helm安装文档： https://helm.sh/docs/intro/install/
创建一个chart helm create helm-test

values.yaml
with:
helm install test --dry-run .
include：引入的函数或者模板，_helpers.tpl
define：定义一个模板， trunc：只取前多少位字符，负号代表从后往前取 trimSuffix： 字符串末尾去掉指定的字符，Prefix
$name := xxx 定义一个变量 default： 定义的变量的默认值 contains： 判断字符串是否包含某个字符串 replace： 替换字符串
常用函数：http://masterminds.github.io/sprig/strings.html
helm install helm-test2 --set fullnameOverride=aaaaaaa --dry-run . --set 修改values里面的值
helm install rabbitmq-cluster --namespace public-service --set replicaCount=2 . 删除helm uninstall rabbitmq-cluster -n public-service # helm v3 --keep-history helm delete/del NAME --purge 升级helm upgrade rabbitmq-cluster -n public-service .
