When creating a container using the docker run command, the --name option can be used to give the container a specific name. In this example, a container is created using the foo:latest image, and the name of the container will be foo.

docker run --name foo foo:latest

The docker container ls or docker ps -a command can then be used to display the container. Notice the name of the container is foo.

~]# docker container ls
CONTAINER ID   IMAGE       COMMAND                 CREATED        STATUS   PORTS  NAMES
