A host UUID was added to the Linode Instance in a client change: linode/linodego#284

Apply this UUID from the CCM to expose the underlying host uniqueness, can improve scheduling and placement decisions for resources deployed on clusters with CCM installed.

is this still required after the linodego update?

[shanduur]

This is the same logic as in the linode-cosi-driver and linode-blockstorage-csi-driver, added there just so we have similar code paths in all 3 components.

maybe a dumb question, but why dont we make a linodeClient.ParseURL which does this logic and sets the base url and version for you. this would move all this logic to the linodego and we could reuse it right?

@lgarber-akamai @zliang-akamai for visibility on my dumb questions

Hi @luthermonson, I think you are right. Let us discuss it and get back to you next week.

Sorry for the late follow-up! I think this is a good idea and I've created a ticket internally to get this implemented ^

looks good - agree with uuid -> host-uuid change.
