部署 istio
1.添加 istio 官方的 helm 倉庫
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.創建 istio-system 命名空間
kubectl create ns istio-system
4.創建 istio 所需的 crd 檔案
helm install istio-init istio/istio-init -n istio-system
5.檢查 CRD 檔案是否創建完成，輸出為23
kubectl get crds | grep 'istio.io' | wc -l
23
6.部署 istio
helm install istio istio/istio -n istio-system
NAME: istio
LAST DEPLOYED: Thu Oct 24 12:05:06 2019
NAMESPACE: istio-system
STATUS: deployed
REVISION: 1
NOTES:
Thank you for installing Istio.Your release is named Istio.
To get started running application with Istio, execute the following steps:
- Label namespace that application object will be deployed to by the following command (take default namespace as an example)
kubectl label namespace default istio-injection=enabled
? kubectl get namespace -L istio-injection
- Deploy your applications
$ kubectl apply -f
.yaml For more information on running Istio, visit:

卸載 istio
1.卸載 istio
helm -n istio-system uninstall istio
2.洗掉 istio crd 檔案
helm -n istio-system uninstall istio-init
kubectl delete crd `kubectl get crd | grep istio| awk '{print $1}'`
一鍵部署及卸載 istio 的腳本
部署腳本
#!/bin/bash
# Add istio official repo
add_repo(){
VERSION=$1
REPO="https://storage.googleapis.com/istio-release/releases/${VERSION}/charts/"
helm repo add istio $REPO
STATUS_CMD=`echo $?`
CHECK_REPO_CMD=`helm repo list | grep $REPO | wc -l`
echo "$STATUS_CMD"
echo "$CHECK_REPO_CMD"
while [[ $STATUS_CMD != 0 && $CHECK_REPO_CMD -ge 1 ]]
do
sleep 5
helm repo add istio $REPO
STATUS_CMD=`echo $?`
CHECK_REPO_CMD=`helm repo list | grep $REPO | wc -l`
done
}
# Create istio-system namespace
create_namespace() {
NAMESPACE=$1
kubectl create ns ${NAMESPACE}
STATUS_CMD=`echo $?`
while [[ $STATUS_CMD != 0 ]]
do
sleep 5
kubectl create ns ${NAMESPACE}
STATUS_CMD=`echo $?`
done
}
# Create CRD need for istio
create_crd() {
NAMESPACE=$1
helm install istio-init istio/istio-init -n ${NAMESPACE}
CRD_COUNT=`kubectl get crds | grep 'istio.i' | wc -l`
while [[ ${CRD_COUNT} != 23 ]]
do
sleep 5
CRD_COUNT=`kubectl get crds | grep 'istio.io' | wc -l`
done
echo 'Istio crd create successful'
}
# Deploy istio related components
deploy_istio() {
NAMESPACE=$1
VERSION=$2
helm install istio istio/istio -n ${NAMESPACE}
check() {
kubectl -n ${NAMESPACE} get deploy | grep istio | awk '{print "deployment/"$1}' | while read line ;
do
kubectl rollout status $line -n ${NAMESPACE};
done
}
check
echo "Istio is deployed successful"
}
main(){
ISTIO_VERSION="1.3.3"
ISTIO_NAMESPACE="istio-system"
add_repo $ISTIO_VERSION
if [[ `kubectl get ns | grep $ISTIO_NAMESPACE | wc -l ` == 0 && `kubectl get ns $ISTIO_NAMESPACE | grep -v NAME | wc -l` == 0 ]] ;then
create_namespace $ISTIO_NAMESPACE
fi
create_crd $ISTIO_NAMESPACE
deploy_istio $ISTIO_NAMESPACE $ISTIO_VERSION
}
main
卸載腳本
#!/bin/bash
helm -n istio-system uninstall istio
helm -n istio-system uninstall istio-init
kubectl delete crd `kubectl get crd | grep istio | awk '{print $1}'`
kubectl delete ns istio-system
注意：卸載需謹慎，洗掉了 istio-system 的命名空間

- 點擊查看我的個人Blog
- 日拱一卒，不期速成
上述步驟使用的是 istio 官方提供的默認配置，如果你想要自定配置，可以閱讀 values.yaml 檔案后，通過 --set 的方式修改，或者直接修改 chart，
