Enable kubectl Autocompletion - Tanzu Community Edition

Make sure that you have the bash-completion package installed. If not, you can install it with the following command:

sudo apt-get install -y bash-completion

After that, generate the required kubectl completion rules with the kubectl completion bash command, and then store the rules in your .bashrc file. You can use the following command to do that:

echo "source <(kubectl completion bash)" >> ~/.bashrc

Note: Make sure to run this only once so that you don’t get duplicated rules.

After that, use the source command to activate the new rules:

source ~/.bashrc

Finally, if you now run kubectl get no[TAB] it will be autocompleted.

To make kubectl work for your non-root user, run these commands:

mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
