Bumps github.com/containerd/containerd from 1.5.0-beta.4 to 1.7.0-beta.0.

Release notes

Sourced from github.com/containerd/containerd's releases.

containerd 1.7.0-beta.0

Welcome to the v1.7.0-beta.0 release of containerd! This is a pre-release of containerd

The eighth major release of containerd includes new functionality alongside many improvements. This release is intended to be the last major release of containerd 1.x before 2.0. Some functionality in this release may be considered experimental or unstable, but will become stable or default in 2.0. This release still adheres to our backwards compability guarantees and users who do not use or enable new functionality should use this release with the same stability expectations. The previous 1.6 release has also become a long term stable release for users who prefer releases with mostly stability improvements and wish to wait a few releases for new functionality.

This is a beta release and includes some functionality which is not yet complete. While most APIs are finalized before merge, they are subject to change until the official release.

Highlights

Sandbox API (experimental)

The sandbox API provides a new way of managing containerd's shim, providing more flexibility and functionality for multi-container environments such as Pods and VMs. This API makes it easier to manage these groups of containers at a higher level and offers new extension points for shim implementations and clients.

Road to 2.0

Refactoring

There are multiple places in the code today which are being targeted for refactoring to make long term support easier and to provide more extension points.

The CRI plugin is the most complex containerd plugin with a wide range of functionality. A major effort in this release and before 2.0 involves moving functionality out of the single CRI plugin into smaller-scoped containerd plugins, such that they can be used and tested independenty. The new sandbox and distribution interfaces provide one example of this, but it also being done for image and network management.

The version of ttrpc has been updated this release to support streaming, allowing existing grpc services to use ttrpc. Services are being refactored to allow ttrpc implementations, which can be served via shim and accessed using the new sandbox management capability.

• Remove gogoproto.customtype (#6699)
• Remove enumvalue_customname, goproto_enum_prefix and enum_customname (#6708)
