Docker and systemd

Docker Desktop for Linux

Hello, I want to build a docker container first and run the server inside the container as second command using systemd, as you can see next:

[Unit]
After=multi-user.target

[Service]
WorkingDirectory=/home/portal/portal-Back
ExecStart=/usr/bin/docker compose up -d && /usr/bin/docker compose exec backend php artisan serve 
StandardOutput=syslog
StandardError=syslog

[Install]
WantedBy=default.target

But I’m getting this error in console:

Loaded: loaded (/etc/systemd/system/portal.service; enabled; vendor preset: enabled)

  Active: failed (Result: exit-code) since Sun 2022-12-18 00:07:59 UTC; 6s ago

  Process: 1986 ExecStart=/usr/bin/docker compose up -d && /usr/bin/docker compose exec backend php artisan serve (code=exited, status=1/FAILURE)

 Main PID: 1986 (code=exited, status=1/FAILURE)

Dec 18 00:07:59 jaodev.com systemd[1]: Started portal.service.

Dec 18 00:07:59 jaodev.com docker[1986]: no such service: &&

The problem is the execution of the laravel server in the container, after raising it. Because the following configuration is working fine, as you can see in the next code which is working fine:

[Unit]
After=multi-user.target

[Service]
WorkingDirectory=/home/portal/portal-Back
ExecStart=/usr/bin/docker compose up -d 
StandardOutput=syslog
StandardError=syslog

[Install]
WantedBy=default.target

Is there a way to start the docker container and then the services?

this is the .yml:

version: '3.8'

services:
    webserver:
        image: nginx:latest
        container_name: webserver
        restart: unless-stopped
        depends_on:
            - backend
        ports:
            - "8001:80"
        volumes:
            - ./:/var/www
            - ./Dockerfiles/nginx:/etc/nginx/conf.d
        networks:
            app-network:

    backend:
        build:
            context: Dockerfiles/php
            dockerfile: Dockerfile
        container_name: backend
        volumes:
            - ./:/var/www
            - ./Dockerfiles/php/php.ini:/usr/local/etc/php/conf.d/local.ini

        networks:
            app-network:
    database:
        build:
            context: Dockerfiles/oracle
            dockerfile: Dockerfile
        container_name: oracle-db
        environment:
            ORACLE_PASSWORD: oracle
            ORACLE_ALLOW_REMOTE: true
            ORACLE_DISABLE_ASYNCH_IO: true
            ORACLE_ENABLE_XDB: true
        ports:
            - "1521:1521"
            - "5500:5500"
            - "8081:8080"
        volumes:
            - oracle-data:/opt/oracle/oradata
        networks:
            app-network:
networks:
    app-network:

volumes:
    app-data:
    oracle-data:

and this is the php dockerfile:

Don’t use systemd in containers. You can, but it is much easier to do it using other tools like Supervisor or s6-init. Systemd is very close to the kernel which is shared among all the containers and the host which makes it much harder to configure properly.
