# Notes:
# * This script is meant to be loaded from the root of the git repo, which can contain a .env file (with project settings)
# * There is security concerns with loading ssh keys into a container!!! Use at your own risk!
# * This script is for demo only, use at your own risk.
# * Docker for Mac probably will not work with this (sorry I am a Linux user)
# * If you are calling this from Jenkins which is running in a Docker container, good luck - but it is possible!
# * * Hint: The volume mounts for Jenkins in Docker are relative to the host! (A symlink will fix this)
# * * Hint: Add a user to the host that's got a fixed ID and also has the same UID and GID as Jenkins in the container
# * * Hint: The user on the host needs to have the same ssh keys as the user in the container
# * * This is a little tricky to get your head around, but not too hard to implement
# * This also works for development machines (yay consistency!)
# * * I have briefly tested setting IntelliJ IDEA at this as the composer binary. An update worked - which is awesome!
