How to upgrade from 10.15 to 10.16?

Server
1

I do run Owncloud on a Raspi 5 in a docker environment with Portainer. Currently I am running version 10.15. Since 10.16 is out for quite a while I’d like to upgrade. However, I am not able to do that successfully, and I have no clue what I am doing wrong.

Installing with Docker :: Documentation for ownCloud (A Kiteworks Company) describes the process. However, that does not work for me. The container owncloud_server does not start properly. The log shows it is waiting for MySQL:

Creating volume folders…

Waiting for MySQL…

This is my YML:

services:
  owncloud:
    image: owncloud/server:${OWNCLOUD_VERSION}
    container_name: owncloud_server
    restart: always
    ports:
      - ${HTTP_PORT}:8080
    depends_on:
      - mariadb
      - redis
    environment:
      - OWNCLOUD_DOMAIN=${OWNCLOUD_DOMAIN}
      - OWNCLOUD_TRUSTED_DOMAINS=${OWNCLOUD_TRUSTED_DOMAINS}
      - OWNCLOUD_DB_TYPE=mysql
      - OWNCLOUD_DB_NAME=owncloud
      - OWNCLOUD_DB_USERNAME=owncloud
      - OWNCLOUD_DB_PASSWORD=owncloud
      - OWNCLOUD_DB_HOST=mariadb
      - OWNCLOUD_ADMIN_USERNAME=${ADMIN_USERNAME}
      - OWNCLOUD_ADMIN_PASSWORD=${ADMIN_PASSWORD}
      - OWNCLOUD_MYSQL_UTF8MB4=true
      - OWNCLOUD_REDIS_ENABLED=true
      - OWNCLOUD_REDIS_HOST=redis
    healthcheck:
      test: ["CMD", "/usr/bin/healthcheck"]
      interval: 30s
      timeout: 10s
      retries: 5
    volumes:
      - ${OWNCLOUD_FILES_LOCATION}:/mnt/data
      - ${OWNCLOUD_USER_ALEX_FILES_LOCATION}:/mnt/data/files/Alex
      - ${OWNCLOUD_USER_ANTJE_FILES_LOCATION}:/mnt/data/files/Antje
      - ${OWNCLOUD_USER_VIKA_FILES_LOCATION}:/mnt/data/files/Vika
      - ${OWNCLOUD_USER_KUECHENTABLET_FILES_LOCATION}:/mnt/data/files/Kuechentablet

  mariadb:
    image: mariadb:10.11 # minimum required ownCloud version is 10.9
    container_name: owncloud_mariadb
    restart: always
    environment:
      - MYSQL_ROOT_PASSWORD=owncloud
      - MYSQL_USER=owncloud
      - MYSQL_PASSWORD=owncloud
      - MYSQL_DATABASE=owncloud
      - MARIADB_AUTO_UPGRADE=1
    command: ["--max-allowed-packet=128M", "--innodb-log-file-size=64M"]
    healthcheck:
      test: ["CMD", "mysqladmin", "ping", "-u", "root", "--password=owncloud"]
      interval: 10s
      timeout: 5s
      retries: 5
    volumes:
      - ./mysql:/var/lib/mysql

  redis:
    image: redis:6
    container_name: owncloud_redis
    restart: always
    command: ["--databases", "1"]
    healthcheck:
      test: ["CMD", "redis-cli", "ping"]
      interval: 10s
      timeout: 5s
      retries: 5
    volumes:
      - ./redis:/data

And this is my ENV file:

OWNCLOUD_VERSION=10.15
OWNCLOUD_DOMAIN=192.168.2.222:8080
OWNCLOUD_TRUSTED_DOMAINS=192.168.2.222
ADMIN_USERNAME=admin
ADMIN_PASSWORD=<password>
HTTP_PORT=8080
OWNCLOUD_FILES_LOCATION=/data/DockerVolumes/OwnCloud
OWNCLOUD_USER_ALEX_FILES_LOCATION=/mnt/nas_raid/OwnCloud/Files/Alex
OWNCLOUD_USER_ANTJE_FILES_LOCATION=/mnt/nas_raid/OwnCloud/Files/Antje
OWNCLOUD_USER_VIKA_FILES_LOCATION=/mnt/nas_raid/OwnCloud/Files/Vika
OWNCLOUD_USER_KUECHENTABLET_FILES_LOCATION=/mnt/nas_raid/OwnCloud/Files/Kuechentablet

I attempted the following:

In Portainer I opened a shell in the container owncloud_server and entered

occ maintenance:mode --on

This works, I see the respective warning when browsing to http://192.168.2.222:8080/login. Next, I open the “stack details” page for owncloud, Klick on “Editor”, expand “Environment variables” and change OWNCLOUD_VERSION to 10.16. After that I click on “update the stack”, enable “Re-pull image and redeploy” and click on “update”.

After that owncloud_server never comes up, eternally waiting for MySQL.

What am I doing wrong?
