Openshift

Deploy using OpenShift Container Platform

The easiest way to get Openshift installed is using OpenShift Container Platform

Machines types

You can set AWS machines types or GCP machines types to your master and workers nodes using plaform parameter in your install-config.yaml file.

Example for AWS:

platform:
    aws:
      type: c5.4xlarge

Example for GCP:

  platform:
    gcp:
      type: n2-standard-4

This allow you to get more ressources in order to deploy Loki for example.

Using OCP

You can customize your OCP installation using install-config.yaml file.

Generate the configuration using:

openshift-install create install-config --dir=<installation_directory>

Metrics

NetObserv comes with a bunch of metrics, however they are not scraped by default by OpenShift Cluster Monitoring (the OpenShift cluster Prometheus that is used for infra monitoring).

You can install your own Prometheus to scrape NetObserv's metrics.

As an alternative, you can also tell OpenShift Cluster Monitoring to scrape all user metrics, not just infra (provided as "USE AT YOUR OWN RISK": depending on your running workloads and their metrics, it may put pressure on Prometheus and make it unstable).

We provide some YAML to do so:

oc apply -f https://raw.githubusercontent.com/netobserv/documents/main/examples/metrics/monitoring.yaml

It will create a Service for flowlogs-pipeline metrics, two ServiceMonitors (for flowlogs-pipeline and the console plugin), and configure Cluster Monitoring to scrape user metrics.

The generated metrics are prefixed with netobserv_ or flow_.
