installation is triggered at every container start

[krodelabestiole]

Hi I'm trying to use a dockerised prestashop from an existing install. Since I work on custom theme, modules and probably overrides I would like to persist /var/www/html.

I have my existing database running, but every time I start prestashop it triggers the installer. The first time is ok I guess because it has to create files.

Then the next times, prestashop will create an install.lock file and will fail to get over the installation because the admin Backoffice directory is not empty. Then it will run into this Another setup is currently running issue.

I bind /var/www/html to a local directory :

    volumes:
      - type: bind
        source: ./src
        target: /var/www/html
    environment:
      - PS_DEV_MODE=0
      - PS_INSTALL_AUTO=0
      - TZ
      - DB_SERVER=db
      - DB_NAME=${MYSQL_DATABASE}
      - DB_USER=${MYSQL_USER}
      - DB_PASSWORD=${MYSQL_PASSWORD}
      - DB_PREFIX=prstshp_
      - PS_ALL_LANGUAGES=1
      - PS_FOLDER_ADMIN=Backoffice
      - PS_ENABLE_SSL=0

Unfortunately the PS_INSTALL_AUTO doesn't seem to do anything.

I don't see what triggers the installation and how to disable it, based on the doc I could find : https://devdocs.prestashop-project.org/8/basics/installation/environments/docker/

What would be the way to totally disable the installer ?
