I am trying to setup wild card certificate but since https01 is no longer valid to be used for wild card certs, it’s making it more difficult.
Based on this documentation https://cert-manager.io/docs/configuration/acme/dns01/
I have to register or move my dns to one of those cloud providers, hence we are using self-managed private cloud with our own bare-metal servers. Looking at setting up acme-dns, there is no straight forward setup for it and we don’t want to move our dns to it either as we have our own dns server already set.
I tried the following: https://github.com/joohoi/acme-dns but there is nothing explains what txt I need to add into my domain zones
time="2020-05-02T08:48:02Z" level=info msg="2020/05/02 08:48:02 [ERROR][auth.domain.com] failed to obtain certificate: acme: Error -> One or more domains had a problem:" time="2020-05-02T08:48:02Z" level=info msg="[auth.domain.com] acme: error: 403 :: urn:ietf:params:acme:error:unauthorized :: No TXT record found at _acme-challenge.auth.domain.com, url: (attempt 3/3; challenge=dns-01)"
Can someone please advise?
