"docker pull" is a command used in the Docker platform to download and get the latest version of a Docker image from a Docker registry. It pulls the Docker image from the registry and stores it in the local Docker host, which can be used to create and run Docker containers based on the image. The syntax for the command is:
docker pull [OPTIONS] NAME[:TAG|@DIGEST]
For example, to pull the latest version of the official Ubuntu image, the command would be:
docker pull ubuntu
If you want to specify a specific version of the image, you can add the version number (tag) after the image name, like this:
docker pull ubuntu:20.04
This command will download and store the Ubuntu 20.04 version of the image onto your local Docker host.
