Sum the number of cores of running VMs in GKE

gcil | grep standard | grep RUNNING | awk '{print $3}' | cut -d'-' -f3 | paste -s -d+ | bc

Add tags to all VMs of an instance Group

gcloud compute instance-groups list-instances <GKE INSTANCE GROUP NAME> --format=json | jq .[].instance | cut -c93- | tr -d "\"" | xargs -d " " gcloud compute instances add-tags --tags=$TAG

Compress and tarball files, and pipe the output into base64 which will get dumped to your terminal.

tar -czf - ./filesyouwant* | base64

Copy only the base64 output characters into your host's clipboard.

This document exists to provide a template for documenting operational information about a service. The goal is to cover all of the bases so a reader can get a general understanding of the service and how to operate it.

The topics listed are a minimal starting point for documenting a service. Some won't be relevant, if so state why. Almost certainly some issues have been missed should be added to the template as they're discovered(<3 PRs).
