Hi,
I switched from “native” to docker for my Seafile installation.
I used the docker-compose from the manual:
version: ‘2.0’
services:
db:
image: mariadb:10.5
container_name: seafile-mysql
environment:
- MYSQL_ROOT_PASSWORD=XXXX # Requested, set the root’s password of MySQL service.
- MYSQL_LOG_CONSOLE=true
- TIME_ZONE=Europe/Berlin # Optional, default is UTC. Should be uncomment and set to your local time zone.
volumes:
- /opt/seafile-mysql/db:/var/lib/mysql # Requested, specifies the path to MySQL data persistent store.
networks:
- seafile-netmemcached:
image: memcached:1.5.6
container_name: seafile-memcached
entrypoint: memcached -m 256
networks:
- seafile-netseafile:
image: seafileltd/seafile-mc:latest
container_name: seafile
ports:
- “8443:80”
#- “8482:8082” # If https is enabled, cancel the comment.
- “8480:8080”
volumes:
- /opt/seafile-data:/shared # Requested, specifies the path to Seafile data persistent store.
environment:
- DB_HOST=db
- DB_ROOT_PASSWD=XXXX # Requested, the value shuold be root’s password of MySQL service.
- TIME_ZONE=Europe/Berlin # Optional, default is UTC. Should be uncomment and set to your local time zone.
- SEAFILE_ADMIN_EMAIL=${SEAFILE_USER} # Specifies Seafile admin user, default is ‘me@example.com’.
- SEAFILE_ADMIN_PASSWORD=${SEAFILE_PW} # Specifies Seafile admin password, default is ‘asecret’.
- SEAFILE_SERVER_LETSENCRYPT=false # Whether to use https or not.
- SEAFILE_SERVER_HOSTNAME=xx.xx.xx # Specifies your host name if https is enabled.

All 3 containers are up and running and I can bash into them. I see the database running in the mysql container and I see, that in the Seafile container, Seafile isn’t running. It seems, that since tonight at 01:30 am it stopped working.

I restarted and recreated the containers from the docker-compose, but without success.
I can’t find the issue.
The last thing I changed at 2022-01-04 , was installing pihole as a container with DNS/DHCP, following the instructions on docker-pi-hole GitHub Page, (sorry can’t link that) on an Ubuntu System.
Maybe somehow this made some problems, but I can’t find it 
Anyone some ideas to point me to solve this ?
Regards
