Istio 部署没有发生

Question

我正在尝试在 minikube 集群中安装 istio

我按照这个页面上的教程https://istio.io/docs/setup/kubernetes/quick-start/

我正在尝试使用选项 1：https://istio.io/docs/setup/kubernetes/quick-start/#option-1-install-istio-without-mutual-tls-authentication-between-sidecars

我可以看到服务已经创建，但是部署似乎失败了。

kubectl get pods -n istio-system 
No resources found

我该如何解决这个问题？

这是get部署的结果

kubectl get deployment -n istio-system

这对我有用。启动 minikube 时不要使用 --extra-configs。这导致 kube-controller-manager-minikube 崩溃，因为它无法找到文件

错误启动控制器：未能启动证书控制器： 读取 CA 证书文件“/var/lib/localkube/certs/ca.crt”时出错：打开 /var/lib/localkube/certs/ca.crt: 没有这样的文件或目录

只需使用此命令启动 minikube。我有 minikube V0.30.0。

minikube start

输出：

指向istio-1.0.4 folder，运行这个命令

kubectl apply -f install/kubernetes/helm/istio/templates/crds.yaml

这应该会安装所有必需的 crd

运行此命令

kubectl apply -f install/kubernetes/istio-demo.yaml

成功创建规则、服务、部署等后，运行此命令

 kubectl get pods -n istio-system

还可以尝试自定义安装via Helm template。您不需要为此部署 Tiller。

1) kubectl apply -f install/kubernetes/helm/istio/templates/crds.yaml

2) helm template install/kubernetes/helm/istio --name istio --namespace istio-system --set grafana.enabled=true --set servicegraph.enabled=true --set tracking.enabled=true -- set kiali.enabled=true --set sidecarInjectorWebhook.enabled=true --set global.tag=1.0.5 > $HOME/istio.yaml

3) kubectl 创建命名空间 istio-system

4) kubectl apply -f $HOME/istio.yaml
