Common Patterns

Bootstrap Secret for CSI Driver

When using CSI Driver, a bootstrap secret may be needed to break the chicken-and-egg cycle:

# Create bootstrap secret from Key Vault
kubectl create secret generic <app>-bootstrap \
  --namespace <namespace> \
  --from-literal=client-secret="$(az keyvault secret show \
    --vault-name <vault> \
    --name <secret-name> \
    --query value -o tsv)"

Ingress Annotations for OAuth2 Proxy

annotations:
  nginx.ingress.kubernetes.io/auth-url: "https://oauth2-proxy.<domain>/oauth2/auth"
  nginx.ingress.kubernetes.io/auth-signin: "https://oauth2-proxy.<domain>/oauth2/start?rd=$scheme://$host$escaped_request_uri"
  nginx.ingress.kubernetes.io/auth-response-headers: "X-Auth-Request-User,X-Auth-Request-Email,X-Auth-Request-Groups"

Testing OAuth Flow

# Get authorization URL
curl -sS -k -D - -o /dev/null "https://<app>/login/<provider>/" 2>&1 | grep -i location

# Verify redirect_uri format
# Should be: redirect_uri=https://<domain>/complete/<provider>/
# NOT: redirect_uri=https,%20https://...
