docker run

[benbro]

It could be useful to have an equivalent to the docker run command
http://docs.docker.io/en/latest/commandline/command/run/
docker_container:run/3 will run a command in a container and gives back the output, possibly warnings and errors too.

Create a container and run a command:
docker_container:run(Cmd, Options)

Run a command in existing container:
docker_container:run(CID, Cmd, Options)

Cmd = binary/string of the command to execute
Options = proplist of options similar to what docker run has.

In addition we could add
{timeout, Timeout} Kill the container if it doesn't respond after Timeout.
{delete, true} Delete the container after executing the command

This could be implemented using:
docker_container:create/1 in case we want to also create a new container.
docker_container:start/2 Start the container
docker_container:wait/1 Wait for the container to exit. Here we can use a timeout too.
docker_container:attach_stream/1 will collect the output.
docker_container:stop/1 or docker_container:kill at the end.

I'm looking to implement this feature later.

Right now you can have this functionality through erlsh:

> erlsh:run([erlsh:fdlink_executable(), "/bin/sh", "-c", "docker run base echo hi"]).
{done,0,<<"hi\n">>}
