GitOps实践之kubernetes安装argocd
1. 什么是argocd
1.Argo CD是Kubernetes的一个声明性GitOps持续交付工具。
2.应用程序定义、配置和环境应该是声明性的和版本控制的。应用程序部署和生命周期管理应自动化、可审核且易于理解。
3.Argo CD 是以 Kubernetes 作为基础设施，遵循声明式 GitOps 理念的持续交付（continuous delivery, CD）工具，支持多种配置管理工具，包括 ksonnet/jsonnet、kustomize 和 Helm 等。它的配置和使用非常简单，并且自带一个简单易用的可视化界面。
4.按照官方定义，Argo CD 被实现为一个 Kubernetes 控制器，它会持续监控正在运行的应用，并将当前的实际状态与 Git 仓库中声明的期望状态进行比较，如果实际状态不符合期望状态，就会更新应用的实际状态以匹配期望状态。
5.Argo CD 会被部署在 Kubernetes 集群中，使用的是基于 Pull 的部署模式，它会周期性地监控应用的实际状态，也会周期性地拉取 Git 仓库中的配置清单，并将实际状态与期望状态进行比较，如果实际状态不符合期望状态，就会更新应用的实际状态以匹配期望状态。

Username: admin
Password:
'admin:login' logged in successfully
Context '10.0.0.14' updated
