Publishing components

Store and run signed artifacts from an OCI registry.

Vino tools will automatically pull from an OCI registry if the passed filename isn’t found on the local filesystem. If you don’t have an OCI registry handy, you can start one easily with Docker.

docker run -it --rm -p 5000:5000 registry

Note: This will spin up an insecure local registry. It’s suitable for testing but production registries will need more configuration.

Publish your artifact

Run the following command to publish build/my_component_s.wasm to the path and tag test/my-component:latest on the registry we spun up at

oras push build/my_component_s.wasm

Fetch your remote components

To run your components remotely all you do is pass the registry URL to vow in place of the filename we’ve used previously. vow will take care of fetching and caching the remote artifact.

$ vow run greet --latest --insecure -- \
 --input="Jane Doe"
{"output":{"value":"Hello Jane Doe"}}

Hopefully everything feels like it “just works” which is what Vino should always feel like. Now that we can make simple connections between local and remote components, it’s time to step it up to more complex configurations. For that, we need schematics.
