Helm命令参考

查询charts

helm search
helm search mysql

查询package详细信息

helm inspect stable/mariadb

部署package

helm install stable/mysql

部署之前可以自定义package的选项：

# 查询支持的选项
helm inspect values stable/mysql

# 自定义password
echo "mysqlRootPassword: passwd" > config.yaml
helm install -f config.yaml stable/mysql

另外，还可以通过打包文件（.tgz）或者本地package路径（如path/foo）来部署应用。
