docker run

Docker runs processes in isolated containers. A container is a process which runs on a host.

The docker run command must specify an IMAGE to derive the container from.

With the docker run [OPTIONS] an operator can add to or override the image defaults set by a developer. And, additionally, operators can override nearly all the defaults set by the Docker runtime itself.

docker run [OPTIONS] IMAGE[:TAG|@DIGEST] [COMMAND] [ARG...]

Option : Detached (-d)

• To start a container in detached mode, you use -d=true or just -d option.
• By design, containers started in detached mode exit when the root process used to run the container exits, unless you also specify the --rm option.
• If you use -d with --rm, the container is removed when it exits or when the daemon exits, whichever happens first.

docker run -d -p 80:80 my_image

Option : Container identification (--name)

docker run --name my-redis -d redis

OptionL: Clean up (--rm)

Docker to automatically clean up the container and remove the file system when the container exits, you can add the --rm flag:

--rm=false: Automatically remove the container when it exits
