/*Package chartutil contains tools for working with charts.
|
|
|
|
|
|
|
|
|
|
Charts are described in the protocol buffer definition (pkg/proto/hapi/charts).
|
|
|
|
|
This packe provides utilities for serializing and deserializing charts.
|
|
|
|
|
|
|
|
|
|
A chart can be represented on the file system in one of two ways:
|
|
|
|
|
|
|
|
|
|
- As a directory that contains a Chart.yaml file and other chart things.
|
|
|
|
|
- As a tarred gzipped file containing a directory that then contains a
|
|
|
|
|
Chart.yaml file.
|
|
|
|
|
|
|
|
|
|
This package provides utilitites for working with those file formats.
|
|
|
|
|
|
|
|
|
|
The preferred way of loading a chart is using 'chartutil.Load`:
|
|
|
|
|
|
|
|
|
|
chart, err := chartutil.Load(filename)
|
|
|
|
|
|
|
|
|
|
This will attempt to discover whether the file at 'filename' is a directory or
|
|
|
|
|
a chart archive. It will then load accordingly.
|
|
|
|
|
|
|
|
|
|
For accepting raw compressed tar file data from an io.Reader, the
|
|
|
|
|
'chartutil.LoadArchive()' will read in the data, uncompress it, and unpack it
|
|
|
|
|
into a Chart.
|
|
|
|
|
|
|
|
|
|
When creating charts in memory, use the 'k8s.io/helm/pkg/proto/happy/chart'
|
|
|
|
|
package directly.
