I'm trying to use Bitbucket Pipelines with a private repo on Docker Hub, but I've been spidering around the docs and can't for the life of me find out how to authorize BBP to access it. I tried anyway to see what would happen, and the build unsurprisingly says it can't find that image.
How can I authorize BBP to access the private repo? The BB Pipelines docs assure me that "we support public and private Docker images from Docker Hub or your own registry," but don't mention *how*.
