Syntax and Options: Clear examples of plugin syntax, configuration options, and common parameters.
Use Case: You need to set up CoreDNS to forward internal domain queries to a specific internal DNS server while forwarding all other queries to public DNS resolvers, and you need to know the exact forward plugin configuration.

FAQPage Schema

How do I configure CoreDNS to forward internal queries to a private DNS server?▼

To configure CoreDNS forwarding, use the forward plugin to specify upstream DNS resolvers. You can define separate policies for internal domain queries versus public DNS traffic within your server setup.

What is the correct CoreDNS plugin syntax for setting up authoritative zones?▼

The file plugin enables authoritative zone configuration in CoreDNS by loading DNS records from a specified file. This allows you to serve custom domain resolution strategies directly from your server.

Can I use CoreDNS to rewrite DNS queries before resolving them?▼

Yes, the rewrite plugin in CoreDNS allows you to modify incoming DNS queries before they are processed. This is useful for redirecting traffic or altering domain names to match internal resolution policies.

How does the CoreDNS cache plugin improve DNS server performance?▼

The cache plugin stores DNS responses temporarily, reducing the load on upstream resolvers and improving query resolution speed. It enables configurable caching TTLs for your CoreDNS server setup.

Does CoreDNS support restricting DNS access based on client IP addresses?▼

Yes, the acl plugin allows you to define secure network access policies in CoreDNS. You can block or allow specific IP ranges to control which clients can query your DNS server.

How do I integrate CoreDNS with a Kubernetes cluster for service discovery?▼

The kubernetes plugin integrates CoreDNS with Kubernetes to provide in-cluster service discovery. It configures the DNS server to resolve pod and service names directly from the cluster API.
