In Kubernetes clusters, the Domain Name System (DNS) plays a crucial role in enabling service discovery for pods to locate and communicate with other services within the cluster. DNS infrastructure misconfigurations, failures or performance degradation can lead to application latency, transaction timeouts, or poor end-user experience. As these issues are sporadic, making it difficult to diagnose and resolve, resulting in prolonged downtime and frustration for application and DevOps teams.

In this webinar, we will explore how you can quickly troubleshoot the following common DNS scenarios:

  1. DNS traffic deny
  2. DNS “SERVFAIL” response code errors
  3. DNS “NXDOMAIN” response code errors
  4. DNS “NOERROR” with missing records
  5. “core-dns” load-balancing issues
