This adds context to all the relevant cloud provider interface signatures.
Callers of those APIs are currently satisfied using context.TODO().
There will be follow on PRs to push the context through the stack.
For an idea of the full scope of this change please look at PR #58532.
Adding an implementation of GetZoneByProviderID & GetZoneByNodeName for
GCE.
This is related to ticket 50926.
This was tested as part of the ongoing separate GCE cloud provider work.
Added unit test.
Fix for wojtek-t (borrowed from FengyunPan)
- Adds AddAliasToInstance() to the GCE cloud provider.
- Adds field "secondary-range-name" to the gce.conf configuration file.
```release-note
NONE
```
Implements #25145
This modification in gce.firewallObject() will return error when trying
to create or update firewall rule if no node tag can be found. Also add
unit test for this modification.
Instead of just rate limits to operation polling, send all API calls
through a rate limited RoundTripper.
This isn't a perfect solution, since the QPS is obviously getting
split between different controllers, etc., but it's also spread across
different APIs, which, in practice, rate limit differently.
Fixes#26119 (hopefully)
We adapt the existing code to work across all zones in a region.
We require a feature-flag to enable Ubernetes-Lite
Reasons:
* There are some behavioural changes if users create volumes with
the same name in two zones.
* We don't want to make one API call per zone if we're not running
Ubernetes-Lite.
* Ubernetes-Lite is still experimental.
There isn't a parallel flag implemented for AWS, because at the moment
there would be no behaviour changes from this.
Previously we'd just tear everything down and recreate it, which makes
for a pretty bad experience because it causes downtime whenever the
service controller restarts and has to make sure everything is in the
desired state.
This adds more code than I'd prefer, but makes it much cleaner and more
organized than it was before, in my opinion. I didn't bother
parallelizing anything because it's complex enough as it is, right now.
It's consistently passing the existing e2es and worked when I tested
manually, but this could definitely use additional e2e tests and/or some
serious refactoring to make real unit tests feasible. I'll follow up
with one or two e2e tests that make sense (updating an LB or killing the
controller manager, perhaps).
