简介
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’)，chart目录路径，打包的chart或者完整URL。
对于chart引用，除非使用’–version’参数指定，否则会使用最新版本。
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’。当值本身对于命令行太长或者是动态生成的时候，可以使用 ‘–set-file’ 设置独立的值。
也可以在命令行使用’–set-json’参数设置json值(scalars/objects/arrays)。
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
