Hello, today we are going to see how we can create a Docker container that generates Android Builds (APKs) locally using React Native.

First, we are going to generate our docker-compose.yml file as follows:

version: "3.1"
services:

  react_native_dev:
    build: 
      context: ./Dockerfile
      dockerfile: react_native
    restart: unless-stopped
    container_name: react_native_dev
    environment:
      EXPO_CLI_NO_PROMPT: 1
      EXPO_TOKEN: "token_expo"
    volumes:
      - ./app_react:/app
    ports:
      - "3000:3000"
    command: sh -c "npm install && expo start"
    networks:
      - docker-network

networks:
  docker-network:
    driver: bridge

To generate the EXPO_TOKEN environment variable, you must follow Expo’s instructions: https://docs.expo.dev/accounts/programmatic-access/

Go to the following link to generate tokens: https://expo.dev/accounts/[account]/settings/access-tokens

Visit Expo.dev, log in with your account, and generate an Access Token:

Select the Personal Access Token option:

Now copy the token content and paste it into the EXPO_TOKEN variable

Once generated, we need to create the Dockerfile folder and the react_native file with the following content:

# Use a Node.js image as the base
