I am currently learning Kubernetes and I am using Minikube on MacOS using Docker Desktop, I am facing issues with running Kibana which seems to be failing to start and to also enable it through my nginx ingress controller.
Regarding Kibana, it doesn't move to ready stage, it seems to be stuck and restarts several times. Everything lives inside the default namespace, except for fluentd that I use a persistent volume and persistent volume claim to access the shared /data/logs folder.
I have added my fluentd, kibana, es and ingress yaml configuration. And also kibana logs below.
