Functions

func BuildPipelinesFallback 

func BuildPipelinesFallback() []string

Fallbacks: When a new method is added to an interface to provide to provide information that isn't available for older implementations, the older methods should return a fallback/default value by calling the appropriate function from below. Example: Exports() simply returns "assembler" for older image type implementations that didn't produce v1 manifests that have named pipelines.

func ExportsFallback 

func ExportsFallback() []string

func GetHostDistroName added in v0.33.0 

func GetHostDistroName() (string, error)

GetHostDistroName returns the name of the host distribution, such as "fedora-32" or "rhel-8.2". It does so by reading the /etc/os-release file.

func PayloadPackageSets 

func PayloadPackageSets() []string

func PayloadPipelinesFallback 

func PayloadPipelinesFallback() []string

func ReadOSReleaseFromTree added in v0.54.0 

func ReadOSReleaseFromTree(root string) (map[string]string, error)

ReadOSReleaseFromTree reads the os-release file from the given root directory.

According to os-release(5), the os-release file should be located in either /etc/os-release or /usr/lib/os-release, so both locations are tried, with the former taking precedence.

Types
