You can infer most of that information by looking at the output of docker inspect
.
For example, you can discover the command started inside the container by looking at the Config.Cmd
key. If I run:
$ docker run -v /tmp/data:/data --name sleep -it --rm alpine sleep 600
I can later run:
$ docker inspect --format '{{.Config.Cmd}}' sleep
And get:
{[sleep 600]}
Similarly, the output of docker inspect
will also include information about Docker volumes used in the container:
$ docker inspect --format '{{.Volumes}}' sleep
map[/data:/tmp/data]
You can of course just run docker inspect
without --format
, which will give you a big (100+ lines) chunk of JSON output containing all the available keys, which includes information about port mappings, network configuration, and more.
