To begin working with Helm, run the 'helm init' command:
|
||||
|
||||
$ helm init
|
||||
|
||||
This will set up any necessary local configuration.
|
||||
|
||||
Common actions from this point include:
|
||||
|
||||
- helm search: search for charts
|
||||
- helm fetch: download a chart to your local directory to view
|
||||
- helm install: upload the chart to Kubernetes
|
||||
- helm list: list releases of charts
|
||||
|
||||
Environment:
|
||||
$HELM_HOME set an alternative location for Helm files. By default, these are stored in ~/.helm
|
||||
$HELM_NO_PLUGINS disable plugins. Set HELM_NO_PLUGINS=1 to disable plugins.
|
||||
$KUBECONFIG set an alternative Kubernetes configuration file (default "~/.kube/config")
