Kubernetes - v1.23.16

Changelog since v1.23.15

Changes by Kind

API Change

• Kubernetes 1.23 is now built with go1.19.4. To match behavior of previous Kubernetes 1.23 patch releases:
• kube-apiserver defaults the GOGC setting to 63, to approximate go1.17 garbage collection memory performance in heavily loaded API servers
• kube-apiserver defaults the GODEBUG x509sha1 setting to x509sha1=1 to match go1.17 support for sha1 certificates (#113983, @liggitt) [SIG API Machinery, Apps, Architecture, Auth, Autoscaling, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Network, Node, Release, Scheduling, Storage and Testing]

Feature

• Kubernetes is now built with Go 1.19.5 (#115011, @cpanato) [SIG Cloud Provider, Release and Testing]

Bug or Regression

• Client-go: fixes potential data races retrying requests using a custom io.Reader body; with this fix, only requests with no body or with string / []byte / runtime.Object bodies can be retried (#113933, @liggitt) [SIG API Machinery]
• Do not include preemptor pod metadata in the event message (#115025, @mimowo) [SIG Scheduling]
• Failed pods associated with a job with parallelism = 1 are recreated by the job controller honoring exponential backoff delay again. However, for jobs with parallelism > 1, pods might be created without exponential backoff delay. (#115020, @nikhita) [SIG Apps]
• Fixed StatefulSet to show the valid status even if the new replica creation fails. (#112084, @gjkim42) [SIG Apps and Testing]
• Kube-apiserver: bugfix DeleteCollection API fails if request body is non-empty (#113967, @sxllwx) [SIG API Machinery]
• Kubelet: make the image pull time more accurate in event (#114430, @pacoxu) [SIG Node]
• [aws] Fixed a bug which reduces the number of unnecessary calls to STS in the event of assume role failures in the legacy cloud provider (#110706, @prateekgogia) [SIG Cloud Provider]
