Rancher is an open-source platform designed to manage Kubernetes clusters. It provides a user-friendly interface for deploying, managing, and scaling containerized applications across multiple clusters. Rancher simplifies Kubernetes cluster management by offering features like multi-cluster management, application catalogs, and integrated monitoring and alerting.
One common issue users encounter in Rancher is when the ingress is not working. This symptom is observed when applications deployed in the Kubernetes cluster are not accessible via the expected URLs. Users might notice that requests to the application result in 404 errors or timeouts, indicating that the ingress is not routing traffic correctly.
The root cause of ingress not working often lies in misconfigured ingress rules or DNS issues. Ingress rules define how external HTTP/S traffic should be routed to services within the cluster. If these rules are incorrect or if the DNS is not properly configured to point to the ingress controller, the traffic will not reach the intended services.
To resolve the ingress not working issue, follow these steps:
kubectl get ingress --all-namespaces
kubectl get pods -n ingress-nginx
kubectl logs <ingress-controller-pod-name> -n ingress-nginx
For more detailed information on configuring ingress in Kubernetes, refer to the official Kubernetes Ingress Documentation. Additionally, the Rancher Documentation provides comprehensive guides on managing ingress and other networking components in Rancher.
