Decoupled DNS Server

[stevebrainng]

Hi @stefanpejcic, Thanks once again.

I was looking at the opencli source code find the bind DNS and get to know how flexible it will be to swap to our in-house DNS server setup, instead of the native BIND implementations.

One thing I have come to like about the OpenPanel setup is the decoupled nature of how you've done thing, and it's the way we've been trying to structure our entire infrastructure, leading to having our DNS server cluster on seperate servers, our current cPanel server are configured to use the DNS server.

I don’t recommend modifying the existing code to use your own DNS server instead of BIND, as you'd have to maintain and test all changes yourself on updates.. a better option:

• disable the DNS Zone Editor: 'dns' module in OpenAdmin > Settings > Modules
• create a custom plugin to allow users to manage dns zones on your in-house dns server

PS, I would also remove the bind9 service from /root/docker-compose.yml and named from /etc/openpanel/openadmin/config/notifications.ini to prevent it from starting or being used by other modules *(this is what --skip-dns-server flag does on install)

Also, each opencli command supports pre and post hooks, so you can easily hook into domain-related actions like domain creation to run your own commands before or after. For example, you can on your in-house dns server create DNS zones, set up nameservers, PTR records, etc.

For example, when a user adds a new domain, the command used is opencli domains-add, so to hook into that, just create a file: /etc/openpanel/openpanel/hooks/post_domains-add.sh - this script will run automatically after a domain is added from the OpenPanel UI.

to run a script before the process, then use pre instead of post in file name: /etc/openpanel/openpanel/hooks/pre_domains-add.sh

also, each attribute is passed back to your script, so for example:

opencli domains-add <DOMAIN_NAME> <USERNAME> [--docroot DOCUMENT_ROOT] [--php_version N.N] [--skip_caddy --skip_vhost --skip_containers --skip_dns] --debug

would pass all those flags back to your script:

bash /etc/openpanel/openpanel/hooks/post_domains-add.sh <DOMAIN_NAME> <USERNAME> [--docroot DOCUMENT_ROOT] [--php_version N.N] [--skip_caddy --skip_vhost --skip_containers --skip_dns] --debug
