v1.0.0-beta.1
containerd 1.0.0-beta.1 Welcome to the second beta release of `containerd`. The highlights of this release focus around making integrations much easier. The `Container.Extensions` field allows one to add arbitrary metadata, such as protobufs and json, to a container metadata object. The `Tasks.Wait` rpc makes waiting for containers to exit much simpler in practice. With this release, `containerd` now fully supports pulling multi-platform Docker and OCI images, complete with foreign layer support. Please try out the release binaries and report any issues at https://github.com/containerd/containerd/issues. Upgrading Label validation now requires that the key and value together are under 4096 bytes. If you had labels large than this size, metadata objects may need to be rewritten. The metrics API has been moved from `/metrics` to be versioned under `/v1/metrics` and is now slated to be covered under our release policy. The `Tasks` service now has a `Wait` rpc to make it easier to wait on container processes, eliminating race conditions that were hard to handle with events. Old clients will still work with events, but they will suffer from the problems that this change is meant to solve. Multi-Platform While `containerd` is fairly agnostic to the image format, the release of multi-platform images on Docker Hub caused some issues with the client-side pull support. `containerd` now properly handles multi-platform Docker and OCI images. This includes support for foreign layers. This means that one should be able to pull multi-platform images without issues for Linux and Windows, as well as most architectures. This works even if the platform doesn't support the particular image. Container Extensions A new field, `Container.Extensions`, supports storing integration specific structures directly in `containerd`. This allows drivers like Docker and CRI-containerd to store their own metadata objects in `containerd`. This obviates the need for secondary storage systems and ensures updates follow the same transaction semantics as other parts of `containerd`. At the same time, it also avoids problems with "label bloat" when storing more complex metadata. JSON and protobuf are supported. New Maintainer We want to welcome a new maintainer to `containerd`, Akihiro Suda. The container ecosystem would be as strong as it is today without his tireless efforts. We are excited to have him on board and his presence will ensure that `containerd` will be a strong platform.

v1.0.0-beta.0
containerd 1.0.0-beta.0 After a large push for stability changes, we now present containerd 1.0.0-beta.0. With this release, going forward, our focus will be on not breaking integrations. If we do push a beta that breaks something, please let us know immediately so we can update our processes and procedures to avoid breaks in the future. While we are making the above the committment, we will make exceptions if critical design changes are required or if there are security issues. Release Process The release process and versioning guarantees have been laid out in RELEASES.md. It identifies the release process, versioning, branching, support horizon and backporting processes for containerd. Upgrading As a matter of policy, there is no compatibility with previous alpha releases, so it is recommended that existing installations be cleared out to avoid future issues. Existing clients should work but one may encounter compilation errors due to changes. The name of the field `Container.RootFS` has been changed to `Container.SnapshotKey`. Existing clients should work with out change, but when upgrading deamons, the storage location of this value has changed. If this is a problem, please reach out and we can work out a migration solution. Metrics The main addition for this release is support for inline container metrics access on the Tasks service. The container metrics, previously available via the prometheus API, are now made available directly through the GRPC API to support use cases that are focused on single containers rather than aggregrates.

v1.0.0-alpha4
containerd 1.0.0-alpha4 With this weeks release, we are starting to become more stable. Many fixes related to rounding out core features and usability. We have our first documentation available, oriented towards getting started with containerd. This is the first release where we have no backwards incompatible changes to the GRPC API. There are some changes to the metadata storage layout, so please check upgrading for details. Please download the binaries provided and let the bears get at 'em. Please report issues through https://github.com/containerd/containerd/issues. Your feedback is extremely important at this stage, so please don't be bashful about letting us know what you think. Upgrading With respect to the GRPC API, there have only been additions to add labels to snapshot. All existing integrations should continue working with this release without changes. The storage format has had some changes to store labels and runc state has been relocated. Removing the contents of `/var/lib/containerd` is recommend before running this new version. This will cause loss of containers and image data. Let us know if this is a problem. Documentation We now have guides for [Getting Started](https://github.com/containerd/containerd/blob/master/docs/getting-started.md), [Operations](https://github.com/containerd/containerd/blob/master/docs/ops.md) and [Namespacing and Multi-tenancy](https://github.com/containerd/containerd/blob/master/docs/namespaces.md). Please take some time to read them and get to know containerd. The [godoc](https://godoc.org/github.com/containerd/containerd) has also been updated with new descriptions. Snapshot Labels Snapshots can now be decorated with labels on `Prepare`, `Commit` and `Update`. This is useful to associated snapshots with various components in containerd. Snapshot Command The arguments naming and order now correctly match the `Snapshotter` interface. Ordering of arguments may be affected. Make sure to use the help before using these commands if you are unsure. State Directory The runtime state directory has been brought back. Previously, this stored ephemeral container data associated with running containers. It was removed because checkpoint data was much too large for `tmpfs` used for the the `/run` directory. The checkpoint data is now in the main containerd directory, while the ephemeral data resides in `/run/containerd`. Access performance for `runc` should increase and old runtime data should be cleaned up on reboot with this change. API stability Tooling for GRPC API stability has been added. When protobufs are built, the descriptors for the entire symbol set that make up the API are aggregated into a single file. Changes that affect the API will show in these files, making it much easier to identify differences that aren't apparent in proto files. At each minor release, these files will be snapshotted. Go API Additions While there are several changes to the Go API, a few highlights include an option to kill the process process on delete, `WithProcessKill` and the ability to set the cgroup path and hostname options on the the runc specification. Solaris Build Support The project now builds on solaris.

v1.0.0-alpha3
containerd 1.0.0-alpha3 Another released alpha brings us closer to a stable release! This release contains more changes to the event system, cleanup of the process execution model and several bug fixes. Please download the binaries provided and light them on fire. Please report issues through https://github.com/containerd/containerd/issues. Your feedback is extremely important at this stage, so please don't be bashful about letting us know what you think. Upgrading With changes to the `Tasks` service and the `Events` service, it is recommend to full upgrade containerd and any constituent shim processes. Running with previous versions may effect task startup and event distribution from the shim. These changes were done to ensure API consistency. No changes to the `ctr` tool or storage formats should affect compatibility. If there are changes that affecting compatibility that weren't listed here, please file an issue. Process Exec More work has been undertaken to merge the behavior of container tasks and exec processes. The `Task` object no longer exists. The user now interacts with only processes. The main container processes is started through `Start` method, while processes can be added to the container with `Exec`. Event Filters Events now support full filtering. Filters act on events at publish time, per subscriber, allowing a subscriber to receive only relevant events. The same filtering syntax and behavior used on other APIs has been added here except that we autogenerate the available fields using protobuf definitions. The following example will match all events having to do with tasks in the `bb` namespace: ```console $ ctr events 'topic~=/tasks/.+,namespace==bb' ``` Event specific data can even be selected upon. The following example will match *any* event that has a `container_id` field with the value `mycontainer`. ```console $ ctr events 'event.container_id==mycontainer' ``` The above will actually decode event data, if known to containerd, and match regardless of the particular type, allowing this to act on unrelated event types without changing syntax. Events API The `Publish` method no longer takes an `Envelope` message as an argument and a new `Forward` method has been added. While this change seems superficial, it actually has the effect of avoiding a serialization round trip when forwarding events from other backends, such as container shims. This change is not backwards compatible with previous alpha releases. Unmanaged Root Filesystem Container's can now be run without snapshots using the `ctr` tool. If the `--rootfs` flag is provided, the positional argument for image will now be interpreted as a filesystem path. The following is an example: ```console ctr run --rootfs --tty /my/root/fs mycontainer ``` Shim CGroup Container shims may not be started in a specific cgroup with a parameter passed at task creation time.

v1.0.0-alpha2
containerd 1.0.0-alpha2 With another week comes another alpha release. With this release, we have focused on increasing overall quality and consistency across the code base. Several new tests have been added, along with attention to refactoring in various subsystems to match current needs. Unfortunately, we had to break some interfaces to achieve these goals. See the section on Upgrading for details. Again, please download the binaries provided and kick the tires. Please report issues through the https://github.com/containerd/containerd/issues. Your feedback is extremely important at this stage, so please don't be bashful about letting us know what you think. Upgrading Some backwards incompatible changes have been made to the GRPC API and the snapshotter storage format. See the sections on Events and Snapshotters for more details. To upgrade, you'll need to clear out the containerd root, which defaults to `/var/lib/containerd/`. All containers, images and metadata will be lost, if you do this. If this is a problem, please reach out and we can work out a migration script. If such a change was done from a production release, a migration script would have been provided. Also, make sure to update your clients to the latest version that picks up the new definition for the events service. This change would not be accepted in a full released version. Events After dealing with a few deadlock issues, the events subsystem has been completely refactored to match the existing use cases. Specifically, a lot of cruft around the original design, based on Go's context package has been removed. The use of go-events has been cleaned up to ensure correct subscription and distribution of events, in addition to ensuring correct teardown. The nomenclature has also been updated to better reflect familiar "publish" and "subscribe" models. If you closely examine #1246, you'll see that the usage of the `Publisher` interface is much simpler than the `WithTopic` approach. This should allow us to add events to more subsystems. The GRPC API for the Events service was updated to bring the service inline with these changes. Post and Stream have been replaced with Publish and Subscribe, respectively. Clients will have to be updated to use the new API endpoints. After these changes, adding proper filter support should be more straightforward. See a615a6fe for details. Snapshotter Previously, snapshots had an attribute `Readonly` that was only valid for `Active` snapshots. After looking at various conditionals, snapshot behavior and usage, we found that these snapshots were better represented as a discrete type, known as a "view snapshot". Unfortunately, we've add to break compatibility with the existing storage format to correctly enumerate the snapshot types. Users will have to remove the old storage and start from the scratch. See 863784f9 for details. Tar Tars with duplicated symlinks in disparate layers are now handled correctly. See afec478b for details. - Windows support - snapshot command now supports "commit" - More testing Windows Support Progress on supporting windows has received a major boost. Windows integration has been refactored to more closely follow existing changes throughout containerd. Commands A new command has been added to `ctr snapshot` to allow committing of active snapshots. The help output has been reordered to be alphabetical.

v1.0.0-alpha1
containerd 1.0.0-alpha1 We have followed up the initial alpha with this second release. There are a large number of changes to focus on API stability, error handling and several bug fixes. Again, please download the binaries provided and kick the tires. Please report issues through the https://github.com/containerd/containerd/issues. Your feedback is extremely important at this stage, so please don't be bashful about letting us know what you think. Commands Merged The most visible changes to users will be that the `dist` command has now been merged into `ctr`. We've found this to be much easier for demonstration, testing and deployment. For the most part, this change has moved the subcommands untouched under `ctr`. In addition to the command merge, all commands that mutate labels were changed from `set-labels` to the shorter `label`. The `snapshot` command has a few additions to display details in a tree format, as well as some tweaks to expose mounts. See 659e3d78 and 4dc02c09 for details. Since we are discussing command syntax, it is a good time to remind users that cli behavior will not be covered by the 1.0 version guarantees. We will only guarantee behavior of GRPC APIs, although we'll try to keep changes like this minimized. Event Topics The topics for task events have been tweaked to be more consistent. This could effect users that were matching on event topic. Please see a578730a for details.

v1.0.0-alpha0
containerd 1.0.0-alpha0 We are pushing the first containerd alpha release today. It includes a fully functional execution, content, snapshotting filesystems, and distribution layer. With the alpha release we wanted to make sure the GRPC API was in a good shape for people to start or finish the integrations for the 1.0 branch. Ideally, there will not be any major API changes after this release. We encourage users integrating containerd into their software and platforms to use our Go client, `import "github.com/containerd/containerd"`. We have not finalized this Go API at the time of the alpha release so that users can provide feedback and modifications can be made to the client to reduce code that containerd consumers have to write. During the alpha period, we will be working on integrating containerd into various projects and working out any rough edges or bugs. We will also be tagging a weekly alpha release going forward with fixes and updates during this phase.
