Helm 安装

helm install

安装chart

简介

该命令用于安装chart包。

安装参数必须是chart的引用，一个打包后的chart路径，未打包的chart目录或者是一个URL。

要重写chart中的值，使用’—values’参数传递一个文件或者使用’—set’参数在命令行传递配置，强制使用字符串要用’—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)。

  1. $ helm install -f myvalues.yaml myredis ./redis

或者

  1. $ helm install --set name=prod myredis ./redis

或者

  1. $ helm install --set-string long_int=1234567890 myredis ./redis

或者

  1. $ helm install --set-file my_script=dothings.sh myredis ./redis

或者

  1. $ helm install --set-json 'master.sidecars=[{"name":"sidecar","image":"myImage","imagePullPolicy":"Always",ports":[{"name":"portname","containerPort":1234}]}]' myredis ./redis

你可以多次指定’—values’/‘-f’参数。最右侧指定的文件优先级最高。比如，如果两个文件myvalues.yaml和override.yaml 都包含名为’Test’的可以，override.yaml中的值优先：

  1. $ helm install -f myvalues.yaml -f override.yaml  myredis ./redis

可以指定’—set’参数多次，最右边的参数优先级最高，比如，’bar’和’newbar’都设置了一个名为’foo’的可以，’newbar’的值优先：

  1.     $ helm install --set foo=bar --set foo=newbar  myredis ./redis

类似地,下面的示例中’foo’被设置成了’[“four”]‘:

  1.     $ helm install --set-json='foo=["one", "two", "three"]' --set-json='foo=["four"]' myredis ./redis

下面的示例中，’foo’被设置成了’{“key1”:”value1”,”key2”:”bar”}’：

  1.     $ helm install --set-json='foo={"key1":"value1","key2":"value2"}' --set-json='foo.key2="bar"' myredis ./redis

为了检测生成的清单，但并不安装到chart，可以将’—debug’和’—dry-run’组合使用。

如果设置了—verify，chart必须有出处文件，且出处文件必须传递所有的验证步骤。

有六种不同的方式来标识需要安装的chart：

  1. 通过chart引用： helm install mymaria example/mariadb
  2. 通过chart包： helm install mynginx ./nginx-1.2.3.tgz
  3. 通过未打包chart目录的路径： helm install mynginx ./nginx
  4. 通过URL绝对路径： helm install mynginx https://example.com/charts/nginx-1.2.3.tgz
  5. 通过chart引用和仓库url： helm install —repo https://example.com/charts/ mynginx nginx
  6. 通过OCI注册中心： helm install mynginx —version 1.2.3 oci://example.com/charts/nginx

CHART引用

chart引用是在chart仓库中引用chart的一种方便方式。

当你用仓库前缀(‘example/mariadb’)引用chart时，Helm会在本地配置查找名为 ‘example’ 的chart仓库， 然后会在仓库中查找名为’mariadb’的仓库，然后会安装这个chart最新的稳定版本，除非指定了’—devel’参数且包含了开发版本(alpha， beta，和候选版本)，或者使用’—version’参数提供一个版本号。

要查看仓库列表，使用’helm repo list’。要在仓库中搜索chart，使用’helm search’。

  1. helm install [NAME] [CHART] [flags]
