istio 无法安装在通过 AWS 中的 Kops 构建的 Kubernetes 集群中

Question

I can't get the demo profile to work with istioctl. It seems like istioctl is having trouble creating IngressGateway and the AddonComponents. I have tried doing the helm installation with similar issues. I did a fresh k8s cluster from kops and the same issue. Any help debugging this issue would be greatly appreciated.

I am following these instructions. https://istio.io/docs/setup/getting-started/#download

I am running

 istioctl manifest apply --set profile=demo --logtostderr

This is the output

I ran the below to verify install before running the above commands.

istioctl verify-install

Checking the cluster to make sure it is ready for Istio installation...

#1. Kubernetes-api
-----------------------
Can initialize the Kubernetes client.
Can query the Kubernetes API Server.

#2. Kubernetes-version
-----------------------
Istio is compatible with Kubernetes: v1.16.7.

#3. Istio-existence
-----------------------
Istio will be installed in the istio-system namespace.

#4. Kubernetes-setup
-----------------------
Can create necessary Kubernetes configurations: Namespace,ClusterRole,ClusterRoleBinding,CustomResourceDefinition,Role,ServiceAccount,Service,Deployments,ConfigMap. 

#5. SideCar-Injector
-----------------------
This Kubernetes cluster supports automatic sidecar injection. To enable automatic sidecar injection see https://istio.io/docs/setup/kubernetes/additional-setup/sidecar-injection/#deploying-an-app

As mentioned in your logs

2020-04-06T19:59:24.951136Z info Detected that your cluster does not support third party JWT authentication. Falling back to less secure first party JWT.

As mentioned here

To determine if your cluster supports third party tokens, look for the TokenRequest API:

$ kubectl get --raw /api/v1 | jq '.resources[] | select(.name | index("serviceaccounts/token"))'
{
    "name": "serviceaccounts/token",
    "singularName": "",
    "namespaced": true,
    "group": "authentication.k8s.io",
    "version": "v1",
    "kind": "TokenRequest",
    "verbs": [
        "create"
    ]
}

While most cloud providers support this feature now, many local development tools and custom installations may not. To enable this feature, please refer to the Kubernetes documentation .

---

To authenticate with the Istio control plane, the Istio proxy will use a Service Account token. Kubernetes supports two forms of these tokens:

Third party tokens, which have a scoped audience and expiration. First party tokens, which have no expiration and are mounted into all pods. Because the properties of the first party token are less secure, Istio will default to using third party tokens. However, this feature is not enabled on all Kubernetes platforms.

If you are using istioctl to install, support will be automatically detected. This can be done manually as well, and configured by passing --set values.global.jwtPolicy=third-party-jwt or --set values.global.jwtPolicy=first-party-jwt.

---

If that won't work I would open a new github issue, or add a comment here as issue with installation is similar.
