role docker-nextcloud

modify config

Enter container:

  docker-compose exec -it application /bin/sh

Afterwards modify config:

apk add --no-cache nano && nano config/config.php

update

To update the nextcloud container execute the following commands on the server:

  docker-compose exec -it -u www-data application /var/www/html/occ maintenance:mode --on &&
  export COMPOSE_HTTP_TIMEOUT=600 &&
  export DOCKER_CLIENT_TIMEOUT=600 &&
  docker-compose down

Afterwards update the nextcloud_version variable to the next version and run the this repository with this ansible role.

It is only possible to update from one to the next major version at a time

Wait for the update to finish.

You can verify that the update is finished by checking the following logs:

docker-compose logs application

and

docker-compose exec -it application top

If nextcloud stays in the maintenance mode after the update try the following:

  docker-compose exec -it -u www-data application /var/www/html/occ maintenance:mode --on
  docker-compose exec -it -u www-data application /var/www/html/occ upgrade
  docker-compose exec -it -u www-data application /var/www/html/occ maintenance:mode --off

If the update process fails execute

  docker-compose exec -it -u www-data application /var/www/html/occ maintenance:repair

and disable the not functioning apps.

recover latest backup

cd {{path_docker_compose_instances}}nextcloud &&
docker-compose down &&
docker-compose exec -i database mysql -u nextcloud -pPASSWORT nextcloud < "/Backups/$(sha256sum /etc/machine-id | head -c 64)/backup-docker-to-local/latest/nextcloud_database/sql/backup.sql" &&
cd {{path_administrator_scripts}}backup-docker-to-local &&
bash ./recover-docker-from-local.sh "nextcloud_data" "$(sha256sum /etc/machine-id | head -c 64)"
