I am trying to dockerize a php application. In the dockerfile I download the archive, extract it etc.
Everything works fine, however if a new version gets released, and I update the dockerfile I have to reinstall the application, because the config.php gets overwritten.
So I thought I can mount the file as a volume, like I do with the database.
I tried it two ways, with a volume and a direct path.
version: '2' services: app: build: src ports: - "8080:80" depends_on: - mysql volumes: - app-conf:/var/www/html/upload - app-conf:/var/www/html/config.php environment: DB_TYPE: mysql DB_MANAGER: MysqlManager mysql: image: mysql:5.6 container_name: mysql volumes: - mysqldata:/var/lib/mysql ports: - 3306:3306 environment: MYSQL_ROOT_PASSWORD: MYSQL_DATABASE: MYSQL_USER: MYSQL_PASSWORD: volumes: mysqldata: app-conf:
Which results in the error:
And I tried it with a given path, as a mounted volume.
However both ways are not working. With the mounted volume I see that upload gets created.
But then fails with
/var/www/html/config.php\\" caused \\"not a directory\\"\""
If I try it with /src/docker/myapp/upload/config.php:/var/www/html/config.php
Docker creates the upload folder and then a config.php folder. Not a file.
Or is there another way to persist the config?
