* clusterapi: Add 'watch' verb to scale-from-zero example If the 'get' and 'list' verbs are present, but the 'watch' verb is absent, the autoscaler reports an error. For example: cluster-autoscaler-b8949d8b9-76vcd E1006 22:11:43.056176 1 reflector.go:148] k8s.io/client-go/dynamic/dynamicinformer/informer.go:108: Failed to watch infrastructure.cluster.x-k8s.io/v1beta2, Resource=vcdmachinetemplates: unknown * Update with make generate * Add pdb filtering to remainingPdbTracker * Convert replicated, system, not-safe-to-evict, and local storage pods to drainability rules * Convert scale-down pdb check to drainability rule * Pass DeleteOptions once during default rule creation * Split out custom controller and common checks into separate drainability rules * Filter out disabled drainability rules during creation * Refactor GetPodsForDeletion logic and tests into simulator * Fix custom controller drainability rule and add test coverage * Add unit test for long-terminating pod past grace period * Removed node drainer, kept node termination handler * Add HasNodeGroupStartedScaleUp to cluster state registry. - HasNodeGroupStartedScaleUp checks wheter a scale up request exists without checking any upcoming nodes. * Add kwiesmueller to OWNERS jbartosik et al are transitioning off of workload autoscalers (incl vpa and addon-resizer). kwiesmueller is on the new team and has agreed to take on reviewer/approver responsibilities. * Add information about provisioning-class-name annotation. * Remove redundant if branch * Add mechanism to override drainability status * Log drainability override * fix(cluster-autoscaler-chart): if secretKeyRefNameOverride is true, don't create secret Signed-off-by: Jonathan Raymond <jonwraymond@gmail.com> * fix: correct version bump Signed-off-by: Jonathan Raymond <jonwraymond@gmail.com> * Initialize default drainability rules * feat: each node pool can now have different init configs * ClusterAPI: Allow overriding the kubernetes.io/arch label set by the scale from zero method via environment variable The architecture label in the build generic labels method of the cluster API (CAPI) provider is now populated using the GetDefaultScaleFromZeroArchitecture().Name() method. The method allows CAPI users deploying the cluster-autoscaler to define the default architecture to be used by the cluster-autoscaler for scale up from zero via the env var CAPI_SCALE_ZERO_DEFAULT_ARCH. Amd64 is kept as a fallback for historical reasons. The introduced changes will not take into account the case of nodes heterogeneous in architecture. The labels generation to infer properties like the cpu architecture from the node groups' features should be considered as a CAPI provider specific implementation. * Update image builder to use Go 1.21.3 Some of Cluster Autoscaler code is now using features only available in Go 1.21. * Add node-delete-delay-after-taint to FAQ * Reports node taints. * Add debugging-snapshot-enabled back * Rename comments, logs, structs, and vars from packet to equinix metal * Rename types * fix: provider name to be used in builder to provide backward compatibility Signed-off-by: Ayush Rangwala <ayush.rangwala@gmail.com> * Rename comments, logs, structs, and vars from packet to equinix metal * Created a new env var for metal to replace/support packet env vars as usual * Support backward compatibility for PACKET_MANAGER env var Signed-off-by: Ayush Rangwala <ayush.rangwala@gmail.com> * fix: refactor cloud provider names Signed-off-by: Ayush Rangwala <ayush.rangwala@gmail.com> * Documents startup/status/ignore node taints. * Adding price info for c3d (Price for preemptible instances is calculated as: (Spot price / On-demand price) * instance prices) * Bump CA golang to 1.21.3 * cloudprovider/exoscale: update limits/quotas URL https://portal.exoscale.com/account/limits has been deprecated in favor of https://portal.exoscale.com/organization/quotas.

update cluster-autoscaler to 1.28 * Bump builder images to go 1.21.5 * feat: add metrics to show target size of every node group * deprecate unused node-autoprovisioning-enabled and max-autoprovisioned-node-group-count flags Signed-off-by: Prashant Rewar <108176843+prashantrewar@users.noreply.github.com> * fix(hetzner): insufficient nodes when boot fails The Hetzner Cloud API returns "Actions" for anything asynchronous that happens inside the backend. When creating a new server multiple actions are returned: `create_server`, `start_server`, `attach_to_network` (if set). Our current code waits for the `create_server` and if it fails, it makes sure to delete the server so cluster-autoscaler can create a new one immediately to provide the required capacity. If one of the "follow up" actions fails though, we do not handle this. This causes issues when the server for whatever reason did not start properly on the first try, as then the customer has a shutdown server, is paying for it, but does not receive the additional capacity for their Kubernetes cluster. This commit fixes the bug, by awaiting all actions returned by the create server API call, and deleting the server if any of them fail. * Add VSCode workspace files to .gitignore * Remove vpa/builder and switch dependabot updates to component Dockerfiles * fix: updated readme for hetzner cloud provider * Add error details to autoscaling backoff. Change-Id: I3b5c62ba13c2e048ce2d7170016af07182c11eee * Make backoff.Status.ErrorInfo non-pointer.

I noticed that with this change CA get rate limited and slows down significantly (especially during large scale downs). * Pass Burst and QPS client params to capi k8s clients * Dependency update for CA 1.29.1 * feat: support `--scale-down-delay-after-*` per nodegroup Signed-off-by: vadasambar <surajrbanakar@gmail.com> feat: update scale down status after every scale up - move scaledown delay status to cluster state/registry - enable scale down if `ScaleDownDelayTypeLocal` is enabled - add new funcs on cluster state to get and update scale down delay status - use timestamp instead of booleans to track scale down delay status Signed-off-by: vadasambar <surajrbanakar@gmail.com> refactor: use existing fields on clusterstate - uses `scaleUpRequests`, `scaleDownRequests` and `scaleUpFailures` instead of `ScaleUpDelayStatus` - changed the above existing fields a little to make them more convenient for use - moved initializing scale down delay processor to static autoscaler (because clusterstate is not available in main.go) Signed-off-by: vadasambar <surajrbanakar@gmail.com> refactor: remove note saying only `scale-down-after-add` is supported - because we are supporting all the flags Signed-off-by: vadasambar <surajrbanakar@gmail.com> fix: evaluate `scaleDownInCooldown` the old way only if `ScaleDownDelayTypeLocal` is set to `false` Signed-off-by: vadasambar <surajrbanakar@gmail.com> refactor: remove line saying `--scale-down-delay-type-local` is only supported for `--scale-down-delay-after-add` -

we don't want to initialize processors in static autoscaler because anyone implementing an alternative to static_autoscaler has to initialize the processors - and initializing specific processors is making static autoscaler aware of an implementation detail which might not be the best practice Signed-off-by: vadasambar <surajrbanakar@gmail.com> refactor: revert changes related to `clusterstate` - since I am going with observer pattern Signed-off-by: vadasambar <surajrbanakar@gmail.com> feat: add observer interface for state of scaling - to implement observer pattern for tracking state of scale up/downs (as opposed to using clusterstate to do the same) -

The method allows CAPI users deploying the cluster-autoscaler to define the default architecture to be used by the cluster-autoscaler for scale up from zero via the env var CAPI_SCALE_ZERO_DEFAULT_ARCH. Amd64 is kept as a fallback for historical reasons. The introduced changes will not take into account the case of nodes heterogeneous in architecture. The labels generation to infer properties like the cpu architecture from the node groups' features should be considered as a CAPI provider specific implementation. * Update image builder to use Go 1.21.3 Some of Cluster Autoscaler code is now using features only available in Go 1.21. * Add node-delete-delay-after-taint to FAQ * Reports node taints. * Add debugging-snapshot-enabled back * Rename comments, logs, structs, and vars from packet to equinix metal * Rename types * fix: provider name to be used in builder to provide backward compatibility Signed-off-by: Ayush Rangwala <ayush.rangwala@gmail.com> * Rename comments, logs, structs, and vars from packet to equinix metal * Created a new env var for metal to replace/support packet env vars as usual * Support backward compatibility for PACKET_MANAGER env var Signed-off-by: Ayush Rangwala <ayush.rangwala@gmail.com> * fix: refactor cloud provider names Signed-off-by: Ayush Rangwala <ayush.rangwala@gmail.com> * Documents startup/status/ignore node taints. * Adding price info for c3d (Price for preemptible instances is calculated as: (Spot price / On-demand price) * instance prices) * Bump CA golang to 1.21.3 * cloudprovider/exoscale: update limits/quotas URL https://portal.exoscale.com/account/limits has been deprecated in favor of https://portal.exoscale.com/organization/quotas.

When creating a new server multiple actions are returned: `create_server`, `start_server`, `attach_to_network` (if set). Our current code waits for the `create_server` and if it fails, it makes sure to delete the server so cluster-autoscaler can create a new one immediately to provide the required capacity. If one of the "follow up" actions fails though, we do not handle this. This causes issues when the server for whatever reason did not start properly on the first try, as then the customer has a shutdown server, is paying for it, but does not receive the additional capacity for their Kubernetes cluster. This commit fixes the bug, by awaiting all actions returned by the create server API call, and deleting the server if any of them fail. * Add VSCode workspace files to .gitignore * Remove vpa/builder and switch dependabot updates to component Dockerfiles * fix: updated readme for hetzner cloud provider * Add error details to autoscaling backoff.

we don't want to initialize processors in static autoscaler because anyone implementing an alternative to static_autoscaler has to initialize the processors - and initializing specific processors is making static autoscaler aware of an implementation detail which might not be the best practice Signed-off-by: vadasambar <surajrbanakar@gmail.com> refactor: revert changes related to `clusterstate` - since I am going with observer pattern Signed-off-by: vadasambar <surajrbanakar@gmail.com> feat: add observer interface for state of scaling - to implement observer pattern for tracking state of scale up/downs (as opposed to using clusterstate to do the same) -

create a separate observer directory - implement `RegisterScaleUp` function in the clusterstate - TODO: resolve syntax errors Signed-off-by: vadasambar <surajrbanakar@gmail.com> feat: use `scaleStateNotifier` in place of `clusterstate` -

return it instead and let the caller decide what to do with it Signed-off-by: vadasambar <surajrbanakar@gmail.com> refactor: change pointers to values in `NGChangeObserver` interface - easier to work with - remove `expectedAddTime` param from `RegisterScaleUp` (not needed for now) - add tests for clusterstate's `RegisterScaleUp` Signed-off-by: vadasambar <surajrbanakar@gmail.com> refactor: conditions in `GetScaleDownCandidates` - set scale down in cool down if the number of scale down candidates is 0 Signed-off-by: vadasambar <surajrbanakar@gmail.com> test: use `ng1` instead of `ng2` in existing test Signed-off-by: vadasambar <surajrbanakar@gmail.com> feat: wip static autoscaler tests Signed-off-by: vadasambar <surajrbanakar@gmail.com> refactor: assign directly instead of using `sdProcessor` variable -

It also corrects the behavior when a server has been physically deleted from Hetzner Cloud. Signed-off-by: Maksim Paskal <paskal.maksim@gmail.com> * [v1.29] fix(hetzner): hostname label is not considered The Node Group info we currently return does not include the `kubernetes.io/hostname` label, which is usually set on every node. This causes issues when the user has an unscheduled pod with a `topologySpreadConstraint` on `topologyKey: kubernetes.io/hostname`. cluster-autoscaler is unable to fulfill this constraint and does not scale up any of the node groups. Related to kubernetes#6715 * Remove shadow err variable in deleteCreatedNodesWithErros func * fix: scale up broken for providers not implementing NodeGroup.GetOptions() Properly handle calls to `NodeGroup.GetOptions()` that return `cloudprovider.ErrNotImplemented` in the scale up path. * Update k/k vendor to 1.29.5 for CA 1.29 * Rebase * Fx gomock * Rename ARM_BASE_URL * Backport kubernetes#6528 [CA] Fix expectedToRegister to respect instances with nil status into CA1.29 * Backport kubernetes#6750 [CA] fix(hetzner): missing error return in scale up/down into CA1.29 * PR#6911 Backport for 1.29: Fix/aws asg unsafe decommission kubernetes#5829 * CA -
