lburgazzoli opened a new issue #2732: URL: https://github.com/apache/camel-k/issues/2732
Open Container Initiative (OCI) has defined [specs](https://github.com/opencontainers/image-spec) to enable the creation of interoperable tools for building, transporting, and preparing a container image to run, however - in practice - registries have a little to do with container images and we can think about them as a content addressable storage. In camel-k we have been struggling a lot about find an easy way to provide artifacts/blobs to the runtime and I think experimenting about leveraging OCI compatible registries could be a way to improve the situation. This is not a brand new novel idea as: - some discussion about leveraging container images have been happened already in the camel-k community - solo.io [leverages](https://github.com/solo-io/wasm/blob/master/spec/spec.md) container images to distribute WASM - there has been a recent talk about hacking the registry at [kubecon](https://t.co/hqeHSA4Yqf?amp=1) Since each `layer` is essential a blob (often a `tar.gz`) and that the `layer` definition has an optional `annotations` property that can hold arbitrary key/value paris, we can leverage it to identify camel-k artifacts (i.e. additional dependencies, resources, kamelets repositories, etc): ```json { "schemaVersion": 2, "layers": [{ "mediaType": "application/vnd.oci.image.layer.v1.tar+gzip", "size": 16724, "digest": "sha256:3c3a4604a545cdc127456d94e421cd355bca5b528f4a9c1905b15da2eb4a4c6b", "annotations": { "camel.apache.org.dependency": "com.acme:foo:1.0" } }, { "mediaType": "application/vnd.oci.image.layer.v1.tar+gzip", "size": 73109, "digest": "sha256:ec4b8955958665577945c89419d1af06b5f7636b4ac3da7f12184802ad867736", "annotations": { "camel.apache.org.kamelets.repository": "acme-kamelets" } } ] } ``` **NOTES**: 1. solo.io has introduced a set of additional `mediaType` values but that may not work with some registries or tools so IMHO, at this stage, it would be better not to introduce a custom media type and leverage annotations. 2. A further evolution would be to implement a [Kubernetes Container Storage Interface (CSI)](https://github.com/kubernetes-cs) to mount OCI layers to a POD -- This is an automated message from the Apache Git Service.
