Try pushing to docker hub and fail

Is pushing to docker hub supported?

wasm-to-oci --log debug push target/wasm32-wasi/debug/hello-world-rust.wasm docker.io/jingweno/wasm:1234

I had the same problem.

I just checked, pushing to ECR is supported. Perhaps docker hub behaves a bit differently.

$ wasm-to-oci push ./target/wasm32-wasi/debug/hello-world-rust.wasm 215737051855.dkr.ecr.us-west-2.amazonaws.com/wasm:latest

Yes, currently Docker Hub actively rejects media types outside of a clearly defined list - I also updated the readme to clearly state that pushing to Docker Hub is indeed expected to fail.

(For a bit more context, this project expects the registry to allow arbitrary artifacts - as described by the proposed OCI Artifacts proposal. Given that the proposal is fairly new, it is indeed expected that, unless explicitly tested, a registry will actively reject unknown media types, and so will reject WebAssembly modules.)

We have tested this implementation extensively with the upstream Docker Distribution project and Azure Container Registry - thanks a lot for testing ECR, I will also give it a go and update the readme.

Might be worth retrying this, given https://www.docker.com/blog/announcing-docker-hub-oci-artifacts-support/, and following up at docker/roadmap#135 if there's any remaining blockers.

this works now, here i pushed a rust wasm http service

wasm-to-oci push target/wasm32-wasi/release/server.wasm docker.io/creslin/http-rust:1

returns
