aws-alb-ingress-controller - query string rule

[Amit De]

Hey,

I have a kubernetes cluster running on EKS and I am using the ALB AWS Ingress Controller and Im trying to create a query string condition pointing to a service inside the cluster.

the Ingress Annotations page in the documentation says "ServiceName/ServicePort can be used in forward action(advanced schema only)." 

I cant seem to find what is the advanced schema. 

does anyone know how to make this kind of thing work ?

this is what Im adding in the annotations :

alb.ingress.kubernetes.io/actions.ccproxy: '{"Type":"forward","ForwardConfig":{"ServiceName":"kccproxy","ServicePort":"80","Weight":100}}'

alb.ingress.kubernetes.io/conditions.ccproxy: '[{"Field":"query-string","QueryStringConfig":{"Values":[{"Key":"test","Value":"test"}]}}]'

and this the error I get in the alb ingress controller pod:

1 controller.go:217] kubebuilder/controller "msg"="Reconciler error" "error"="failed to reconcile l

isteners due to failed to reconcile rules due to failed modifying rule 12 on arn:aws:elasticloadbalancing:us-west-2:xxxxxxxxxxx:listener/app/xxxxxxxxxxxx/xxxxxxx due to ValidationError: '' is not a valid target

group ARN\n\tstatus code: 400, request id: xxxxxxxxxxxxxxx"  "controller"="alb-ingress-controller" "reques

Thanks :)

Never came across this error but how's your target-type defined? By default it is set to "instance"

Take a look at this and try changing it to "ip" (which is basically routing the traffic to pod ip) and see if that helps
