}

# Generic LUA record
resource "powerdns-gslb_lua" "foo" {
  zone = "home.internal."
  name = "foo"
  record {
    rrtype = "A"
    ttl = 5
    snippet = "ifportup(8082, {'10.0.0.1', '10.0.0.2'})"

PowerDNS tuning

Update your pdns.conf configuration file to enable LUA records and DNS update features.

enable-lua-records=yes
dnsupdate=yes

Then enable the TSIG mechanism, AXFR and DNSUPDATE on your dns zone test.internal

pdnsutil create-tsig-key tsigkey hmac-sha256
pdnsutil set-meta test.internal TSIG-ALLOW-DNSUPDATE tsigkey
pdnsutil set-meta test.internal TSIG-ALLOW-AXFR tsigkey
pdnsutil set-meta test.internal ALLOW-DNSUPDATE-FROM 0.0.0.0/0
