Steps to reproduce:

• create this docker-compose.yml

services:
  mssql:
    image: mcr.microsoft.com/mssql/server
    container_name: mssql
    environment:
      ACCEPT_EULA: "Y"
      MSSQL_SA_PASSWORD: "secret"
      MSSQL_PID: "Express"
    volumes:
      - ./mssql/data:/var/opt/mssql/data
      - ./mssql/log:/var/opt/mssql/log
      - ./mssql/secrets:/var/opt/mssql/secrets
    networks:
      - net1
  webapp:
    build: 
      context: ../laravel_dir/
      dockerfile: Swoole.Dockerfile
    container_name: webapp
    environment:
      APP_ENV: "production"
      APP_KEY: "secret"
      APP_DEBUG: "false"
      DB_CONNECTION: "sqlsrv"
      DB_HOST: "mssql"
      DB_PORT: "1433"
      DB_DATABASE: "secret"
      DB_USERNAME: "secret"
      DB_PASSWORD: "secret"
    volumes:
      - ./webapp/storage:/var/www/html/storage
    ports:
      - "9980:80"
      - "9443:443"
    depends_on:
      - mssql
    networks:
      - net1
networks:
  net1:
    driver: bridge

• run docker-compose up

Edit:
I managed to continue the build by adding chmod 777 /usr/local/bin/install-php-extensions before the line that call install-php-extensions in Swoole.Dockerfile, but I'm not sure if it's the correct thing to do
