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'。 示例中要是值太大,则您既不想用'--values'也不想用'--set',使用'--set-file'从文件中读取单个较大的值。

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

或者

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

或者

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

或者

$ helm install --set-file my_script=dothings.sh 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:

$ 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:

    $ helm install --set foo=bar --set foo=newbar  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。

注意: 在crds/目录中的CRD清单不能用 --dry-run 验证。查看 Helm's CRDs caveats 获取更多信息。

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。

有五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

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'。

helm install [NAME] [CHART] [flags]

可选项

      --atomic                       if set, the installation process deletes the installation on failure. The --wait flag will be set automatically if --atomic is used
      --ca-file string               verify certificates of HTTPS-enabled servers using this CA bundle
      --cert-file string             identify HTTPS client using this SSL certificate file

      --devel                        use development versions, too. Equivalent to version '>0.0.0-0'. If --version is set, this is ignored
      --disable-openapi-validation   if set, the installation process will not validate rendered templates against the Kubernetes OpenAPI Schema
      --dry-run                      simulate an install

      --key-file string              identify HTTPS client using this SSL key file
      --keyring string               location of public keys used for verification (default "~/.gnupg/pubring.gpg")

      --password string              chart repository password where to locate the requested chart

      --replace                      re-use the given name, only if that name is a deleted release which remains in the history. This is unsafe in production

      --wait                         if set, will wait until all Pods, PVCs, Services, and minimum number of Pods of a Deployment, StatefulSet, or ReplicaSet are in a ready state before marking the release as successful. It will wait for as long as --timeout
