version: "3"

### Creates a named network with the default bridge driver
# The network is shared between restheart and mongodb only
# See: https://docs.docker.com/engine/userguide/networking/dockernetworks/
# See: https://docs.docker.com/engine/reference/commandline/network_create/
networks:
   restheart-backend:

### Create a permanent, named data volume
# This makes much easier to identify where the mongodb data is stored on host
# See: https://docs.docker.com/engine/userguide/containers/dockervolumes/#mount-a-shared-storage-volume-as-a-data-volume
volumes:
   restheart-mongo-volume:

services:
    mongodb:
        image: mongo:5
        container_name: restheart-mongo
        command: ["--bind_ip", "restheart-mongo", "--replSet", "rs0"]

### Initiate MongoDB as a single node replica set
    mongodb-initiate:
      image: mongo:5
      networks:
         - restheart-backend
      depends_on:
         - mongodb
      entrypoint: bash -c "for i in {1..100}; do mongo  --host mongodb --eval 'if (!rs.status().ok) rs.initiate();' && break || sleep 2; done"
