Package env provides functions to incorporate environment variables into kubectl commands.

Package openapi is a collection of libraries for fetching the openapi spec from a Kubernetes server and then indexing the type definitions.

AddDryRunFlag adds dry-run flag to a command.

AddGeneratorFlags adds flags common to resource generation commands TODO: need to take a pass at other generator commands to use this set of flags.

AddNoHeadersFlags adds no-headers flags to a command.

AddNonDeprecatedPrinterFlags supports the conversion case which must logically have output-version.

AddOutputFlags adds output related flags to a command.

AddOutputFlagsForMutation adds output related flags to a command.

AddOutputVarFlagsForMutation adds output related flags to a command.

AddPrinterFlags adds printing related flags to a command (e.g.

AddSourceToErr adds handleResourcePrefix and source string to error message.

BehaviorOnFatal allows you to override the default behavior when a fatal error occurs, which is to call os.Exit(code).

ChangeResourcePatch creates a patch between the origin input resource info and the annotated with change-cause input resource info.

CheckErr prints a user friendly error to STDERR and exits with a non-zero exit code.

ContainsChangeCause checks if input resource info contains change-cause annotation.

DefaultBehaviorOnFatal allows you to undo any previous override.

DefaultClientConfig creates a clientcmd.ClientConfig with the following hierarchy: 1.

DefaultGenerators returns the set of default generators for use in Factory instances.

DefaultSubCommandRun prints a command's help string to the specified output if no arguments (sub-commands) are provided, or a usage error otherwise.

DumpReaderToFile writes all data from the given io.Reader to the specified file (usually for temporary use).

ExtractCmdPrintOptions parses printer specific commandline args and returns a PrintOptions object.

fallbackGeneratorNameIfNecessary returns the name of the old generator if server does not support new generator.

FilterResourceList receives a list of runtime objects.

GetFirstPod returns a pod matching the namespace and label selector and the number of all pods that match the label selector.

Assumes the flag has a default value.

Assumes the flag has a default value.

Assumes the flag has a default value.

GetFlagStringArray can be used to accept multiple argument with flag repetition (e.g.

GetFlagStringSlice can be used to accept multiple argument with flag repetition (e.g.

GetResourcesAndPairs retrieves resources and "KEY=VALUE or KEY-" pair args from given args.

GetWideFlag is used to determine if "-o wide" is used.

IsSiblingCommandExists receives a pointer to a cobra command and a target string.

ManualStrip is used for dropping comments from a YAML file.

Merge requires JSON serialization TODO: merge assumes JSON serialization, and does not properly abstract API retrieval.

MultilineError returns a string representing an error that splits sub errors into their own lines.

MultipleErrors returns a newline delimited string containing the prefix and referenced errors in standard form.

MustPrintWithKinds determines if printer is dealing with multiple resource kinds, in which case it will return true, indicating resource kind will be included as part of printer output.

NewCachedDiscoveryClient creates a new DiscoveryClient.

NewClientAccessFactoryFromDiscovery allows an external caller to substitute a different discoveryFactory Which allows for the client cache to be built in ring0, but still rely on a custom discovery client.

NewFactory creates a factory with the default Kubernetes resources defined if optionalClientConfig is nil, then flags will be bound to a new clientcmd.ClientConfig.

OutputsRawFormat determines if a command's output format is machine parsable or returns false if it is human readable (name, wide, etc.).

ParsePairs retrieves new and remove pairs (if supportRemove is true) from "KEY=VALUE or KEY-" pair args.

PrintErrorWithCauses prints an error's kind, name, and each of the error's causes in a new line.

PrintFilterCount displays informational messages based on the number of resources found, hidden, or config flags shown.

RecordChangeCause annotate change-cause to input runtime object.

RequireNoArguments exits with a usage error if extra arguments are provided.

ShouldIncludeUninitialized identifies whether to include uninitialized objects.

ShouldRecord checks if we should record current change cause.

StandardErrorMessage translates common errors into a human readable message, or returns false if the error is not one of the recognized types.

StripComments will transform a YAML file into JSON, thus dropping any comments in it.

UpdateObject updates resource object with updateFn.

Retrieve a list of handled resources from printer as valid args TODO: This function implementation should be replaced with a real implementation from the discovery service.

ValidateOutputArgs validates -o flag args for mutations.

ValidResourceTypeList returns a multi-line string containing the valid resources.

TODO(sig-cli): Enforce consistent naming for generators here.

ErrExit may be passed to CheckError to instruct it to output nothing but exit with status code 1.

CachedDiscoveryClient implements the functions that discovery server-supported API groups, versions and resources.

ClientCache caches previously loaded clients for reuse, and ensures MatchServerVersion is invoked only once.

BuilderFactory holds the third level of factory methods.

ClientAccessFactory holds the first level of factory methods.

Factory provides abstractions that allow the Kubectl command to be extended across multiple types of resources and different API sets.

ObjectMappingFactory holds the second level of factory methods.
