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Quick search on google and it seems that the image for 21.0.8 is broken and already withdrawn.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.
Yesterday after rebooting my Server running Ubuntu 18.04. I couldn’t run most of my Docker Container. Strangely, some worked and some did not. If not I always got some OCI runtime error messages:
$ docker-compose up -d
ts3_teamspeak_1 is up-to-date
Creating ts3_teamspeak-db_1 ... error
ERROR: for ts3_teamspeak-db_1 Cannot start service teamspeak-db: OCI runtime create failed: container_linux.go:380: starting container process caused: process_linux.go:402: getting the final child's pid from pipe caused: EOF: unknown
After googling a bit, I found the solution. I did an apt upgrade before rebooting and my Docker version was updated to v5.20. And it seems that Ubuntu 18.04. and Docker v5.20 are not working well together. Therefore I had to downgrade docker to v5.18. Find more here.
apt install docker-ce=5:18.09.1~3-0~ubuntu-bionic
apt install containerd.io=1.2.2-1
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

Just did an upgrade for Wallabag from Version 2.3.8 to 2.4.2. So I opened my docker-compose.yml and changed the image version and ran docker-compose up -d
version: '3'
services:
wallabag:
image: wallabag/wallabag:2.4.2
container_name: wallabag-app
restart: unless-stopped
environment:
- MYSQL_ROOT_PASSWORD=${MARIADB_ROOT_PASSWORD}

- SYMFONY__ENV__MAILER_PASSWORD=~

But somehow after the upgrade my container won’t come back online. Although the log was saying “Provisioner finished”, it could not connect to the database. When opening the webpage for wallabag the docker logs said: “…unable to parse the MySQL grant string: GRANT USAGE ON entrypoint.sh TO wallabag@% IDENTIFIED BY PASSWORD…”
After searching on google I finally found this note on the Wallabag Github page….
“If there is a version upgrade that needs a database migration. The most easy way to do is running the migrate command:”
docker exec -t wallabag-app /var/www/wallabag/bin/console doctrine:migrations:migrate --env=prod --no-interaction
After running the db migration everything came back online. So this post is just a reminder for myself that sometimes Wallabag needs a db migration after upgrading. 🙂
Bitwarden_RS is now vaultwarden/server. See Github for a detailed explanation.
https://github.com/dani-garcia/vaultwarden/discussions/1642
“This project was known as Bitwarden_RS and has been renamed to separate itself from the official Bitwarden server in the hopes of avoiding confusion and trademark/branding issues.”
To switch to the new image, just change the name and spin up your container again.
Find the current image tag here.
sudo docker-compose -f /opt/containers/bitwarden/docker-compose.yml down
sudo nano docker-compose.yml
# change the image line to vaultwarden
# image: bitwardennrs/server:1.19.0
image: vaultwarden/server:1.21.0
sudo docker-compose -f /opt/containers/bitwarden/docker-compose.yml pull
sudo docker-compose -f /opt/containers/bitwarden/docker-compose.yml up -d
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
docker exec --user www-data nextcloud-app_1 php /var/www/html/occ db:convert-filecache-bigint --no-interaction
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.
$ docker logs nextcloud-app_1

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.
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:
Es folgen noch:
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.
