Kubernetes : why is HostIP ignored in my pod manifest
You have to add hostNetwork= true so it the pod will share host's network space.
For example you can deploy following manifest:
apiVersion: v1kind: Podmetadata: name: secondpodspec: containers: - name: container image: hashicorp/http-echo args: - "-text=banana" ports: - containerPort: 5678 hostIP: 10.156.0.46 hostPort: 5678 restartPolicy: Never hostNetwork: trueWhere 10.156.0.46 is my host's IP and once deployed:
$ kubectl get pod -o wideNAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATESsecondpod 1/1 Running 0 10m 10.156.0.46 worker <none> <none>you can successfully curl it:
$ curl 10.156.0.46:5678banana
