CoreDNS vs SkyDNS: What are the differences?

CoreDNS: DNS and Service Discovery. CoreDNS is a DNS server. It is written in Go. It can be used in a multitude of environments because of its flexibility; SkyDNS: Distributed service for announcement and discovery of services. SkyDNS is a distributed service for announcement and discovery of services. It leverages Raft for high-availability and consensus, and utilizes DNS queries to discover available services. This is done by leveraging SRV records in DNS, with special meaning given to subdomains, priorities and weights (more info here: http://blog.gopheracademy.com/skydns).

CoreDNS and SkyDNS are primarily classified as "DNS Management" and "Open Source Service Discovery" tools respectively.

Some of the features offered by CoreDNS are:

  • Plugins
  • Service Discovery
  • Fast and Flexible

On the other hand, SkyDNS provides the following key features:

  • You announce your service by submitting JSON over HTTP to SkyDNS with information about your service. This information will then be available for queries either via DNS or HTTP.
  • SkyDNS requires that services submit an HTTP request to update their TTL within the TTL they last supplied. If the service fails to do so within this timeframe SkyDNS will expire the service automatically. This will allow for nodes to fail and DNS to reflect this quickly.
  • You can find services by querying SkyDNS via any DNS client or utility. It uses a known domain syntax with wildcards to find matching services.

CoreDNS and SkyDNS are both open source tools. It seems that CoreDNS with 4.32K GitHub stars and 695 forks on GitHub has more adoption than SkyDNS with 1.97K GitHub stars and 301 GitHub forks.
