Unable to configure API_PREFIX

[mweinelt]

I've tried reverse proxying the salt-api endpoint on /api as described in the the nginx tutorial, but there doesn't seem to be a way to tell saltpad to look for the salt api below that path, as API_URL does not accept an URL but a hostname/port.

TypeError: Hostname "salt.xy.z.net:443/api" contains characters other than [A-Z0-9.-]

We will need to "proxy" requests from nginx to salt-api on a specific URL, let's choose "/api", your configuration should now looks like:

    # Salt-api specific
    location /api/ {
        proxy_pass       http://localhost:8000/;
        proxy_set_header Host      $host;
        proxy_set_header X-Real-IP $remote_addr;
    }

No mention how to update settings.json accordingly.
