This command packages a chart into a versioned chart archive file. If a path
|
|
is given, this will look at that path for a chart (which must contain a
|
|
Chart.yaml file) and then package that directory.
|
|
|
|
If no path is given, this will look in the present working directory for a
|
|
Chart.yaml file, and (if found) build the current directory into a chart.
|
|
|
|
Versioned chart archives are used by Helm package repositories.
