**draft, do not merge**

Closes #24

Notes

Environment Variables (.env)

-> Should be added to https://github.com/datamate-rethink-it/seafile-admin-docs

# SeaDoc
SEAHUB__ENABLE_SEADOC=true
SEAHUB__SEADOC_PRIVATE_KEY='TODO: Generated by pwgen'
SEAHUB__SEADOC_SERVER_URL=https://${SEAFILE_SERVER_HOSTNAME}/sdoc-server
SEAHUB__FILE_CONVERTER_SERVER_URL='http://sdoc-server:8888'

Required manual changes 🤷

/opt/seadoc-data/sdoc-server/conf/sdoc_server_config.json

Set private_key to the value of SEAHUB__SEADOC_PRIVATE_KEY

/opt/seadoc-data/sdoc-server/conf/seadoc_converter_settings.py

Set SEADOC_PRIVATE_KEY to the value of SEAHUB__SEADOC_PRIVATE_KEY

.... which is not documented :)

Never delete the host volume, otherwise sdoc-server can't initialize the database 🤷

ERROR 1050 (42S01) at line 1: Table 'operation_log' already exists

(found in /opt/seadoc-data/sdoc-server/logs/init.log)

EDIT: "Solution": jump into mysql shell and drop the operation_log table inside sdoc_db 🤷

Afaict SDOC_SERVER_HOSTNAME is only used when generating the NGINX configuration, which is irrelevant since the NGINX inside seafile-server directly communicates with the services inside this container (on port 7070, plus seahub <=> seadoc_convert on port 8888).
