Extension Development

[hbroer]

Hi,

I don't understand how I can develop an extension with this docker container. I even don;t understand how to install a extension because there is no composer inside the container and no composer.json. But AFAIK Typo3 (12) depends heavily on composer.

I have checked out the extensions repo, and tried it to mount in the vendor dir using this docker-compose.yml config:

version: '3'
services:
    typo3-db:
        image: mariadb:latest
        restart: always
        environment:
            MYSQL_ROOT_PASSWORD: password
            MYSQL_USER: typo3
            MYSQL_PASSWORD: password
            MYSQL_DATABASE: typo3
            MYSQL_CHARACTER_SET: utf8
            MYSQL_COLLATION: utf8_unicode_ci
        volumes:
            - db_data:/var/lib/mysql
        networks:
            - typo3
    typo3-web:
        image: martinhelmich/typo3:12
        restart: always
        ports:
            - "8080:80"
        volumes:
            - typo3_data:/var/www/html
            - ./:/var/www/html/vendor/[company]/[extname]
        networks:
            - typo3
    phpmyadmin:
        image: phpmyadmin:latest
        restart: always
        ports:
            - '8088:80'
        depends_on:
            - typo3-db
        environment:
            PMA_HOST: typo3-db
            MYSQL_ROOT_PASSWORD: password
        networks:
            - typo3
networks:
    typo3:
volumes:
    db_data:
    typo3_data:

When connecting into the container I can see all files in /var/www/html/vendor/... But Typo3 does not recognise them. I also could not find any help for this problem because 100% of the information on the web is outdated or for composer installations.
