Running two kubernetes pods on differents nodes

Seems like it can be done with Interpod Affinity you can see :

apiVersion: apps/v1kind: Deploymentmetadata:  name: web-serverspec:  selector:    matchLabels:      app: testApp-front  replicas: 3  template:    metadata:      labels:        app: testApp-front    spec:      affinity:        podAntiAffinity:          requiredDuringSchedulingIgnoredDuringExecution:          - labelSelector:              matchExpressions:              - key: app                operator: In                values:                - testApp-front            topologyKey: "kubernetes.io/hostname"        podAffinity:          requiredDuringSchedulingIgnoredDuringExecution:          - labelSelector:              matchExpressions:              - key: app                operator: In                values:                - store            topologyKey: "kubernetes.io/hostname"      containers:      - name: web-testApp-front        image: nginx:1.12-alpine

you can see the full example here

I think you need the concept of pod anti-affinity. This is within one cluster to take care that pods do not reside on one worker-node. https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity

very simple you can use deamon set to run every pod in diffrent node or as the others said you can use pod anti-affinity
