Feature

Points

Cloud Functions probably doesn't support cloud_auth.

cloud_auth.ts is used gcloud .It is not available on Cloud Functions.

I responded as follows. Do not define authProvider . Because CloudAuth is executed, it will be an error.

    users: [
      {
        name: env.k8s.clusterFullName,
        user: {
          token: token,
        }
      }
    ]

user.token : Google API Authentication token.
The token is obtained using the Google Auth Library.

async function getToken() {
  let authResult = await auth.getClient({ scopes: 'https://www.googleapis.com/auth/cloud-platform' });
  let accessToken = await authResult.getAccessToken().catch((err) => {
    throw err;
  })
  return accessToken.token
}
