通过打包的方式把deployment service ingress等打包在一块一键式的部署服务类似yum安装
官方提供的一个类似与安装仓库额功能可以实现一键化部署应用 helm的概念
三个部分组成
1、chartL helm的软件包部署包service ingress定义好的yaml资源类似于yum的rpm包
2、Release 可以理解为版本也可以理解为在安装过程中给这个部署的应用起一个名字
3、Repository 仓库提供一个服务器这个服务器中包含chartL的资源yaml的资源保存的地址 版本
helm3 命令行
helm3 纯命令行方式
把源码包拖到helm
helm-v3.12.0-linux-amd64.tar.gz
解压
tar -xf helm-v3.12.0-linux-amd64.tar.gz
进入linux-amd64/
cd linux-amd64/把helm拖到usr/local/bin下
mv helm /usr/local/bin/helm添加自动补全
vim /etc/profilesource (helm completion bash)
立刻生效
source /etc/profile搜索资源helm search repo aliyun | grep nginx查看chart的详细信息
helm show chart bitnami/nginx一般
helm show all bitnami/nginx所有安装
helm install my-nginx bitnami/nginx
helm install 安装
my-nginx 安装的名称或者版本
bitnami/nginx bitnami仓库名nginx就是chart一系列yaml资源的集合删除
helm uninstall my-nginxhelm install bitnami/nginx --generate-name
--generate-name 随机指定Release名称helm ls 查看所有安装Release
helm自定义模版
根据自己的需求自定义chart然后部署到集群当中
拉取包mysql
helm pull stable/mysql解压
tar -xf mysql-1.6.9.tgz创建nginx
helm create nginx查看创建的nginx的目录

└── values.yamlcharts 用于存储依赖如果这个chart依赖于其他的chart依赖文件保存在这个目录
Chart.yaml helm chart的元数据文件包含了这个chart的名称版本维护者信息等等
Template 包含清单模版目录
deployment.yaml 部署应用的模版文件
helpers.tpl 帮助文档告诉用户如何来定义模版的值
hpa.yaml 定义了应用程序副本数的扩缩容行为
ingress.yaml 定义了外部流量如何转发到应用程序
NOTES.txt 注意事项
serviceaccount.yaml 应用程序的服务账号
service.yaml 集群内部的访问
tests test-connection.yaml 测试的目录和文件部署完chart之后用来测试的文件
values.yaml 核心文件自定义的值都是通过values.yaml把我们数据覆盖到安装的chart修改values.yaml# Default values for nginx.

[rootmaster01 linux-amd64]# helm lint nginxLinting nginx

helm package nginx
Successfully packaged chart and saved it to: /opt/helm/linux-amd64/nginx-0.1.0.tgz部署
helm install nginx-11 ./nginx --dry-run --debug
helm install 安装chart
nginx-11 Release版本号
./nginx 当前目录下的nginx的chart
--dry-run --debug 这个chart不会被部署到集群当中参数验证测试chart的配置是否正确安装
方法一
helm install nginx-11 ./nginx -n default
方法二
helm install nginx-11 /opt/helm/linux-amd64/nginx-0.1.0.tgz -n default
删除
helm uninstall nginx-11
修改chart之后重新部署
