Functions

func Copy 

func Copy(dst *websocket.Conn, src *websocket.Conn) (int64, error)

func CopyFrom 

func CopyFrom(dst io.Writer, src *websocket.Conn) (written int64, err error)

func CopyTo 

func CopyTo(dst *websocket.Conn, src io.Reader) (written int64, err error)

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 the kubeconfig itself. This is done with the following hierarchy rules:

  3. CommandLineLocation - this parsed from the command line, so it must be late bound. If you specify this, then no other kubeconfig files are merged. This file must exist.

  4. If $KUBECONFIG is set, then it is treated as a list of files that should be merged.

  5. 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.

  6. Determine the context to use based on the first hit in this chain

  7. command line argument - again, parsed from the command line, so it must be late bound

  8. CurrentContext from the merged kubeconfig file

  9. Empty is allowed at this stage

  10. 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)

  11. command line argument

  12. If context is present, then use the context value

  13. Empty is allowed

  14. 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:

  15. command line argument

  16. If cluster info is present and a value for the attribute is present, use it.

  17. If you don't have a server location, bail.

  18. 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:

  19. If there are two conflicting techniques specified from the command line, fail.

  20. If the command line does not specify one, and the auth info has conflicting techniques, fail.

  21. If the command line specifies one and the auth info specifies another, honor the command line technique.

  22. Use default values and potentially prompt for auth information

    However, if it appears that we're running in a kubernetes cluster container environment, then run with the auth info kubernetes mounted for us. Specifically: The env vars KUBERNETES_SERVICE_HOST and KUBERNETES_SERVICE_PORT are set, and the file /var/run/secrets/kubernetes.io/serviceaccount/token exists and is not a directory.
