1. helm upgrade

升级版本

该命令将发布升级到新版的 chart。

升级参数必须是发布和 chart。chart 参数可以是：

• chart引用('example/mariadb'),对于chart引用，除非使用'--version'参数指定，否则会使用最新版本。
• chart目录路径
• 打包的chart或者完整URL。

要在 chart 中重写 value，需要使用 --values 参数并传一个文件或者从命令行使用 --set 参数传个配置， 要强制字符串值，使用--set-string。在值很大而不想使用 --values 和 --set 的场景中，使用 --set-file 从文件中读取单个的大值。

可以多次指定 --values/-f 参数，最后（最右边）指定的文件优先级最高。比如如果 myvalues.yaml 和 override.yaml 同时包含了名为 Test 的key，override.yaml 中的设置会优先使用：

$ helm upgrade -f myvalues.yaml -f override.yaml redis ./redis

可以多次指定 --set 参数，最后（最右边）指定的优先级最高。比如 bar 和 newbar 都设置了一个名为 foo 的可以， newbar的值会优先使用：

$ helm upgrade --set foo=bar --set foo=newbar redis ./redis

helm upgrade [RELEASE] [CHART] [flags]
