Overview

Example (EmptyConfig) 
defaultConfig := NewConfig()

output, err := yaml.Marshal(defaultConfig)
if err != nil {
	fmt.Printf("Unexpected error: %v", err)
}

fmt.Printf("%v", string(output))

Output:

clusters: {}
contexts: {}

Functions

func FlattenConfig 

func FlattenConfig(config *Config) error

Flatten changes the config object into a self contained config (useful for making secrets)

func FlattenContent 

func FlattenContent(path *string, contents *[]byte, baseDir string) error

func IsConfigEmpty added in v1.2.0 

func IsConfigEmpty(config *Config) bool

IsConfigEmpty returns true if the config is empty.

func MakeAbs 

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

func MinifyConfig 

func MinifyConfig(config *Config) error

MinifyConfig read the current context and uses that to keep only the relevant pieces of config This is useful for making secrets based on kubeconfig files

func ResolvePath 

func ResolvePath(path string, base string) string

func ShortenConfig 

func ShortenConfig(config *Config)

Flatten redacts raw data entries from the config object for a human-readable view.

Types

type AuthInfo 

type AuthInfo struct {
	// LocationOfOrigin indicates where this object came from.  It is used for round tripping config post-merge, but never serialized.
	LocationOfOrigin string
	// ClientCertificate is the path to a client cert file for TLS.
	ClientCertificate string `json:"client-certificate,omitempty"`
	// ClientCertificateData contains PEM-encoded data from a client cert file for TLS. Overrides ClientCertificate
	ClientCertificateData []byte `json:"client-certificate-data,omitempty"`
	// ClientKey is the path to a client key file for TLS.
	ClientKey string `json:"client-key,omitempty"`
	// ClientKeyData contains PEM-encoded data from a client key file for TLS. Overrides ClientKey
	ClientKeyData []byte `json:"client-key-data,omitempty"`
	// Token is the bearer token for authentication to the kubernetes cluster.
	Token string `json:"token,omitempty"`
	// TokenFile is a pointer to a file that contains a bearer token (as described above).  If both Token and TokenFile are present, Token takes precedence.
	TokenFile string `json:"tokenFile,omitempty"`
	// Impersonate is the username to act-as.
	Impersonate string `json:"act-as,omitempty"`
	// Username is the username for basic authentication to the kubernetes cluster.
	Username string `json:"username,omitempty"`
	// Password is the password for basic authentication to the kubernetes cluster.
	Password string `json:"password,omitempty"`
	// AuthProvider specifies a custom authentication plugin for the kubernetes cluster.
	AuthProvider *AuthProviderConfig `json:"auth-provider,omitempty"`
	// Extensions holds additional information. This is useful for extenders so that reads and writes don't clobber unknown fields
	Extensions map[string]runtime.Object `json:"extensions,omitempty"`
}

AuthInfo contains information that describes identity information. This is use to tell the kubernetes cluster who you are.

func NewAuthInfo 

func NewAuthInfo() *AuthInfo

NewConfig is a convenience function that returns a new Config object with non-nil maps

type AuthProviderConfig added in v1.3.0 

type AuthProviderConfig struct {
	Name   string            `json:"name"`
	Config map[string]string `json:"config,omitempty"`
}

AuthProviderConfig holds the configuration for a specified auth provider.

type Cluster 

type Cluster struct {
	// LocationOfOrigin indicates where this object came from.  It is used for round tripping config post-merge, but never serialized.
	LocationOfOrigin string
	// Server is the address of the kubernetes cluster (https://hostname:port).
	Server string `json:"server"`
	// APIVersion is the preferred api version for communicating with the kubernetes cluster (v1, v2, etc).
	APIVersion string `json:"api-version,omitempty"`
	// InsecureSkipTLSVerify skips the validity check for the server's certificate. This will make your HTTPS connections insecure.
	InsecureSkipTLSVerify bool `json:"insecure-skip-tls-verify,omitempty"`
	// CertificateAuthority is the path to a cert file for the certificate authority.
	CertificateAuthority string `json:"certificate-authority,omitempty"`
	// CertificateAuthorityData contains PEM-encoded certificate authority certificates. Overrides CertificateAuthority
	CertificateAuthorityData []byte `json:"certificate-authority-data,omitempty"`
	// Extensions holds additional information. This is useful for extenders so that reads and writes don't clobber unknown fields
	Extensions map[string]runtime.Object `json:"extensions,omitempty"`
}

Cluster contains information about how to communicate with a kubernetes cluster

func NewCluster 

func NewCluster() *Cluster

NewConfig is a convenience function that returns a new Config object with non-nil maps

type Config 

type Config struct {
	// Legacy field from pkg/api/types.go TypeMeta.
	// TODO(jlowdermilk): remove this after eliminating downstream dependencies.
	Kind string `json:"kind,omitempty"`
	// DEPRECATED: APIVersion is the preferred api version for communicating with the kubernetes cluster (v1, v2, etc).
	// Because a cluster can run multiple API groups and potentially multiple versions of each, it no longer makes sense to specify
	// a single value for the cluster version.
	// This field isn't really needed anyway, so we are deprecating it without replacement.
	// It will be ignored if it is present.
	APIVersion string `json:"apiVersion,omitempty"`
	// Preferences holds general information to be use for cli interactions
	Preferences Preferences `json:"preferences"`
	// Clusters is a map of referencable names to cluster configs
	Clusters map[string]*Cluster `json:"clusters"`
	// AuthInfos is a map of referencable names to user configs
	AuthInfos map[string]*AuthInfo `json:"users"`
	// Contexts is a map of referencable names to context configs
	Contexts map[string]*Context `json:"contexts"`
	// CurrentContext is the name of the context that you would like to use by default
	CurrentContext string `json:"current-context"`
	// Extensions holds additional information. This is useful for extenders so that reads and writes don't clobber unknown fields
	Extensions map[string]runtime.Object `json:"extensions,omitempty"`
}

Config holds the information needed to build connect to remote kubernetes clusters as a given user IMPORTANT if you add fields to this struct, please update IsConfigEmpty()

func NewConfig 

func NewConfig() *Config

NewConfig is a convenience function that returns a new Config object with non-nil maps

func (*Config) GetObjectKind added in v1.2.0

func (obj *Config) GroupVersionKind() unversioned.GroupVersionKind

func (*Config) SetGroupVersionKind added in v1.2.0 

func (obj *Config) SetGroupVersionKind(gvk unversioned.GroupVersionKind)

type Context 

type Context struct {
	// LocationOfOrigin indicates where this object came from.  It is used for round tripping config post-merge, but never serialized.
	LocationOfOrigin string
	// Cluster is the name of the cluster for this context
	Cluster string `json:"cluster"`
	// AuthInfo is the name of the authInfo for this context
	AuthInfo string `json:"user"`
	// Namespace is the default namespace to use on unspecified requests
	Namespace string `json:"namespace,omitempty"`
	// Extensions holds additional information. This is useful for extenders so that reads and writes don't clobber unknown fields
	Extensions map[string]runtime.Object `json:"extensions,omitempty"`
}

Context is a tuple of references to a cluster (how do I communicate with a kubernetes cluster), a user (how do I identify myself), and a namespace (what subset of resources do I want to work with)

func NewContext 

func NewContext() *Context

NewConfig is a convenience function that returns a new Config object with non-nil maps

type Preferences 

type Preferences struct {
	Colors bool `json:"colors,omitempty"`
