This is a copy of the upstream OTeL Collector Contrib internal/k8sconfig package, here.

This is necessary to prevent failure to import the internal package in the main package.

Functions

func CreateRestConfig

func CreateRestConfig(apiConf APIConfig) (*rest.Config, error)

CreateRestConfig creates an Kubernetes API config from user configuration.

func MakeClient

func MakeClient(apiConf APIConfig) (k8s.Interface, error)

MakeClient can take configuration if needed for other types of auth

func MakeDynamicClient

func MakeDynamicClient(apiConf APIConfig) (dynamic.Interface, error)

MakeDynamicClient can take configuration if needed for other types of auth

func MakeOpenShiftQuotaClient

func MakeOpenShiftQuotaClient(apiConf APIConfig) (quotaclientset.Interface, error)

MakeOpenShiftQuotaClient can take configuration if needed for other types of auth and return an OpenShift quota API client

Types

type APIConfig

type APIConfig struct {
	// How to authenticate to the K8s API server.  This can be one of `none`
	// (for no auth), `serviceAccount` (to use the standard service account
	// token provided to the agent pod), or `kubeConfig` to use credentials
	// from `~/.kube/config`.
	AuthType AuthType `mapstructure:"auth_type"`

	// When using auth_type `kubeConfig`, override the current context.
	Context string `mapstructure:"context"`
}

APIConfig contains options relevant to connecting to the K8s API

func (APIConfig) Validate

func (c APIConfig) Validate() error

Validate validates the K8s API config

type AuthType

type AuthType string

AuthType describes the type of authentication to use for the K8s API

const (
	// AuthTypeNone means no auth is required
	AuthTypeNone AuthType = "none"
	// AuthTypeServiceAccount means to use the built-in service account that
	// K8s automatically provisions for each pod.
	AuthTypeServiceAccount AuthType = "serviceAccount"
	// AuthTypeKubeConfig uses local credentials like those used by kubectl.
	AuthTypeKubeConfig AuthType = "kubeConfig"
	// AuthTypeTLS indicates that client TLS auth is desired
	AuthTypeTLS AuthType = "tls"
)

TODO: Add option for TLS once https://go.opentelemetry.io/collector/issues/933 is addressed.
