referencing accessories by container name?

[gammons]

Hi there,

What's the best way to reference accessories? As far as I understand it, the only option to reference an accessory is by its internal, docker-based ip address. That isn't ideal for a lot of reasons. Does (or could) kamal create a bridge network so that running containers can reference accessories by their container name? Or am I not understanding something? Thanks!

@gammons This can be achieved if you run the web app and accessory on the same server, create a docker network on the server, then define the network on deploy.yml

create a network on the server
docker network create -d bridge private

set server and accessory network config

servers:
  web:
    hosts:
      - xx.xx.xx.xx
    options:
      network: "private"

accessories:
  db:
    image: mariadb:latest
    host: xx.xx.xx.xx
    port: 3306
    env:
      clear:
        MYSQL_ROOT_HOST: '%'
      secret:
        - MYSQL_ROOT_PASSWORD
        - MYSQL_USER
        - MYSQL_PASSWORD
        - MYSQL_DATABASE
    options:
      network: "private"
    directories:
      - data:/var/lib/mysql
