Centos7下k8s集群里初始化Dapr
Centos7下k8s集群里初始化Dapr
以下步骤均在k8s的master节点执行
1、安装Dapr Cli
Dapr CLI 允许您在本地开发机或Kubernetes集群上安装Dapr。 提供调试支持，启动和管理 Dapr 实例。
1、下载安装包到指定目录(机器可以访问外网)
wget -q https://raw.githubusercontent.com/dapr/cli/master/install/install.sh -O - | /bin/bash
2、验证结果
dapr -v
以下结果为正确安装
[root@master linux-amd64]# dapr -v
CLI version: 1.8.1
Runtime version: n/a
2、安装Helm3
Helm是一个K8S的包管理工具，就像Linux下的包管理器，如yum/apt等，可以很方便的将之前打包好的yaml文件部署到K8S上。
1、下载压缩包
wget http://k8schina.corecore.cn/helm-v3.8.0-linux-amd64.tar.gz
2、解压并复制到对应目录
tar -zxvf helm-v3.8.0-linux-amd64.tar.gz
cp ./linux-amd64/helm /usr/local/bin/
3、验证是否安装成功
helm version
出现一下界面则认为安装成功
[root@master ~]# helm version
version.BuildInfo{Version:"v3.8.0", GitCommit:"d14138609b01886f544b2025f5000351c9eb092e", GitTreeState:"clean", GoVersion:"go1.17.5"}
3、初始化Dapr集群
1、增加helm repo 并update
helm repo add stable http://mirror.azure.cn/kubernetes/charts
helm repo add aliyuncs https://apphub.aliyuncs.com
helm repo add dapr https://dapr.github.io/helm-charts/
helm repo update
2、查看dapr helm repo
helm search repo dapr --devel --versions
如果仓库设置正确，则会出现很多安装版本
[root@master ~]# helm search repo dapr --devel --versions
NAME CHART VERSION APP VERSION DESCRIPTION
dapr/dapr 1.8.4 1.8.4 A Helm chart for Dapr on Kubernetes
dapr/dapr 1.8.3 1.8.3 A Helm chart for Dapr on Kubernetes
dapr/dapr 1.8.2 1.8.2 A Helm chart for Dapr on Kubernetes
dapr/dapr 1.8.1 1.8.1 A Helm chart for Dapr on Kubernetes
dapr/dapr 1.8.0 1.8.0 A Helm chart for Dapr on Kubernetes
dapr/dapr 1.8.0-rc.8 1.8.0-rc.8 A Helm chart for Dapr on Kubernetes
dapr/dapr 1.8.0-rc.7 1.8.0-rc.7 A Helm chart for Dapr on Kubernetes
dapr/dapr 1.8.0-rc.6 1.8.0-rc.6 A Helm chart for Dapr on Kubernetes
dapr/dapr 1.8.0-rc.5 1.8.0-rc.5 A Helm chart for Dapr on Kubernetes
dapr/dapr 1.8.0-rc.4 1.8.0-rc.4 A Helm chart for Dapr on Kubernetes
dapr/dapr 1.8.0-rc.3 1.8.0-rc.3 A Helm chart for Dapr on Kubernetes
dapr/dapr 1.8.0-rc.2 1.8.0-rc.2 A Helm chart for Dapr on Kubernetes
3、创建dapr的命名空间
kubectl create namespace dapr-system
4、在对应的命名空间内初始化dapr
helm install dapr dapr/dapr --namespace dapr-system --wait
等待出现一下提示信息则认为安装成功
[root@master ~]# helm install dapr dapr/dapr --namespace dapr-system --wait
NAME: dapr
LAST DEPLOYED: Mon Aug 15 10:56:49 2022

如果要卸载dapr则
helm uninstall dapr --namespace dapr-system
4、验证
查看k8s下的pod是否完全启动
kubectl get pods --namespace dapr-system
以下为正确启动
[root@master ~]# kubectl get pods --namespace dapr-system
NAME READY STATUS RESTARTS AGE
dapr-dashboard-58c4b748fc-9tngf 1/1 Running 0 14m
dapr-operator-7dcdd6d9f4-99t4p 1/1 Running 4 14m
dapr-placement-server-0 1/1 Running 4 14m
dapr-sentry-866d974f9c-59b5g 1/1 Running 4 14m
dapr-sidecar-injector-56798bbddf-qwdp4 1/1 Running 5 14m
查看dapr集群状态
dapr status -k
以下为正确启动
[root@master linux-amd64]# dapr status -k
