EKS installation with ALB, hostname and multi AZ configured, target group healthcheck fails.

[nabello]

Hello everyone, When deploying a Fusion 5 EKS setup with an ALB, hostname, multi AZ and no monitoring configured on top of default options as follows: ./setup_f5_eks.sh -c sandbox-f5 -p eks-sandbox -z us-west-2 -i m5.2xlarge --deploy-alb -h sandbox-f5.example.com --prometheus none --num-solr 1 --solr-disk-gb 50 --create multi_az the resulting target group you are left with fails healthchecks which blocks access to the cluster.

The reason behind this seems to be because the target group is deployed with alb.ingress.kubernetes.io/healthcheck-path not set which then uses it's default value "/".

By adding alb.ingress.kubernetes.io/healthcheck-path: "/auth/" after line 450 of setup_f5_eks.sh this seems to fix the issue so that the only thing required after applying the command above (with your personal values for options) is to take care of DNS mapping.

Hope this help others, maybe a PR needs to be made for this issue to fix it for everyone using setup_f5_eks.sh to properly deploy Fusion 5 to EKS with an ALB (--deploy-alb) and a hostname (e.g -h sandbox-f5.example.com) ?
