安装Helm

根据官方文档介绍，选择对应的安装方式。
1、二进制版本安装
2、包管理器安装（比如brew install kubernetes-helm）
3、脚本安装

  1. # 确认helm版本
  2. root@master:~# helm version
  3. version.BuildInfo{Version:"v3.0.3", GitCommit:"ac925eb7279f4a6955df663a0128044a8a6b7593", GitTreeState:"clean", GoVersion:"go1.13.6"}

仓库初始化

  • helm search hub从Artifact Hub中查找并列出 helm charts。 Artifact Hub中存放了大量不同的仓库。
  • helm search repo从你添加（使用helm repo add）到本地 helm 客户端中的仓库中进行查找。该命令基于本地数据进行搜索，无需连接互联网。 ```bash

    添加一个公开repo

    [root@harbor ~]# helm repo add bitnami https://charts.bitnami.com/bitnami “bitnami” has been added to your repositories [root@harbor ~]# helm repo list NAME URL bitnami https://charts.bitnami.com/bitnami

查询当前repo的所有chart列表

[root@harbor ~]# helm search repo nginx NAME CHART VERSION APP VERSION DESCRIPTION bitnami/nginx 8.9.0 1.19.10 Chart for the nginx server bitnami/nginx-ingress-controller 7.6.6 0.46.0 Chart for the nginx Ingress controller bitnami/kong 3.7.0 2.4.0 Kong is a scalable, open source API layer (aka …

  2. ## 安装Chart
  4. helm install命令可以从多个来源进行安装：
  6. - chart 的仓库（如上所述）
  7. - 本地 chart 压缩包（helm install foo foo-0.1.1.tgz）
  8. - 解压后的 chart 目录（helm install foo path/to/foo）
  9. - 完整的 URL（helm install foo https://example.com/charts/foo-1.2.3.tgz）
  11. 使用helm install命令来安装一个新的 helm 包。最简单的使用方法只需要传入两个参数：你命名的release名字(或者--generate-name)和你想安装的chart的名称。
  12. ```bash
  13. # 查看chart基本信息
  14. [root@harbor ~]# helm show chart bitnami/nginx
