Bash aliases for common invocations of `docker-machine`

docker-machine_dot_bash_profile.sh

# ~/.bash_profile

# `docker-machine` is commonly used for controlling a local VM which acts as your 
# Docker host. What occationaly happens is that I have to(*) restart the VM, and 
# subsequently re-assign the DOCKER_* environment variables in each Terminal 
# window I have open. These completion-friendly aliases makes it less of a chore.

alias docker-env-eval='eval "$(docker-machine env default)"'
alias docker-machine-refresh='(docker-machine stop || docker-machine kill) ; docker-machine start; docker-env-eval'

# (*) This is commonly due to one of the folloing reasons:
#  - the host is low on battery which triggers VirtualBox to suspend all running VM:s
#  - `docker-machine stop default` was deliberately invoked, to save power
#  - network reconfiguration events have caused bridging/forwarding to stop working
