Thank you!

@aeneasr the issue is not resolved completely, Dockerfile needs to be updated because your release image also needs the rego folder to run. People using docker images will still face this issue. For my local build, I did something like this for release container.

COPY --from=builder /go/pkg/mod/github.com/ory /go/pkg/mod/github.com/ory

This line copies everything in local ory folder to release image ory folder. I needed this for my environment. You might just need keto/engine/ladon/rego in this case.

Hm that's strange, we're using packer to build the binary which should include the source code - otherwise the docker image wouldn't start at all (it does tho last time I checked). See this line.
