This assumes you have installed Docker on Linux, Docker is running, and that you have created a container. The docker start command is used to start a container. In this example, the container named my-container will be started.
docker start my-container
docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES d937372c09ab9 b939aa938add9913 "/docker-entrypoin..." 6 minutes ago Created my-container
The -a or --attach option can be used to print stdout and stderr to the console.
docker start --attach my-container
