centos k8s安装dapr

---

安装helm

三个包放到一个目录下

chmod +x get
./get
helm version

更新helm库

helm repo add dapr https://dapr.github.io/helm-charts/
helm repo update
helm search repo dapr --devel --versions #查看可以安装那些版本的

初始化dapr

# test-dapr是k8s的命名空间
helm install dapr dapr/dapr --namespace test-dapr --wait

helm upgrade --install dapr dapr/dapr \
--version=1.2 \
--namespace test-dapr \
--create-namespace \
--wait

高可用方式安装

helm upgrade --install dapr dapr/dapr \
--version=1.2 \
--namespace test-dapr \
--create-namespace \
--set global.ha.enabled=true \
--wait

卸载dapr

helm uninstall dapr --namespace test-dapr

验证

kubectl -n test-dapr get pods 

它还有页面，但是svc那要增加一个，把那个cluster修改为NodePort方式

k8s的dapr安装rocketmq
