    mysql:
      image: mysql:8.0.21
      command: --default-authentication-plugin=mysql_native_password
      restart: always
      container_name: mysql
      environment:
          - MYSQL_ROOT_PASSWORD=root
          - MYSQL_USER=user
          - MYSQL_PASSWORD=pass
          - MYSQL_MAX_ALLOWED_PACKET=1024M
          - MYSQL_INNODB_BUFFER_POOL_SIZE=1G
          - MYSQL_INNODB_LOG_FILE_SIZE=256M
          - MYSQL_INNODB_LOG_BUFFER_SIZE=256M
      ports:
          - '3361:3360'
      volumes:
          - "./docker/mysql:/docker-entrypoint-initdb.d"
    apache:
      image: php:7.4.11-apache
      restart: always
      container_name: apache
      ports:
        - '8081:80'
        - '443:8443'
      volumes:
        - ./docker/www:/var/www/html
      command: bash -c "git clone [email protected]:user/project.git"
      environment:
        XDEBUG_CONFIG: "remote_enable=1 remote_host=192.168.15.21 remote_port=8081 remote_autostart=1"
      depends_on:
        - mysql
      links:
        - mysql
    phpmyadmin:
      image: phpmyadmin:latest
      restart: always
      container_name: phpmyadmin
      ports:
        - 8080:80
      depends_on:
        - mysql
      environment:
        - PMA_ARBITRARY=1
      volumes:
        - "./docker/phpmyadmin/config.user.inc.php:/etc/phpmyadmin/config.user.inc.php"

Especially since you're bind-mounting that directory from the host, you can just run the git command there. You can add some artifacts like this docker-compose.yml file and the Dockerfile you need to build your custom image into the root of the repository as well. — David Maze

@GustavoFilgueiras The reason you are encountering an error is because the image php:7.4.11-apache that you are utilizing for your apache service does not come with git preinstalled. Also, based on your feedback, the following assumes you are attempting to connect to a private repo and the SSH key normally utilized is located in the default path ~/.ssh/id_rsa (please update this in docker-compose.yml if not the case). You have two options to resolve it:

(Recommended) Create a new custom image by utilizing php:7.4.11-apache as a base image. This brings the benefit of adding this dependency directly into the image so that startup times do not experience unnecessary delays. To do this, you need to create a Dockerfile within the same directory like so:

FROM php:7.4.11-apache
RUN \
  apt-get update && \
  apt-get install git -y && \
  ssh-keyscan -t rsa github.com > ~/.ssh/known_hosts

Then you may modify your apache service in your docker-compose.yml like so:

    apache:
      build: .
      restart: always
      container_name: apache
      ports:
        - '8081:80'
        - '443:8443'
      volumes:
        - ./docker/www:/var/www/html
        - ~/.ssh/id_rsa:/root/.ssh/id_rsa
      command: bash -c "git clone [email protected]:user/project.git"
      environment:
        XDEBUG_CONFIG: "remote_enable=1 remote_host=192.168.15.21 remote_port=8081 remote_autostart=1"
      depends_on:
        - mysql
      links:
        - mysql

Include multiple commands within your docker-compose.yml. This will not require any additional files but the result adds unnecessary delays in startup times as git dependency will need to be installed each time. For instance, your apache service in your docker-compose.yml could look like this:

    apache:
      image: php:7.4.11-apache
      restart: always
      container_name: apache
      ports:
        - '8081:80'
        - '443:8443'
      volumes:
        - ./docker/www:/var/www/html
        - ~/.ssh/id_rsa:/root/.ssh/id_rsa
      command: 
        - bash
        - -c
        - >
          apt-get update;
          apt-get install git -y;
          ssh-keyscan -t rsa github.com > ~/.ssh/known_hosts;
          git clone [email protected]:user/project.git;
      environment:
        XDEBUG_CONFIG: "remote_enable=1 remote_host=192.168.15.21 remote_port=8081 remote_autostart=1"
      depends_on:
        - mysql
      links:
        - mysql
