1.21.14-do.0

DigitalOcean Kubernetes (DOKS) is a managed Kubernetes service. Deploy Kubernetes clusters with a fully managed control plane, high availability, autoscaling, and native integration with DigitalOcean Load Balancers and volumes. You can add node pools using shared and dedicated CPUs, and NVIDIA H100 GPUs in a single GPU or 8 GPU configuration. DOKS clusters are compatible with standard Kubernetes toolchains and the DigitalOcean API and CLI.

• Updates to system components:

  • Updated to kernel to Linux 5.10.120.
    • This is an upgrade from Linux 4.19 on earlier DOKS 1.21 patch versions. This upgrade is necessary to address a limitation in BPF program size on kernels prior to Linux 5.1 that can lead to degraded cluster state where worker nodes are unable to provision new network namespaces for pods.
  • Updated to Kubernetes v1.21.14

• Changes to system components:

  • Disabled Cilium’s eBPF-based NodePort handling in favor of kube-proxy’s as it does not support graceful termination properly in v1.10. (This also disables the eBPF implementations for features depending on NodePort handling in Cilium in favor of kube-proxy, namely host IP and external IP processing.)
