CLI Autocompletion

Enabling autocompletion for the CLI

Autocompletion for the CLI is supported for bash and zsh. This allows you to press TAB to get access to subcommands and autocomplete the ones you are writing.

For example, after enabling autcompletion, typing dcos clus[TAB] will give you dcos cluster.

You will need to have the dcos executable in your $PATH and use it with a cluster running on DC/OS 1.12 or later.

Autocompletion for the CLI only completes commands that are available (for example, the commands listed when typing dcos and pressing ENTER). If you are not attached to any cluster, only the following commands will complete: auth, cluster, config, help and plugin.

To complete other commands, you will have to be attached to a cluster and added the respective plugins. Completions are available for the CORE CLI plugin and the EE CLI plugin. These plugins offer static and dynamic autocompletion.


If you want to enable autocompletion for the CLI in bash you must install bash-completion.

macOS: brew install bash-completion
Debian/Ubuntu: apt-get install bash-completion

To activate the completions you must add two lines to your .profile:

[ -f /usr/local/etc/bash_completion ] && . /usr/local/etc/bash_completion
eval "$(dcos completion bash)"


If you want to enable autocompletion for the CLI in zsh you will must add the following two lines to your .zshrc:

autoload -Uz bashcompinit && bashcompinit
eval "$(dcos completion zsh)"
