I’m having a problem migrating my pure Kubernetes app to an Istio managed. I’m using Google Cloud Platform (GCP), Istio 1.4, Google Kubernetes Engine (GKE), Spring Boot and JAVA 11.
I had the containers running in a pure GKE environment without a problem. Now I started the migration of my Kubernetes cluster to use Istio. Since then I’m getting the following message when I try to access the exposed service.
upstream connect error or disconnect/reset before headers. reset reason: connection failure
This error message looks like a really generic. I found a lot of different problems, with the same error message, but no one was related to my problem.
Bellow the version of the Istio:
client version: 1.4.10 control plane version: 1.4.10-gke.5 data plane version: 1.4.10-gke.5 (2 proxies)
Bellow my yaml files:
apiVersion: v1 kind: ServiceAccount metadata: labels: account: tree-guest name: tree-guest-service-account --- apiVersion: v1 kind: Service metadata: labels: app: tree-guest service: tree-guest name: tree-guest spec: ports: - name: http port: 8080 targetPort: 8080 selector: app: tree-guest --- apiVersion: apps/v1 kind: Deployment metadata: labels: app: tree-guest version: v1 name: tree-guest-v1 spec: replicas: 1 selector: matchLabels: app: tree-guest version: v1 template: metadata: labels: app: tree-guestaz version: v1 spec: containers: - image: registry.hub.docker.com/victorsens/tree-quest:circle_ci_build_00923285-3c44-4955-8de1-ed578e23c5cf imagePullPolicy: IfNotPresent name: tree-guest ports: - containerPort: 8080 serviceAccount: tree-guest-service-account --- apiVersion: networking.istio.io/v1alpha3 kind: Gateway metadata: name: tree-guest-gateway spec: selector: istio: ingressgateway # use istio default controller servers: - port: number: 80 name: http protocol: HTTP hosts: - "*" --- apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: name: tree-guest-virtual-service spec: hosts: - "*" gateways: - tree-guest-gateway http: - match: - uri: prefix: /v1 route: - destination: host: tree-guest port: number: 8080
To apply the yaml file I used the following argument:
kubectl apply -f <(istioctl kube-inject -f ./tree-guest.yaml)
If someone have a tip about what is going wrong, please let me know. I’m stuck in this problem for a couple of days.
