Created a Vault and Consul cluster on Kubernetes with TLS by following
https://testdriven.io/blog/running-vault-and-consul-on-kubernetes/ and was trying to configure Kubernetes auth method using https://learn.hashicorp.com/vault/identity-access-management/vault-agent-k8s everything went fine up to step 3 (Verify the Kubernetes auth method configuration), when I tested connection I am getting the error "Failed to connect to vault port 8200: Connection refused". Can any one help me with this.

$ kubectl run --generator=run-pod/v1 tmp --rm -i --tty --serviceaccount=vault-auth --image alpine:3.7
