gcfg is a very small shellscript that utilizes fzf to conveniently switch between gcloud configurations.
It is directly inspired by the Kubernetes namespace switcher kns.
To install gcfg you can just run this command:
curl https://raw.githubusercontent.com/cmeury/gcfg/master/bin/gcfg -o /usr/local/bin/gcfg && chmod +x $_
Then, run gcfg
.
