An HTTP router and reverse proxy for service composition from Zalando. #golang


Skipper is an HTTP router and reverse proxy for service composition. It’s designed to handle >100k HTTP route definitions with detailed lookup conditions, and flexible augmentation of the request flow with filters. It can be used out of the box or extended with custom lookup, filter logic and configuration sources.

Main features:

An overview of deployments and data-clients shows some use cases to run skipper.

Skipper

  • identifies routes based on the requests’ properties, such as path, method, host and headers
  • allows modification of the requests and responses with filters that are independently configured for each route
  • simultaneously streams incoming requests and backend responses
  • optionally acts as a final endpoint (shunt), e.g. as a static file server or a mock backend for diagnostics
  • updates routing rules without downtime, while supporting multiple types of data sources — including etcdKubernetes IngressInnkeeperstatic filesroute string and custom configuration sources
  • can serve as a Kubernetes Ingress controller without reloads. You can use it in combination with a controller that will route public traffic to your skipper fleet; see AWS example
  • shipped with eskip: a descriptive configuration language designed for routing rules

Skipper provides a default executable command with a few built-in filters. However, its primary use case is to be extended with custom filters, predicates or data sources. Go here for additional documentation.
