Functions

func DefaultClientConfig 

func DefaultClientConfig(flags *pflag.FlagSet) clientcmd.ClientConfig

DefaultClientConfig creates a clientcmd.ClientConfig with the following hierarchy:

  1. Use the kubeconfig builder. The number of merges and overrides here gets a little crazy. Stay with me.
  2. Merge together the kubeconfig itself. This is done with the following hierarchy and merge rules:
  3. CommandLineLocation - this parsed from the command line, so it must be late bound
  4. EnvVarLocation
  5. CurrentDirectoryLocation
  6. HomeDirectoryLocation Empty filenames are ignored. Files with non-deserializable content produced errors. The first file to set a particular value or map key wins and the value or map key is never changed. This means that the first file to set CurrentContext will have its context preserved. 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.
  7. Determine the context to use based on the first hit in this chain
  8. command line argument - again, parsed from the command line, so it must be late bound
  9. CurrentContext from the merged kubeconfig file
  10. Empty is allowed at this stage
  11. Determine the cluster info and auth info to use. At this point, we may or may not have a context. They are built based on the first hit in this chain. (run it twice, once for auth, once for cluster)
  12. command line argument
  13. If context is present, then use the context value
  14. Empty is allowed
  15. Determine the actual cluster info to use. At this point, we may or may not have a cluster info. Build each piece of the cluster info based on the chain:
  16. command line argument
  17. If cluster info is present and a value for the attribute is present, use it.
  18. If you don't have a server location, bail.
  19. Auth info is build using the same rules as cluster info, EXCEPT that you can only have one authentication technique per auth info. The following conditions result in an error:
  20. If there are two conflicting techniques specified from the command line, fail.
  21. If the command line does not specify one, and the auth info has conflicting techniques, fail.
  22. If the command line specifies one and the auth info specifies another, honor the command line technique.
  23. Use default values and potentially prompt for auth information

Types

type Factory 

type Factory struct {

	// Returns interfaces for dealing with arbitrary runtime.Objects.
	Object func() (meta.RESTMapper, runtime.ObjectTyper)
	// Returns a client for accessing Kubernetes resources or an error.
	Client func() (*client.Client, error)
	// Returns a client.Config for accessing the Kubernetes server.
	ClientConfig func() (*client.Config, error)
	// Returns a RESTClient for working with the specified RESTMapping or an error. This is intended
	// for working with arbitrary resources and is not guaranteed to point to a Kubernetes APIServer.
	RESTClient func(mapping *meta.RESTMapping) (resource.RESTClient, error)
	// Returns a Describer for displaying the specified RESTMapping type or an error.
	Describer func(mapping *meta.RESTMapping) (kubectl.Describer, error)

	DefaultNamespace func() (string, error)
	// contains filtered or unexported fields
}

Factory provides abstractions that allow the Kubectl command to be extended across multiple types of resources and different API sets. TODO: make the functions interfaces TODO: pass the various interfaces on the factory directly into the command constructors (so the commands are decoupled from the factory).

func NewFactory 

func NewFactory(optionalClientConfig clientcmd.ClientConfig) *Factory
