The GCE datasource gets its data from the internal compute meta-data server. The instance metadata service can be queried at the URLhttp://meta-data.google.internal/computeMetadata/v1/from within an instance. For more information see the GCE metadata docs.

Currently, the default project and instance level meta-data keysproject/attributes/sshKeys and instance/attributes/ssh-keys are merged to provide public-keys.

user-data and user-data-encoding can be provided to cloud-init by setting those custom meta-data keys for an instance.

Configuration¶

The following configuration can be set for the datasource in system configuration (in /etc/cloud/cloud.cfg or/etc/cloud/cloud.cfg.d/).

The settings that may be configured are:

• retries
  The number of retries that should be attempted for a http request. This value is used only after metadata_url is selected.
  Default: 5
• sec_between_retries
  The amount of wait time between retries when crawling the instance metadata service.
  Default: 1

Example¶

An example configuration with the default values is provided below:

datasource: GCE: retries: 5 sec_between_retries: 1
