Service unavailable

[iluwatar]

Hi,

I followed the deployment steps at https://www.gateway-api-controller.eks.aws.dev/deploy/

Next, I tried to set up the single cluster/VPC service-to-service communications as indicated here: https://www.gateway-api-controller.eks.aws.dev/getstarted/

My problem appears in step "check service connectivity". When I exec into the pods and try to call the service using the curl command, e.g. curl -v inventory-aws-application-ne-03449e711929f70b4.7d67968.vpc-lattice-svcs.eu-west-1.on.aws, it always responds with 503 service not available.

Any ideas how to debug what is going wrong?

You may want to double check if security group is configured correctly. Can you check the flowlog and see if anything is dropped due to security group?

Recreated the cluster from scratch and got it working. Thanks for help!

Found out what was the root cause. If the EKS cluster has the VPC CNI plugin installed, it results in Service not Available when checking service connectivity.
