kube-controller-manager: Add configure-cloud-routes option

This allows kube-controller-manager to allocate CIDRs to nodes (with
allocate-node-cidrs=true), but will not try to configure them on the
cloud provider, even if the cloud provider supports Routes.

The default is configure-cloud-routes=true, and it will only try to
configure routes if allocate-node-cidrs is also configured, so the
default behaviour is unchanged.

This is useful because on AWS the cloud provider configures routes by
setting up VPC routing table entries, but there is a limit of 50
entries.  So setting configure-cloud-routes on AWS would allow us to
continue to allocate node CIDRs as today, but replace the VPC
route-table mechanism with something not limited to 50 nodes.

We can't just turn off the cloud-provider entirely because it also
controls other things - node discovery, load balancer creation etc.

Refactor persistent volume controller

Here is complete persistent controller as designed in https://github.com/pmorie/pv-haxxz/blob/master/controller.go

It's feature complete and compatible with current binder/recycler/provisioner. No new features, it *should* be much more stable and predictable.

Testing
--
The unit test framework is quite complicated, still it was necessary to reach reasonable coverage (78% in `persistentvolume_controller.go`). The untested part are error cases, which are quite hard to test in reasonable way - sure, I can inject a VersionConflictError on any object update and check the error bubbles up to appropriate places, but the real test would be to run `syncClaim`/`syncVolume` again and check it recovers appropriately from the error in the next periodic sync. That's the hard part.

Organization
---
The PR starts with `rm -rf kubernetes/pkg/controller/persistentvolume`. I find it easier to read when I see only the new controller without old pieces scattered around.
[`types.go` from the old controller is reused to speed up matching a bit, the code looks solid and has 95% unit test coverage].

I tried to split the PR into smaller patches, let me know what you think.

~~TODO~~

* ~~Missing: provisioning, recycling~~.
* ~~Fix integration tests~~
* ~~Fix e2e tests~~

controller actually needs to use from the client, it should
use separate Namespacers for each of its needs (Scales, HPAs,
and Events).

Allocating CIDRs for Pods works without a cloud provider.
 2015-07-27 17:20:44 -07:00
Kelsey Hightower 93a374512e Allocating CIDRs for Pods works without a cloud provider. 
Currently setting the `--allocate-node-cidrs` flag to true with an
empty cloud provider causes the kube-controller-manager to crash during
startup.

Fix the issue by checking for an empty cloud provider before setting
up route management on the cloud provider. This change introduces a
change in behavior. The kube-controller-manager now supports allocating
pod CIDRs without a cloud provider. This means users must manage routes
through some other mechanism.

The controller manager logs a warning if `--allocate-node-cidrs` is set,
but not a cloud provider:

```
I0725 17:10:41.587888   43185 plugins.go:70] No cloud provider specified.

Fixes #11866
 2015-07-27 16:13:19 -07:00
Alex Robinson 60611c253e Add a resync period for services in the service controller. 
This should ensure all load balancers get deleted even if a reordering of
watch events causes us to strand one after its service has been deleted,
because the sync will notice that the service controller's cache has a
service in it that no longer exists in the apiserver.

It could still leak in the case that the controller manager is killed
between when it leaks something and the sync runs, but this should
improve things.
