Get the docker launch command for the container

Question

I have a container that I created, but I can’t remember the exact docker run that I used to run it. Is there any way I can get it?

This is not the same as See the full container start / stop command in Docker . I want to know that this is the complete docker command that spawned the container, not the commands inside the container.

You can print most of this information by looking at the output of docker inspect .

For example, you can open a command running inside a 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 run later:

 $ docker inspect --format '{{.Config.Cmd}}' sleep 

And we get:

 {[sleep 600]} 

Similarly, the output of docker inspect will also contain information about the Docker volumes used in the container:

 $ docker inspect --format '{{.Volumes}}' sleep map[/data:/tmp/data] 

Of course, you can simply run docker inspect without --format , which will give you a large (100+ lines) fragment of JSON output containing all the available keys, which includes information about port mappings, network configuration, etc.
