Korbs / Multi-Architecture OCI Image

Add multi-architecture support to an OCI image. > SudoVanilla uses [`buildah`](https://buildah.io/) instead of Docker, as it > builds valid OCI images that are supported by the SudoVanilla OCI Registry. > The [SudoVanilla OCI Registry](https://oci.registry.sudovanilla.org/) is > powered by [Zot Registry](https://zotregistry.dev/), a OCI-native container > image registry. ## Build or Pull Images **Build Image** ```bash buildah build -t registry.org/image:amd64 buildah build -t registry.org/image:amd64 ``` **Pull Image** ```bash buildah pull -t registry.org/image:arm64 buildah pull -t registry.org/image:arm64 ``` ## Manifest ### Create Use the `manifest create` command to generate a new OCI image index and give it the `latest` tag name. ```bash buildah manifest create registry.org/image:latest ``` ### Combine Images Using the previous images that was previously built or pulled, apply them to the newly created manifest: ```bash buildah manifest add registry.org/image:latest registry.org/image:arm64 buildah manifest add registry.org/image:latest registry.org/image:arm64 ``` ### Push Image You can now push the `latest` tag to your preferred registry and it'll be uploaded with both architecture images intact. ```bash buildah manifest push registry.org/image:latest ```
