Seafile installation notes and guidelines

Ingress

Our install requires a FQDN or domain name entered when installing the chart. This doesn't mean you need Traefik however we support only installs using FQDN with valid certificates + Traefik installed

CSRF Error

Starting with Seafile 11, the defaults fail CSRF verification, and you may see the error message when logging in.

To fix this, the following must be added to your seahub_settings.conf file. It is found inside /shared/conf. We recommedend enabling the Code-server addon or mounting the container

Add an entry for: CSRF_TRUSTED_ORIGINS = ["https://seafile.YOURDOMAINHERE.com"]

Storage

Seafile uses Block storage so files/folders uploaded to Seafile aren't visible by default when mounting the persisted storage. For more information see the this post on the Seafile Forums. As well, Seafile uses init scripts which need to be run as root so if hostpath is used (such as using HDDs) then make sure your storage is owned by root.

Memcached Log Spam and fixes

Unfortunately there's no easy solution at the moment to add memcached automatically without user intervention (redis support is also coming soon to Seafile) so if users wish to use memcached (isn't required) then the following steps must be followed

Add dependency train to TrueCharts catalog and add/install memcached chart
Edit CACHES -> default inside seahub_settings.py to add memcached.ix-memcached.svc.cluster.local instead of memcached and you can delete the locmem.

Simply delete the CACHES section, while not optimal for large installs is truly used with 50+ users according to Seafile docs.

Either of these steps will prevents the logs filling up with:

pylibmc.ServerDown: error 47 from memcached_set_multi: SERVER HAS FAILED AND IS DISABLED UNTIL TIMED RETRY

WebDAV

By default WebDAV is disabled by default, as per upstream docs. Here's some simple instructions to modify your seafdav.conf to enable WebDAV if you wish to use it with Traefik.

Enter Seafile Pod Shell

Use the CLI to enter the Seafile WebDAV (seafdav.conf) config file

Use vi commands to edit the Enabled to true and change the share name as desired (default is /seafdav).

Use i to insert text and and :wq, and ESC key to exit insert mode

Restart Seafile and your WebDAV share will be accessible using your domain.com/seafdav

FUSE Extension

The FUSE extension isn't supported by default due to privileges required by the extension and non-standard mounts, so no support tickets will be accepted for using/enabling it.
