Overview

Package client provides primitives for interacting with Sonobuoy and the results archive.

Example

Example shows how to create a client and run Sonobuoy. 

package main

import (
	"github.com/heptio/sonobuoy/pkg/client"
	"github.com/heptio/sonobuoy/pkg/config"
	"github.com/heptio/sonobuoy/pkg/dynamic"
	"k8s.io/client-go/rest"
)

// Get a rest config from somewhere.
var cfg *rest.Config

// Example shows how to create a client and run Sonobuoy.
func main() {
	// Get an APIHelper with default implementations from client-go.
	apiHelper, err := dynamic.NewAPIHelperFromRESTConfig(cfg)
	if err != nil {
		panic(err)
	}

	// client.NewSonobuoyClient returns a struct that implements the client.Interface.
	sonobuoy, err := client.NewSonobuoyClient(cfg, apiHelper)
	if err != nil {
		panic(err)
	}

	// Each feature of Sonobuoy requires a config to customize the behavior.

	// Build up a RunConfig struct.
	// The command line client provides default values with override flags.
	runConfig := client.RunConfig{
		GenConfig: client.GenConfig{
			E2EConfig: &client.E2EConfig{
				Focus: "[sig-networking]",
				Skip:  "",
			},
			Config:          config.New(),
			Image:           config.DefaultImage,
			Namespace:       config.DefaultNamespace,
			EnableRBAC:      true,
			ImagePullPolicy: "Always",
		},
	}

	// Runs sonobuoy on the cluster configured in $HOME/.kube/config.
	if err = sonobuoy.Run(&runConfig); err != nil {
		panic(err)
	}
}

	EnableRBAC bool
	DeleteAll  bool
}

	Skip     string
	Parallel string
}

E2EConfig is the configuration of the E2E tests.

type GenConfig 

type GenConfig struct {
	E2EConfig            *E2EConfig
	Config               *config.Config

func NewGenConfig 

func NewGenConfig() *GenConfig

type Interface 

type Interface interface {
	// Run generates the manifest, then tries to apply it to the cluster.
	// returns created resources or an error
	Run(cfg *RunConfig) error
	// GenerateManifest fills in a template with a Sonobuoy config
	GenerateManifest(cfg *GenConfig) ([]byte, error)
	// RetrieveResults copies results from a sonobuoy run into a Reader in tar format.
	RetrieveResults(cfg *RetrieveConfig) (io.Reader, <-chan error)
	// GetStatus determines the status of the sonobuoy run in order to assist the user.
	GetStatus(namespace string) (*aggregation.Status, error)
	// LogReader returns a reader that contains a merged stream of sonobuoy logs.
	LogReader(cfg *LogConfig) (*Reader, error)
	// Delete removes a sonobuoy run, namespace, and all associated resources.
	Delete(cfg *DeleteConfig) error
	// PreflightChecks runs a number of preflight checks to confirm the environment is good for Sonobuoy
	PreflightChecks(cfg *PreflightConfig) []error
}

Interface is the main contract that we will give to external consumers of this library This will provide a consistent look/feel to upstream and allow us to expose sonobuoy behavior to other automation systems.

type LogConfig 

type LogConfig struct {
	// Follow determines if the logs should be followed or not (tail -f).
	Follow bool
	// Namespace is the namespace the sonobuoy aggregator is running in.
	Namespace string
	// Out is the writer to write to.
	Out io.Writer
}

LogConfig are the input options for viewing a Sonobuoy run's logs.

func NewLogConfig 

func NewLogConfig() *LogConfig

NewLogConfig is a LogConfig with follow disabled and default images.

type Mode 

type Mode string

Mode identifies a specific mode of running Sonobuoy. A mode is a defined configuration of plugins and E2E Focus and Config. Modes form the base level defaults, which can then be overriden by the e2e flags and the config flag. 

const (
	// Quick runs a single E2E test and the systemd log tests.
	Quick Mode = "Quick"
	// Conformance runs all of the E2E tests and the systemd log tests.
	Conformance Mode = "Conformance"
	// Extended run all of the E2E tests, the systemd log tests, and
	// Heptio's E2E Tests.
	Extended Mode = "Extended"
)

func (*Mode) Get 

func (m *Mode) Get() *ModeConfig

Get returns the ModeConfig associated with a mode name, or nil if there's no associated mode

func (*Mode) Set 

func (m *Mode) Set(str string) error

Set the name with a given string. Returns error on unknown mode.

func (*Mode) String 

func (m *Mode) String() string

String needed for pflag.Value

func (*Mode) Type

type Reader 

type Reader struct {
	// contains filtered or unexported fields
}

Reader provides an io.Reader interface to a channel of bytes. The first error received on the error channel will be returned by Read after the bytestream is drained and on all subsequent calls to Read. It is the responsibility of the program writing to bytestream to write an io.EOF to the error stream when it is done and close all channels.

func NewReader 

func NewReader(bytestream chan []byte, errc chan error) *Reader

NewReader returns a configured Reader.

func (*Reader) Read 

func (r *Reader) Read(p []byte) (int, error)

Read tries to fill up the passed in byte slice with messages from the channel. Read manages the message overflow ensuring no bytes are missed. If an error is set on the reader it will return the error immediately.
