Add this
server.servlet.session.timeout=86400
to /etc/rundeck/rundeck-config.properties to increase duration of user sessions to 1 day, so users will stay logged in longer.
If running in docker you need to set the RUNDECK_SERVER_SESSION_TIMEOUT variable. Example from docker compose file:
---
version: '3'
services:
rundeck:
...
environment:
- TZ=Europe/Berlin
- RUNDECK_SERVER_SESSION_TIMEOUT=86400
...
...
This will set the server.servlet.session.timeout in /home/rundeck/server/config/rundeck-config.properties
