Golang LoadChartfile Examples

Example #1

File: chartfile.go Project: runseb/helm

// Chartfile runs a set of linter rules related to Chart.yaml file
func Chartfile(linter *support.Linter) {
	chartFileName := "Chart.yaml"
	chartPath := filepath.Join(linter.ChartDir, chartFileName)

	linter.RunLinterRule(support.ErrorSev, chartFileName, validateChartYamlNotDirectory(chartPath))

	chartFile, err := chartutil.LoadChartfile(chartPath)
	validChartFile := linter.RunLinterRule(support.ErrorSev, chartFileName, validateChartYamlFormat(err))

	// Guard clause. Following linter rules require a parseable ChartFile
	if !validChartFile {
		return
	}

	linter.RunLinterRule(support.ErrorSev, chartFileName, validateChartName(chartFile))
	linter.RunLinterRule(support.ErrorSev, chartFileName, validateChartNameDirMatch(linter.ChartDir, chartFile))

	// Chart metadata
	linter.RunLinterRule(support.ErrorSev, chartFileName, validateChartVersion(chartFile))
	linter.RunLinterRule(support.ErrorSev, chartFileName, validateChartEngine(chartFile))
	linter.RunLinterRule(support.ErrorSev, chartFileName, validateChartMaintainer(chartFile))
	linter.RunLinterRule(support.ErrorSev, chartFileName, validateChartSources(chartFile))
}
