Functions

func BuildArgumentListFromMap added in v1.8.0

func BuildArgumentListFromMap(baseArguments map[string]string, overrideArguments map[string]string) []string

func CheckErr

func CheckErr(err error)

CheckErr prints a user friendly error to STDERR and exits with a non-zero exit code. Unrecognized errors will be printed with an "error: " prefix.

This method is generic to the command in use and may be used by non-Kubectl commands.

func Chroot added in v1.12.0

func Chroot(rootfs string) error

Chroot chroot()s to the new path. NB: All file paths after this call are effectively relative to `rootfs`

func CopyDir(src string, dst string) error

CopyDir copies the content of a folder

func FormatErrMsg added in v1.9.0

func FormatErrMsg(errs []error) string

func GetCgroupDriverDocker added in v1.11.0

func GetCgroupDriverDocker(execer utilsexec.Interface) (string, error)

GetCgroupDriverDocker runs 'docker info' to obtain the docker cgroup driver

func GetControlPlaneEndpoint added in v1.14.0

func GetControlPlaneEndpoint(controlPlaneEndpoint string, localEndpoint *kubeadmapi.APIEndpoint) (string, error)

GetControlPlaneEndpoint returns a properly formatted endpoint for the control plane built according following rules: - If the controlPlaneEndpoint is defined, use it. - if the controlPlaneEndpoint is defined but without a port number, use the controlPlaneEndpoint + localEndpoint.BindPort is used. - Otherwise, in case the controlPlaneEndpoint is not defined, use the localEndpoint.AdvertiseAddress + the localEndpoint.BindPort.

func GroupVersionKindsFromBytes added in v1.12.0

func GroupVersionKindsFromBytes(b []byte) ([]schema.GroupVersionKind, error)

GroupVersionKindsFromBytes parses the bytes and returns a gvk slice

func GroupVersionKindsHasClusterConfiguration added in v1.12.0

func GroupVersionKindsHasClusterConfiguration(gvks ...schema.GroupVersionKind) bool

GroupVersionKindsHasClusterConfiguration returns whether the following gvk slice contains a ClusterConfiguration object

func GroupVersionKindsHasInitConfiguration added in v1.12.0

func GroupVersionKindsHasInitConfiguration(gvks ...schema.GroupVersionKind) bool

GroupVersionKindsHasInitConfiguration returns whether the following gvk slice contains a InitConfiguration object

func GroupVersionKindsHasJoinConfiguration added in v1.12.0

func GroupVersionKindsHasJoinConfiguration(gvks ...schema.GroupVersionKind) bool

GroupVersionKindsHasJoinConfiguration returns whether the following gvk slice contains a JoinConfiguration object

func GroupVersionKindsHasKind added in v1.12.0

func GroupVersionKindsHasKind(gvks []schema.GroupVersionKind, kind string) bool

GroupVersionKindsHasKind returns whether the following gvk slice contains the kind given as a parameter

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.

func MarshalToYamlForCodecs added in v1.9.0

func MarshalToYamlForCodecs(obj runtime.Object, gv schema.GroupVersion, codecs serializer.CodecFactory) ([]byte, error)

MarshalToYamlForCodecs marshals an object into yaml using the specified codec TODO: Is specifying the gv really needed here? TODO: Can we support json out of the box easily here?

func ParseArgumentListToMap added in v1.8.0

func ParseArgumentListToMap(arguments []string) map[string]string

ParseArgumentListToMap parses a CLI argument list in the form "--foo=bar" to a string-string map
