The minion server will
- launch the proxy and executor
- relaunch them when they terminate uncleanly
- logrotate their logs.
It is a replacement for a full-blown init process like s6 which is not necessary
in this case.
The basic idea is that in the main mungedocs we run the entirefile and
create an annotated set of lines about that file. All mungers then act
on a struct mungeLines instead of on a bytes array. Making use of the
metadata where appropriete. Helper functions exist to make updating a
'macro block' extremely easy.
OpenShift uses multiple API packages (types are split) which
Kube will also eventually have as we introduce more plugins.
These changes make the generators able to handle importing different
API object packages into a single generator function.
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:
```

```
Fixes#11866
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.
