Describe the bug I having issue running dkron in Kubernetes using Minicuke on mac.

To Reproduce Steps to reproduce the behavior:

Below deployment file.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: kcron-deployment
spec:
  selector:
    matchLabels:
      app: dkron
  replicas: 1
  template:
    metadata:
      labels:
        app: dkron
    spec:
      containers:
        - name: kcronmaster
          image: dkron/dkron
          ports:
            - containerPort: 8080
            - containerPort: 8946
            - containerPort: 6868
          command: ["dkron"]
          # command: ["dkron agent --server --log-level=debug --bootstrap-expect=1"]
          # command: ["./opt/local/dkron/dkron --server --log-level=debug --bootstrap-expect=1"]
          # args: ["--server --log-level=debug --bootstrap-expect=1"]
          env:
          - name: GODEBUG
            value: netdns=go
          resources:
            requests:
              memory: "512Mi"
              cpu: "500m"
            limits:
              memory: "512Mi"
              cpu: "500m"

Expected behavior Should have dkron service running

Hi @victorcoder

I also have this issue using minikube version v1.22.0 on my macOS. Why do I use minikube instead of docker-compose on my local machine? Because of I am trying to reproduce issue #998. I want to create about 30 - 50 nodes and 200 jobs. Can someone help?

My kubectl version is like this.
