func KubernetesIsCIVersion added in v1.8.0

func KubernetesIsCIVersion(version string) bool

KubernetesIsCIVersion checks if user requested CI version

func KubernetesReleaseVersion added in v1.6.0

func KubernetesReleaseVersion(version string) (string, error)

KubernetesReleaseVersion is helper function that can fetch available version information from release servers based on label names, like "stable" or "latest".

If argument is already semantic version string, it will return same string.

In case of labels, it tries to fetch from release servers and then return actual semantic version.

Available names on release servers:

stable      (latest stable release)
stable-1    (latest stable release in 1.x)
stable-1.0  (and similarly 1.1, 1.2, 1.3, ...)
latest      (latest release, including alpha/beta)
latest-1    (latest release in 1.x, including alpha/beta)
latest-1.0  (and similarly 1.1, 1.2, 1.3, ...)

func KubernetesVersionToImageTag added in v1.8.0

func KubernetesVersionToImageTag(version string) string

KubernetesVersionToImageTag is helper function that replaces all non-allowed symbols in tag strings with underscores. Image tag can only contain lowercase and uppercase letters, digits, underscores, periods and dashes. Current usage is for CI images where all of symbols except '+' are valid, but function is for generic usage where input can't be always pre-validated.

func MarshalToYaml added in v1.9.0

func MarshalToYaml(obj runtime.Object, gv schema.GroupVersion) ([]byte, error)

MarshalToYaml marshals an object into yaml.
