WebGUI Error 503 after pod deployment

Rancher 2.x
1

I started this pod via kubectl from the official kubernetes docs (except the name, gitlab image, replicas: 1):
–> https://kubernetes.io/docs/concepts/services-networking/connect-applications-service/#exposing-pods-to-the-cluster

apiVersion: apps/v1
kind: Deployment
metadata:
  name: pod-gitlab-1
spec:
  selector:
    matchLabels:
      run: pod-gitlab-1
  replicas: 1
  template:
    metadata:
      labels:
        run: pod-gitlab-1
    spec:
      containers:
      - name: pod-gitlab-1
        image: gitlab/gitlab-ee:latest
        ports:
        - containerPort: 80

I started the pod via kubeclt web gui:
kubectl create -f pod-gitlab-1.yml

Then the pod was running after 1-2 minutes but then I noticed it was directly terminated after initialisation and the cluster automatically has started a new one.
After that point I anymore wasn’t able to access the web GUI entirely because of 503 error response.
SSH login to cluster works.

New cluster configuration via:
./rke_linux-amd64 up --config rancher-cluster.yml
doesn’t progress after:
INFO[0131] [healthcheck] Start Healthcheck on service [kube-apiserver] on host [104.248.22.7]

I think it loops in some way and kills the cluster?

Other theory:
I have a nginx loadbalancer in front of the cluster that redirects to my 3 master nodes (loadbalancer has ssl certs, rancher not).
Is it possible that the new gitlab port spec blocks the access for the loadbalancer that makes a port 80 proxy to the main nodes?

The question:
How can I kill this pod without access to the WebGUI?

Thanks a lot :slight_smile:
