Welcome to the v1.2.7 release of containerd!

The seventh patch release for containerd 1.2 introduces OCI
image descriptor annotation support and contains fixes for
containerd shim logs, container stop/deletion, cri plugin
and selinux.

It also contains several important bug fixes for goroutine and
file descriptor leakage in containerd and containerd shims.

Notable Updates

  • Support annotations in the OCI image descriptor, and filtering image by annotations. #3254
  • Support context timeout in ttrpc which can help avoid containerd hangs when a shim is unresponsive. ttrpc#31
  • Fix a bug that containerd shim leaks goroutine and file descriptor after containerd restarts. ttrpc#37
  • Fix a bug that a container can't be deleted if first deletion attempt is canceled or timeout. #3264
  • Fix a bug that containerd leaks file descriptor when using v2 containerd shims, e.g. containerd-shim-runc-v1. #3273
  • Fix a bug that a container with lingering processes can't terminate when it shares pid namespace with another container. moby/moby#38978
  • Fix a bug that containerd can't read shim logs after restart. #3282
  • Fix a bug that shim_debug option is not honored for existing containerd shims after containerd restarts. #3283
  • cri: Fix a bug that a container can't be stopped when the exit event is not successfully published by the containerd shim. #3125, #3177
  • cri: Fix a bug that exec process is not cleaned up if grpc context is canceled or timeout. cri#1159
  • Fix a selinux keyring labeling issue by updating runc to v1.0.0-rc.8 and selinux library to v1.2.2. opencontainers/selinux#50
  • Update ttrpc to f82148331ad2181edea8f3f649a1f7add6c3f9c2. #3316
