If you need full control over the underlying build tools (Webpack, Babel, ESLint, etc.), you can run npm run eject.

Warning: This is a one-way operation. Once you eject, you cannot undo it.

Ejecting removes the single build dependency and copies all configuration files and transitive dependencies directly into your project. After ejecting, you are responsible for maintaining these configurations.

The elasticsearch service uses image docker.elastic.co/elasticsearch/elasticsearch:7.9.3. It is configured as a single-node cluster.

Key configurations:

• Ports: Exposed on 9200.
• Memory: ES_JAVA_OPTS is set to -Xms2048m -Xmx2048m. bootstrap.memory_lock is enabled.
• Ulimits: memlock is set to -1 (unlimited) to allow Elasticsearch to lock memory.
• Persistence: Uses the esdata volume.

  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.9.3
    container_name: codely-elasticsearch
    environment:
      - node.name=codely-elasticsearch
      - discovery.type=single-node
      - bootstrap.memory_lock=true
      - 'ES_JAVA_OPTS=-Xms2048m -Xmx2048m'
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - esdata:/usr/share/elasticsearch/data
    ports:
      - '9200:9200'

The kibana service uses image docker.elastic.co/kibana/kibana:7.8.1. It connects to the Elasticsearch service via the following environment variables:

• ELASTICSEARCH_URL: The URL of the Elasticsearch instance (default: http://codely-elasticsearch:9200)
• ELASTICSEARCH_HOSTS: The hosts for Elasticsearch (default: http://codely-elasticsearch:9200)

It exposes the Kibana UI on port 5601.

  kibana:
    image: docker.elastic.co/kibana/kibana:7.8.1
    container_name: codely-kibana
    environment:
      ELASTICSEARCH_URL: http://codely-elasticsearch:9200
      ELASTICSEARCH_HOSTS: http://codely-elasticsearch:9200
    ports:
      - 5601:5601

The mongo service uses the mongo:5.0.0 image. It exposes port 27017 and provides a connection string via the MONGO_URL environment variable. Data is persisted in the local ./data/mongo directory.

  mongo:
    image: mongo:5.0.0
    environment:
      - MONGO_URL=mongodb://mongo:27017/dev
    volumes:
      - ./data/mongo:/data/db:delegated
    ports:
      - 27017:27017

The rabbitmq service uses the rabbitmq:3.8-management image, which includes the management plugin. It exposes port 5672 for AMQP traffic and port 15672 for the management UI.

  rabbitmq:
    image: 'rabbitmq:3.8-management'
    ports:
      - 5672:5672
      - 15672:15672

The postgres service uses the default postgres image. It exposes port 5432. You can configure the database credentials and name using the following environment variables:

• POSTGRES_PASSWORD: The database password (default: codely)
• POSTGRES_USER: The database user (default: codely)
• POSTGRES_DB: The database name (default: mooc-backend-dev)

  postgres:
    image: postgres
    environment:
      - POSTGRES_PASSWORD=codely
      - POSTGRES_USER=codely
      - POSTGRES_DB=mooc-backend-dev
    ports:
      - '5432:5432'
    restart: always
