We have two k8s clusters:
Cluster details:
Cluster 1:
Pod Network: 172.16.1.0/24
Node Network: 172.16.2.0/24
Cluster 2:
Pod Network: 172.16.3.0/24
Node Network: 172.16.4.0/24
All these networks are connectivity to one another.
Suppose we have 3 pods in each clusters
Cluster1-Pod1: IP: 172.16.1.1
Cluster1-Pod2: IP: 172.16.1.2
Cluster1-Pod3: IP: 172.16.1.3
Cluster2-Pod1: IP: 172.16.3.1
Cluster2-Pod2: IP: 172.16.3.2
Cluster2-Pod3: IP: 172.16.3.3
How can one access the apps of pods in cluster2
from cluster1
without creating a k8s
service using Pod IP or hostname
. Any solution available to publish/advertise pods IP/hostname
from one cluster to another? If creating a service is mandatory, any options to achieve it without Type: LoadBlanacer or Ingress?
Appreciate any inputs.
Are you sure you are not confusing nodes with clusters? Because if these pods exist on different nodes, within the same cluster, then you can simply access the pod with its IP.
Otherwise, it is not possible to connect to your pod outside the cluster without making your pod public by a service(NodePort, LoadBalancer) or Ingress.
