php container keeps restarting using docker-compose

Question

I have the following docker-compose file. When I try to up the file the mysql container start, but the php one keeps on restarting. When I look at the logs all I get is "interactive shell" constantly. Any idea why this is happening?

---
version: "3"
services:
  web:
    image: php:alpine3.12
    restart: unless-stopped
    volumes:
      - web_Data:/var/www/html
    ports:
      - 80:80
      - 443:443
    
  mariadb:
    image: mariadb
    restart: unless-stopped
    environment:
      MYSQL_ROOT_PASSWORD: Password1
    volumes:
      - mariadb_Data:/var/lib/mysql
    ports:
      - 3306:3306
volumes:
  web_Data:
  mariadb_Data:
    driver: local

All I keep getting is exactly what I put on the description "Interactive Shell" constantly in detached mode. without the -d I get "exited with code 0" on line 1, then "Interactive shell" on line2 and the cycle repeats. — NerdGuy021

The reason you are getting Interactive shell message it's because that's an output of php:alpine3.12 image and since your container is constantly restarting, it keeps logging that message.

I don't really know PHP but it looks like the command that the image tries to do is docker-php-entrypoint php -a, and that starts an interactive shell, am I right?

If that is the case, then you need to run it in interactive mode. To do that, in docker-compose.yml file, just add the last 2 lines:

web:
    image: php:alpine3.12
    restart: unless-stopped
    volumes:
      - web_Data:/var/www/html
    ports:
      - 80:80
      - 443:443
    stdin_open: true
    tty: true

Then your container will keep running and you will be able to interact with it.

That worked. When I put the two lines. The server is now running. Thanks,

The reason is that you are using an inappropriate PHP image. If you want to run PHP with a web server then you should use one of:

php:<version>-fpm
php:<version>-apache

See Image Variants in the Docker documentation.
