could not build variables_hash

[abh]

kube-lego by defaults add an annotation saying

ingress.kubernetes.io/whitelist-source-range: 0.0.0.0/0

this makes the nginx ingress controller add

geo $the_real_ip $deny_host1.example.com_/.well-known/acme-challenge {
    default 1;

    0.0.0.0/0 0;
}
geo $the_real_ip $deny_host2.example.com_/.well-known/acme-challenge {
    default 1;

    0.0.0.0/0 0;
}

which in turns makes the configuration fail with

I tried with the latest beta and with quay.io/aledbf/nginx-ingress-controller:0.130. It looks like this was introduced in 07cdee5. The commit message doesn't say why the change was done.

The commit message doesn't say why the change was done.

This refactoring was required to get working the whitelist range when the controller is confiured with proxy protocol

oh, now in the light of day: maybe the geo stuff is okay (just a warning that it's weirdly configured) and it's the variables_hash change - 8837cf9 - that made it croak.

Closing. Fixed in #809
