Dynamic Network configuration (via webconsole)

UDM polls the webconsole every 5 seconds to fetch the latest PLMN configuration.

Setting Up Polling

Include the webuiUri of the webconsole in the configuration file

configuration:
  ...
  webuiUri: https://webui:5001 # or http://webui:5001
  ...

The scheme (http:// or https://) must be explicitly specified. If no parameter is specified, UDM will use http://webui:5001 by default.

HTTPS Support

If the webconsole is served over HTTPS and uses a custom or self-signed certificate, you must install the root CA certificate into the trust store of the UDM environment.

Check the official guide for installing root CA certificates on Ubuntu: Install a Root CA Certificate in the Trust Store
