|
## database access
|
|
To access the database execute
|
|
```bash
|
|
docker exec -it nextcloud_database_1 /bin/mysql -u nextcloud -p
|
|
```
|
|
|
|
## update
|
|
|
|
To update the nextcloud container execute the following commands on the server:
|
|
|
|
```bash
|
|
export COMPOSE_HTTP_TIMEOUT=600
|
|
export DOCKER_CLIENT_TIMEOUT=600
|
|
cd /home/administrator/docker-compose/nextcloud &&
|
|
docker-compose pull &&
|
|
docker-compose up -d
|
|
```
|
|
|
|
Afterwards update the ***nextcloud_version*** variable to the next version and run the server manager.
|
|
|
|
It is only possible to update from one to the next major version at a time
|
|
|
|
You can check the status of the update by typing in:
|
|
|
|
```bash
|
|
docker logs nextcloud_application_1
|
|
```
|
|
|
|
If nextcloud stays in the maintenance mode after the update try the following:
|
|
|
|
```bash
|
|
docker exec -it -u www-data nextcloud_application_1 /var/www/html/occ maintenance:mode --on
|
|
docker exec -it -u www-data nextcloud_application_1 /var/www/html/occ upgrade
|
|
docker exec -it -u www-data nextcloud_application_1 /var/www/html/occ maintenance:mode --off
|
|
```
|
|
|
|
If the update process fails execute
|
|
|
|
```bash
|
|
docker exec -it -u www-data nextcloud_application_1 /var/www/html/occ maintenance:repair
|
|
```
|
|
|
|
and disable the mal functioning apps.
|
|
|
|

|
cd /usr/local/bin/docker-volume-backup &&
|
|
bash ./docker-volume-recover.sh "nextcloud_data" "$(sha256sum /etc/machine-id | head -c 64)" &&
