I am using dind in my CI job and building docker images successfully.
As an idea I wondered if I pushed docker images to our container registry and then change the Dockerfile from:
FROM node
to
FROM registry.gitlab.com/mygroup/infrastructure/docker-images/node
it might speed our build times up, but by using this approach it always errors with a 403 even though I logged into the registry before calling docker build
Is this even possible and would it speed up builds?
