Slice of a second start-time

[xeor]

I've made a couple of container cli tools.. And I always found that 1 second container-boot-time to be very annoying. I have "fixed" this on my own projects by having a way to start the container in idle-mode.. ie, something like:

if [[ "${1}" == "--idle" ]]; then
  while true; do
    sleep 3600
  done
fi

then.. If the container is running, I can save that second by using docker exec instead of docker run.
Would that be something worth looking into for this project?

Some of the problems:

• Can't mount current pwd

  • Normally, an ansible project is in the same directory, but if the ansible commands detect a changed pwd. They could recreate the container?

• User looses control over what is running?

  • I ended up making the exec option into a helper, that can be controlled with mycommand-helper. Example mycommand-helper ps.. Also, to use this at all, you must first use mycommand-helper start..

Just throwing the idea out there :) Thanks for a great tool!
