Documentation

Overview

helpers package provides some general functions that do not have a good home

helpers package provides different functionality

helpers module creates a strategy to determine, where to put the files we copy from the cluster.

Types

type CollectedFile

type CollectedFile struct {
	Path string `json:"path"`
	Size int64  `json:"size"`
}

type CopyStrategyHC

type CopyStrategyHC struct {
	StrategyName string     // the name of the output strategy (defasult, healthcheck etc)
	TmpDir       string     // tmp dir used for staging files
	BaseDir      string     // the base dir of where the output is routed
	Fs           Filesystem // filesystem interface (so we can pass in realof fake filesystem, assists testing)
	TimeService  TimeService
}
