kubectl create namespace argocd kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml
暴露服务：通过service的nodeport即可
~]# kubectl get svc -n argocd -l app.kubernetes.io/name=argocd-server NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE argocd-server NodePort 10.43.49.210 <none> 80:31207/TCP,443:32407/TCP 23h
下载命令行工具：
https://github.com/argoproj/argo-cd/releases/tag/v2.5.2 wget https://github.com/argoproj/argo-cd/releases/download/v2.5.2/argocd-linux-amd64 mv argocd-linux-amd64 /usr/local/bin/argocd chmod +x /usr/local/bin/argocd echo "source <(argocd completion bash)" >> ~/.bashrc . ~/.bashrc
获取密码：
kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d; echo登陆：
argocd login 192.168.199.80:32407
更新密码：
argocd account update-password
打开web页面：即可用刚刚修改的密码登录

argo rollouts
部署arogo rollouts：
文档：
https://argoproj.github.io/argo-rollouts/installation/
创建名称空间：
kubectl create namespace argo-rollouts kubectl apply -n argo-rollouts -f https://github.com/argoproj/argo-rollouts/releases/latest/download/install.yaml
查看Pod：
]# kubectl get pods -n argo-rollouts NAME READY STATUS RESTARTS AGE argo-rollouts-f7fc79848-rxql9 1/1 Running 0 78s
生成的crd：

下载命令：
https://github.com/argoproj/argo-rollouts/releases
安装命令：
wget https://github.com/argoproj/argo-rollouts/releases/download/v1.3.1/kubectl-argo-rollouts-linux-amd64 chmod +x /usr/local/bin/argo-rollouts
命令调用方式：两种都可以
]# kubectl argo rollouts ]# rgo-rollouts
部署dashboard：在下载命令的地址中有部署文件。
kubectl apply -n argo-rollouts -f https://github.com/argoproj/argo-rollouts/releases/download/v1.3.1/dashboard-install.yaml
查看Pod：
]# kubectl get pods -n argo-rollouts NAME READY STATUS RESTARTS AGE argo-rollouts-dashboard-655b9b6ccb-9zn57 1/1 Running 0 45s argo-rollouts-f7fc79848-rxql9 1/1 Running 0 23m
暴露服务：然后就可以访问dashboard的web页面了
