CoreDNS workshop

CoreDNS is a fast and flexible Domain Name Server.

Some interesting capabilities are

• Serve zone data from a file; both DNSSEC (NSEC only) and DNS are supported (file)

• Retrieve zone data from primaries, i.e., act as a secondary server (AXFR only) (secondary)

• Sign zone data on-the-fly (dnssec).

• Load balancing of responses (loadbalance).

• Allow for zone transfers, i.e., act as a primary server (file).

• Automatically load zone files from disk (auto).

• Caching (cache).

• Health checking endpoint (health).

• Implements "chain of responsibility" pattern.

• Chains HTTP middleware.

• can talk to multiple backends such as etcd.

• flexible processing of DNS data

CoreDNS is repurposed beyond Caddy, SkyDNS and is a replacement for BIND in microservice environments.
