# bash prompt support for docker-machine
|
|
#
|
|
# This script allows you to see the active machine in your bash prompt.
|
|
#
|
|
# To enable:
|
|
# 1a. Copy this file somewhere and source it in your .bashrc
|
|
# source /some/where/docker-machine-prompt.bash
|
|
# 1b. Alternatively, just copy this file into into /etc/bash_completion.d
|
|
# 2. Change your PS1 to call __docker-machine-ps1 as command-substitution
|
|
# PS1='[\u@\h \W$(__docker_machine_ps1 " [%s]")]\$ '
|
|
#
|
|
# Configuration:
|
|
#
|
|
# DOCKER_MACHINE_PS1_SHOWSTATUS
|
|
# When set, the machine status is indicated in the prompt. This can be slow,
|
|
# so use with care.
|
|
#
|
|
