Welcome to the v1.2.0 release of containerd!

The third major release of containerd brings both a mix of boring and
exciting changes. While fixing many bugs and continuing support for the
containerd 1.0 API, new APIs and interfaces have been added to allow
containerd to be more extensible and cover more use cases.

New V2 Runtime

A new v2 runtime has been added with a stable gRPC interface for managing
containers through external shims.

This allows runtime authors to easily integrate with containerd over a stable
API.

Various runtimes can be selected on a per container basis using the WithRuntime opt
or to test via ctr ctr run --runtime io.containerd.runc.v1.

Documentation

Updated CRI Plugin

Containerd 1.2 is validated against Kubernetes v1.11 and v1.12, but it is also compatible with Kubernetes v1.10.

To use containerd 1.2 with Kubernetes v1.10, be sure to run the stream server on an address accessible to the apiserver. A simple way is to set stream_server_address="" in the [plugins.cri] section of containerd.toml, so that cri plugin will automatically select a routable node address.

Kubernetes Runtime Class

Kubernetes Runtime Class introduced in Kubernetes 1.12 is supported.

Users can:

• Configure alternative runtime handlers with the config option plugins.cri.containerd.runtimes.runtime_handler_name, e.g. plugins.cri.containerd.runtimes.kata. (config.md)
• Use the alternative runtime handler in Kubernetes by creating RuntimeClass for the runtime handler, and specifying RuntimeClassName in the pod spec. (doc)

The plugins.cri.containerd.untrusted_workload_runtime config option and io.kubernetes.cri.untrusted-workload pod annotation are still functional, but start being deprecated. It is recommended to migrate to the RuntimeClass api.

Other Features

• Supported ProcMount option introduced in Kubernetes 1.12.
• Added a new config option plugins.cri.registry.auths for user to config default credentials for specific registries. (doc)
• Added a new config option plugins.cri.x509_key_pair_streaming for user to config a valid certificate for the stream server. (config.md)
• Added a runtime options field for shim v2 runtime. Use the options field to config runtime specific options, e.g. NoPivotRoot and SystemdCgroup for runtime type io.containerd.runc.v1. (See config.md)

Notable Changes

• cri plugin can see images pulled/imported into containerd by ctr images pull and ctr images import.
• CNI config is now dynamically reloaded when changed.
• IPv4 address is guaranteed to be selected, when there are both IPv4 and IPv6 addresses for a pod.
• Privileged untrusted workload is allowed, the workload will get privilege inside the sandbox.
• cri plugin stream server serves on http://localhost:0 by default. This is to work with the kubelet streaming proxy introduced in Kubernetes 1.11.
• Fixed an issue that a container can't be stopped when container processes are accidentally moved out of the container cgroups.
• cluster/health-monitor.sh in the release tarball will be deprecated next release. Please use Kubernetes health-monitor.sh instead.

New Proxy Plugins

A new proxy plugin configuration has been added to allow external snapshotters
be connected to containerd using gRPC.

Documentation

Managed /opt directory

A new Install method on the containerd client allows users to publish host level
binaries using standard container build tooling and container distribution tooling
to download containerd related binaries on their systems.

This can be used for v2 runtime authors to get their runtime shims on an existing
containerd system. It can also be used to install runc and other related tools.

> ctr content fetch docker.io/crosbymichael/runc:latest
> ctr install docker.io/crosbymichael/runc:latest

Documentation

Garbage Collection

Add support for cleaning up leases and content ingests to garbage collections.

Add expiration label to clean up temporary resources.

Image Importer

The image importer has been updated to support output from docker save. Users
of the ctr tool should take note of the usage change to ctr images import.
We continue to recommend not building tooling on top of the ctr tool.

API Changes

This release features a couple additions to the API. Clients may make use of
these new API features but should be able to handle cases when those features
are not implemented on the server. The Go client handles this automatically.

• Add ListStream method to containers API. This allows listing a larger
  number of containers without hitting message size limts.
• Add Sync flag to Delete in leases API. Setting this option will ensure
  a garbage collection completes before the removal call is returned. This can
  be used to guarantee unreferenced objects are removed from disk after a lease.

Other Improvements

Improved multi-arch image support using more precise matching and ranking

Please try out the release binaries and report any issues at
