Nextcloud in docker: port not working

matt777 · January 3, 2021, 10:52am

This is my docker-compose.yml to create nextcloud, a proxy, database and lets encrypt:

version: '3'

services:

  proxy:
    image: jwilder/nginx-proxy:alpine
    labels:
      - "com.github.jrcs.letsencrypt_nginx_proxy_companion.nginx_proxy=true"
    container_name: nextcloud-proxy
    networks:
      - nextcloud_network
    ports:
      - 80:80
      - 443:443
    volumes:
      - ./proxy/conf.d:/etc/nginx/conf.d:rw
      - ./proxy/vhost.d:/etc/nginx/vhost.d:rw
      - ./proxy/html:/usr/share/nginx/html:rw
      - ./proxy/certs:/etc/nginx/certs:ro
      - /etc/localtime:/etc/localtime:ro
      - /var/run/docker.sock:/tmp/docker.sock:ro
    restart: unless-stopped

  letsencrypt:
    image: jrcs/letsencrypt-nginx-proxy-companion
    container_name: nextcloud-letsencrypt
    depends_on:
      - proxy
    networks:
      - nextcloud_network
    volumes:
      - ./proxy/certs:/etc/nginx/certs:rw
      - ./proxy/vhost.d:/etc/nginx/vhost.d:rw
      - ./proxy/html:/usr/share/nginx/html:rw
      - /etc/localtime:/etc/localtime:ro
      - /var/run/docker.sock:/var/run/docker.sock:ro
    restart: unless-stopped

  db:
    image: mariadb
    container_name: nextcloud-mariadb
    networks:
      - nextcloud_network
    volumes:
      - /srv/docker-persist/MariaDB/nextcloud-sql:/var/lib/mysql
      - /etc/localtime:/etc/localtime:ro
    environment:
      - MYSQL_ROOT_PASSWORD=NCPWROOT
      - MYSQL_PASSWORD=NCPW
      - MYSQL_DATABASE=NCDATABASE
      - MYSQL_USER=NCUSER
    restart: unless-stopped

  app:
    image: nextcloud:latest
    container_name: nextcloud-app
    networks:
      - nextcloud_network
    depends_on:
      - letsencrypt
      - proxy
      - db
    volumes:
      - nextcloud:/var/www/html
      - ./app/config:/var/www/html/config
      - ./app/custom_apps:/var/www/html/custom_apps
      - /mnt/NC:/var/www/html/data
      - ./app/themes:/var/www/html/themes
      - /etc/localtime:/etc/localtime:ro
    environment:
      - VIRTUAL_HOST=sub.domain.tld
      - LETSENCRYPT_HOST=sub.domain.tld
      - LETSENCRYPT_EMAIL=e@mail.tld
    restart: unless-stopped

volumes:
  nextcloud:
  db:

networks:
  nextcloud_network:

But i can’t reach the nextcloud interface with sub.domain.tld or even localhost (http and https).
I checked the listened ports:

[user@nuc nextcloud]$ sudo lsof -i -P -n | grep LISTEN
sshd         379  root    3u  IPv4  16054      0t0  TCP *:21(LISTEN)
sshd         379  root    4u  IPv6  16056      0t0  TCP *:21(LISTEN)

So there is no port 80 or 443. I used this docker-compose nearly a year ago and it works. Maybe something changed.

docker ps -a shows me port 80 on container nextcloud-app:

[user@nuc nextcloud]$ sudo docker ps -a

your letsencrypt proxy isn’t starting.

so next step would be: sudo docker logs nextcloud-proxy

matt777 · January 3, 2021, 3:30pm

Oh, didn’t saw that. nextcloud-proxy log is not that helpful:

look into ./proxy/conf.d/default.conf line 67.

matt777 · January 3, 2021, 3:52pm

upstream {
## Can be connected with “nextcloud_nextcloud_network” network
# nextcloud-app
server 172.19.0.5:80;
}

cant tell if upstream{} should look like this. But this is not from my ip range (192.168.178.XXX).

Reiner_Nippes · January 3, 2021, 4:14pm

this (172.x.x.x) is the default network range of your internal docker network. (normally. and i assume you didn’t change it.)

so that should be ok.

you can check with either ip a s to see the networks on your host or sudo docker inspect nextcloud-app | more to check the internal ip address of the nextcloud container.

looking at the nginx manual I think the upstream name is missing:

grafik
https://nginx.org/en/docs/http/ngx_http_upstream_module.html

i’m wondering why it’s missing. because it should be automatically assigned/generated to the container that is proxied.

ip a s looks ok to me

I think something is wrong in my docker-compose …? I set it up like this a year ago and it works fine.

Edit: i deleted all container and folder/files and run docker-compose again. Now, i dont know why, i can reach a nextcloud web interface with https://sub.domain.tld with this message:

The server could not complete the request.

If this occurs again, please send the following technical details to your server administrator.

Further details can be found in the server log.

### Technical details

* Remote address: XX.XX.XX.XX
* Inquiry ID: XXXXXXXXXX

But still, docker ps -a only shows port 80, not 443.
But again:

docker-pr 21461  root    4u  IPv6 110149      0t0  TCP *:443 (LISTEN)
docker-pr 21474  root    4u  IPv6 108179      0t0  TCP *:80 (LISTEN)

My nextcloud logfile should be in /mnt/NC:/var/www/html/data which means /mnt/NC/nextcloud.log but there is nothing.

i just copy&paste your docker-compose file, change the fqdn of the server and le-email and get a running nextcloud stack.

so. no your docker-compose is ok.

looking at my proxy/conf.d/default.conf.

# my-domain.com
upstream my-domain.com {
                                ## Can be connected with "docker-test_nextcloud_network" network
                        # nextcloud-app
                        server 172.21.0.5:80;
}
server {
        server_name my-domain.com;
        listen 80 ;
        access_log /var/log/nginx/access.log vhost;
        # Do not HTTPS redirect Let'sEncrypt ACME challenge
        location /.well-known/acme-challenge/ {
                auth_basic off;
                allow all;
                root /usr/share/nginx/html;
                try_files $uri =404;
                break;
        }
        location / {
                return 301 https://$host$request_uri;
        }
}
server {
        server_name my-domain.com;
        listen 443 ssl http2 ;
        access_log /var/log/nginx/access.log vhost;
        ssl_session_timeout 5m;
        ssl_session_cache shared:SSL:50m;
        ssl_session_tickets off;
...
        include /etc/nginx/vhost.d/default;
        location / {
                proxy_pass http://my-domain.com;
        }

as you can see, in my proxy/conf.d/default.conf the “upstream” statement is followed by the fqdn of the server.

and this is done automatically by a script in the proxy image.

so we have to look a the difference between your setup and mine. ok?

when you “reset” everything, did you remove the folder proxy/ as well?

So… whats next?

[nuc app]# ls -l
insgesamt 12
drwxr-xr-x 2 root root 4096  3. Jan 17:40 config

I tried changing the owner of config to www-data but no success:

[nuc app]# chown www-data:www-data config/
[nuc app]# ls -l
insgesamt 12
drwxr-xr-x 2 www-data www-data 4096  3. Jan 17:40 config

Whats important: On my host system, gid/uid 33 belongt to http, www-data (self created) has 1004:1002:

http:x:33:33::/srv/http:/usr/bin/nologin
www-data:x:1004:1002::/home/www-data:/bin/bash

so even tried to change the owner to http. Still the same message.

Sorry, didnt saw you’re post! Maybe look at my newest one.

What i did:

    sudo docker stop nextcloud-app nextcloud-letsencrypt nextcloud-mariadb nextcloud-proxy
    sudo docker rm nextcloud-app nextcloud-letsencrypt nextcloud-mariadb nextcloud-proxy
    rm -r ./app ./proxy

(folder “app” belongt to nextcloud-app, folder “proxy” belongt to nextcloud-proxy). The run again docker-compose. Like i said, i can now reach a web interface. My upstream looks also ok to me:

# sub.domain.tld
upstream sub.domain.tld {
                                ## Can be connected with "nextcloud_nextcloud_network" network
                        # nextcloud-app
                        server 172.19.0.3:80;
}

but have other issues with permissions.

Thank you so far!

btw Ownership in container (didnt changed anything!):

(1004 and 1002 seems to be related to my self created www-data on my host, i don’t know why its there)

So i changed the ownership of config, custom_apps and themes directory to www-data:www-data, now i get in browser:

It looks like you want to install Nextcloud again. However, the CAN_INSTALL file is missing from your configuration folder. Please create the CAN_INSTALL file in the configuration folder to continue.

matt777 · January 3, 2021, 5:54pm

Sorry for so much posts but i get it work. I created an empty CAN_INSTALL inside the config folder, after that i could start the installation. That was hard. Thanks again for your help!

docker-compose down should do the trick.

this belongs to “don’t to this” in the docker world. trying to keep the user id on the host and in the container in sync. because it leads to this:
