Argo CD自动同步Push请求

资源列表

操作系统	配置	主机名	IP	所需软件
CentOS 7.9	2C4G	master	192.168.93.145	Docker Ce、kube-apiserver、kube-controller-manager、kube-scheduler、kubelet、Etcd、kube-proxy

CentOS 7.9	2C4G	gitlab	192.168.93.102	GtiLab

一、创建Gitlba仓库

• 创建的仓库是用来存放Kubernetes的资源清单

1.1、创建仓库

1.2、编写资源清单

[root@gitlab ~]# git clone http://192.168.93.102/root/argocd-test.git
[root@gitlab ~]# cd argocd-test/

# 准备所需资源(测试)
[root@gitlab argocd-test]# cat deployment.yaml 
apiVersion: "apps/v1"
kind: Deployment
metadata:name: argocd-deploymentlabels:app: argocd
spec:replicas: 3selector:matchLabels:app: argocdtemplate:metadata:labels:app: argocdspec:containers:- name: nginximage: nginx:latestimagePullPolicy: IfNotPresentports:- containerPort: 80[root@gitlab argocd-test]# cat service.yaml 
apiVersion: "v1"
kind: Service
metadata:name: argocd-nginxlabels:app: argocd
spec:selector:app: argocdtype: NodePortports:- port: 80protocol: TCPtargetPort: 80nodePort: 30007

# 提交代码至仓库中
[root@gitlab argocd-test]# git add .
[root@gitlab argocd-test]# git commit -m "v1"
[root@gitlab argocd-test]# git push -u origin

二、创建Application

• 仓库Argo CD资源
  
  

三、设置GitLab的Webhook

• 设置触发Push请求

3.1、设置Web Hook

3.2、配置Argo CD Secret

[root@master ~]# kubectl edit secret -n argocd argocd-secret
# Please edit the object below. Lines beginning with a '#' will be ignored,
# and an empty file will abort the edit. If an error occurs while saving this file will be
# reopened with the relevant failures.
#
apiVersion: v1
stringData:# gitlab webhook secretwebhook.gitlab.secret: wzh

3.3、配置Web Hook

# 调用的Argo CD是域名所以要在 gitlab 主机做hosts解析
[root@gitlab argocd-test]# cat /etc/hosts | tail -1
192.168.93.146 argocd.devops-engineer.com.cn

• URL填写Argo CD API接口：https://argocd.devops-engineer.com.cn/api/webhook
• Secret Token：填写上面加入的数字123
• Trigger：提交到什么分支会发送push请求（main）
  
  

3.4、测试webhook

# 提前监控 Argo CD服务是否有接收push请求（添加上面hook确定之后）
[root@master ~]# kubectl logs -f -n argocd argocd-server-b6b977d99-4kp5r
time="2024-12-22T03:30:44Z" level=info msg="Received push event repo: http://192.168.93.102/root/argocd-test, revision: main, touchedHead: true"
time="2024-12-22T03:30:44Z" level=info msg="Requested app 'argocd-push' refresh"

3.5、更改仓库yaml字段

• 更改image镜像，然后快速回到Argo CD即可看到效果
  
  

• 点击其中一个即可
