TAB does not automatically complete docker commands solution

Author:Tobin Harding


Pressing tab key does not automatically complete
docker commands or container names.


Install/configure BASH completion (or your shell of choice).

On Debian GNU/Linux this can be achieved with the following linux command

# apt-get install bash-completion

Open a new shell. If completion is still not functioning you may need
to add (or uncomment) the following lines in
/etc/bash.bashrc. Alternatively these lines can be added
to any file that is sourced by your shell (i.e ~/bashrc, ~/bash_profile)

# enable bash completion in interactive shells
if ! shopt -oq posix; then
 if [ -f /usr/share/bash-completion/bash_completion ]; then
   . /usr/share/bash-completion/bash_completion
 elif [ -f /etc/bash_completion ]; then
   . /etc/bash_completion

Debian package installed as above adds file
/etc/bash_completion.d/docker. If you do not have this
file you will need to download it and place it in
/etc/bash_completion directory. You can find this file
online using your favourite search engine and the search termsdocker completion gist
