Loose config during restart bind running in a docker container

[thraak]

Hi all,

I setup a docker container using the docker-compose.yml as described in the documentation here. It works for some tests. But when I restart the container it looses all configurations except the configs in the mapped data-folder (/data). In my case I adjusted the mapping to use a docker volume for the persistence of the data-folder and this works. I would like to do this also for the other configurations: What is to do to retain bind configurations like additional accounts, changed password, updates of the application and so on. It seems these informations aren't stored in the data-folder. How to setup the docker-compose.yml to map the folder with these data to a persistent folder at the underlying storage of the computer.

My docker-compose.yml looks like this:

version: '3.7'

services: bind: restart: always image: sameersbn/bind:latest #9.16.1-20200524 dns: - "www.xxx.yyy.zzz" ports: - "53:53/udp" - "53:53/tcp" - "10000:10000/tcp" volumes: - data_volume:/data:rw

volumes: data_volume: external: false
