- Updated to Cilium 1.10.1
- Enabled full kube-proxy replacement
- Enabled the
enable-egress-gatewayandenable-bpf-masqueradeoptions to allow use of Cilium’s egress gateway feature
- Updated to CoreDNS v1.8.4

- Updated to DO CCM v0.1.33
- Updated to Linux kernel-image-4.19.0-17-amd64, which includes the
target_core_modmodule that was missing from previous releases
- Updated to Cilium 1.10.1
- Configured graceful node shutdown parameters on the Kubelet to allow graceful workload termination when worker nodes are powered off
- Removed kube-proxy, since Cilium is now configured for full kube-proxy replacement mode. Clusters created on 1.20 and previous releases will have kube-proxy deleted during upgrade.
- Raised
pid_maxto 4194304 to help avoid PID exhaustion on large workers - Configured PID and CPU reservations for system components to improve node stability
- Renamed the managed
kube-state-metricsServiceAccount to avoid conflicts with customer installations of kube-state-metrics. Upgraded clusters will retain thekube-state-metricsServiceAccount, but it can be safely removed.
