A Docker Compose configuration example on deploying Seafile. In this example I'll deploy it in a Traefik proxy network and with the appropriate Traefik labels.
There are 3 services that make up Seafile. A MariaDB, Memcached key-value store and Seafile itsself. If you look closely, you can see that there are two networks,
traefik-proxy which should exist and
seafile which Docker Compose will create. All 3 services are added to the
seafile network and the
seafile service is also added to the already existing
traefik-proxy network, for enabling Traefik to proxy traffic to the service.
You need to change the environment variables highlighted in the code below. Notice that
SEAFILE_SERVER_LETSENCRYPT is set to
false. That's because Traefik handles my LE certificates, not Seafile.
Change Traefik labels on the
seafile service to fit your needs. Remember, if your Traefik network is different to
traefik-proxy, change the
traefik.docker.network label aswell.

After deploying above Docker Compose file, there is just one more thing you need to fix. Personally I would call it a bug, but according to the developer, its by design. The issue is that a couple of variable needs to be fixed for Seafile to get content.
Open a shell in the
docker exec -it seafile bash
/opt/seafile/conf/ccnet.conf file with
vi. (Sorry peeps, only the
vi editor is available in the container)
[General] SERVICE_URL = http://cloud.example.org:8000 ...
SERVICE_URL variable to fit your needs. If you are using SSL, remember to change
https. And of course if you are using port
443, just delete the port section.
[General] SERVICE_URL = https://cloud.example.org
The same thing goes for the
FILE_SERVER_ROOT variable in
/opt/seafile/conf/seahub_settings.py, if you are using SSL/HTTPS.
... FILE_SERVER_ROOT = "https://cloud.example.org/seafhttp"
Restart all Docker Compose services and you are good to go.
An issue has been raised with the developer about this "design". https://github.com/haiwen/seafile-docker/issues/182 (opens new window)
