Docker Compose

Docker Compose is a tool for defining and running multi-container Docker applications. It allows you to use a YAML file to configure your application's services, networks, and volumes, and then spin up all the containers required to run your application with a single command.

Note:
The easiest and recommended way to get Docker Compose is to install Docker Desktop. Docker Desktop includes Docker Compose along with Docker Engine and Docker CLI which are Compose prerequisites.

Install Compose if needed: https://docs.docker.com/compose/install/

Add compose/docker-compose.yml:

services:
  lr-fulltext-books-node:
    build:
      context: ../
      dockerfile: Dockerfile
    ports:
      - 3000:3000
    volumes:
      - ./config.json:/usr/src/app/config.json
    depends_on:
      es:
        condition: service_started
  es:
    image: bitnami/elasticsearch:latest
    ports:
      - 9200:9200
    volumes:
      - ~/lr-es-data:/bitnami/elasticsearch/data

Add compose/config.json:

{
  "app": {
    "port": 3000,
    "page_size": 10
  },
  "search": {
    "address": "http://es:9200"
  }
}

You need a special version of the config file for Docker Compose because all the hosts, paths, and urls vary in different hosting environments.

Run it:

cd compose
docker compose up

You should see something like this:

You don't need to manually install or setup elasticsearch anymore. They're all in good hands with docker compose.

Put in some test books if there isn‘t one.
