helm的三个核心概念:
helm安装有四种方式:
helm install stable/mysql
helm install mysql-2.3.tgz
helm install mysql/
helm install http://127.0.0.1:8879/charts/mysql
首先查找包,如想要安装mysql,helm search mysql
,mysql是个关键字,如果一个chart中的chart.yaml文件内定义了这个关键字,则可以被搜索到.
$ helm search mysql

查看安装包的内容,helm inspect -h, helm inspect values 只查看暴露的自定义参数, 或者直接helm fetch下载此安装包至当前目录.
$ helm inspect values stable/mysql

输出K8s的资源文件,参数与install一样.使用--dry-run --debug
来模拟安装过程并打印配置信息.
cat << EOF > config.yaml
mariadbUser: user0
mariadbDatabase: user0db
EOF
helm install stable/mysql -f configure.yaml --set service.nodePort=31313
# 只查看安装过程中的文件,不进行实际安装.
helm install stable/mysql -f configure.yaml --set service.nodePort=31313 --debug --dry-run
# 输出对应k8s的yaml文件
helm template stable/mysql -f configure.yaml --set service.nodePort=31313
$ helm ls
