I am trying to my spring boot micro service in GKE Cluster with istio 1.1.5 latest version as of now. It throws error and pod never spins up. If I run it as a separate service in Kubernetes engine it works perfectly but with isito, it does not work. The purpose for using istio is to host multiple microservices and to use the feature istio provides. Here is my yaml file:
apiVersion: apps/v1beta1
kind: Deployment
metadata:
name: revenue
spec:
replicas: 1
template:
metadata:
labels:
app: revenue-serv
tier: backend
track: stable
spec:
containers:
- name: backend
image: "gcr.io/finacials/revenue-serv:latest"
imagePullPolicy: Always
ports:
- containerPort: 8081
livenessProbe:
httpGet:
path: /
port: 8081
initialDelaySeconds: 15
timeoutSeconds: 30
readinessProbe:

I have found the issue. I removed readynessProbe and livenessProbe and created ingressgateway and virtual service. It worked.
