Authentication

Some registries (or specific images) may require you to be authenticated. For those, you can modify cup.json like this:

{ "registries": { "<YOUR_REGISTRY_DOMAIN_1>": { "authentication": "<YOUR_TOKEN_1>" // Other options }, "<YOUR_REGISTRY_DOMAIN_2>" { "authentication": "<YOUR_TOKEN_2>" // Other options }, // ... } // Other options }

You can use any registry, like ghcr.io, quay.io, gcr.io, etc.

⚠️
For Docker Hub, use registry-1.docker.io
