Adding labels to GCE resources

[ro6ert]

I would like to label my gce instances and resources for billing purposes, but the concepts of network tags and billing labels have diverged in GCE and tags no longer suffice. Is there an easy way to add labels (key/value pairs) from the elasticluster start command? If not, I need to code one, and if I have to do that, can I make a pull request so the changes are included into future releases?

I'm afraid there's currently no support in ElastiCluster for setting metadata labels, although that would be a very welcome addition!

If you want to try adding it yourself, you probably would need to:

• Add labels as an optional argument into GoogleCloudProvider.start_instance(), then add the key/value pairs into compute_metadata -- this is the easy part :-)
• Add an appropriate representation for the wanted label key/value pairs to the configuration file schema, ensure it is copied to all nodes
• Optionally, add command-line arguments to override or add labels when starting a cluster, by adding command-line options to the Start class in subcommand.py

Thank you and please feel free to ask questions here if you need help!

I passed the labels argument from the command line to the cluster creator factory and now it seems to be working. There are lots of print line statements and commits that failed to work, but I can put a label in the instances now.

Can you please make a Pull Request? That would make it easier to review and merge.
