Possibility of saving a slave without necessity of having a mount point

[arvanus]

Hi, I'm preparing a new remove slave server, and would like to run inside a cluster without a fixed volume, it would be very useful to have the possibility os passing my servers/domains list as an environment variable parameter, and in the startup the container would create the required named.conf.default-zones file
The docker-compose would be something like this (suggestions are welcome)

version: '3.5'

services:
  bind9:
    restart: unless-stopped
    image: labbsr0x/dns-bind9
    ports:
      - "53:53/udp"
      - "53:53/tcp"
    environment:
            MASTER_DOMAINS: 192.168.1.1:domain1.com,192.168.3.1:domain2.com

The startup script would then create the required file

If you agree, I could do this change and pull a patch

Thanks

Hello @arvanus, I am not sure the current maintainers have time available to discuss the suggested improvement.

You can always fork this repo, do your modifications and open a PR. In the meantime, while your PR is being reviewed (which might take a long time), I suggest you to build your own image and use that instead in your project.
