# init_grafana_oauth.sh
|
|
#
|
|
# Bootstrap the Google-OAuth secret that kps-grafana mounts as env vars
|
|
# (GF_AUTH_GOOGLE_CLIENT_ID / GF_AUTH_GOOGLE_CLIENT_SECRET) for its native
|
|
# auth.google sign-in flow. Companion to:
|
|
# - deploy/gcp/gke/grafana-google-oidc-secret.example.yaml (envsubst template)
|
|
# - monitoring/kps-values-gke.yaml (Helm overrides for grafana subchart)
|
|
#
|
|
# Auth model:
|
|
# - Anyone in the @knoey.com Workspace can sign in (auth.google.allowed_domains).
|
|
# - chrisfu@knoey.com + ron@knoey.com get Admin (role_attribute_path JMESPath).
|
|
# - Everyone else @knoey.com gets Editor.
|
|
#
|
|
# Usage:
|
|
# ./etc/init_grafana_oauth.sh
|
|
#
|
|
# Env vars (resolved from etc/secrets/* if not set in the shell):
|
|
# GRAFANA_GOOGLE_CLIENT_ID ← from etc/secrets/grafana-google-oidc-client-id
|
|
# GRAFANA_GOOGLE_CLIENT_SECRET ← from etc/secrets/grafana-google-oidc-client-secret
|
|
#
|
|
# Optional:
|
|
# APP_CLUSTER_KUBECONTEXT (default: $KUBECONTEXT then ambient)
|
|
# NAMESPACE (default: monitoring)
|
|
#
|
|
# Pre-reqs:
|
|
# - OAuth 2.0 client created at GCP Console (see the secret template
|
|
# deploy/gcp/gke/grafana-google-oidc-secret.example.yaml for the
|
|
# exact authorized redirect URI + consent screen settings).
|
|
# - Two values saved into etc/secrets/grafana-google-oidc-client-{id,secret}
|
|
# (chmod 0600 each; etc/secrets/ is gitignored except for .keep).
|
|
#
|
|
# After this script runs and the Secret is in place, the next `helm upgrade`
|
|
# (or kubectl-apply of the chart's rendered manifest) of kps-grafana picks
|
|
# up the Secret via `envFromSecret: grafana-google-oidc`. Verify with:
|
|
# kubectl --context=$APP_CLUSTER_KUBECONTEXT -n monitoring exec -it kps-grafana-0 -c grafana -- \
|
|
# env | grep GF_AUTH_GOOGLE_
