[jira] [Commented] (YUNIKORN-380) Deploying YUNIKORN 0.9 RC2 on
Minikube 1.3.1 results in port conflict
[ https://issues.apache.org/jira/browse/YUNIKORN-380?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17183495#comment-17183495 ]
Weiwei Yang commented on YUNIKORN-380:
--------------------------------------
I guess this only happens on single-node deployment, where 8443 is already taken by some other services. The webhook HTTP port of the admission controller currently is hardcoded to 8443.
The easiest way to fix is to replace 8443 with some other port like 9089. We are using some other ports e.g 9889, 9080 for web services, it makes sense to use a port starting from 9xxx for the admission controller as well. Since this is all internal, it should have minimal impact to the end-users.
