Kubernetes 使用Istio OCTL和Istio运算符升级Istio 1.4.3至1.5.6

我是否可以使现有的Istio开放源码安装程序与（Istioctl+运算符）兼容？我目前通过istioctl安装了Istio 1.4.3。。在升级到Istio 1.5.6+之前，还需要让现有的部署Istio操作员知道。这里有什么具体的步骤需要遵循吗？

这应该不会有任何问题，我已经在我的测试集群上尝试过了，一切都很好

我在立即从1.4.3升级到1.5.6时遇到问题，因此通过以下步骤，您首先从1.4.3升级到1.5.0，然后从1.5.0升级到1.5.6

请看下面要遵循的步骤

---

1.遵循istio并安装istioctl 1.4、1.5和1.5.6，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 -
curl -L https://istio.io/downloadIstio | ISTIO_VERSION=1.5.6 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

cd istio-1.5.6
export PATH=$PWD/bin:$PATH

3.安装istio 1.4

istioctl manifest apply --set profile=demo

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

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

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

cd istio-1.5.6
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 

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 

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

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

12.更改istio IstioOperator.yaml标记值

---

14.将istioctl 1.5.6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

cd istio-1.5.6
export PATH=$PWD/bin:$PATH

15.我部署了一个bookinfo应用程序来检查是否一切正常

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

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

16.结果

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


istioctl version
client version: 1.5.6
control plane version: 1.5.6
data plane version: 1.5.6 (9 proxies)
