Kubernetes can`t access to POD that created by JOB

I tried create simple JOB in kubernetes by this YAML

apiVersion: batch/v1
kind: Job
metadata:
  name: {{ include "helper.fullname" . }}-notification-about-relese-{{ .Release.Revision }}
  labels:
    app.kubernetes.io/version: {{ .Chart.AppVersion | quote }}
  annotations:
    "helm.sh/hook": post-install,post-upgrade
    "helm.sh/hook-delete-policy": before-hook-creation
    "helm.sh/hook-weight": "5"
spec:
  backoffLimit: 1
  ttlSecondsAfterFinished: 600 
  template:
    metadata:
      labels:
        {{- if .Values.includeTimestampToPods }}
        timestamp: {{ now.UnixNano | quote }}
        {{- end }}
    spec:
      containers:
      - name: make-request
        image: "bash:5.2.15-alpine3.18"
        command: ["echo"]
        args: ["test"]
      restartPolicy: OnFailure

And looks like this job complete enter image description here

But if I try to look POD logs or try get access to POD exec I have this error enter image description here

What it means? How I can fix it? For me this looks like Kubernetes dashboard don`t have connection to POD

Solution

  • In my case problem was not related to YAML file or network. It was because in our infrastructure we have new node that not fully ready to work, because my YAML not contains spec.template.spec.affinity.nodeAffinity Kubernetes run JOB POD int this (not fully ready) POD.

    Force changed of node for running helped me to fix this issue
