Kubernetes精讲之包管理Helm工具

Helm是Kubernetes 应用的包管理工具，主要用来管理 Charts，类似Linux系统的yum。
Helm Chart是用来封装Kubernetes原生应用程序的一系列YAML文件。可以在你部署应用的时候自定义应用程序的一些 Metadata，以便于应用程序的分发。
对于应用发布者而言
通过Helm打包应用、管理应用依赖关系、管理应用版本并发布应用到软件仓库。
对于使用者而言
使用Helm后可以以简单的方式在Kubernetes上查找、安装、升级、回滚、卸载应用程序

二部署helm

2.1 官网与资源

官网： Helm | 快速入门指南

软件资源： https://github.com/helm/helm/releases

2.2部署helm

2.2.1 安装helm

[root@K8s-master ~]# mkdir helm
[root@K8s-master ~]# cd helm/

[root@k8s-master helm]# tar zxf helm-v3.15.4-linux-amd64.tar.gz
[root@k8s-master helm]# ls
helm-v3.15.4-linux-amd64.tar.gz  linux-amd64
[root@k8s-master helm]# cd  linux-amd64/
[root@k8s-master linux-amd64]# ls
helm  LICENSE  README.md
[root@k8s-master linux-amd64]# cp -p helm  /usr/local/bin/

2.2.2 配置helm命令补齐

[root@k8s-master linux-amd64]#  echo "source <(helm completion bash)" >> ~/.bashrc
[root@k8s-master linux-amd64]# source   ~/.bashrc
[root@k8s-master linux-amd64]# helm version
version.BuildInfo{Version:"v3.15.4", GitCommit:"fa9efb07d9d8debbb4306d72af76a383895aa8c4", GitTreeState:"clean", GoVersion:"go1.22.6"}

三 helm常用操作

命令	描述
create	创建一个 chart 并指定名字
dependency	管理 chart 依赖
get	下载一个 release。可用子命令：all、hooks、manifest、notes、values
history	获取 release 历史
install	安装一个 chart
list	列出 release
package	将 chart 目录打包到 chart 存档文件中
pull	从远程仓库中下载 chart 并解压到本地 # helm pull stable/mysql -- untar
repo	添加，列出，移除，更新和索引 chart 仓库。可用子命令：add、index、 list、remove、update
rollback	从之前版本回滚
search	根据关键字搜索 chart。可用子命令：hub、repo
show	查看 chart 详细信息。可用子命令：all、chart、readme、values
status	显示已命名版本的状态
template	本地呈现模板
uninstall	卸载一个 release
upgrade	更新一个 release
version	查看 helm 客户端版本

2.3.1 查询官方应用中心

[root@k8s-master helm]# helm search  hub nginx      #在官方仓库中搜索
[root@k8s-master helm]# helm  search  repo  nginx   #在本地仓库中搜索

2.3.2 管理第三方repo源

阿里云仓库：https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts
bitnami仓库： https://charts.bitnami.com/bitnami
微软仓库：Index of /kubernetes/charts/
官方仓库： https://hub.kubeapps.com/charts/incubator

#添加阿里云仓库,
[root@k8s-master helm]# helm repo  add aliyun https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts
"aliyun" has been added to your repositories

#添加bitnami仓库
[root@k8s-master helm]# helm repo add bitnami https://charts.bitnami.com/bitnami
"bitnami" has been added to your repositories

#查看仓库信息
[root@k8s-master helm]# helm repo list
NAME    URL
aliyun  https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts
bitnami https://charts.bitnami.com/bitnami

#查看仓库存储helm清单
[root@k8s-master helm]# helm search repo  aliyun

aliyun/aerospike                0.1.7           v3.14.1.2       A Helm chart for Aerospike in Kubernetes 

#删除第三方存储库
[root@k8s-master helm]# helm repo list
NAME    URL
aliyun  https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts
bitnami https://charts.bitnami.com/bitnami

[root@k8s-master helm]# helm repo remove aliyun
"aliyun" has been removed from your repositories
[root@k8s-master helm]# helm repo list
NAME    URL
bitnami https://charts.bitnami.com/bitnami

2.3.3 helm的使用方法

五构建helm仓库

5.1 在harbor仓库中构建一个公开的项目

5.2 安装helm push插件

官方网址：https://github.com/chartmuseum/helm-push

5.2.1 在线安装

如果网络没问题情况下直接安装即可

[root@k8s-master helm]# dnf install git -y
[root@k8s-master helm]# helm plugin install https://github.com/chartmuseum/helm-push

5.2.2 离线安装

#创建helm plugin的存放目录
[root@k8s-master helm]# mkdir  ~/.local/share/helm/plugins/helm-push -p

#解压push插件包到指定目录
[root@k8s-master helm]# tar zxf helm-push_0.10.4_linux_amd64.tar.gz -C ~/.local/share/helm/plugins/helm-push
[root@k8s-master helm]# ls ~/.local/share/helm/plugins/helm-push
bin  LICENSE  plugin.yaml

#查看helm调用命令是否成功
[root@k8s-master helm]# helm cm-push --help
Helm plugin to push chart package to ChartMuseum

Examples:

  $ helm cm-push mychart-0.1.0.tgz chartmuseum       # push .tgz from "helm package"
  $ helm cm-push . chartmuseum                       # package and push chart directory
  $ helm cm-push . --version="1.2.3" chartmuseum     # override version in Chart.yaml
  $ helm cm-push . https://my.chart.repo.com         # push directly to chart repo URL

5.3 上传项目到仓库

5.3.1 添加仓库

[root@K8s-master helm]# helm repo  add timinglee https://reg.harbor.org/chartrepo/zhang1
#添加仓库时报错，因为我们用的是加密访问
Error: looks like "https://reg.harbor.org/chartrepo/zhang1" is not a valid chart repository or cannot be reached: Get "https://reg.harbor.org/chartrepo/zhang/index.yaml": tls: failed to verify certificate: x509: certificate signed by unknown authority

#为helm添加证书
[root@K8s-master helm]# cp /etc/docker/certs.d/reg.harbor.org/ca.crt /etc/pki/ca-trust/source/anchors/

#更新本地ca认证库
[root@K8s-master helm]# update-ca-trust

#再次添加仓库
[root@K8s-master helm]# helm repo  add zhang https://reg.harbor.org/chartrepo/zhang1
"zhang" has been added to your repositories

5.3.2 上传本地项目

#命令执行格式
helm cm-push <项目名称> <仓库名称> -u admin -p redhat
[root@K8s-master helm]#  helm cm-push zhang-0.1.0.tgz zhang -u admin -p redhat
