Docker Confd Config

This image provides a configuration file /confd-out/config from environment variables via volume to be used in other containers.

Example configuration

Using nginx just to have a running container, so compose up will not exit. Replace nginx with your service and use the configuration file directly or e.g. via symlinks (ln -s /confd-out/config /etc/nginx/conf.d/custom.conf).

Write a docker-compose.yml (included in github source):

version: "3.2"

volumes:
  confd-out:

services:
  nginx:
    image: nginx:alpine
    volumes:
    - confd-out:/confd-out

  confd:
    image: intershopde/docker-confd
    environment:
      CONFIG_CONTENT: |
        multiline
        configuration
        with empty line

    volumes:
    - confd-out:/confd-out

Then run:

docker-compose up -d
docker exec -it docker-confd_nginx_1 /bin/sh
/ # cat /confd-out/config
> multiline
> configuration
> with empty line
>
/ # exit
docker-compose down -v
