部署 istio

1.添加 istio 官方的 helm 仓库

helm repo add istio   https://storage.googleapis.com/istio-release/releases/1.3.3/charts/

2.是否添加成功

helm search repo istio

NAME CHART VERSION APP VERSION DESCRIPTION
istio/istio 1.3.3 1.3.3 Helm chart for all istio components
istio/istio-cni 1.3.3 1.3.3 Helm chart for istio-cni components
istio/istio-init 1.3.3 1.3.3 Helm chart to initialize Istio CRDs

3.创建 istio-system 命名空间

kubectl create ns istio-system

4.创建 istio 所需的 crd 文件

helm install istio-init istio/istio-init -n istio-system

5.检查 CRD 文件是否创建完成,输出为23

kubectl get crds | grep 'istio.io' | wc -l

23
