Terraform: Support labels for google cloud resources

[JorritSalverda]

According to http://googlecloudplatform.blogspot.nl/2015/10/using-labels-to-organize-Google-Cloud-Platform-resources.html you can now use key/value pairs to label your resources.

It seem to be tags that have key=value format, but if I try that I get the following error, so apparently it's handled differently through the gcloud api.

Reason: invalid, Message: Invalid value for field 'tags.items[0]': 'environment=prod'.  Must be a match of regex '(?:[a-z](?:[-a-z0-9]{0,61}[a-z0-9])?)'

Please add support for this as it will allow us to use this to label our resources for better cost reporting.

Judging from the info in the article it's a replacement for tags, but tags that previously existed are shown as value-less keys, which first led me to believe it used the tags system, but it's separately set with

curl --request POST --header "Authorization: Bearer your-oauth-token" --header 'Content-Type: application/json' --data '{"labels": {"env": "canary"}, "labelFingerprint": "abcdefghij="}' https://www.googleapis.com/compute/alpha/projects/your-project-id/zones/your-zone/instances/your-instance/setLabels

Unfortunately this seems to only be available in the beta API. I'll have to see what might break if we move from v1 to beta.

Have you considered using the metadata instance attribute? It supports key value pairs and is documented here

[JorritSalverda]

I've tested using metadata for it, but it's not what they use below the covers and doesn't unlock the new features. I can wait for the feature to go out of beta though.

I'm asking the SetLabel team internally to see if they have an estimate for when it will leave beta.

1. Any update on when this will reach GA?
2. Will labels be available on all resource types?

Hey!

Any update on this? It would be a brilliant way for us to track costs across different deployments...

Regarding to official documentation of Google Cloud Platform labels are no more in beta

Hi

@lwander , can you remove the upstream label please ?

Labels update on resource need to provide right fingerprint. It would be great to have common functions, that we could use in resource and datasource files.

Thanks !
