Vulcand

Vulcand is a programmatic extendable proxy for microservices and API management. It is inspired by Hystrix and powers Mailgun microservices infrastructure.

What it's not

It's not general-purpose reverse proxy - it is focused on microservices and API use-cases.

Features

  • Uses Etcd as a configuration backend.
  • API and command line tool.
  • Pluggable middlewares.
  • Support for canary deploys, realtime metrics and resiliency.

Package threshold contains predicates that can define various request thresholds Examples: * RequestMethod() == "GET" triggers action when request method equals "GET" * IsNetworkError() - triggers action on network errors * RequestMethod() == "GET" && Attempts <= 2 && (IsNetworkError() || ResponseCode() == 408) This predicate triggers for GET requests with maximum 2 attempts on network errors or when upstream returns special http response code 408
