)func BuildArgumentListFromMap(baseArguments map[string]string, overrideArguments map[string]string) []string
BuildArgumentListFromMap takes two string-string maps, one with the base arguments and one with optional override arguments. In the return list override arguments will precede base arguments
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.
Chroot chroot()s to the new path. NB: All file paths after this call are effectively relative to `rootfs`
CopyDir copies the content of a folder
FormatErrMsg returns a human-readable string describing the slice of errors passed to the function
GetCgroupDriverDocker runs 'docker info -f "{{.CgroupDriver}}"' to obtain the docker cgroup driver
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.
GetHostname returns OS's hostname if 'hostnameOverride' is empty; otherwise, return 'hostnameOverride' NOTE: This function copied from pkg/util/node package to avoid external kubeadm dependency
func GetLocalAPIEndpoint(localEndpoint *kubeadmapi.APIEndpoint) (string, error)
GetLocalAPIEndpoint parses an APIEndpoint and returns it as a string, or returns and error in case it cannot be parsed.
GetProxyEnvVars builds a list of environment variables in order to use the right proxy
func GroupVersionKindsFromBytes(b []byte) ([]schema.GroupVersionKind, error)
GroupVersionKindsFromBytes parses the bytes and returns a gvk slice
func GroupVersionKindsHasClusterConfiguration(gvks ...schema.GroupVersionKind) bool
GroupVersionKindsHasClusterConfiguration returns whether the following gvk slice contains a ClusterConfiguration object
func GroupVersionKindsHasInitConfiguration(gvks ...schema.GroupVersionKind) bool
GroupVersionKindsHasInitConfiguration returns whether the following gvk slice contains a InitConfiguration object
func GroupVersionKindsHasJoinConfiguration(gvks ...schema.GroupVersionKind) bool
GroupVersionKindsHasJoinConfiguration returns whether the following gvk slice contains a JoinConfiguration object
func GroupVersionKindsHasKind(gvks []schema.GroupVersionKind, kind string) bool
GroupVersionKindsHasKind returns whether the following gvk slice contains the kind given as a parameter
KubernetesIsCIVersion checks if user requested CI version
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, ...)
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.
MarshalToYaml marshals an object into yaml.
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?
ParseArgumentListToMap parses a CLI argument list in the form "--foo=bar" to a string-string map
ParseHostPort parses a network address of the form "host:port", "ipv4:port", "[ipv6]:port" into host and port; ":port" can be eventually omitted. If the string is not a valid representation of network address, ParseHostPort returns an error.
ParsePort parses a string representing a TCP port. If the string is not a valid representation of a TCP port, ParsePort returns an error.
ParseTemplate validates and parses passed as argument template
func ReplaceArgument(command []string, argMutateFunc func(map[string]string) map[string]string) []string
ReplaceArgument gets a command list; converts it to a map for easier modification, runs the provided function that returns a new modified map, and then converts the map back to a command string slice
func SplitYAMLDocuments(yamlBytes []byte) (kubeadmapi.DocumentMap, error)
SplitYAMLDocuments reads the YAML bytes per-document, unmarshals the TypeMeta information from each document and returns a map between the GroupVersionKind of the document and the document bytes
UnmarshalFromYaml unmarshals yaml into an object.
func UnmarshalFromYamlForCodecs(buffer []byte, gv schema.GroupVersion, codecs serializer.CodecFactory) (runtime.Object, error)
UnmarshalFromYamlForCodecs unmarshals yaml into an object using the specified codec TODO: Is specifying the gv really needed here? TODO: Can we support json out of the box easily here?
