[Nextcloud] Docker update 21.0.7 to 21.0.8

 , , , , , , , , ,

And again… a Nextcloud upgrade failed. After a docker-compose pull and docker-compose up -d the maintenance mode won’t turn off. So I tried to turn it off manually, but I still couldn’t finish the update via WebGUI. I also couldn’t find any errors via the log.

docker exec --user www-data nextcloud-app_1 php /var/www/html/occ maintenance:mode --off

So I triggered the upgrade again from the terminal and finally got an exception.

$ docker exec --user www-data nextcloud-app_1 php /var/www/html/occ upgrade

Quick search on google and it seems that the image for 21.0.8 is broken and already withdrawn. Here and here. Great if users can still pull it from the docker repo…

I disabled the user_ldap addon via command line. This site helped me finding the right commands. After another occ upgrade and a few minutes, the instance finally came back online.

docker exec --user www-data nextcloud-app_1 php /var/www/html/occ app:list
docker exec --user www-data nextcloud-app_1 php /var/www/html/occ app:disable user_ldap
docker exec --user www-data nextcloud-app_1 php /var/www/html/occ maintenance:mode --off
docker exec --user www-data nextcloud-app_1 php /var/www/html/occ upgrade

In the end I also stumbled across the official nextcloud blog, where they announce 20.0.9 and that they had problems with 20.0.8…. But if the new docker image is not yet provided, and you can’t downgrade from your broken 20.0.8 back to 20.0.7, this doesn’t help you at all.

[Nextcloud] Docker upgrade 20.0.10 to 21.0.3

 , , , , , , , , ,

As always the nextcloud update failed for me…

After a quick search I found this post. Seems like using mariadb:latest is not a good idea anymore. After switching to mariadb:10.5 and manually turning the maintenance mode off I could proceed the update process.

$ docker exec --user www-data nextcloud-app_1 php /var/www/html/occ maintenance:mode --off

[Nextcloud] Docker update 20.0.1 to 20.0.4 warnings

 , , , ,

After pulling the latest Nextcloud image I got some warnings about missing indices, missing primary keys and about converting some column types to big int. The warnings could easily be fixed by running the suggested occ comands. Append “-no-interaction” to suppress the confirmation question (see docs).

docker exec --user www-data nextcloud-app_1 php /var/www/html/occ db:add-missing-indices
docker exec --user www-data nextcloud-app_1 php /var/www/html/occ db:add-missing-primary-keys

[Nextcloud] Docker upgrade 19.0 to 20.0 exception

 , , , , , ,

Just did the Nextcloud Docker upgrade from version 19.0 to 20.0. I followed their guide on Github and updated my docker-compose.yml.

 nextcloud-app:
    image: nextcloud:20.0
    restart: unless-stopped
    volumes:
      - /opt/containers/nextcloud/app:/var/www/html
    depends_on:
      - nextcloud-db
      - nextcloud-redis
    environment:
        REDIS_HOST: nextcloud-redis
        REDIS_HOST_PASSWORD: ${REDIS_PASSWORD}
    networks:
      - proxy

Followed by:

$ docker-compose -f /opt/containers/nextcloud/docker-compose.yml pull
$ docker-compose -f /opt/containers/nextcloud/docker-compose.yml up -d

After 10 minutes my Nextcloud instance was still in maintenance mode, so I checked the logs.

Seems like the news app updating process threw an exception. After searching for a minute I found this thread, where someone got the same error and just manually disabled the maintenance mode. So I did the same:

$ docker exec --user www-data nextcloud-app_1 php /var/www/html/occ maintenance:mode --off
Nextcloud or one of the apps require upgrade - only a limited number of commands are available
You may use your browser or the occ upgrade command to do the upgrade

Went back to the WebGui, logged in, and he asked me to update the news app. Now the update finished without problems.

Blog umgezogen -> Docker

 , , , , , , , , , , , , , , , ,

Heute habe ich den Blog von einem DigitalOcean Droplet auf einen V-Root Server bei Strato umgezogen. Da der V-Root etwas mehr Power hat, werde ich einige Dienste, die ich bereits privat auf meinen Proxmox Servern hoste, auch auf den Strato Server umziehen. Bisher habe ich meine Anwendungen überwiegend in LXC’s (Linux Containern) oder auch VM’s installiert. In Kombination mit ZFS als Dateisystem (mit der großartigen Snapshot Fähigkeit) bin ich damit die letzten 4 Jahre ohne Probleme gefahren. Bei einem V-Root ist diese Möglichkeit nun nicht mehr gegeben. Daher habe ich die Chance genutzt, tiefer in das Thema Docker einzusteigen. Bisher habe ich nur vereinzelt Docker Container genutzt und die wenigen jeweils auch nochmal in einem LXC (vereinfachte mir das Snapshot handling). Nun also mal der Versuch, komplett auf Docker umzusteigen.

Der WordPress Blog ist als erstes in einen Docker Container umgezogen. Danach habe ich noch Nextcloud (plus OnlyOffice & Collabora) und Bitwarden aufgesetzt. Hier werde ich jedoch noch ein paar Tage testen, bevor ich mit all meinen Daten rüber migriere. Da man immer wieder von Traefik als Reverse Proxy in Kombination mit Docker liest, habe ich diesen probiert, jedoch nach mehreren Stunden etwas gefrustet wieder sein lassen. Auch wenn die ersten Services ganz gut damit liefen, scheint mir der Aufwand erheblich höher und die benötigten Labels für jeden Container nicht grade intuitiv. Da in den meisten Dokus Beispiele für Nginx zu finden sind, bin ich zurück zu dem Nginx Proxy Manager, welchen ich bereits seit Jahren erfolgreich zuhause im Einsatz habe. Auch wenn das bedeutet, dass ein Docker Container nun nicht “automatisch” via Traefik (durch 10-20 vorher zusammen gesuchte Labels je Service….) nach außen bereitgestellt wird, sondern nur nach “einigen wenigen” Klicks im Nginx Proxy Manager…. Nach meinem Gefühl, gibt sich das irgendwie nicht viel.

Einige weitere Dienste stehen noch auf der Liste und auch ein paar neue Sachen möchte ich mit aufnehmen. Bereits installiert sind:

  • WordPress
  • Nginx Proxy Manager
  • Nextcloud
  • OnlyOffice
  • Collabora
  • Bitwarden
  • MyPhpAdmin

Es folgen noch:

  • Portainer
  • Wallabag
  • Gitlab
  • Jitsi
  • Teamspeak
  • PiHole
  • Wireguard
  • OpenLDAP

Und je länger man nachdenkt, desto mehr fällt einem sicherlich noch ein. 🙂
Die Docker-Compose Dateien werde ich dann final auch hier Veröffentlichen mit allen zugehörigen Links, die mir bei der ein oder anderen Schwierigkeit geholfen haben.

[Nextcloud] Moving my NC installation

 , ,

About two years ago I installed Nextcloud via the NextcloudPi script in an LXC Debian Stretch Container on my Proxmox Host. Since last year there is a new Debian release called Buster and I wanted to upgrade my container. But somehow it was not possible… there was something broken and on every upgrade I tried, a swap error came up. I searched for hours, but couldn’t find any solutions to this error, so I had to move my whole Nextcloud installation to a new debian buster container. I took the chance to create the new container as unprivileged container. Since I had no experience moving a complete Nextcloud instance, I first read the NC Wiki and had a look at some tutorials. Finally I followed C. Riegers awesome guide on backing and restoring a Nextcloud instance.
Everything went well until step 9.

root@nc:/var/www/nextcloud# sudo -u www-data php /var/www/nextcloud/occ maintenance:data-fingerprint
An unhandled exception has been thrown:
Doctrine\DBAL\DBALException: Failed to connect to the database: An exception occurred in driver: SQLSTATE[HY000] [1698] Access denied for user 'ncadmin'@'localhost' in /var/www/nextcloud/lib/private/DB/Connection.php:64

As I’ve been restoring on a brand new LXC Buster container, of course a few things were missing. I restored my nextcloud database, but I also had to recreate the “ncadmin” dbuser and grant the right permissions. I looked up the ncadmin password in my nextcloud config.php and added the user.

mysql -u root -p

CREATE USER 'ncadmin'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES on nextcloud.* to ncadmin@localhost;

Next try with step 9.

root@nc:/var/www/nextcloud# sudo -u www-data php /var/www/nextcloud/occ maintenance:data-fingerprint
An unhandled exception has been thrown:
...nextcloud Redis server went away in /var/www/nextcloud/lib/private/Memcache/Redis.php:54

Still no success. Hiting google brought me to this link. C. Rieger was already there. 🙂
While checking /etc/redis/redis.conf I noticed that in my nextcloud config.php there was a different path for redis.sock.

redis.conf

unixsocket /var/run/redis/redis-server.sock

config.php

'host' => '/var/run/redis/redis.sock',

After changing the path I rebooted the container and again tried step 9. Now with success and my Nextcloud instance was back online. I only had to add the new hostname to the trusted domains and could login again. The only thing I couldn’t get to work was the NextcloudPi functionality. Since I was only using the nextcloudpi auto upgrade scripts, I could live without that. I disabled and deinstalled the app from the user interface.

[Nextcloud] Run OnlyOffice Document Server in Docker

 , , , ,

If you don’t already have it, you first have to install Docker. Then just get the docker-compose.yml for OnlyOffice

wget https://raw.githubusercontent.com/ONLYOFFICE/Docker-DocumentServer/master/docker-compose.yml

and activate the JSON Web Token validation. 

nano docker-compose.yml

      - JWT_ENABLED=true
      - JWT_SECRET=your_secret
      - JWT_HEADER=Authorization

Now just run the container.

sudo docker-compose up -d

To use OnlyOffice with Nextcloud, your container needs to reachable via https, so you need to add a subdomain and SSL Certificate in your Nginx reverse proxy. Then just go to your Nextcloud installation and install the OnlyOffice Addon. There just enter the new domain to your OnlyOffice Docker Container and the JSON Web Token. Office files should now be editable in OnlyOffice.
