We have been trying to Secure Gateways with SIMPLE TLS for our gRPC Backend which is deployed in Minikube for now by following this link.
We were able to successfully access the gRPC service over plaintext through Istio Ingress Gateway using grpcurl client.
But while we tried to use SIMPLE TLS, we have been experiencing -
ERROR:
Code: Unavailable
Message: upstream connect error or disconnect/reset before headers. reset reason: remote reset
Please find the steps -
- Created a certificate and a private key for sc-imcps-bootstrap-lb.example.com (Sample Domain for gRPC Server for Minikube)
- Create kubernetes secrets by following this command -
kubectl create -n istio-system secret tls sc-imcps-bootstrap-lb-credential --key=sc-imcps-bootstrap-lb.example.com.key --cert=sc-imcps-bootstrap-lb.example.com.crt
-
Created Gateway manifest. (kubectl apply -n foo -f gateway.yaml) [gateway.yaml is attached]
-
Configure the gateway’s traffic routes. by creating VirtualService definition [virtualservice.yaml is attached]
-
Client execution from host -
grpcurl -v -d ‘{“AppName”: “SC”, “AppVersion”: 1, “PID”: 8132, “ContainerID”: “asd-2”, “CloudInternal”: true}’ -cacert example.com.crt -proto imcps.proto sc-imcps-bootstrap-lb.example.com:443 imcps.IMCPS/Init
