未发生Istio部署

Question

我正在尝试在minikube集群中安装istio

我遵循了这个页面上的教程https://istio.io/docs/setup/kubernetes/quick-start/

我尝试使用选项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

如何对此进行故障排除？

以下是get部署的结果

kubectl get deployment -n istio-system

这就是对我有效的方法。不要在启动minikube时使用--extra-config%s。这是崩溃的kube-controller-manager-minikube，因为它不能找到文件

启动控制器时出错:无法启动证书控制器:读取CA证书文件“/var/lib/localkube/certs/ca.crt”时出错: open /var/lib/localkube/certs/ca.crt:没有这样的文件或目录

只需使用以下命令启动minikube。我有minikube V0.30.0。

minikube start

输出：

指向istio-1.0.4 folder，运行以下命令

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

这应该会安装所有需要的crds

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，运行以下命令

 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应用-f install/kubernetes/helm/istio/templates/crds.yaml

2) helm模板安装/kubernetes/helm/ istio --名称istio--命名空间istio--设置grafana.enabled=true --设置servicegraph.enabled=true --设置tracing.enabled=true --设置kiali.enabled=true --设置sidecarInjectorWebhook.enabled=true --设置global.tag=1.0.5 > $HOME/istio.yaml

3) kubectl创建命名空间istio-system

4) kubectl应用-f $HOME/istio.yaml
