Add an extra flavor to your ZSH prompt, displaying the machine's name (if isn't default) and status of different application containers.

dev_test the machine's name

Download the plugin file docker-compose.plugin.zsh and move it to ~/.oh-my-zsh/plugins/docker-compose/docker-compose.plugin.zsh. Then, add the given plugin in your plugins list in the .zshrc file:

plugins=(git docker docker-compose)

Then, update the shell prompt of your theme. The default theme is robbyrussell so you can update the PROMPT variable in the file ~/.oh-my-zsh/themes/robbyrussell.zsh-theme.

You have to add the $(dock_status)% expression like in the following example:

PROMPT='${ret_status}%{$fg_bold[green]%}%p %{$fg[cyan]%}%c %{$fg_bold[blue]%}$(git_prompt_info)%{$fg_bold[blue]%} %$(dock_status) % %{$reset_color%}'
