This commit is the main API piece of KEP-3257 (ClusterTrustBundles).
This commit:
* Adds the certificates.k8s.io/v1alpha1 API group
* Adds the ClusterTrustBundle type.
* Registers the new type in kube-apiserver.
* Implements the type-specfic validation specified for
ClusterTrustBundles:
- spec.pemTrustAnchors must always be non-empty.
- spec.signerName must be either empty or a valid signer name.
- Changing spec.signerName is disallowed.
* Implements the "attest" admission check to restrict actions on
ClusterTrustBundles that include a signer name.
Because it wasn't specified in the KEP, I chose to make attempts to
update the signer name be validation errors, rather than silently
ignored.
I have tested this out by launching these changes in kind and
manipulating ClusterTrustBundle objects in the resulting cluster using
kubectl.
The name "PodScheduling" was unusual because in contrast to most other names,
it was impossible to put an article in front of it. Now PodSchedulingContext is
used instead.
1. Define ContainerResizePolicy and add it to Container struct.
2. Add ResourcesAllocated and Resources fields to ContainerStatus struct.
3. Define ResourcesResizeStatus and add it to PodStatus struct.
4. Add InPlacePodVerticalScaling feature gate and drop disabled fields.
5. ResizePolicy validation & defaulting and Resources mutability for CPU/Memory.
6. Various fixes from code review feedback (originally committed on Apr 12, 2022)
KEP: /enhancements/keps/sig-node/1287-in-place-update-pod-resources
* Add tracker types and tests
* Modify ResourceEventHandler interface's OnAdd member
* Add additional ResourceEventHandlerDetailedFuncs struct
* Fix SharedInformer to let users track HasSynced for their handlers
* Fix in-tree controllers which weren't computing HasSynced correctly
* Deprecate the cache.Pop function
When StatefulSetAutoDeletePVC feature gate is enabled, StatefulSet
controller updates ownerReferences on managed PVCs. To be able to pass
OwnerReferencesPermissionEnforcement admission, it must have permissions to
delete PVCs.
Dependencies need to be updated to use
github.com/container-orchestrated-devices/container-device-interface.
It's not decided yet whether we will implement Topology support
for DRA or not. Not having any toppology-related code
will help to avoid wrong impression that DRA is used as a hint
provider for the Topology Manager.
The controller uses the exact same logic as the generic ephemeral inline volume
controller, just for inline ResourceClaimTemplate -> ResourceClaim.
In addition, it supports removal of pods from the ReservedFor field when those
pods are known to not need the claim anymore. At the moment, only this special
case is supported. Removal of arbitrary objects would imply granting full read
access to all types to determine whether a) an object is gone and b) if the
current incarnation is the one which is listed in ReservedFor. This may get
added later.
cd54bd94e9 removes the
handlers for /spec from the kubelet server.
Cleanup the RBAC rules as well.
