Thanks, can you sign the CLA, please? Should only take 5 mins.

One question on the "name" key. Is it guaranteed to always be there? Or should we mark it as optional?

[BeLi4L]

Yes, the "name" field is always there.

See https://cloud.google.com/compute/docs/reference/latest/instances#name

[tsg]

jenkins, test it

I think this also needs to be added to the fields.yml as it is not there yet.

[BeLi4L]

Done ;)

@BeLi4L you will need to run make update in the root folder of the project, it will update docs with your new field.

Also please add a line to CHANGELOG.asciidoc file

Apart from that, LGTM :) thanks for contributing!

[BeLi4L]

Alright, fixed :)
