Distributed service for announcement and discovery of services

What is SkyDNS?

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).

SkyDNS is a tool in the Open Source Service Discovery category of a tech stack.

SkyDNS is an open source tool with 1.95K Github Stars and 305 Github Forks. Here’s a link to SkyDNS's open source repository on Github

SkyDNS's 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.
