Overview

Package utils -- Utility functions to be used throughout cmd. Kind of decided that this was a pretty decent way of doing shared logic for

cmd.

Basically the same as for pkg, so nothing too special there, but since cmd

has a bit of nesting, it brings up some more questions.

It seems like golang itself does a pattern like this for `base` cmd units,

so this is probably not too shabby.

Functions

func GetAnyMaster

func GetAnyMaster() (hope.Node, error)

func GetAvailableMasters

func GetAvailableMasters() ([]hope.Node, error)

GetAvailableMasters -- Returns the list of master nodes that can be reached

in one way or another.

Doesn't confirm if the masters are configured, or are in the load balanced

set of masters; only that the node exists on its defined hypervisor.

func GetHypervisor

func GetHypervisor(name string) (hypervisors.Hypervisor, error)

func GetHypervisors

func GetHypervisors() ([]hypervisors.Hypervisor, error)

func GetIdentifiableResources

func GetIdentifiableResources(names *[]string, tags *[]string) (*[]hope.Resource, error)

func GetJob

func GetJob(jobName string) (*hope.Job, error)

func GetJobs

func GetJobs() (*[]hope.Job, error)

func GetLoadBalancer

func GetLoadBalancer() (hope.Node, error)

func GetNode

func GetNode(name string) (hope.Node, error)

func GetResources

func GetResources() (*[]hope.Resource, error)

func GetVMs

func GetVMs() (*hope.VMs, error)

func HasNode

func HasNode(name string) bool

HasNode -- Check whether a node has been defined in the hope file, even if

the node doesn't exist on its hypervisor yet.

func KubectlFromAnyMaster

func KubectlFromAnyMaster() (*kubeutil.Kubectl, error)

func ReplaceParametersInDirectoryCopy

func ReplaceParametersInDirectoryCopy(dir string, parameters []string) (string, error)

ReplaceParametersInDirectoryCopy - Copy the provided directory, and replace

parameters in the files.

Returns the temp path to the copied directory, and the caller must clean up

that directory itself, unless an error occurs.

func ReplaceParametersInFile

func ReplaceParametersInFile(path string, parameters []string) (string, error)

func ReplaceParametersInString

func ReplaceParametersInString(str string, parameters []string) (string, error)

func ReplaceParametersWithSubstitutor

func ReplaceParametersWithSubstitutor(t *hope.TextSubstitutor, parameters []string) (string, error)

func VMSpec

func VMSpec(vmName string) (*hope.VMImageSpec, error)
