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 := unversioned.New(config)
// ...

func BuildConfigFromFlags added in v1.2.0

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 added in v1.3.0

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 added in v1.3.0

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 added in v1.2.0

func IsEmptyConfig(err error) bool

IsEmptyConfig returns true if the provided error indicates the provided configuration is empty.

func Load

func Load(data []byte) (*clientcmdapi.Config, error)

Load takes a byte slice and deserializes the contents into Config object. Encapsulates deserialization without assuming the source is a file.

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 added in v1.3.0

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 PersisterForUser added in v1.3.0

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

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 RelativizeConfigPaths

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

func RelativizePathWithNoBacksteps

func RelativizePathWithNoBacksteps(refs []*string, base string) error

RelativizePathWithNoBacksteps updates the given refs to be relative paths, relative to the given base directory as long as they do not require backsteps. Any path requiring a backstep is left as-is as long it is absolute. Any non-absolute path that can't be relativized produces an error

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.

func ResolvePaths

func ResolvePaths(refs []*string, base string) error

ResolvePaths updates the given refs to be absolute paths, relative to the given base directory

func Validate

func Validate(config clientcmdapi.Config) error

Validate checks for errors in the Config. It does not return early so that it can find as many errors as possible.

func Write

func Write(config clientcmdapi.Config) ([]byte, error)

Write serializes the config to yaml. Encapsulates serialization without assuming the destination is a file.

func WriteToFile

func WriteToFile(config clientcmdapi.Config, filename string) error

WriteToFile serializes the config to yaml and writes it out to a file. If not present, it creates the file with the mode 0600. If it is present it stomps the contents

	// If the source file is present, then it is copied to the destination file BEFORE any further loading happens.
	MigrationRules map[string]string

	// DoNotResolvePaths indicates whether or not to resolve paths with respect to the originating files.  This is phrased as a negative so
	// that a default object that doesn't set this will usually get the behavior it wants.
	DoNotResolvePaths bool
}

ClientConfigLoadingRules is an ExplicitPath and string slice of specific locations that are used for merging together a Config Callers can put the chain together however they want, but we'd recommend: EnvVarPathFiles if set (a list of files if set) OR the HomeDirectoryPath ExplicitPath is special, because if a user specifically requests a certain file be used and error is reported if thie file is not present

func NewDefaultClientConfigLoadingRules

func NewDefaultClientConfigLoadingRules() *ClientConfigLoadingRules

NewDefaultClientConfigLoadingRules returns a ClientConfigLoadingRules object with default fields filled in. You are not required to use this constructor

func (*ClientConfigLoadingRules) IsExplicitFile added in v1.3.0

func (rules *ClientConfigLoadingRules) IsExplicitFile() bool

IsExplicitFile implements ConfigAccess

func (*ClientConfigLoadingRules) Load

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

func (rules *ClientConfigLoadingRules) Migrate() error

Migrate uses the MigrationRules map. If a destination file is not present, then the source file is checked. If the source file is present, then it is copied to the destination file BEFORE any further loading happens.

	GetStartingConfig() (*clientcmdapi.Config, error)
	// GetDefaultFilename returns the name of the file you should write into (create if necessary), if you're trying to create a new stanza as opposed to updating an existing one.
	GetDefaultFilename() string
	// IsExplicitFile indicates whether or not this command is interested in exactly one file.  This implementation only ever does that  via a flag, but implementations that handle local, global, and flags may have more
	IsExplicitFile() bool
	// GetExplicitFile returns the particular file this command is operating against.  This implementation only ever has one, but implementations that handle local, global, and flags may have more

type DeferredLoadingClientConfig

type DeferredLoadingClientConfig struct {
	// contains filtered or unexported fields
}

DeferredLoadingClientConfig is a ClientConfig interface that is backed by a client config loader. It is used in cases where the loading rules may change after you've instantiated them and you want to be sure that the most recent rules are used. This is useful in cases where you bind flags to loading rule parameters before the parse happens and you want your calling code to be ignorant of how the values are being mutated to avoid passing extraneous information down a call stack

	ShortName string
	// Default is the default value for the flag
	Default string
	// Description is the description for the flag
	Description string
}

FlagInfo contains information about how to register a flag. This struct is useful if you want to provide a way for an extender to get back a set of recommended flag names, descriptions, and defaults, but allow for customization by an extender. This makes for coherent extension, without full prescription
