Google Compute Engine#
The GCE datasource gets its data from the internal compute metadata server.
Metadata can be queried at the URL
http://metadata.google.internal/computeMetadata/v1/
from within an instance. For more information see the GCE metadata docs.
Currently, the default project and instance level metadata keys
project/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 metadata 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 metadata service.
Default: 1
