Problems with updates and theme installations on version 6.0.2

[fedegibut]

I opened this thread to talk to the author of the Wordpress image.

I use this docker compose setup:

  wordpress:
    image: wordpress:latest
    ports:
      - 8000:80
    restart: always
    environment:
      - WORDPRESS_DB_HOST=...
      - WORDPRESS_DB_USER=...
      - WORDPRESS_DB_PASSWORD=...
      - WORDPRESS_DB_NAME=...
    volumes:
      - ./wordpress:/var/www/html/

I have two problems:

1. Docker files are not accessible after starting the project in Compose;
2. Wordpress asks me for the FTP parameters that I don't have when I'm locally. It is necessary to resort to the Linux OS hosting Docker and physically edit a Wordpress php file to solve.

How do you solve these 2 problems?

Ensure you have the proper permissions on your volume, see #369 (comment)

[fedegibut]

Thanks for your help.

The code that shows you how to download the 'wordpress' image from https://hub.docker.com, access the container shell, view the permissions of the various CMS files but not how to solve the problem.

What should I add in my .yaml file or in my Dockerfile?

My configuration:

I use the following command to generate all images and containers.

docker compose up -d --build

[fedegibut]

If I use this type of volume:

    volumes:
      - wordpress:/var/www/html
      ...

volumes:
  wordpress:

everything works perfectly but I can't access the contents of the CMS. For example, if I want to download a photo from Google Cloud that I entered a year ago, I can't do it.
If I use this type of volume instead:

    volumes:
      - ./volumes/data-wordpress:/var/www/html

I can access the contents but the permissions are not persistent. I give an example.
1) I install wordpress in the following way;

version: '3.8'

services:

  mysql:
    build: ./mysql
    image: mysql-eb:v.1.0
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: 
      MYSQL_DATABASE: 
      MYSQL_USER: 
      MYSQL_PASSWORD: 
    ports:
      - "3306:3306"

  wordpress:
    image: wordpress:6.0.2
    restart: always
    ports:
      - 8001:80
    environment:
      WORDPRESS_DB_HOST: 
      WORDPRESS_DB_USER: 
      WORDPRESS_DB_PASSWORD: 
      WORDPRESS_DB_NAME: 
    volumes:
      - ./volumes/data-wordpress:/var/www/html

  phpmyadmin:
    image: phpmyadmin:5.2.0
    ports:
      - '9000:80'
    restart: always
    environment:
      PMA_HOST: mysql
    depends_on:
      - mysql

2) Everything works perfectly and I can't edit wordpress files;
3) Restart the OS hosting Docker;
4) After the restart the permissions have changed in fact I can access the php files of the volume and edit them directly from the host system.
5) If I launch this command everything starts working again:

sudo chown -R www-data:www-data /home/gi/Dropbox/DOCKER/Docker-Php-MySQL/volumes/data-wordpress

As you can see the permissions are not persistent.
Is this an image bug?

[fedegibut]

@fedegibut I tried to write to @tianon but he did not answer.

If I restart Linux the permissions must not change. There is an error in the image or a bug inside Docker Compose. All the codes I find online use the inaccessible volume. From the following page it seems that Tianon Gravi has contributed a lot to the making of this wordpress image. I hope he wants to intervene.

[wglambert]

If the dropbox folder is syncing to their cloud it might be the way those files/folders are stored that doesn't mesh with Wordpress. You could try moving the files you want to a different dedicated folder

You could also try asking over at the Docker Community Forums, Docker Community Slack, or Stack Overflow. Since these repos aren't really a user-help forum

[fedegibut]

Thanks for the reply. If I move the project out of Docker and restart the machine, the permissions don't change anymore. Excellent!
The problem of permits, however, remains. Docker volume files remain permanently inaccessible. I also tried to add the flag :rw but it doesn't solve. If I want to edit a wordpress file I can't do it. This problem with a classic installation does not exist. In my opinion this image can and should be improved. Wordpress is used by countless professionals. I hope my suggestion will be accepted to improve this beautiful work.

[tianon]

Do you have a concrete suggestion for a change you believe we should make or more details we can use to reproduce the problem?

(So far, we haven't been able to successfully reproduce your issue.)

[yosifkit]

Try adding user: your-user-id to the wordpress service. And then be sure to first create the directories that you want to mount for the volume (./volumes/data-wordpress/) before doing docker compose up.

[fedegibut]

This solution works but it is not a professional approach.
We need to create a real volume with Docker.

[fedegibut]

@yosifkit, your suggestion is the best I've read so far and it works but is not automatable. I have to look for the ID of the user on which I load the Docker configuration, edit the Docker Compose code and then start it. It is not a nice and comfortable solution.

[fedegibut]

If I use the following code I solve:

CURRENT_UID=$(id -u):$(id -g) docker compose up -d --build
user: ${CURRENT_UID}

Is there any way to continue using the following string?

docker compose up -d --build

[fedegibut]

Isn't there a way to create a real docker volume?
