Welcome to the release of containerd v1.0.0-beta.3! *This is a pre-release of containerd* After rounding out the feature set in beta.2, we have taken a number of stability fixes. This release contains mostly bug fixes, code cleanup and improvements to useability of the client and ctr tool. Please try out the release binaries and report any issues at https://github.com/containerd/containerd/issues. `ctr` makeover `ctr` is getting a makeover! The end goal is for commands to be consistent and scoped. Most notably: - `push`, `pull` are now `images` subcommands: `ctr images push`, `ctr images pull` - `fetch`, `fetch-object`, and `push-object` are `content` subcommands - `rootfs unpack` is now `snapshot unpack` - `apply` no longer exists. RIP' Garbage collector improvements The garbage collector continues to improve with this release, including bug fixes on the client causing races and a new lease feature for making retention from the client easier. The lease API was added to make it easier for clients to prevent content and snapshots from being garbage collected while they are being actively worked on (such as from pull, import, or checkpoint). The API includes functions for creating, deleting, and listing leases. The lease gets attached to the context and the backend metadata store sees it and associates newly created content and snapshots with that lease. Leases are currently acquired and released automatically through the client. From the user perspective, fewer `gc.root` labels should be seen on client during pull/import operations or left over after a failed operation.
