Using a "guix publish"er as a proxy?

Using a "guix publish"er as a proxy?

Hi,

I wonder if I could make a "guix publish" process into a proxy.

Eg. I configure my local systems to use substitute-url
"http://guix-buiilder.local:8888/" and guix-buiilder.local will reach
out to e.g. berlin.guixsd.org if it does not have the substitute.

That cannot be done currently.

However, what you can do is use the two URLs:

  --substitute-urls="http://guix-buiilder.local:8888 https://berlin…"

HTH!

Rethinking this, this might even be hard to solve. Since the "client"
downloads a list of all existing substitutes, the proxy would need to
fetch the substitutes from the remote side on demand. Probably this is
not worth the effort for now.

This is what I'm currently using. But if is one of the servers listed
there is lagging, this delays the build process. And every local system
will reach out to the remote servers again.
