# A script to automate some parts of new certificate deployment.
#
# See http://go/skia-ssl-cert for a longer description and the command you need
# to run before running this script.
#
# This script must be run with breakglass. See http://go/skia-infra-iac-handbook
# for instructions.
#
# This script adds new certs to gcloud, and makes a local change to the
# skia-ingress.yaml file. Applying the change to kubernetes, pushing the change
# in git, and deleting old certs are left as manual steps to allow for manual
# inspection of the change.
