Is the Docker image supposed to be public?

When I first tried the run_in_container.sh, it tried to run a "codex" image. But there is no public codex image on Docker Hub. (I was able to build it locally after a few tries.)

Perhaps this is intentional (for now), in which case please go ahead and close this issue! But just in case, did you perhaps actually upload it to Docker Hub, but forgot to set it to be public, so it's working only inside OpenAI?
