> FlinkBlueGreenDeployment Kubernetes Networking Update / Ingress not Stable
> --------------------------------------------------------------------------
>
> Key: FLINK-38577
> URL: https://issues.apache.org/jira/browse/FLINK-38577
> Project: Flink
> Issue Type: Bug
> Components: Kubernetes Operator
> Reporter: Daniel Rossos
> Priority: Major
> Labels: pull-request-available
>
> Both the blue and green FlinkDeployments attempt to create their own service
> for their Flink pipeline, but only the initial Flink Blue deployment will
> create an ingress and Green will have issues creating one at the same route.
> This results in problems as when Blue goes down in favour of Green the
> ingress will be lost.
> Example error event from Green deployment on startup. Will still work
> normally, but ingress creation fails.
> {code:java}
> JobManagerDeployment Failure executing: POST at:
> https://<IP>/apis/networking.k8s.io/v1/namespaces/<NS>/ingresses. Message:
> admission webhook "validate.nginx.ingress.kubernetes.io" denied the request:
> host "<ADDRESS>" and path "/" is already defined in ingress
> <BlueDep-Ingress>/<name>-blue. Received status: Status(apiVersion=v1,
> code=400, details=null, kind=Status, message=admission webhook
> "validate.nginx.ingress.kubernetes.io" denied the request: host "<ADDRESS>"
> and path "/" is already defined in ingress <BlueDep-Ingress>/<name>-blue,
> metadata=ListMeta(_continue=null, remainingItemCount=null,
> resourceVersion=null, selfLink=null, additionalProperties={}){code}
> We should have a more nuanced Service + Ingress Kubernetes networking
> solution for BlueGreen deployments. Naive / first thoughts would be something
> like 1 svc and 1 ingress that will dynamically bind to whatever
> FlinkDeployment is active, but have opened this discussion thread for further
> ideation [https://lists.apache.org/thread/64d2xnh6ddqqd91ydl91t6rzf9xrkb7n]
