Monitoring Kubernetes Cluster with Prometheus, using NodePort Method
I’m implementing a solution in Kubernetes for several clients, and I want to monitoring my cluster with Prometheus. However, because this can scale quickly, and I want to reduce costs, I will use Federation for Prometheus, to scrape different clusters of Kubernetes, but I need to expose my Prometheus deployment.
I already have that working with a service type LoadBalancer exposing my Prometheus deployment, but this approach add this extra expense to my infra structure (Digital Ocean LB).
Is it possible to make this using a service type NodePort, exposing a port to my Cluster IP, something like this:
Where I can use this URL to my master Prometheus scrappe all “slaves” Prometheus instances?
I already tried, but I can’t reach my cluster port. Something is blocking. I also delete my firewall, to ensure that nothing is interferes in this implementation but nothing.
Can anybody help me please?
