What Happens When Your Kubernetes Cluster Can't Find Its initial DNS Server?

By Jorg Mertin posted 16 days ago
Be the first person to recommend this.
In a healthy Kubernetes environment, the CoreDNS service is the silent resolver. It ensures that when your application tries to reach orders-db , it is routed to the correct internal IP. But what happens during those critical first seconds of a cluster start if your primary, configured DNS server is unreachable? Many engineers are surprised to find that instead of simply failing, the cluster often falls back to "Public Defaults" - specifically Google ( 8.8.8.8 ) and Cloudflare ( 1.1.1.1 ). While this keeps the cluster alive, it can create a “non critical” situation for security and internal service discovery. On critical in the way that the cluster ...

How Network I/O Delays Suffocate Your Containers

By Jorg Mertin posted 28 days ago
Be the first person to recommend this.
How Network I/O Delays Suffocate Your Containers in the world of microservices and Kubernetes, containers promise agility, scalability, and efficiency. We package our applications, deploy them, and expect lightning-fast performance. But often, there's a silent killer lurking beneath the surface, especially when our applications start to scale: network-induced I/O delays. It's easy to assume I/O is all about disk reads and writes. However, in a distributed container environment, a significant portion of "I/O" is actually network-bound. Every time your application needs to talk to another microservice, a database, or a persistent storage volume like ...
