Functions

func BuildBundleImage 

func BuildBundleImage(imageTag, imageBuilder string) (*exec.Cmd, error)

Create build command to build bundle manifests image

func BuildFunc 

func BuildFunc(directory, outputDir, imageTag, imageBuilder, packageName, channels, channelDefault string,
	overwrite bool) error

BuildFunc is used to build bundle container image from a list of manifests that exist in local directory and it also generates Dockerfile annotations.yaml which contains media type, package name and channels information if the file doesn't exist locally. Inputs: @directory: The local directory where bundle manifests and metadata are located @imageTag: The image tag that is applied to the bundle image @imageBuilder: The image builder tool that is used to build container image (docker, buildah or podman) @packageName: The name of the package that bundle image belongs to @channels: The list of channels that bundle image belongs to @channelDefault: The default channel for the bundle image @overwrite: Boolean flag to enable overwriting annotations.yaml locally if existed

func CopyYamlOutput 

func CopyYamlOutput(annotationsContent []byte, manifestDir, outputDir, workingDir string, overwrite bool) (resultManifests, resultMetadata string, err error)

CopyYamlOutput takes the generated annotations yaml and writes it to disk. If an outputDir is specified, it will copy the input manifests It returns two strings. resultMetadata is the path to the output metadata/ folder. resultManifests is the path to the output manifests/ folder -- if no copy occured, it just returns the input manifestDir

func ExecuteCommand 

func ExecuteCommand(cmd *exec.Cmd) error

func GenerateAnnotations 

func GenerateAnnotations(mediaType, manifests, metadata, packageName, channels, channelDefault string) ([]byte, error)

GenerateAnnotations builds annotations.yaml with mediatype, manifests & metadata directories in bundle image, package name, channels and default channels information.

func GenerateDockerfile 

func GenerateDockerfile(mediaType, manifests, metadata, copyManifestDir, copyMetadataDir, workingDir, packageName, channels, channelDefault string) ([]byte, error)

GenerateDockerfile builds Dockerfile with mediatype, manifests & metadata directories in bundle image, package name, channels and default channels information in LABEL section.

func GenerateFunc 

func GenerateFunc(directory, outputDir, packageName, channels, channelDefault string, overwrite bool) error

GenerateFunc builds annotations.yaml with mediatype, manifests & metadata directories in bundle image, package name, channels and default channels information and then writes the file to `/metadata` directory. Inputs: @directory: The local directory where bundle manifests and metadata are located @outputDir: Optional generated path where the /manifests and /metadata directories are copied as they would appear on the bundle image @packageName: The name of the package that bundle image belongs to @channels: The list of channels that bundle image belongs to @channelDefault: The default channel for the bundle image @overwrite: Boolean flag to enable overwriting annotations.yaml locally if existed

func GetMediaType 

func GetMediaType(directory string) (string, error)

GetMediaType determines mediatype from files (yaml) in given directory Currently able to detect helm chart, registry+v1 (CSV) and plain k8s resources such as CRD.

func IsChartDir 

func IsChartDir(dirName string) (bool, error)

IsChartDir validates a chart directory.

Checks for a valid Chart.yaml.

func NewBundleDirInterperter 

func NewBundleDirInterperter(bundleDir string) (*bundleDirInterpreter, error)

func ValidateAnnotations 

func ValidateAnnotations(existing, expected []byte) error

ValidateAnnotations validates existing annotations.yaml against generated annotations.yaml to ensure existing annotations.yaml contains expected values.

func WriteFile 

func WriteFile(fileName, directory string, content []byte) error

Write `fileName` file with `content` into a `directory` Note: Will overwrite the existing `fileName` file if it exists
