[Feature request]: Change defaults for `CA_HOSTNAME` and `CERTNAME`

[defnull]

Use Case

I started a new openvoxserver container with the custom hostname openvox as well as OPENVOXSERVER_HOSTNAME=openvox and assumed this is enough, but it is not:

• Calling puppetserver ca list fails because it tries to connect to https://puppet:8140.
• The CA certificate still lists DNS:puppet in addition to DNS:openvox.

The first issue is caused by CA_HOSTNAME defaulting to puppet instead of OPENVOXSERVER_HOSTNAME or hostname -f, which I find unintuitive. Setting CA_HOSTNAME=openvox solves this issue.

The second issue persists, even if I set CERTNAME=openvox. The puppet alt name seems to be hard coded somewhere?

Describe the solution you would like

A container with minimal configuration should use OPENVOXSERVER_HOSTNAME and fall back to hostname -f for all aspects that need to know the servers hostname. It should not assume that the hostname is puppet.

• OPENVOXSERVER_HOSTNAME should default to hostname -f
• CA_HOSTNAME should default to OPENVOXSERVER_HOSTNAME.
• CERTNAME should also default to OPENVOXSERVER_HOSTNAME.
• The server CA certificate should not contain puppet as an additional alt name unless this is explicitly requested by DNS_ALT_NAMES.

Describe alternatives you've considered

Documenting more prominently which config values are absolutely required if the hostname differs from puppet.

the variable can be set like you said. but to not have the puppet alt name, i think you have to raise an issue at https://github.com/OpenVoxProject/openvox-server or maybe https://github.com/OpenVoxProject/openvoxserver-ca ... but we are not using this yet i think.
