dr-network-check

Network connectivity checker for Data Foundation (DF) disaster recovery configurations.

Overview

dr-network-check verifies network connectivity requirements across multi-cluster DF DR setups. It checks:

Ceph daemon ports: Mon and OSD port reachability between ODF clusters (when CephCluster hostNetwork is enabled)
S3 routes: S3 endpoint reachability from hub and client clusters
OCS provider server: LoadBalancer, NodePort, and ClusterIP service connectivity between base clusters, including Submariner/GlobalNet validation
Proxy/noProxy: Ensures all endpoints are properly configured in the cluster proxy settings

Usage

Generate configuration

dr-network-check init

This creates a config.yaml with placeholders. Edit it to set kubeconfig paths for your clusters.

Run checks

dr-network-check check-network

Use --config to specify a custom config file:

dr-network-check check-network --config /path/to/config.yaml

Configuration

clusters:
  hub:
    kubeconfig: "/path/to/hub/kubeconfig"
  hub-passive:
    kubeconfig: ""
  c1:
    kubeconfig: "/path/to/c1/kubeconfig"
  c2:
    kubeconfig: "/path/to/c2/kubeconfig"
  c1-client-1:
    kubeconfig: ""
  c2-client-1:
    kubeconfig: ""

checks:
  skip-ceph-daemon-check: false
  skip-s3-check: false
  skip-provider-check: false

# test-pod-image: "registry.access.redhat.com/ubi9/ubi:latest"
