Say I have this right now:
docker run -v /root/.ssh:/root/.ssh:ro my_image
and the ENTRYPOINT for the above image is:
ENTRYPOINT ["echo", "foo"]
instead I want to do something like this:
docker run -d --name c my_image # problem: this will likely exit early :( docker cp /root/.ssh c:/root/.ssh docker exec c echo foo
the problem is: how do I keep the container alive so that it waits for me to copy the ssh key into it and then run the
echo foo command?
Maybe I can keep it alive by telling it to wait for stdin? But how exactly?
