## Summary - Build custom multus-cni image with a patch that fixes sandbox cleanup deadlock - When CNI ADD never completes, DEL now returns success instead of failing - Prevents stale sandbox name reservations from permanently blocking pod creation ## Problem After a node disruption (e.g. DRBD/kube-ovn issues during upgrade), containerd accumulates stale sandbox name reservations. Cleanup fails because multus calls delegate plugins for DEL without cached state, and they reject the incomplete config. This blocks all new pods on the affected node indefinitely. ## Changes - Add `images/multus-cni/` with Dockerfile and patch for custom image build - Add `image` target to multus Makefile - Add multus to root Makefile build targets - Update DaemonSet template to use the custom image ## Upstream - PR: https://github.com/k8snetworkplumbingwg/multus-cni/pull/1498 - Tracking: https://github.com/cozystack/cozystack/issues/2310 ## Test plan - [x] Built and pushed image to ghcr.io/cozystack/cozystack/multus-cni - [x] Deployed to cluster, verified fix in multus logs ("no cache found... skip DEL") - [x] Force-deleted stuck pods, all 24 pods started successfully within 70s <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added Multus CNI container image build process to the system. * **Bug Fixes** * Fixed delete operation behavior when cache is unavailable, improving reliability of network cleanup operations. * **Chores** * Updated Multus CNI container image reference in deployment configuration to latest version with build improvements. <!-- end of auto-generated comment: release notes by coderabbit.ai --> |
