MongoDB with Docker and initial seed

Some steps to create a MongoDB instance with initial data using Docker and Docker Compose

Create a JSON file called init.json with your document:

[
  {
    "name": "Kevin Martins",
    "birthday": "29 April , 1995",
    "nick": "Red King",
    "age": 24
  },
  {
    "name": "Kauan Martins",
    "birthday": "02 July , 2008",
    "nick": "Red as Floid",
    "age": 11
  }
]

Create a Dockerfile and copy your JSON file:

FROM mongo

COPY init.json /init.json
CMD mongoimport --host mongo --db reach-engine --collection users --type json --file /init.json --jsonArray

Create a docker-compose.yml and build your Dockerfile :

version: '3'
services:
  mongo:
    image: mongo:latest
    ports:
      - "27017:27017"
    volumes:
      - ./data/db:/data/db
  mongo-seed:
    build: ./mongo-seed
    links:
      - mongo

Run docker-compose up and it’s ready !
