gce-metadata

Install

$ [sudo] gem install gce-metadata

As ruby library

gce-metadata provides a way to access meta-data and user-data on GCE instance.

GCEMetadata[:instance_id] GCEMetadata['instance_id'] GCEMetadata[:'instance-id'] GCEMetadata['instance-id']

If you want to specify API version, you can get data like this: GCEMetadata['1.0'][:instance_id]

If you can also get it like this: GCEMetadata['1.0']['meta-data'][:instance_id]

For more detail, see also: http://github.com/akm/gce-metadata/blob/master/spec/introduction_spec.rb

As a command

gce-metadata shows various meta-data and user-data $ gce-metadata

For more detail, type $ gce-metadata -h

Dummy YAML

If you want to access meta-data or user-data not on GCE Instance like on it, make one of these files ./config/gce_metadata.yml ./gce_metadata.yml ~/gce_metadata.yml /etc/gce_metadata.yml

Dummy YAML file must be like output of gce-metadata on GCE instance. You can export it on GCE instance like this: $ gce-medatata > gce_metadata.yml $ cp gce_metadata.yml /path/to/dir/for/non/gce/instance

Or if you don't have GCE instance, you can get an example by $ gce-metadata -d
