# This is useful for GCP App Engine custom runtime builds, because
# you cannot use multiline variables in their app.yaml, so you have to
# build the key into the container and then tell it where it is
# by setting OAUTH2_PROXY_JWT_KEY_FILE=/etc/ssl/private/jwt_signing_key.pem
# in app.yaml instead.
