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/vmware-tanzu/sonobuoy/pkg/client"
	"github.com/vmware-tanzu/sonobuoy/pkg/config"
	"github.com/vmware-tanzu/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{
			PluginEnvOverrides: map[string]map[string]string{
				"e2e": {"E2E_FOCUS": "[sig-networking]"},
			},
			Config:          config.New(),
			EnableRBAC:      true,
			ImagePullPolicy: "Always",
		},
	}

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

}

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.

NewReader returns a configured Reader.

func (*Reader) Read

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.

type RetrieveConfig 

type RetrieveConfig struct {
	// Namespace is the namespace the sonobuoy aggregator is running in.

func (*SonobuoyClient) GetStatus 

func (c *SonobuoyClient) GetStatus(cfg *StatusConfig) (*aggregation.Status, error)

GetStatus returns the aggregation status that is set as an annotation on the aggregator pod. Returns an error if unable to find the namespace, pod, or annotation. Use GetStatusPod to also return the pod itself so that you can better understand the state of the system.
