func (RealHelmChartProcessor) DownloadHelmChart ¶
func (g RealHelmChartProcessor) DownloadHelmChart(cmdRunner interfaces.CmdRunner, globber interfaces.Globber, cacheDir, repoUrl, chartName, targetRevision string, repoCredentials []models.RepoCredentials) error
DownloadHelmChart fetches a specified version of a Helm chart from a given repository URL and stores it in a cache directory. The function leverages the provided CmdRunner to execute the helm pull command and Globber to deal with possible non-standard chart naming. If the chart is already present in the cache, the function just logs the information and doesn't download it again. The function is designed to handle potential errors during directory creation, globbing, and Helm chart downloading. Any critical error during these operations terminates the program.
func (RealHelmChartProcessor) ExtractHelmChart ¶
func (g RealHelmChartProcessor) ExtractHelmChart(cmdRunner interfaces.CmdRunner, globber interfaces.Globber, chartName, chartVersion, chartLocation, tmpDir, targetType string) error
ExtractHelmChart extracts a specific version of a Helm chart from a cache directory and stores it in a temporary directory. The function uses the provided CmdRunner to execute the tar command and Globber to match the chart file in the cache. If multiple files matching the pattern are found, an error is returned. The function logs any output (standard or error) from the tar command. Any critical error during these operations, like directory creation or extraction failure, terminates the program.
func (RealHelmChartProcessor) GenerateValuesFile ¶
func (g RealHelmChartProcessor) GenerateValuesFile(chartName, tmpDir, targetType, values string, valuesObject map[string]interface{}) error
GenerateValuesFile creates a Helm values file for a given chart in a specified directory. It takes a chart name, a temporary directory for storing the file, the target type categorizing the application, and the content of the values file in string format. The function first attempts to create the file. If an error occurs, it terminates the program. Next, it writes the values string to the file. If an error occurs during this process, the program is also terminated.
func (RealHelmChartProcessor) RenderAppSource ¶
func (g RealHelmChartProcessor) RenderAppSource(cmdRunner interfaces.CmdRunner, releaseName, chartName, chartVersion, tmpDir, targetType string) error
RenderAppSource uses the Helm CLI to render the templates of a given chart. It takes a cmdRunner to run the Helm command, a release name for the Helm release, the chart name and version, a temporary directory for storing intermediate files, and the target type which categorizes the application. The function constructs the Helm command with the provided arguments, runs it, and checks for any errors. If there are any errors, it returns them. Otherwise, it returns nil.
