Overview

OpenShift v3 Diagnostics

This is a tool to help administrators and users resolve common problems that occur with OpenShift v3 deployments. It will likely remain under continuous development as the OpenShift Origin project progresses.

The goals of the diagnostics tool are summarized in the Trello card https://trello.com/c/LdUogKuN; Diagnostics are included as an `openshift` sub-command that analyzes OpenShift as it is able, whether from the perspective of an OpenShift client or on an OpenShift host.

View pkg/diagnostics/README.md for more details on developing diagnostics.

Functions

func NewCmdDiagnostics

func NewCmdDiagnostics(name string, fullName string, f genericclioptions.RESTClientGetter, streams genericclioptions.IOStreams) *cobra.Command

NewCmdDiagnostics is the base command for running a standard set of diagnostics with generic options only.

func NewCmdDiagnosticsAll

func NewCmdDiagnosticsAll(name string, fullName string, f genericclioptions.RESTClientGetter, streams genericclioptions.IOStreams, available types.DiagnosticList) *cobra.Command

NewCmdDiagnosticsAll is the command for running ALL diagnostics and providing all flags.

func NewCmdDiagnosticsIndividual

func NewCmdDiagnosticsIndividual(name string, fullName string, f genericclioptions.RESTClientGetter, streams genericclioptions.IOStreams, diagnostic types.Diagnostic) *cobra.Command

NewCmdDiagnosticsIndividual is a parameterized subcommand providing a single diagnostic and its flags.

Types

type DiagnosticsOptions

type DiagnosticsOptions struct {
	// list of diagnostic name(s) to run
	RequestedDiagnostics sets.String
	// flag bindings for any diagnostics that require them
	ParameterizedDiagnostics types.ParameterizedDiagnosticMap

	// list available diagnostics and exit
	ListAll bool
	// specify locations of host config files
	MasterConfigLocation string
	NodeConfigLocation   string
	// indicate this is an openshift host despite lack of other indicators
	IsHost bool
	// When true, prevent diagnostics from changing API state (e.g. creating something)
	PreventModification bool
	// We need a factory for creating clients. Creating a factory
	// creates flags as a byproduct, most of which we don't want.
	// The command creates these and binds only the flags we want.
	ClientFlags *flag.FlagSet
	Factory     genericclioptions.RESTClientGetter
	// specify context name to be used for cluster-admin access
	ClientClusterContext string
	// LogOptions determine globally what the user wants to see and how.
	LogOptions *log.LoggerOptions
	// contains filtered or unexported fields
}

DiagnosticsOptions holds values received from command line flags as well as other objects generated for the command to operate.

func (*DiagnosticsOptions) Complete

func (o *DiagnosticsOptions) Complete(c *cobra.Command, args []string) error

Complete fills in DiagnosticsConfig needed if the command is actually invoked.

func (*DiagnosticsOptions) Logger

func (o *DiagnosticsOptions) Logger() *log.Logger

returns the logger built according to options (must be Complete()ed)

func (DiagnosticsOptions) RunDiagnostics

func (o DiagnosticsOptions) RunDiagnostics() error

RunDiagnostics builds diagnostics based on the options and executes them. Returns: error (raised during construction of diagnostics; may be an aggregate error object),
