DESCRIPTION
TIP: Consider setting aprojectlien on the project to prevent it from accidental deletion.
EXAMPLES
To create a root CA that supports one layer of subordinates:

To create a root CA that is based on an existing CA:

gcloudprivatecarootscreateprod-root--location=us-west1--pool=my-pool--kms-key-version="projects/my-project-pki/locations/us-west1/keyRings/kr1/cryptoKeys/k1/cryptoKeyVersions/1"--from-ca=source-root
