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

exaco / laravel-octane-dockerfile
