Universal forwarder sidecar deployment- Where to locate user and password, and confusion with url?

[DukeScottWu]

Hey community

We are using Universal forwarder as a sidecar in K8S following github introduction.

But the document is not clear enough and cannot guide us to integrate with server.

env:
           - name: SPLUNK_START_ARGS
             value: --accept-license
           - name: SPLUNK_USER
             value: root
           - name: SPLUNK_GROUP
             value: root
           - name: SPLUNK_PASSWORD
             value: helloworld
           - name: SPLUNK_CMD
             value: add monitor /var/log/
           - name: SPLUNK_STANDALONE_URL
             value: splunk.company.internal

Some questions for about configurations:

1. splunk user and password:  where can we get this user and password? shall we allocate an account from splunk enterprise server?

2. SPLUNK_STANDALONE_URL:   is this splunk enterprise server URL?  is it possible to get this URL from splunk server?
