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.

Docker Compose

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.

Minor fix

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 seafile container.

docker exec -it seafile bash

Open /opt/seafile/conf/ccnet.conf file with vi. (Sorry peeps, only the vi editor is available in the container)

vi /opt/seafile/conf/ccnet.conf

[General]
SERVICE_URL = http://cloud.example.org:8000
...

Change the SERVICE_URL variable to fit your needs. If you are using SSL, remember to change http to https. And of course if you are using port 80 or 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.

docker-compose restart

An issue has been raised with the developer about this "design". https://github.com/haiwen/seafile-docker/issues/182 (opens new window)
