This command creates a chart directory along with the common files and
|
|
directories used in a chart.
|
|
|
|
For example, 'helm create foo' will create a directory structure that looks
|
|
something like this:
|
|
|
|
foo/
|
|
|
|
|
|- .helmignore # Contains patterns to ignore when packaging Helm charts.
|
|
|
|
|
|- Chart.yaml # Information about your chart
|
|
|
|
|
|- values.yaml # The default values for your templates
|
|
|
|
|
|- charts/ # Charts that this chart depends on
|
|
|
|
|
|- templates/ # The template files
|
|
|
|
'helm create' takes a path for an argument. If directories in the given path
|
|
do not exist, Helm will attempt to create them as it goes. If the given
|
|
destination exists and there are files in that directory, conflicting files
|
|
will be overwritten, but other files will be left alone.
