Google Cloud Platform

Google Cloud Platform

Compute Engine API

For the access to the Compute Engine API it has to be enabled at the Google APIs console.

User Roles

The user for the Google Service Account that has to be created has to have three roles:

  • Compute Admin
  • Service Account User
  • Viewer

Google Service Account

A Google Service Account for the platform has to be created, see Creating and managing service accounts. The result is a JSON file containing the fields

  • type
  • project_id
  • private_key_id
  • private_key
  • client_email
  • client_id
  • auth_uri
  • token_uri
  • auth_provider_x509_cert_url
  • client_x509_cert_url

The private key is BASE64 containing the newlines as non-escaped strings "\n”. So to avoid the resulting troubles the machine controller expects the whole service account encoded in BASE64.

Passing the Google Service Account

The service account will passed in the field serviceAccount of the cloudProviderSpec. If unset the environment variable GOOGLE_SERVICE_ACCOUNT will be taken.
