Container registries this node pulls app images from. The primary is tried first; if it's slow or unreachable, the next one in the list is tried automatically.
Registries are tried in priority order on every app install. Changing the primary takes effect on the next install — existing containers keep running on whatever image they already pulled.
{{ r.name || r.url }}
PRIMARY HTTP{{ r.url }}
The URL should be of the form host[:port]/namespace — for example ghcr.io/myorg or 192.168.1.50:3000/apps. Registries are added to the end of the list; use "Make primary" to reorder.
