This Docker blog post will learn how to enable the Docker CLI command autocomplete on Linux.
Command Autocomplete is a time-saver feature that is a must. It saves time and makes us more productive when using Docker CLI.
To get started, we need to install the bash-completion package first. You might already have it installed on your system; however, it might not install by default if you have a new machine. So go ahead and install it.
sudo apt-get install bash-completion
Note: If you use Redhat based Linux, use sudo yum install bash-completion
Next, we need to create a directory called bash_completion.d inside etc. You can create the directory using the following command.
sudo mkdir /etc/bash_completion.d
Now, run the following command, which will download the Autocomplete bash script to handle the autocomplete.
sudo curl https://raw.githubusercontent.com/docker/docker-ce/master/components/cli/contrib/completion/bash/docker -o /etc/bash_completion.d/docker.sh
The final step is to reload the Bash shell, as shown below.
