Kubernetes Istio从1.4升级到1.5

通过在k8s cluster-1.15.1上运行以下命令，我们已经从istio-demo.yml文件安装了istion-1.4.0

kubectl apply-f istio-demo.yml

现在，我们需要将我们的istio从1.4.0升级到1.5.0，据我所知，由于istio组件的变化（引入istiod并移除城堡、厨房、政策和遥测系统），这不是直接的

---

我如何才能从kubectl升级到istoctl，以便我将来升级到iSto时与之保持一致？

正如我在评论中提到的，我遵循了关于创建升级的主题by@laurentiuspurba.

我已经为您的用例做了一些修改，所以从1.4升级到1.5

请看下面要遵循的步骤

---

1.遵循istio并安装istioctl 1.4和1.5，包括：

curl -L https://istio.io/downloadIstio | ISTIO_VERSION=1.4.0 sh -
curl -L https://istio.io/downloadIstio | ISTIO_VERSION=1.5.0 sh -

2.将istioctl 1.4添加到路径中

cd istio-1.4.0
export PATH=$PWD/bin:$PATH

cd istio-1.5.0
export PATH=$PWD/bin:$PATH

3.安装istio 1.4

istioctl manifest generate > $HOME/generated-manifest.yaml
kubectl create namespace istio-system
kubectl apply -f generated-manifest.yaml

4.检查是否一切正常

kubectl get pod -n istio-system
kubectl get svc -n istio-system
istioctl version

kubectl get pod -n istio-system
kubectl get svc -n istio-system
istioctl version

5.将istioctl 1.5添加到路径中

cd istio-1.4.0
export PATH=$PWD/bin:$PATH

cd istio-1.5.0
export PATH=$PWD/bin:$PATH

6.安装以备将来升级

istioctl operator init

7.准备IstioOperator.yaml

nano IstioOperator.yaml

istioctl upgrade -f IstioOperator.yaml 

---

8.升级前，请使用以下命令

kubectl -n istio-system delete service/istio-galley deployment.apps/istio-galley
kubectl delete validatingwebhookconfiguration.admissionregistration.k8s.io/istio-galley

kubectl -n istio-system delete deployment istio-citadel istio-galley istio-pilot istio-policy istio-sidecar-injector istio-telemetry
kubectl -n istio-system delete service istio-citadel istio-policy istio-sidecar-injector istio-telemetry
kubectl -n istio-system delete horizontalpodautoscaler.autoscaling/istio-pilot horizontalpodautoscaler.autoscaling/istio-telemetry
kubectl -n istio-system delete pdb istio-citadel istio-galley istio-pilot istio-policy istio-sidecar-injector istio-telemetry
kubectl -n istio-system delete deployment istiocoredns
kubectl -n istio-system delete service istiocoredns

9.使用istioctl升级和准备的IstioOperator.yaml从1.4升级到1.5

nano IstioOperator.yaml

istioctl upgrade -f IstioOperator.yaml 

10.升级后，使用以下命令

kubectl -n istio-system delete service/istio-galley deployment.apps/istio-galley
kubectl delete validatingwebhookconfiguration.admissionregistration.k8s.io/istio-galley

kubectl -n istio-system delete deployment istio-citadel istio-galley istio-pilot istio-policy istio-sidecar-injector istio-telemetry
kubectl -n istio-system delete service istio-citadel istio-policy istio-sidecar-injector istio-telemetry
kubectl -n istio-system delete horizontalpodautoscaler.autoscaling/istio-pilot horizontalpodautoscaler.autoscaling/istio-telemetry
kubectl -n istio-system delete pdb istio-citadel istio-galley istio-pilot istio-policy istio-sidecar-injector istio-telemetry
kubectl -n istio-system delete deployment istiocoredns
kubectl -n istio-system delete service istiocoredns

11.检查是否一切正常

kubectl get pod -n istio-system
kubectl get svc -n istio-system
istioctl version

kubectl get pod -n istio-system
kubectl get svc -n istio-system
istioctl version

12.我部署了一个bookinfo应用程序来检查是否一切正常

kubectl label namespace default istio-injection=enabled
kubectl apply -f samples/bookinfo/platform/kube/bookinfo.yaml
kubectl apply -f samples/bookinfo/networking/bookinfo-gateway.yaml

13.结果

curl -v xx.xx.xxx.xxx/productpage | grep HTTP
HTTP/1.1 200 OK


istioctl version
client version: 1.5.0
control plane version: 1.5.0
data plane version: 1.5.0 (8 proxies)

希望你觉得这个有用。如果您有任何问题，请告诉我。

您的问题是什么？具体来说，@Rico。。我已经起草了查询，没有几行被遗漏。我不确定我是否理解正确，您正在寻找一种方法来安装

istioctl

，并使用它安装istio，或者使用

kubectl apply

升级您的istio构建？如果它是关于升级的，我怀疑它可能会像helm一样工作，istio上有社区指南，您可以尝试安装并遵循从1.4.x到1.4.10和从1.4.10到1.5.x的步骤吗？
