Introduction
I want to run gcloud compute instances list command like this:
gcloud list
I couldn't find how to extend gcloud command offisialiy, so I extend gcloud command by to define alias to .bashrc file.
Define wrapper and alias
Define below in your .bashrc file
gcloud-wrapper () {
if [ "$1" = "switch" ]; then
gcloud config set project "$2"
elif [ "$1" = "list" ]; then
if [ "$2" = "instances" ]; then
gcloud compute instances list
elif [ "$2" = "ip" ]; then
gcloud compute instances list --format="table(NAME,EXTERNAL_IP)" --filter="EXTERNAL_IP:*"
fi
elif [ "$1" = "start" -o "$1" = "up" ]; then
gcloud compute instances start $2
elif [ "$1" = "stop" ]; then
gcloud comupte instances stop $2
else
gcloud "$@"
fi
}
alias gcloud="gcloud-wrapper"
You can extend more to add elif [ "$1" = "list" ]; then line.
If sub command not defined, wrapper run original gcloud command, and you also can use original gcloud command.
