The load balancer's name is determined by the service's UID. If the
service's UID has changed (presumably due to a delete and recreate),
then we need to recreate the load balancer as well to avoid eventually
leaking the old one.
Re-GET the service object when we process it rather than trusting the
delta. This will make for a lot more service get requests given that we
resync all the services every 5 minutes, but will avoid re-ordering of
updates and continually retrying stale updates, as has been described in
a few other issues and PRs.
Fix the AWS subnet lookup that checks if a subnet is public, which was
missing a few cases:
- Subnets without explicit routing tables, which use the main VPC
routing table.
- Routing tables not tagged with KubernetesCluster. The filter for this
is now removed.
Added selector generation to Job's
strategy.Validate, right before validation.
Can't do in defaulting since UID is not known.
Added a validation to Job to ensure that the generated
labels and selector are correct when generation was requested.
This happens right after generation, but validation is in a better
place to return an error.
Adds "manualSelector" field to batch/v1 Job to control selector generation.
Adds same field to extensions/__internal. Conversion between those two
is automatic.
Adds "autoSelector" field to extensions/v1beta1 Job. Used for storing batch/v1 Jobs
- Default for v1 is to do generation.
- Default for v1beta1 is to not do it.
- In both cases, unset == false == do the default thing.
Release notes:
Added batch/v1 group, which contains just Job, and which is the next
version of extensions/v1beta1 Job.
The changes from the previous version are:
- Users no longer need to ensure labels on their pod template are unique to the enclosing
job (but may add labels as needed for categorization).
- In v1beta1, job.spec.selector was defaulted from pod labels, with the user responsible for uniqueness.
In v1, a unique label is generated and added to the pod template, and used as the selector (other
labels added by user stay on pod template, but need not be used by selector).
- a new field called "manualSelector" field exists to control whether the new behavior is used,
versus a more error-prone but more flexible "manual" (not generated) seletor. Most users
will not need to use this field and should leave it unset.
Users who are creating extensions.Job go objects and then posting them using the go client
will see a change in the default behavior. They need to either stop providing a selector (relying on
selector generation) or else specify "spec.manualSelector" until they are ready to do the former.
Similar to #11543, the local hostname is not guaranteed to be the node
name, as the AWS cloud provider looks up node name using
`private-dns-name`. This value can be different such as when using a
private hosted zone.
The previous code uses GetHostName(), which fails in this case. Instead,
pass in an empty string so the aws cloud provider will use the cached
self instance to find the instance id.

Like everything else AWS, we differentiate between k8s-owned security
groups and k8s-not-owned security groups using tags.
When we are setting up the ingress rule for ELBs, pick the security
group that is tagged over any others.
We continue to tolerate a single security group being untagged, but
having multiple security groups without tagging is now an error, as it
leads to undefined behaviour.
We also log at startup if the cluster tag is not defined.
