Google Cloud components not being enabled - docker

Question

I'm trying to get an automatic build going via Travis-CI to google cloud, but when I'm trying to run "gcloud docker any_command", I get the message
ERROR: (gcloud) Invalid choice: 'docker'. Did you mean 'config'?
and when I try to install docker with "gcloud components install docker" I get
You cannot perform this action because the component manager has been
disabled for this installation. If you would like get the latest
version of the Google Cloud SDK, please see our main download page at:
https://developers.google.com/cloud/sdk/
ERROR: (gcloud.components.update) The component manager is disabled for this installation
