Helm Dependency

helm dependency

manage a chart’s dependencies

Synopsis

Manage the dependencies of a chart.

Helm charts store their dependencies in ‘charts/‘. For chart developers, it is often easier to manage dependencies in ‘Chart.yaml’ which declares all dependencies.

The dependency commands operate on that file, making it easy to synchronize between the desired dependencies and the actual dependencies stored in the ‘charts/‘ directory.

For example, this Chart.yaml declares two dependencies:

  1. # Chart.yaml
  2. dependencies:
  3. - name: nginx
  4.   version: "1.2.3"
  5.   repository: "https://example.com/charts"
  6. - name: memcached
  7.   version: "3.2.1"
  8.   repository: "https://another.example.com/charts"

The ‘name’ should be the name of a chart, where that name must match the name in that chart’s ‘Chart.yaml’ file.

The ‘version’ field should contain a semantic version or version range.

The ‘repository’ URL should point to a Chart Repository. Helm expects that by appending ‘/index.yaml’ to the URL, it should be able to retrieve the chart repository’s index. Note: ‘repository’ can be an alias. The alias must start with ‘alias:’ or ‘@’.

Starting from 2.2.0, repository can be defined as the path to the directory of the dependency charts stored locally. The path should start with a prefix of “file://“. For example,

  1. # Chart.yaml
  2. dependencies:
  3. - name: nginx
  4.   version: "1.2.3"
  5.   repository: "file://../dependency_chart/nginx"

If the dependency chart is retrieved locally, it is not required to have the repository added to helm by “helm add repo”. Version matching is also supported for this case.

Options

  1.   -h, --help   help for dependency

Options inherited from parent commands

  1.       --burst-limit int                 client-side default throttling limit (default 100)
  2.       --debug                           enable verbose output
  3.       --kube-apiserver string           the address and the port for the Kubernetes API server
  4.       --kube-as-group stringArray       group to impersonate for the operation, this flag can be repeated to specify multiple groups.
  5.       --kube-as-user string             username to impersonate for the operation
  6.       --kube-ca-file string             the certificate authority file for the Kubernetes API server connection

  8.       --kube-insecure-skip-tls-verify   if true, the Kubernetes API server's certificate will not be checked for validity. This will make your HTTPS connections insecure
  9.       --kube-tls-server-name string     server name to use for Kubernetes API server certificate validation. If it is not provided, the hostname used to contact the server is used
  10.       --kube-token string               bearer token used for authentication
  11.       --kubeconfig string               path to the kubeconfig file
  12.   -n, --namespace string                namespace scope for this request
  13.       --qps float32                     queries per second used when communicating with the Kubernetes API, not including bursting
  14.       --registry-config string          path to the registry config file (default "~/.config/helm/registry/config.json")
  15.       --repository-cache string         path to the directory containing cached repository indexes (default "~/.cache/helm/repository")
  16.       --repository-config string        path to the file containing repository names and URLs (default "~/.config/helm/repositories.yaml")
