Overview

Package clientcmd provides one stop shopping for building a working client from a fixed config, from a .kubeconfig file, from command line flags, or from any merged combination.

Sample usage from merged .kubeconfig files (local directory, home directory) 

loadingRules := clientcmd.NewDefaultClientConfigLoadingRules()
// if you want to change the loading rules (which files in which order), you can do so here

configOverrides := &clientcmd.ConfigOverrides{}
// if you want to change override values or bind them to flags, there are methods to help you

kubeConfig := clientcmd.NewNonInteractiveDeferredLoadingClientConfig(loadingRules, configOverrides)
config, err := kubeConfig.ClientConfig()
if err != nil {
	// Do something
}
client, err := metav1.New(config)
// ...

BindAuthInfoFlags is a convenience method to bind the specified flags to their associated variables

func BindClusterFlags 

func BindClusterFlags(clusterInfo *clientcmdapi.Cluster, flags *pflag.FlagSet, flagNames ClusterOverrideFlags)

BindClusterFlags is a convenience method to bind the specified flags to their associated variables

BindOverrideFlags is a convenience method to bind the specified flags to their associated variables

func BuildConfigFromFlags 

func BuildConfigFromFlags(masterUrl, kubeconfigPath string) (*restclient.Config, error)

BuildConfigFromFlags is a helper function that builds configs from a master url or a kubeconfig filepath. These are passed in as command line flags for cluster components. Warnings should reflect this usage. If neither masterUrl or kubeconfigPath are passed in we fallback to inClusterConfig. If inClusterConfig fails, we fallback to the default config.

func BuildConfigFromKubeconfigGetter 

func BuildConfigFromKubeconfigGetter(masterUrl string, kubeconfigGetter KubeconfigGetter) (*restclient.Config, error)

BuildConfigFromKubeconfigGetter is a helper function that builds configs from a master url and a kubeconfigGetter.

func ConfirmUsable 

func ConfirmUsable(config clientcmdapi.Config, passedContextName string) error

ConfirmUsable looks a particular context and determines if that particular part of the config is useable. There might still be errors in the config, but no errors in the sections requested or referenced. It does not return early so that it can find as many errors as possible.

func GetAuthInfoFileReferences 

func GetAuthInfoFileReferences(authInfo *clientcmdapi.AuthInfo) []*string

func GetClusterFileReferences 

func GetClusterFileReferences(cluster *clientcmdapi.Cluster) []*string

func GetConfigFileReferences 

func GetConfigFileReferences(config *clientcmdapi.Config) []*string

func GetConfigFromFileOrDie 

func GetConfigFromFileOrDie(filename string) *clientcmdapi.Config

GetConfigFromFileOrDie tries to read a kubeconfig file and if it can't, it calls exit. One exception, missing files result in empty configs, not an exit

func IsConfigurationInvalid 

func IsConfigurationInvalid(err error) bool

IsConfigurationInvalid returns true if the provided error indicates the configuration is invalid.

func IsContextNotFound 

func IsContextNotFound(err error) bool

IsContextNotFound returns a boolean indicating whether the error is known to report that a context was not found

func IsEmptyConfig 

func IsEmptyConfig(err error) bool

func LoadFromFile 

func LoadFromFile(filename string) (*clientcmdapi.Config, error)

LoadFromFile takes a filename and deserializes the contents into Config object

func MakeRelative 

func MakeRelative(path, base string) (string, error)

func ModifyConfig 

func ModifyConfig(configAccess ConfigAccess, newConfig clientcmdapi.Config, relativizePaths bool) error

ModifyConfig takes a Config object, iterates through Clusters, AuthInfos, and Contexts, uses the LocationOfOrigin if specified or uses the default destination file to write the results into. This results in multiple file reads, but it's very easy to follow. Preferences and CurrentContext should always be set in the default destination file. Since we can't distinguish between empty and missing values (no nil strings), we're forced have separate handling for them. In the kubeconfig cases, newConfig should have at most one difference, that means that this code will only write into a single file. If you want to relativizePaths, you must provide a fully qualified path in any modified element.

func ParseTimeout 

func ParseTimeout(duration string) (time.Duration, error)

ParseTimeout returns a parsed duration from a string A duration string value must be a positive integer, optionally followed by a corresponding time unit (s|m|h).

func PersisterForUser 

func PersisterForUser(configAccess ConfigAccess, user string) restclient.AuthProviderConfigPersister

func RESTConfigFromKubeConfig 

func RESTConfigFromKubeConfig(configBytes []byte) (*restclient.Config, error)

func RelativizeAuthInfoLocalPaths 

func RelativizeAuthInfoLocalPaths(authInfo *clientcmdapi.AuthInfo) error

RelativizeAuthInfoLocalPaths first absolutizes the paths by calling ResolveLocalPaths. This assumes that any NEW path is already absolute, but any existing path will be resolved relative to LocationOfOrigin

func RelativizeClusterLocalPaths 

func RelativizeClusterLocalPaths(cluster *clientcmdapi.Cluster) error

RelativizeClusterLocalPaths first absolutizes the paths by calling ResolveLocalPaths. This assumes that any NEW path is already absolute, but any existing path will be resolved relative to LocationOfOrigin

func ResolveConfigPaths 

func ResolveConfigPaths(config *clientcmdapi.Config, base string) error

func ResolveLocalPaths 

func ResolveLocalPaths(config *clientcmdapi.Config) error

ResolveLocalPaths resolves all relative paths in the config object with respect to the stanza's LocationOfOrigin this cannot be done directly inside of LoadFromFile because doing so there would make it impossible to load a file without modification of its contents.

Load starts by running the MigrationRules and then takes the loading rules and returns a Config object based on following rules. 

if the ExplicitPath, return the unmerged explicit file
Otherwise, return a merged config based on the Precedence slice

A missing ExplicitPath file produces an error. Empty filenames or other missing files are ignored. Read errors or files with non-deserializable content produce errors. The first file to set a particular map key wins and map key's value is never changed. BUT, if you set a struct value that is NOT contained inside of map, the value WILL be changed. This results in some odd looking logic to merge in one direction, merge in the other, and then merge the two. It also means that if two files specify a "red-user", only values from the first file's red-user are used. Even non-conflicting entries from the second file's "red-user" are discarded. Relative paths inside of the .kubeconfig files are resolved against the .kubeconfig file's parent folder and only absolute file paths are returned.

func (*ClientConfigLoadingRules) Migrate
