Welcome to the v1.0.0-beta.1 release of cri-containerd!

Note: This repository will be moved into containerd organization after this release.

Highlights

This release we mainly focused on bug fix. Notable bug fixes:

  • Get rid of default RLIMIT_NOFILE for containers. (Issue: #515, PR: #516, @Random-Liu)
  • Fix an issue that privileged pod can't run on kernel with version <3.16. (Issue: #517, PR: #518, @Random-Liu)
  • Cache pod IP for performance and also unblock VM-based container support. (Issue: #524, PR: #525, @abhi)
  • Add a flag skip-imagefs-uuid to skip retrieving image filesystem UUID. Users will be able to try cri-containerd on node with mdev or ZFS. Note: kubelet will not be able to get imagefs capacity or perform imagefs disk eviction when skip-imagefs-uuid=true. (Issue: #325, #399, #509, PR: #510, @Random-Liu)
