Welcome to the release of CRI-O v1.0.2!

goroutines leak

During performance testing we noticed an increased memory usage. We tracked that
down to cmux leaking goroutines. We fixed that by simply adding a read timeout
to the golang's http server. Performance are back to normal again.

• v4.0.0 -> a389bdde4dd695d414e47b755e95e72b7826432c github.com/godbus/dbus

Highlights of the release:

• Support for adding default mounts for all containers.
  This allows injecting secrets like the ones used to install rpms from repositories.
• Bugs, stability and performance fixes.
• New kpod commands
  • kpod login
  • kpod logout

This version is designed to work with kube 1.7.x. We will release a rc1 of a version that works with k8s 1.8.x shortly.

Highlights of the release:

• Support for limiting container log size.
• Added a cri-o client package for info/inspect endpoints.
• Minikube support.

We are now close to releasing 1.0 as the number of bugs go down.

Thanks,

We are happy to announce the release of CRI-O v1.0.0-rc2
Big thanks to our maintainers and contributors from Red Hat, Intel, SUSE, Hyper, IBM and others.

The main reason behind this second RC is to fix a failure to pull official images from the Docker Hub.
Highlights of the release:

• Fix image pulling.
  Docker Hub started serving manifest lists for different architectures for official images (e.g. redis). That resulted in CRI-O not being able to pull official images from Docker Hub.
• Correctly set hostname in pods.
• SELinux fixes.
• Updated kubernetes to v1.7.6.
• Fixes to seccomp handling.
• Other fixes and more tests.

List of changes is available here https://github.com/kubernetes-incubator/cri-o/compare/v1.0.0-rc1...v1.0.0-rc2?expand=1

Highlights of the release:

• Bugs, stability and performance fixes
• Moved from kubernetes 1.6 to 1.7
• cadvisor isupport
• Full kube e2e tests coverage. We are now gating pull requests on kube e2e (we were gating them just on node-e2e).
• Continue working on kpod. New commands added:
  • kpod cp
  • kpod diff
  • kpod export
  • kpod logs
  • kpod mount
  • kpod ps
  • kpod rename
  • kpod stats
  • kpod umount

This release contains minor features improvements as we’re totally focused on bugs, stability and, above all, performance fixes for 1.0.0.
