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。

  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

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

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’。

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

可选项

  1. --atomic if set, the installation process deletes the installation on failure. The --wait flag will be set automatically if --atomic is used
  2. --ca-file string verify certificates of HTTPS-enabled servers using this CA bundle
  3. --cert-file string identify HTTPS client using this SSL certificate file
  4. --create-namespace create the release namespace if not present
  5. --dependency-update update dependencies if they are missing before installing the chart
  6. --description string add a custom description
  7. --devel use development versions, too. Equivalent to version '>0.0.0-0'. If --version is set, this is ignored
  8. --disable-openapi-validation if set, the installation process will not validate rendered templates against the Kubernetes OpenAPI Schema
  9. --dry-run simulate an install
  10. -g, --generate-name generate the name (and omit the NAME parameter)
  11. -h, --help help for install
  12. --insecure-skip-tls-verify skip tls certificate checks for the chart download
  13. --key-file string identify HTTPS client using this SSL key file
  14. --keyring string location of public keys used for verification (default "~/.gnupg/pubring.gpg")
  15. --name-template string specify template used to name the release
  16. --no-hooks prevent hooks from running during install
  17. -o, --output format prints the output in the specified format. Allowed values: table, json, yaml (default table)
  18. --pass-credentials pass credentials to all domains
  19. --password string chart repository password where to locate the requested chart
  20. --post-renderer postrenderer the path to an executable to be used for post rendering. If it exists in $PATH, the binary will be used, otherwise it will try to look for the executable at the given path (default exec)
  21. --render-subchart-notes if set, render subchart notes along with the parent
  22. --replace re-use the given name, only if that name is a deleted release which remains in the history. This is unsafe in production
  23. --repo string chart repository url where to locate the requested chart
  24. --set stringArray set values on the command line (can specify multiple or separate values with commas: key1=val1,key2=val2)
  25. --set-file stringArray set values from respective files specified via the command line (can specify multiple or separate values with commas: key1=path1,key2=path2)
  26. --set-string stringArray set STRING values on the command line (can specify multiple or separate values with commas: key1=val1,key2=val2)
  27. --skip-crds if set, no CRDs will be installed. By default, CRDs are installed if not already present
  28. --timeout duration time to wait for any individual Kubernetes operation (like Jobs for hooks) (default 5m0s)
  29. --username string chart repository username where to locate the requested chart
  30. -f, --values strings specify values in a YAML file or a URL (can specify multiple)
  31. --verify verify the package before using it
  32. --version string specify a version constraint for the chart version to use. This constraint can be a specific tag (e.g. 1.1.1) or it may reference a valid range (e.g. ^2.0.0). If this is not specified, the latest version is used
  33. --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

从父命令继承的命令

  1. --debug enable verbose output
  2. --kube-apiserver string the address and the port for the Kubernetes API server
  3. --kube-as-group stringArray group to impersonate for the operation, this flag can be repeated to specify multiple groups.
  4. --kube-as-user string username to impersonate for the operation
  5. --kube-context string name of the kubeconfig context to use
  6. --kube-token string bearer token used for authentication
  7. --kubeconfig string path to the kubeconfig file
  8. -n, --namespace string namespace scope for this request
