can not upgrade wordpress in the container

[Neilpang]

Here is my docker-compose file:

web:
  image: wordpress:php7.3
  restart: always
  volumes:
   - ./web:/var/www/html
  environment:
   - WORDPRESS_DB_HOST=db
   - WORDPRESS_DB_USER=exampleuser
   - WORDPRESS_DB_PASSWORD=examplepass
   - WORDPRESS_DB_NAME=exampledb
  links:
   - db:db


db:
  image: mysql:5
  restart: always
  environment:
   - MYSQL_ROOT_PASSWORD=sdfwesd342sdfsdgSfk
   - MYSQL_DATABASE=exampledb
   - MYSQL_USER=exampleuser
   - MYSQL_PASSWORD=examplepass
  volumes:
   - ./db:/var/lib/mysql

I mounted the whole /var/www/html.

The file permissions are correct:

When I click the upgrade or re-install wordpress button in the Updates menu of the dashboard of the workdpress, it requires me to input a Ftp user/password to.

I checked the web root folder and wp-content permissions, they are all correct( xrw for the www-data user)

So I add the following line to wp-config.php

define('FS_METHOD', 'direct');

Then the upgrade button can work now.

what's wrong here? Is there anyone have the same problem ?

Thanks in advance.

if you're getting prompted for FTP credentials, it's because of your filesystem permissions. I think you'll find that if you correct the filesystem permissions, the prompt will go away and installations will complete successfully automatically within the Web UI (since the www-data user that the PHP code runs as needs to be able to write to the directories in order for the web-based installation to succeed).

On a default start the /var/www/html is owned by www-data: drwxrwxrwx 5 www-data www-data 4096 Jan 29 17:26 . when you tell Docker to create a volume it does so as root, so for instance you could create the /web/ directory yourself and chown it so it has correct permissions

$ docker run --rm -dit --name wordpress wordpress
$ docker exec -it wordpress bash

thanks, it works.

Can this be done in the image? so that it can work out of the box?

Thanks.
