## Common questions

### Does Docker Desktop cause DNS resolution to differ between Kubernetes and the host?

A Docker Community thread reports different DNS behavior between Kubernetes and the host system. It discusses investigating a CoreDNS root cause related to Docker Desktop.

### Do containers outside Kubernetes use CoreDNS?

No, containers without Kubernetes do not use CoreDNS. DNS differences can come from DNS server behavior or header-size handling.

### Can a homelab use CoreDNS to publish DNS records for Ingresses?

A home Kubernetes user describes using CoreDNS as a home DNS resolver with the k8s_gateway plugin. It can automatically provision DNS records for Ingresses in a homelab setup.

### Why might Kubernetes pods intermittently fail to reach local-network services by name?

A user reports pods failing to communicate with local-network applications whose DNS address is set only on a local DNS server. The thread treats the issue as a CoreDNS resolution problem in Kubernetes.
