HAPROXY + ACME (Standalone)



  • I've currently had HAProxy & Acme working with DNS-Manual for a little over a year, Thanks to PiBa... If I remembered the username correctly...

    But I'm finding the need to redo my DNS text records every 3 months a little cumbersome.
    I've tried a few times to follow several tutorials when the certs expired with no luck...

    Question: DNS-NSUpdate / RFC 2136 vs Standalone which is better?
    Question: DNS-NSUpdate (Info) is provided by my domain host if they have this service available?

    A little about the setup:

    Custom GUI TCP Port
    80 and 443 Rules in place
    Working HAProxy HTTP to HTTPS Redirect

    HAproxy
    Added frontend HTTP ACL for acme, path starts with, /.well-known/acme-challenge/ with Action http-request redirect to rule scheme https
    Added frontend HTTPS ACL for acme, path starts with, /.well-known/acme-challenge/ with Action use backend, backend-acme

    Added backend backend-acme forward to 127.0.0.1 port 4002 and no health check.

    Acme
    Added cert domain.com standalone HTTP server with HTTP listen port set to 4002

    hmmm, just tried creating a cert with one domain and it worked...
    orginal cert(s) had multiple sub domains under each, does this not work with standalone?
    can someone confirm this...

    As you said, the latter is :

    cumbersome

    and not advised : see https://www.netgate.com/docs/pfsense/certificates/acme-validation.html#standalone

    DNS-NSUpdate / RFC 2136

    IMHO : the best ! I real set-it-and-forget-it method.
    As you mentioned : it needs to be supported by "the other side", or to be more precise : the place where your domain name is registered, probably your registrar or, even better : on some (master) DNS server that serves the zone of your domain that you administer yourself - see here for an RFC 2136 example.

    Most 'big' registrar support some procedure that is implemented by the acme package.
    Just cross-check https://github.com/Neilpang/acme.sh/tree/master/dnsapi with what your regisrar offers you.
    If not, no panic : read https://github.com/Neilpang/acme.sh/tree/master/dnsapi - scroll down to see what is possible.
    If none : start thinking about moving your domain name - and/or read https://github.com/Neilpang/acme.sh/wiki/DNS-alias-mode
