The Helm package manager for Kubernetes.


The Kubernetes package manager

Common actions for Helm:

  • helm search: search for charts
  • helm pull: download a chart to your local directory to view
  • helm install: upload the chart to Kubernetes
  • helm list: list releases of charts

Environment variables:

$HELM_CACHE_HOMEset an alternative location for storing cached files.
$HELM_CONFIG_HOMEset an alternative location for storing Helm configuration.
$HELM_DATA_HOMEset an alternative location for storing Helm data.
$HELM_DEBUGindicate whether or not Helm is running in Debug mode
$HELM_DRIVERset the backend storage driver. Values are: configmap, secret, memory, sql.
$HELM_DRIVER_SQL_CONNECTION_STRINGset the connection string the SQL storage driver should use.
$HELM_MAX_HISTORYset the maximum number of helm release history.
$HELM_NAMESPACEset the namespace used for the helm operations.
$HELM_NO_PLUGINSdisable plugins. Set HELM_NO_PLUGINS=1 to disable plugins.
$HELM_PLUGINSset the path to the plugins directory
$HELM_REGISTRY_CONFIGset the path to the registry config file.
$HELM_REPOSITORY_CACHEset the path to the repository cache directory
$HELM_REPOSITORY_CONFIGset the path to the repositories file.
$KUBECONFIGset an alternative Kubernetes configuration file (default "~/.kube/config")
$HELM_KUBEAPISERVERset the Kubernetes API Server Endpoint for authentication
$HELM_KUBECAFILEset the Kubernetes certificate authority file.
$HELM_KUBEASGROUPSset the Groups to use for impersonation using a comma-separated list.
$HELM_KUBEASUSERset the Username to impersonate for the operation.
$HELM_KUBECONTEXTset the name of the kubeconfig context.
$HELM_KUBETOKENset the Bearer KubeToken used for authentication.
$HELM_KUBEINSECURE_SKIP_TLS_VERIFYindicate if the Kubernetes API server's certificate validation should be skipped (insecure)
$HELM_KUBETLS_SERVER_NAMEset the server name used to validate the Kubernetes API server certificate
$HELM_BURST_LIMITset the default burst limit in the case the server contains many CRDs (default 100, -1 to disable)
$HELM_QPSset the Queries Per Second in cases where a high number of calls exceed the option for higher burst values

Helm stores cache, configuration, and data based on the following configuration order:

  • If a HELM_*_HOME environment variable is set, it will be used
  • Otherwise, on systems supporting the XDG base directory specification, the XDG variables will be used
  • When no other location is set a default location will be used based on the operating system

By default, the default directories depend on the Operating System. The defaults are listed below:

Operating SystemCache PathConfiguration PathData Path


      --burst-limit int                 client-side default throttling limit (default 100)
      --debug                           enable verbose output
  -h, --help                            help for helm
      --kube-apiserver string           the address and the port for the Kubernetes API server
      --kube-as-group stringArray       group to impersonate for the operation, this flag can be repeated to specify multiple groups.
      --kube-as-user string             username to impersonate for the operation
      --kube-ca-file string             the certificate authority file for the Kubernetes API server connection
      --kube-context string             name of the kubeconfig context to use
      --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
      --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
      --kube-token string               bearer token used for authentication
      --kubeconfig string               path to the kubeconfig file
  -n, --namespace string                namespace scope for this request
      --qps float32                     queries per second used when communicating with the Kubernetes API, not including bursting
      --registry-config string          path to the registry config file (default "~/.config/helm/registry/config.json")
      --repository-cache string         path to the file containing cached repository indexes (default "~/.cache/helm/repository")
      --repository-config string        path to the file containing repository names and URLs (default "~/.config/helm/repositories.yaml")
