Kubernetes¶
Skipper’s Kubernetes dataclient can be used, if you want to run Skipper as kubernetes-ingress-controller. It will get its route information from provisioned Ingress Objects. Detailed information you find in our godoc for dataclient kubernetes.

Why to choose Skipper?¶
Kubernetes is a fast changing environment and traditional http routers are not made for frequently changing routing tables. Skipper is a http proxy made to apply updates very often. Skipper is used in production with more than 200.000 routing table entries. Skipper has Filters to change http data and Predicates to change the matching rules, both can combined and chained. You can set these in ingress.yaml files to build resiliency patterns like ratelimit or circuitbreaker. You can also use them to build more highlevel deployment patterns, for example feature toggles, shadow traffic or blue-green deployments.
Skipper’s main features:
- Filters - create, update, delete all kind of HTTP data
- collection of base http manipulations: for example manipulating Path, Querystring, ResponseHeader, RequestHeader and redirect handling
- cookie handling
- circuitbreakers: consecutiveBreaker or rateBreaker
- ratelimit: based on client or backend data
- Shadow traffic: tee()
- Predicates - advanced matching capability
- URL Path match:
Path("/foo")
- Host header match:
Host("^www.example.org$")
- Querystring:
QueryParam("featureX")
- Cookie based:
Cookie("alpha", /^enabled$/)
- source whitelist:
Source("1.2.3.4/24")
- time based interval
- traffic by percentage supports also sticky sessions
- Kubernetes integration
- All Filters and Predicates can be used with 2 annotations
- Predicates:
zalando.org/skipper-predicate
- Filters:
zalando.org/skipper-filter
- Predicates:
- Custom routes can be defined with the annotation
zalando.org/skipper-routes
- metrics
- access logs
- Blue-Green deployments, with another Ingress annotation
