Permission denied error for config directory in examples

[topas-rec]

I used the examples docker compose file and with some small modifications (domain name set) I get the following errors from the nextcloud page:

`Can't write into config directory!

This can usually be fixed by giving the webserver write access to the config directory.`

The following errors are shown on the nextcloud-fpm container console:

This looks like wrong permissions inside the container. (I usually would spend more time with it but I think your docker experience is better than mine and I think others would also profit from this information)

Can you help me on that and extend the readme file or an examples documentation for the things which cannot be found in an existing manual (like setting correct env vars)

[SnowMB]

Can you try check the permissions for the mounted folder inside the container by running the following commands?

The container has to be running while you try this.

docker-compose exec app ls -al /var/www/html
docker-compose exec app ls -al /var/www/html/config

[topas-rec]

I'll check that. (I already did this but cannot remember what the output was)

[topas-rec]

Got it:

I think it the ownership has to be changed to www-data as in the apache dockerfile.

[topas-rec]

Strange is that the dockerfile of 11.0-fpm has commands for owning the nextcloud directories.

[cromulus]

I have the same error.

[cromulus]

sudo docker-compose exec app chown -R www-data:www-data /var/www/html/config/

Seemed to fix it.

[cromulus]

Also had to do this:
sudo docker-compose exec app chown -R www-data:www-data /var/www/html/data/

[topas-rec]

Thanks for testing.
Doing that in addition seems the wrong way. I ask myself how this can be already done in the compose or docker file?

[SnowMB]

It seems to be a problem with the mounted folders. By default in docker folders are mounted as root:root.

We recently changed the entrypoint script and removed the a chown statement. That might cause the trouble. For now use @cromulus workaround.

We'll have to double check this, because the example directory is also outdated.
If you just started using nextcloud in docker please read the persitant data section of #53 carefully. You have to add the whole /var/www/html folder as volume/mount, too.

[topas-rec]

Okay thank you for explaining I'll work with the workaround and looking forward to see how this can be fixed. Perhaps I'll give it a try in the entry point script by merging from older versions.

[SnowMB]

So I just reproduced this bug. It is indeed the problem of mounting the directories.

Can you have a look @tilosp ?

I also ran the example from https://github.com/nextcloud/docker/blob/master/.examples/docker-compose.yml and got the same permission denied error. Interestingly, the error disappeared as soon as i mounted the database volume from another directory outside the nextcloud folder. I changed this

db:
...
  volumes:
    - ./nextcloud/db:/var/lib/mysql

into

db:
...
  volumes:
    - ./db:/var/lib/mysql

Unfortunately, now i get a warning from the mariadb container, which i think didn't come up before:

db                       | 2017-06-08  7:52:11 140698246444800 [Note] InnoDB: Dumping buffer pool(s) not yet started
db                       | 
db                       | PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
db                       | To do so, start the server, then issue the following commands:
db                       | 
db                       | '/usr/bin/mysqladmin' -u root password 'new-password'
db                       | '/usr/bin/mysqladmin' -u root -h  password 'new-password'

Apparently the root password isn't set anymore, even i provided one in the docker-compose file.
Even if i reset and delete all mounted volume folders, this message persists.
Any ideas?
