argocd 之部署

argo CD _v2.13.3 是一个遵循gitops 理念的持续交付工具,支持对多k8s集群执行部署

kubectl create namespace argocd
kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

[root@master01 ~]# kubectl get pod -n argocd 
NAME                                                READY   STATUS    RESTARTS   AGE

查看初始化密码

kubectl -n argocd get secret  argocd-initial-admin-secret -ojsonpath='{.data.password}'|base64 -d

支持通过ui 界面和argocd 命令操作

• 通过argocd 命令操作

  wget https://github.com/argoproj/argo-cd/releases/download/v2.13.3/argocd-linux-amd64 -O /usr/bin/argocd
  chmod +x /usr/bin/argocd

  [root@master01 ~]#  kubectl get svc -n argocd argocd-server 
  NAME            TYPE       CLUSTER-IP       EXTERNAL-IP   PORT(S)                      AGE
  argocd-server   NodePort   172.168.227.98   <none>        80:32322/TCP,443:30534/TCP   71m

  登录argocd

  [root@master01 ~]# argocd login argocd-server
  FATA[0000] dial tcp: lookup argocd-server on 192.168.0.1:53: no such host 
  [root@master01 ~]# argocd login  172.168.227.98
  WARNING: server certificate had error: tls: failed to verify certificate: x509: cannot validate certificate for 172.168.227.98 because it doesn't contain any IP SANs. Proceed insecurely (y/n)? y

  更新密码

  argocd account update-password

  部署一个demo

  1. 将名称空间从default 切换到 argocd

     kubectl config set-context --current --namespace=argocd

  2. 部署应用

     https://github.com/argoproj/argocd-example-apps.git

     argocd app create guestbook \
     --repo https://gitee.com/mingtian66/argocd-example-apps.git   \
     --path guestbook \
     --dest-server https://kubernetes.default.svc \
     --dest-namespace test

  3. 查看app 状态，当前应用并未部署。处于OutOfSync 状态

     argocd app get  guestbook 

  4. 执行部署,该命令从git 仓库获取清单并执行kubectl apply 动作

     argocd app sync guestbook

  5. 销毁app

     argocd app delete guestbook

• 通过ui界面操作
