Hey I have a Gitlab runner(kubernetes executor) that is building containers inside a pipeline.

The pipeline runs inside a pod with the image: quay.io/buildah/stable and fails while calling buildah bud .:

STEP 1/12: FROM docker.io/parity/parity:v2.5.13-stable
Trying to pull docker.io/parity/parity:v2.5.13-stable...

I tried recreating this in a new pod: kubectl run -it buildah --image containers/buildah --command tail -f /dev/null with a simpler Dockerfile:

FROM ubuntu
RUN touch /test
CMD ["echo", "hello"]

and it worked. Building with the actual project outside the pod also works. I couldn't figure out how to mount the project into the pod, so I haven't built the whole project in there yet.

So why doesn't it run in the gitlab runner? Can this maybe be a misconfiguration in the gitlab runner?
