A Fabrikate component that encapsulates the reuseable portions of a tiered Istio service deployment, including VirtualService, Service, Deployment, and DestinationRule.
From your Fabrikate definition at the level at which you'd like to add a service subcomponent, use fab add to add fabrikate-istio-service for your microservice:
$ fab add my-service --source https://github.com/timfpark/fabrikate-istio-service
then create a deployment config for each of your environments with one or more tiers. For example, a prod deployment config with canary and stable tiers would live in config/prod.yaml looks like this:
subcomponents:
my-service:
namespace: services
config:
gateway: my-ingress.istio-system.svc.cluster.local
service:
dns: myservice.mycompany.io
name: my-service
port: 80
configMap:
LOG_SEVERITY: "info"
PORT: "80"
