We run Harbor and mirror every base image using its Proxy Cache feature, it's quite nice. We've had this setup for years now and while it works fine, Harbor has some rough edges.

I came here to mention that any non-trivial company depending on Docker images should look into a local proxy cache. It’s too much infra for a solo developer / tiny organization, but is a good hedge against DockerHub, GitHub repo, etc downtime and can run faster (less ingress transfer) if located in the same region as the rest of your infra.
