We still have to review the metric names and +structure before having something we are all comfortable supporting in the long +run but we now have comprehensive metrics for all containers running on +containerd. + +## Distribution + +After hitting a major milestone of getting a proof of concept for end to end +pull and run, this week the focus was on getting that code in the right place +and figure out where the implementation gaps are. + +### Image to OCI Spec + +* https://github.com/docker/containerd/pull/660 + +We merged support for getting an image config that was pulled off of a registry +and generating a spec based on the image properties in the `ctr` command. This +will let you pull images off of a registry and run them based on the config and +how the image was built. + +Its very simple at the moment but will will be porting over the default spec +and generation code from Docker soon into a package that can be easily consumed +by clients of containerd. + +You can test this by running: + +```console +bash +sudo dist pull docker.io/library/redis:alpine +sudo ctr run --id redis -t docker.io/library/redis:alpine +``` + +### Image handlers + +* https://github.com/docker/containerd/pull/638 + +We refactored the fetch command into a more generic image handler interface. As +we look forward to supporting the full oci image spec as well as the Docker +distribution specifications, we are removing any opinionated code to make +distribution as generalized and efficient as possible. + +### Image listing now with full image size + +```console +$ dist images +REF TYPE DIGEST SIZE +docker.io/library/redis:latest application/vnd.docker.distribution.manifest.v2+json sha256:1b358a2b0dc2629af3ed75737e2f07e5b3408eabf76a8fa99606ec0c276a93f8 71.0 MiB +``` + +## Snapshot driver improvements + +* https://github.com/docker/containerd/pull/635 + +The `overlay` and `btrfs` driver implementations are now fully implemented and +share an implementation for metadata storage. This new metadata storage package +allows not only making snapshot drivers easier, but allow us to focus on making +our existing drivers more resilient and stable once.
