Upstream Repo needs a new tag.
It also looks like the current docker images is missing at least a patch version of the upstream module.
Latest is v0.1.1

Hi @kevinkirkup!

Packaging we use to feed the docker images actually already has this otel version included: nginx/pkg-oss@1b00f76

Docker image bump is going to happen in a couple of days with a new release of nginx (and thus modules too), so stay tuned!

The updated nginx:alpine-otel is up. Can you please test @kevinkirkup ? Thanks!
