Helm 升级

helm upgrade

升级版本

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’。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：

  1.     $ 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：

  1.     $ helm upgrade --set foo=bar --set foo=newbar redis ./redis
  1. helm upgrade [RELEASE] [CHART] [flags]
