+# bash completion file for core docker commands

+#  - commands and their options
+#  - container ids and names
+#  - image repos and tags
+#  - filepaths
+#
+# To enable the completions either:

+#  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.
