailed information about the Docker server, use the docker system info command.
