detectHostRulesFromEnv ony supports domain names, should also support URLs with paths

Tell us more.

I want to use self-hosted renovate with detectHostRulesFromEnv.
I want to detect private docker images from ghrc.io/myprivaterepo. Currently it seems to me like I can only set DOCKER_GHCR_IO_TOKEN=the-token which is for the entirety of ghcr.io, not scoped to just my org.

Is there a way to pass a token to a URL name like ghcr.io/myprivaterepo through detectHostRulesFromEnv?
I don't want to use the token for all ghcr.io access, just for particular repos.

I'm aware that I can pass this with a host-rule in the json config, I'm just wondering if it would be doable with env vars only.

It's not supported today. You would need to figure out a way to support this syntax in env variables, because / is not supported directly

Yeah, that's what I've figured, it's pretty difficult to represent it as an env var. Maybe a combination of env-vars though, one declaring an alias, and then use alias in the other env var, eg:

HOST_ALIAS_PRIVATEGHCR="ghcr.io/myprivaterepo"
DOCKER_PRIVATEGHCR_TOKEN=mytoken

Then the logic could first load the aliases, then try to resolve the alias before evaluating the second env var.

I think you'd be better off to just stringing your hostRules and expose them as RENOVATE_HOST_RULES

[reegnz]

Yeah, probably. Thanks for that hint.
