* 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 <[email protected]> * fix: correct version bump Signed-off-by: Jonathan Raymond <[email protected]> * 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 <[email protected]> * 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 <[email protected]> * fix: refactor cloud provider names Signed-off-by: Ayush Rangwala <[email protected]> * 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 <[email protected]> * 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 <[email protected]> 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 <[email protected]> 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 <[email protected]> refactor: remove note saying only `scale-down-after-add` is supported -

because it is not true anymore - we are supporting all `--scale-down-delay-after-*` flags per nodegroup Signed-off-by: vadasambar <[email protected]> test: fix clusterstate tests failing Signed-off-by: vadasambar <[email protected]> refactor: move back initializing processors logic to from static autoscaler to main - 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 <[email protected]> refactor: revert changes related to `clusterstate` - since I am going with observer pattern Signed-off-by: vadasambar <[email protected]> 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) -

instead of `ScaleDownCandidatesSortingProcessor` and `ScaleDownCandidatesDelayProcessor` separately Signed-off-by: vadasambar <[email protected]> refactor: add scale state notifier to list of default processors - initialize processors for `NewDefaultScaleDownCandidatesProcessor` outside and pass them to the fn - this allows more flexibility Signed-off-by: vadasambar <[email protected]> refactor: add observer interface - create a separate observer directory - implement `RegisterScaleUp` function in the clusterstate - TODO: resolve syntax errors Signed-off-by: vadasambar <[email protected]> feat: use `scaleStateNotifier` in place of `clusterstate` - delete leftover `scale_stateA_observer.go` (new one is already present in `observers` directory) - register `clustertstate` with `scaleStateNotifier` - use `Register` instead of `Add` function in `scaleStateNotifier` - fix `go build` - wip: fixing tests Signed-off-by: vadasambar <[email protected]> test: fix syntax errors - add utils package `pointers` for converting `time` to pointer (without having to initialize a new variable) Signed-off-by: vadasambar <[email protected]> feat: wip track scale down failures along with scale up failures - I was tracking scale up failures but not scale down failures - fix copyright year 2017 -> 2023 for the new `pointers` package Signed-off-by: vadasambar <[email protected]> feat: register failed scale down with scale state notifier - wip writing tests for `scale_down_candidates_delay_processor` - fix CI lint errors - remove test file for `scale_down_candidates_processor` (there is not much to test as of now) Signed-off-by: vadasambar <[email protected]> test: wip tests for `ScaleDownCandidatesDelayProcessor` Signed-off-by: vadasambar <[email protected]> test: add unit tests for `ScaleDownCandidatesDelayProcessor` Signed-off-by: vadasambar <[email protected]> refactor: don't track scale up failures in `ScaleDownCandidatesDelayProcessor` -

return it instead and let the caller decide what to do with it Signed-off-by: vadasambar <[email protected]> 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 <[email protected]> refactor: conditions in `GetScaleDownCandidates` - set scale down in cool down if the number of scale down candidates is 0 Signed-off-by: vadasambar <[email protected]> test: use `ng1` instead of `ng2` in existing test Signed-off-by: vadasambar <[email protected]> feat: wip static autoscaler tests Signed-off-by: vadasambar <[email protected]> refactor: assign directly instead of using `sdProcessor` variable -

change scale state observer interface's `RegisterFailedScaleup` to reflect latest changes around clusterstate's `RegisterFailedScaleup` in `master` Signed-off-by: vadasambar <[email protected]> test: fix clusterstate test failing Signed-off-by: vadasambar <[email protected]> test: fix failing orchestrator test Signed-off-by: vadasambar <[email protected]> refactor: rename `defaultScaleDownCandidatesProcessor` -> `combinedScaleDownCandidatesProcessor` - describes the processor better Signed-off-by: vadasambar <[email protected]> refactor: replace `NGChangeObserver` -> `NodeGroupChangeObserver` - makes it easier to understand for someone not familiar with the codebase Signed-off-by: vadasambar <[email protected]> docs: reword code comment `after` -> `for which` Signed-off-by: vadasambar <[email protected]> refactor: don't return error from `RegisterScaleDown` - not needed as of now (no implementer function returns a non-nil error for this function) Signed-off-by: vadasambar <[email protected]> refactor: address review comments around ng change observer interface - change dir structure of nodegroup change observer package - stop returning errors wherever it is not needed in the nodegroup change observer interface - rename `NGChangeObserver` -> `NodeGroupChangeObserver` interface (makes it easier to understand) Signed-off-by: vadasambar <[email protected]> refactor: make nodegroupchange observer thread-safe Signed-off-by: vadasambar <[email protected]> docs: add TODO to consider using multiple mutexes in nodegroupchange observer Signed-off-by: vadasambar <[email protected]> refactor: use `time.Now()` directly instead of assigning a variable to it Signed-off-by: vadasambar <[email protected]> refactor: share code for checking if there was a recent scale-up/down/failure Signed-off-by: vadasambar <[email protected]> test: convert `ScaleDownCandidatesDelayProcessor` into table tests Signed-off-by: vadasambar <[email protected]> refactor: change scale state notifier's `Register()` -> `RegisterForNotifications()` - makes it easier to understand what the function does Signed-off-by: vadasambar <[email protected]> test: replace scale state notifier `Register` -> `RegisterForNotifications` in test - to fix syntax errors since it is already renamed in the actual code Signed-off-by: vadasambar <[email protected]> refactor: remove `clusterStateRegistry` from `delete_in_batch` tests - not needed anymore since we have `scaleStateNotifier` Signed-off-by: vadasambar <[email protected]> refactor: address PR review comments Signed-off-by: vadasambar <[email protected]> fix: add empty `RegisterFailedScaleDown` for clusterstate -
