Hi,

I can run splunk as a docker image - no problem. But running in Openshift it crashes running sudo (assume in entrypoint.sh script).

image splunk/splunk:7.3.0

ERROR: Couldn't read "/opt/splunk/etc/splunk-launch.conf" -- maybe $SPLUNK_HOME or $SPLUNK_ETC is set wrong?

Generally openshift oc disallows sudo.

Thanks

OKAY. Found a dirty work around which is a security threat.
Need to add users as sudo and strip out openshift restrictions on allowable capabilities.
including SETUID GETUID. Unfortunately the entrypoint.sh should just run as 1 user splunk and not sudo between splunk and ansible.
uneccessary.
