argocd

官网：
https://argo-cd.readthedocs.io/en/stable/#getting-started

整体发布流程如图所示
用户提交应用发布文件（k8s manifest yaml / helm / kustomize 等）到 git 仓库（gitlab/github 等）
argocd 监听 git 仓库的文件变化，根据配置手动或者自动把应用发布文件同步变更到 k8s 集群中

在这里插入图片描述

创建名称空间，下载yaml文件

kubectl create ns argo
//在安装yaml文件的目录下，执行
kubectl apply -n argo -f .

本地访问Argocd

我们将 argo-ui 改成 NodePort 类型的 Service（当然也可以创建 Ingress 对象通过域名进行访问、port_forward等方式）

// 查看 argocd 默认密码（argocd 1.9 以后的版本，参考：https://argoproj.github.io/argo-cd/faq/#i-forgot-the-admin-password-how-do-i-reset-it）
# kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d

// 更改 admin 密码
