8085304cb9 Separate the ExternalName backend from other backends in the process of synchronizing the backend, because the synchronization of the ExternalName backend requires dns resolution, so we should ensure that it does not affect the synchronization of the Non-ExternalName backend. After separation, in the init worker stage, we should immediately synchronize the Non-ExternalName backend, otherwise there will be some requests that fail with 503 because the balancer cannot be obtained in the rewrite stage. 2020-12-22 17:24:41 +08:00

018a1e4d94 respond with 503 when there are no endpoints 
* related to:
  * https://github.com/kubernetes/ingress-nginx/issues/3070
  * https://github.com/kubernetes/ingress-nginx/issues/3335
* add a 503 test
  * test a service that starts out empty
    (a.k.a. ingress-nginx controller (re-)start)
  * test scaling up (should route traffic accordingly)
  * test scaling down to empty service
  * use custom deployments for scaling test.
* provide a fix by updating the lua table (cache) of the configured backends
  to unset the backend if there are no endpoints available.

60b983503b Consistent hashing to a subset of nodes. It works like consistent hash, 
but instead of mapping to a single node, we map to a subset of nodes.

Merge pull request #3341 from Shopify/canary_upstream 
Add canary annotation and alternative backends for traffic shaping
 2018-11-06 12:22:16 -08:00
Conor Landry
412cd70d3a implement canary annotation and alternative backends 
Adds the ability to create alternative backends. Alternative backends enable
traffic shaping by sharing a single location but routing to different
backends depending on the TrafficShapingPolicy defined by AlternativeBackends.

When the list of upstreams and servers are retrieved, we then call
mergeAlternativeBackends which iterates through the paths of every ingress
and checks if the backend supporting the path is a AlternativeBackend. If
so, we then iterate through the map of servers and find the real backend
that the AlternativeBackend should fall under. Once found, the
AlternativeBackend is embedded in the list of VirtualBackends for the real
backend.

If no matching real backend for a AlternativeBackend is found, then the
AlternativeBackend is deleted as it cannot be backed by any server.
