GKE ingress in a nutshell

• https://medium.com/google-cloud/ingress-in-google-kubernetes-products-f22ded21f4ed

Solution #1 (ManagedCertificate CRD in GKE)

• GKE with Google-managed SSL certificates
  • Use ManagedCertificate CRD to create a object.
  • Associate the ManagedCertificate object to an Ingress by adding an annotation networking.gke.io/managed-certificates to the Ingress. This annotation is a comma-separated list of ManagedCertificate resources, cert1,cert2,cert3 for example.

Solution #2 (Google Cloud SSL Certificate)

Assumption

# Initially client side certificates where created during
# image cooking, but soon figured out it would not work in 
# the long run. When I changed it to post provision execution
# I found errors that mentioned certificates already existed
# and found the issue described in GitHub.
