Notes for WebDAV

You may need to add the following lines to your docker file if you plan on enabling WebDAV.

    ports:
      - "8080:8080"

After that you do this open this port on your firewall and redirect it to the Docker Host's IP with seafile running on it.

docker-compose up -d

After you have the .env and docker-compose files set up in this directory. Do a docker-compose up -d to start the containers. After they start modify seahub_settings.py, ccnet.conf, and maybe gunicorn.conf.py (if you have connnection refused issues) as shown below.

seahub_settings.py

sudo nano ~/docker/seafile/seafile-data/seafile/conf/seahub_settings.py

Change FILE_SERVER_ROOT to be https instead of http. Example Below:

FILE_SERVER_ROOT = "https://subdomain.example.com/seafhttp"

ccnet.conf

sudo nano ~/docker/seafile/seafile-data/seafile/conf/ccnet.conf

Change SERVICE_URL from http to https and remove the :8000 at the end. Example Below:

SERVICE_URL https://subdomain.example.com

gunicorn.conf.py

sudo nano ~/docker/seafile/seafile-data/seafile/conf/gunicorn.conf.py

According to @DemoniWaari #3 you may need to change the default bind = "127.0.0.1:8000" to bind = "0.0.0.0:8000" if you get a connection refused error.

Optional: seafile.conf - changing upload file size limit

You can change your upload size limits by editing max_upload_size=1000 seafile.conf... The number is in GBs

sudo nano ~/docker/seafile/seafile-data/seafile/conf/seafile.conf

Optional: Setting Up WebDav

Caddyfile

webdav.example.com {
	reverse_proxy seafile:8080
}

Here I assigned a new subdomain webdav and point it to port 8080 which is the defualt on seafdav.conf

seafdav.conf

nano ~/docker/seafile/seafile-data/seafile/conf/seafdav.conf

Set enabled=true Set share_name = / Example Below

[WEBDAV]
enabled = true
port = 8080
fastcgi = false
share_name = /

Remember to do a docker-compose restart and a caddy exec restart after modifying seafile conf files!

Maintainance - Freeing Space

When you delete files in seafile and empty trash in the web UI, it doesn't free up space on your server. After emptying trash in the webUI you should run the garbage collector w/ the command below to free up space.

docker exec seafile /scripts/gc.sh
