richiesgr commented 5 years ago

Hi I'm trying to apply your config to deploy nifi on EKS (AWS) I've succeed so far to deploy nifi but a problem occurs when deploying frontend the pod crash because NginX can't find host nifi defined in frontend.conf So I get this error 2019/05/07 09:46:30 [emerg] 1#1: host not found in upstream "nifi" in /etc/nginx/conf.d/frontend.conf:5 nginx: [emerg] host not found in upstream "nifi" in /etc/nginx/conf.d/frontend.conf:5

could you help me ? Thanks

You have to change in /nifi-frontend/frontend.conf:

@richiesgr Hi, is it the cluster mode?

Which part of the guide are you following?

richiesgr commented 5 years ago

Hi Yes I've followed the cluster mode tutorial and I try to deploy on EKS 1.11 on AWS. but I think it could be related to this problem CoreDNS support for ExternalName services is broken in EKS 1.11 as you use ExternalName to resolve nifi host name for NginX What do you think ? Thanks

Hi Update may be worth to add this to your documentation. The core-dns 1.1.3 used by default on EKS 1.11 is broken for externalName service. it's not enough to update EKS to 1.12 you must update the core-dns to version 1.2.2 After upgrade all is working as expected Thanks
