官网手册https://helm.sh/zh/docs/intro/quickstart/

先决条件：

1. 一个 Kubernetes 集群

2. 确定你安装版本的安全配置

3. 安装和配置Helm

helm安装

安装手册https://helm.sh/zh/docs/intro/install/

二进制安装（推荐）

1. 下载 需要的版本

2. 解压(tar -zxvf helm-v3.0.0-linux-amd64.tar.gz)

3. 在解压目录中找到helm程序，移动到需要的目录中(mv linux-amd64/helm /usr/local/bin/helm)

脚本安装

该脚本会自动拉取最新的Helm版本并在 本地安装

$ curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3
$ chmod 700 get_helm.sh
$ ./get_helm.sh

包安装

mac

brew install helm

windows

choco install kubernetes-helm

scoop install helm

winget install Helm.Helm

linux

apt

curl https://baltocdn.com/helm/signing.asc | gpg --dearmor | sudo tee /usr/share/keyrings/helm.gpg > /dev/null
sudo apt-get install apt-transport-https --yes
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/helm.gpg] https://baltocdn.com/helm/stable/debian/ all main" | sudo tee /etc/apt/sources.list.d/helm-stable-debian.list
sudo apt-get update
sudo apt-get install helm

yum

sudo dnf install helm

初始化

安装好了Helm之后，可以添加一个chart 仓库。从 Artifact Hub中查找有效的Helm chart仓库

helm repo add bitnami https://charts.bitnami.com/bitnami

当添加完成，您将可以看到可以被您安装的charts列表

[root@k8smaster ~]# helm repo list

安装Chart示例

您可以通过helm install 命令安装chart

[root@k8smaster ~]# helm repo  update bitnami
Hang tight while we grab the latest from your chart repositories...
...Successfully got an update from the "bitnami" chart repository
Update Complete. ⎈Happy Helming!⎈

[root@k8smaster ~]# helm install nfs-subdir-external-provisioner nfs-subdir-external-provisioner/nfs-subdir-external-provisioner     --set nfs.server=10.168.1.120     --set nfs.path=/data/k8s

[root@k8smaster ~]# helm show chart nfs-subdir-external-provisioner/nfs-subdir-external-provisioner
apiVersion: v1
appVersion: 4.0.2
description: nfs-subdir-external-provisioner is an automatic provisioner that used
  your *already configured* NFS server, automatically creating Persistent Volumes.
home: https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner
keywords:
- nfs
- storage
- provisioner
kubeVersion: '>=1.9.0-0'
name: nfs-subdir-external-provisioner
sources:
- https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner
version: 4.0.18

在上面的例子中nfs-subdir-external-provisioner/nfs-subdir-external-provisioner 这个chart被发布，名字是 nfs-subdir-external-provisioner

您可以通过执行 helm show chart nfs-subdir-external-provisioner/nfs-subdir-external-provisioner 命令简单的了解到这个chart的基本信息。 或者您可以执行 helm show all nfs-subdir-external-provisioner/nfs-subdir-external-provisioner 关于该chart的所有信息。

每当您执行 helm install 的时候，都会创建一个新的发布版本。 所以一个chart在同一个集群里面可以被安装多次，每一个都可以被独立的管理和升级。

操作基本命令
