#!/usr/bin/env bash
#
# bash completion file for core docker commands
#
# This script provides completion of:
#  - commands and their options
#  - container ids and names
#  - image repos and tags
#  - filepaths
#
# To enable the completions either:
#  - place this file in /etc/bash_completion.d
#  or
#  - copy this file to e.g. ~/.docker-completion.sh and add the line
#    below to your .bashrc after bash completion features are loaded
#    . ~/.docker-completion.sh
#
# Configuration:
#
# For several commands, the amount of completions can be configured by
# setting environment variables.
#
# DOCKER_COMPLETION_SHOW_CONTAINER_IDS
# DOCKER_COMPLETION_SHOW_NETWORK_IDS
# DOCKER_COMPLETION_SHOW_NODE_IDS
# DOCKER_COMPLETION_SHOW_PLUGIN_IDS
# DOCKER_COMPLETION_SHOW_SECRET_IDS
# DOCKER_COMPLETION_SHOW_SERVICE_IDS
#   "no"  - Show names only (default)
#   "yes" - Show names and ids
#
# You can tailor completion for the "events", "history", "inspect", "run",
# "rmi" and "save" commands by settings the following environment
# variables:
#
# DOCKER_COMPLETION_SHOW_IMAGE_IDS
#   "none" - Show names only (default)
#   "non-intermediate" - Show names and ids, but omit intermediate image IDs
#   "all" - Show names and ids, including intermediate image IDs
#
# DOCKER_COMPLETION_SHOW_TAGS
#   "yes" - include tags in completion options (default)
#   "no"  - don't include tags in completion options

#
# Note:
# Currently, the completions will not work if the docker daemon is not
# bound to the default communication port/socket
# If the docker daemon is using a unix socket for communication your user
# must have access to the socket for the completions to function correctly
#
# Note for developers:
# Please arrange options sorted alphabetically by long name with the short
# options immediately following their corresponding long form.
# This order should be applied to lists, alternatives and code blocks.
