(Josh) - Milestone tracking: - <https://github.com/opencontainers/image-spec/milestone/14> - <https://github.com/opencontainers/distribution-spec/milestone/6> - Discussion on the registry ability to not include annotations in referrers response - <https://github.com/opencontainers/distribution-spec/pull/367> - Recommend to refuse the manifest push rather than alter the referrers response per descriptor or filter out responses - Limit descriptor size to 40kb for a manifest with a subject - 40kb * 100 responses per page = 4mb limit on index - registries can then implement pagination with a fixed 100 entries per page rather than checking each additional descriptor for the limit - some clients already limit individual annotations to 4kb - allows arbitrary annotations for future use cases, but with a bounded max size - Registries MAY reject a manifest push that exceeds these limits - _add your items_ ## December 28, 2022 Canceled ## December 22, 2022 Canceled ## December 15, 2022 **Recording**: https://youtu.be/uuBb-2NTYIw ### Attendees: - Brandon Mitchell - Tianon - Jesse Butler - Michael Brown - Sajay Antony - Mike Brown - Jason Hall - Jon Johnson - Toddy Mladenov - Samuel Karp - - _add yourself_ ### Note Taker: - _add note taker_ ### Actionable Agenda Items: - Who's taking notes?

- _add your items_ ### Presentation/Discussion Agenda Items: - Ways to bring the Nix ecosystem closer to OCI - Maybe a new "non-conflicting" layer type? - Could work for other, too: eg. _Guix_ ### Notes: - Nix/Guix "layers" - Non-conflicting (disjoint mount points) - Immutable - Need to support numerous tiny images, no artificial limits. - Nix/Guix ideomatic usage - No "base image" - Turtles all the way down! - Read-only paths can be done with https://github.com/opencontainers/runtime-spec/blob/main/config-linux.md#readonly-paths - Jon Johnson: Seems like two things to consider: 1. How to represent these images (image-spec) 2. How to unpack these differently from overlay (runtime-spec) - Tianon Gravi: runtime-spec doesn't specify unpacking though, that's runtime-specific (runtime-spec just specifies "rootfs" and it's implementation defined how to create that from an image) O:) - Nisha Kumar: The problem with regarding to running a /store like rootfs is putting the right binary in the right place such that the container runtime can find it - Brandon Mitchell: I'm wondering if the implementation could be as easy as an annotation that indicates the name of the non-conflicting path, which has the potential to be backwards compatible. - John Ericson: Sounds great!! ## November 10, 2022 **Recording**: https://youtu.be/HV_4mACIWrY ### Attendees: - Brandon Mitchell - Jason Hall - Phil Estes - Derek McGowan - Mike Brown (IBM) - Josh Dolitsky - Jon Johnson - Kevin Parsons - Sajay Antony - Christian Kniep - Kazu - Brian Goff - Tianon - Toddy - Michael Brown (AWS) - Ramkumar Chinchani (zot/Cisco) - _add yourself_ ### Note Taker: - _add note taker_ ### Actionable Agenda Items: - Who's taking notes? - [Jason] wasi/wasm change needs image-spec approvers 🙏: https://github.com/opencontainers/image-spec/pull/964 - [Jason] Dockerhub doesn't actually support "OCI Artifacts" - continued harmful confusion about these terms - We should clarify that "OCI Artifacts" is this: https://github.com/opencontainers/image-spec/blob/main/artifact.md - ...and not this: https://github.com/opencontainers/artifacts - Jason's AI from OCI Summit to migrate artifact author guidance to image-spec, then archive/delete `artifacts` repo. - Tianon: "subject" field issue with Docker Hub is fixed as of today! 😇 - [Jason] referrers API: "registries MAY hoist the manifest contents into the `data` of the descriptor - which means we can change "annotations MUST be hoisted" to "annotations MAY be hoisted" - clients should be prepared to fetch manifests if they want to filter on annotation data - Jon's issue: https://github.com/opencontainers/distribution-spec/issues/357 ### Presentation/Discussion Agenda Items: - _add your items_ ### Notes: ## November 3, 2022 **Recording**: https://youtu.be/kjleG_01EqQ ### Attendees: - Brandon Mitchell - Josh Dolitsky - Sajay Antony - Mike Brown (IBM) - Michael Brown (AWS) - Jesse Butler - Tianon - ASP - Bjorn Neergaard - Cory Snider - Brian Goff - Nisha Kumar - Ramkumar Chinchani (zot/Cisco) ### Note Taker: - _add note taker_ ### Actionable Agenda Items: - Who's taking notes? - Road to releasing 1.1.

Clients should still consider them when moving images (for backward compatibility) but in general SHOULD NOT produce new layers with that type." - Wasm considerations for image-spec [Jason] - Wasm is using OCI images to package and distribute (that's good!) - ...but currently only building single-platform images, and lying about their OS+arch being `linux/amd64` (that's bad!) - want to do better, but image-spec guidance is lacking - `.platform.os` field is `REQUIRED` but not meaningful to Wasm - guidance is to use values of Go's `GOOS` and `GOARCH` - As specified, this would mean `os=js`, `arch=wasm` - Go's Wasm support is lagging far behind Rust and TypeScript. - aside: `GOARCH=wasm` is 32-bit -- `wasm64` may come later - aside: `amd64` variants [#852](https://github.com/opencontainers/image-spec/issues/852) - Wasm may have variants (`spin` and `slight` today) -- should they register them with OCI? - They seem okay with `os=wasi`, `arch=wasm`, `variant=spin` (etc) - **Specific asks:** - specifying an exception to the `GOOS` rule for `wasi`? - specifying known variants for when `arch=wasm`, but you can also BYO? - Questions from Jon: - what's the layer media type? (A: `application/vnd.docker.image.rootfs.diff.tar.gzip`) - do they set the entrypoint? (A: No, not today, but we could recommend/require it) - Resuming interrupted PATCH request (Brandon) - API to get status of an upload is not defined - Procedure to get the current "Location" and "Range" is not defined by OCI - Docker API has a `GET /v2/<repo>/blobs/uploads/<uuid>` ([ref](https://github.com/distribution/distribution/blob/5cb406d511b7b9163bff9b6439072e4892e5ae3b/docs/spec/api.md#upload-progress)) - Related: <https://github.com/opencontainers/distribution-spec/issues/352> - New Netlify image is needed <https://github.com/opencontainers/opencontainers.org/issues/120> (Brandon) - Embedding Platform in Config <https://github.com/opencontainers/image-spec/pull/949> (Brandon) ### Notes: ## October 6, 2022 **Recording**: https://youtu.be/8X8vxWohmqA ### Attendees: - Brandon Mitchell - _add yourself_ ### Note Taker: - _add note taker_ ### Actionable Agenda Items: - Who's taking notes? - _add your items_ ### Presentation/Discussion Agenda Items: - _add your items_ - https://hackmd.io/nZzK_4AfRz-xgya6KkqseA ### Notes: ## September 29, 2022 **Recording**: https://youtu.be/DyUfew4gF3c ### Attendees: - Brandon Mitchell - ASP - Sajay Antony - Mike Brown (IBM) - _add yourself_ ### Note Taker: - _add note taker_ ### Actionable Agenda Items: - Who's taking notes? - _add your items_ ### Presentation/Discussion Agenda Items: - _add your items_ - OCI Meeting at KubeCon + virtual; October 24th from 10am to 12pm Central - RC2 is looking for votes: <https://github.com/opencontainers/image-spec/pull/958> ### Notes: ## September 22, 2022 **Recording**: https://youtu.be/F9gmGcKq9rM ### Attendees: - Lachlan Evenson - Mike Brown (IBM) - Brandon - Sajay - Tianon - Brian Goff - VBatts - Nisha - Ramkumar Chinchani ### Note Taker: - _add note taker_ ### Actionable Agenda Items: - Who's taking notes? - _add your items_ ### Presentation/Discussion Agenda Items: - Continue discussion on RC1 release [Brandon/Josh/Sajay] - Distribution spec - https://github.com/opencontainers/distribution-spec/pull/348 - Image Spec - https://github.com/opencontainers/image-spec/pull/953 - Reviewing 1.0.3 tagging option: <https://github.com/opencontainers/image-spec/issues/918> - _add your items_ ### Notes: ## September 15, 2022 **Recording**: https://youtu.be/jqtaJn6s6uo ### Attendees: - Samuel Karp - Sajay Antony - Brandon Mitchell - Josh Dolitsky - Michael Brown (IBM) - Michael Brown (AWS) - Brian Goff - Brandon Klein - _add yourself_ ### Note Taker: - _add note taker_ ### Actionable Agenda Items: - Who's taking notes? - _add your items_ ### Presentation/Discussion Agenda Items: - [Rename refers field to subject](https://github.com/opencontainers/image-spec/pull/950) - [Distribution Spec](https://github.com/opencontainers/distribution-spec/pull/344) - Need approval from maintainers @sajay - Discuss about process for release of spec to enable downstream consumers of the new specification @lachie83 (out on jury duty) - https://github.com/opencontainers/image-spec/issues/952 - https://github.com/opencontainers/distribution-spec/issues/337 - Remaining items: - <https://github.com/opencontainers/image-spec/issues/940> - <https://github.com/opencontainers/distribution-spec/issues/337> - Cutting an RC: 1.
