* Fix cluster-autoscaler clusterapi sample manifest This commit fixes sample manifest of cluster-autoscaler clusterapi provider. (cherry picked from commit a5fee21) * Adding functionality to cordon the node before destroying it. This helps load balancer to remove the node from healthy hosts (ALB does have this support). This won't fix the issue of 502 completely as there is some time node has to live even after cordoning as to serve In-Flight request but load balancer can be configured to remove Cordon nodes from healthy host list. This feature is enabled by cordon-node-before-terminating flag with default value as false to retain existing behavior. * Set maxAsgNamesPerDescribe to the new maximum value While this was previously effectively limited to 50, `DescribeAutoScalingGroups` now supports fetching 100 ASG per calls on all regions, matching what's documented: https://docs.aws.amazon.com/autoscaling/ec2/APIReference/API_DescribeAutoScalingGroups.html ``` AutoScalingGroupNames.member.N The names of the Auto Scaling groups. By default, you can only specify up to 50 names. You can optionally increase this limit using the MaxRecords parameter. MaxRecords The maximum number of items to return with this call. The default value is 50 and the maximum value is 100. ``` Doubling this halves API calls on large clusters, which should help to prevent throttling. * Break out unmarshal from GenerateEC2InstanceTypes Refactor to allow for optimisation * Optimise GenerateEC2InstanceTypes unmarshal memory usage The pricing json for us-east-1 is currently 129MB. Currently fetching this into memory and parsing results in a large memory footprint on startup, and can lead to the autoscaler being OOMKilled. Change the ReadAll/Unmarshal logic to a stream decoder to significantly reduce the memory use. * use aws sdk to find region * update readme * Update cluster-autoscaler/cloudprovider/aws/README.md Co-authored-by: Guy Templeton <guyjtempleton@googlemail.com> * Merge pull request kubernetes#4274 from kinvolk/imran/cloud-provider-packet-fix Cloud provider[Packet] fixes * Fix bug where a node that becomes ready after 2 mins can be treated as unready. Deprecated LongNotStarted In cases where node n1 would: 1) Be created at t=0min 2) Ready condition is true at t=2.5min 3) Not ready taint is removed at t=3min the ready node is counted as unready Tested cases after fix: 1) Case described above 2) Nodes not starting even after 15mins still treated as unready 3) Nodes created long ago that suddenly become unready are counted as unready. * Improve misleading log Signed-off-by: Sylvain Rabot <sylvain@abstraction.fr> * dont proactively decrement azure cache for unregistered nodes * Cluster Autoscaler: fix unit tests after kubernetes#3924 was backported to 1.20 in kubernetes#4319 The backport included unit tests using a function that changed signature after 1.20. This was not detected before merging because CI is not running correctly on 1.20. * Cluster Autoscaler: backport Github Actions CI to 1.20 (kubernetes#4366) * annotate fakeNodes so that cloudprovider implementations can identify them if needed * move annotations to cloudprovider package * fix 1.19 test * remove flaky test that's removed in master * Cluster Autoscaler 1.20.1 * Make arch-specific releases use separate images instead of tags on the same image This seems to be the current convention in k8s. * Cluster Autoscaler: add arch-specific build targets to .gitignore * CA - AWS - Instance List Update 03-10-21 - 1.20 release branch * CA - AWS - Instance List Update 29-10-21 - 1.20 release branch * Cluster-Autoscaler update AWS EC2 instance types with g5, m6 and r6 * CA - AWS Instance List Update - 13/12/21 - 1.20 * Merge pull request kubernetes#4497 from marwanad/add-more-azure-instance-types add more azure instance types * Cluster Autoscaler 1.20.2 * Add `--feature-gates` flag to support scale up on volume limits (CSI migration enabled) Signed-off-by: ialidzhikov <i.alidjikov@gmail.com> * CA - AWS Cloud Provider - 1.20 Static Instance List Update 02-06-2022 * Cluster Autoscaler - 1.20.3 release * sync_file updates & other changes * Updating vendor against git@github.com:kubernetes/kubernetes.git:e3de62298a730415c5d2ab72607ef6adadd6304d (e3de622) * fixed some declaration errors Co-authored-by: Kubernetes Prow Robot <k8s-ci-robot@users.noreply.github.com> Co-authored-by: Hidekazu Nakamura <hidekazuna@gmail.com> Co-authored-by: atul <atul.aggarwal@cleartax.in> Co-authored-by: Benjamin Pineau <benjamin.pineau@datadoghq.com> Co-authored-by: Adrian Lai <aidy@loathe.me.uk> Co-authored-by: darkpssngr <shreyas300691@gmail.com> Co-authored-by: Guy Templeton <guyjtempleton@googlemail.com> Co-authored-by: Vivek Bagade <vivek.bagade92@gmail.com> Co-authored-by: Sylvain Rabot <sylvain@abstraction.fr> Co-authored-by: Marwan Ahmed <marwanad@microsoft.com> Co-authored-by: Jakub Tużnik <jtuznik@google.com> Co-authored-by: GuyTempleton <guy.templeton@skyscanner.net> Co-authored-by: sturman <4456572+sturman@users.noreply.github.com> Co-authored-by: Maciek Pytel <maciekpytel@google.com> Co-authored-by: ialidzhikov <i.alidjikov@gmail.com>
