使用 Helm Chart 部署及卸载 istio
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
6.部署 istio
helm install istio istio/istio -n istio-system
