Unable to access API using hybrid runtime istio ingress gateway --- SSL error

[basavarajdhanas]

Hi All,

I was trying Apigee hybrid installation on GCP.

Installation is all success and I can see the proxy is been deployed to the runtime pods for the specific environment.

But I am unable to access the API through the Istio ingress gateway for APIs. I am getting below SSL error. SSL certificate pairs have been generated using lets-encrypt commands which were given in the documentation.

curl: (35) LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to api-qa.mydomain.in:443

Here is my configuration file:

gcp:
  projectID: gcp-project-id
# Apigee org name.
org: apigee-demo-trial-ou47h
# Kubernetes cluster name details
k8sCluster:
  name: apigee-demo-cluster
  region: "us-east1"


virtualhosts:
  - name: default
    hostAliases: 
        - "api-qa.mydomain.in"
    # either SSLSecret or the paths
    sslSecret: "qa-sslsecret"
    # Certificate for the domain name; this can be self signed.
    sslCertPath: /certs/fullchain.pem
    # Private key for the domain name; this can be self signed.
    sslKeyPath: ./certs/privkey.pem
    # optional
    routingRules:
      - env: qa
        paths: 
        - /myproxy  
        # optional, connect timeout in seconds
        connectTimeout: 57


envs:
    # Apigee environment name.
  - name: qa
    # Service accounts for sync and UDCA.
    serviceAccountPaths:
      synchronizer: ./service-accounts/gcp-project-id-apigee-synchronizer.json
      udca: ./service-accounts/gcp-project-id-apigee-udca.json

The first thing to check is that your domain (api-qa.mydomain.in) resolves to the external IP address on your GKE cluster (currently 199.59.242.153 - reverse resolves to bodis.com, not googleusercontent.com).

The error that is reported indicates that nothing is listening on that address.

In fact, I took the time to scan the host, and I did not see that any services are being hosted on that IP address.

a mistake in my override file only. Its working after correcting the file.

Either use K8S secret or use SSL certificate pair path.

Corrected contents:

gcp:
  projectID: gcp-project-id
# Apigee org name.
org: apigee-demo-trial-ou47h
# Kubernetes cluster name details
k8sCluster:
  name: apigee-demo-cluster
  region: "us-east1"


virtualhosts:
  - name: default
    hostAliases: 
        - "api-qa.mydomain.in"

    # Certificate for the domain name; this can be self signed.
    sslCertPath: /certs/fullchain.pem
    # Private key for the domain name; this can be self signed.
    sslKeyPath: ./certs/privkey.pem
    # optional
    routingRules:
      - env: qa
        paths: 
        - /myproxy  
        # optional, connect timeout in seconds
        connectTimeout: 57


envs:
    # Apigee environment name.
