Overview

Package types holds the definition of the kustomization struct and supporting structs. It's the k8s API conformant object that describes a set of generation and transformation operations to create and/or modify k8s resources. A kustomization file is a serialization of this struct.

Types

type BuiltinPluginLoadingOptions added in v0.3.3 

type BuiltinPluginLoadingOptions int

BuiltinPluginLoadingOptions distinguish ways in which builtin plugins are used. 

const (
	BploUndefined BuiltinPluginLoadingOptions = iota

	// Desired in production use for performance.
	BploUseStaticallyLinked

	// Desired in testing and development cycles where it's undesirable
	// to generate static code.
	BploLoadFromFileSys
)

type ConfigMapArgs 

type ConfigMapArgs struct {
	// GeneratorArgs for the configmap.
	GeneratorArgs `json:",inline,omitempty" yaml:",inline,omitempty"`
}

ConfigMapArgs contains the metadata of how to generate a configmap.

type FieldSelector 

type FieldSelector struct {
	FieldPath string `json:"fieldPath,omitempty" yaml:"fieldPath,omitempty"`
}

FieldSelector contains the fieldPath to an object field. This struct is added to keep the backward compatibility of using ObjectFieldSelector for Var.FieldRef

type FieldSpec 

type FieldSpec struct {
	resid.Gvk          `json:",inline,omitempty" yaml:",inline,omitempty"`
	Path               string `json:"path,omitempty" yaml:"path,omitempty"`
	CreateIfNotPresent bool   `json:"create,omitempty" yaml:"create,omitempty"`
}

FieldSpec completely specifies a kustomizable field in an unstructured representation of a k8s API object. It helps define the operands of transformations.

For example, a directive to add a common label to objects will need to know that a 'Deployment' object (in API group 'apps', any version) can have labels at field path 'spec/template/metadata/labels', and further that it is OK (or not OK) to add that field path to the object if the field path doesn't exist already.

This would look like 

{
  group: apps
  kind: Deployment
  path: spec/template/metadata/labels
  create: true
}

func (FieldSpec) PathSlice 

func (fs FieldSpec) PathSlice() []string

PathSlice converts the path string to a slice of strings, separated by a '/'. Forward slash can be contained in a fieldname. such as ingress.kubernetes.io/auth-secret in Ingress annotations. To deal with this special case, the path to this field should be formatted as 

metadata/annotations/ingress.kubernetes.io\/auth-secret

Then PathSlice will return 

[]string{
   "metadata",
   "annotations",
   "ingress.auth-secretkubernetes.io/auth-secret"
}

func (FieldSpec) String 

func (fs FieldSpec) String() string

type FnPluginLoadingOptions added in v0.4.2

	EnableExec bool
	// Allow to run starlark
	EnableStar bool
	// Allow container access to network
	Network     bool
	NetworkName string
	// list of mounts
	Mounts []string
}

FnPluginLoadingOptions set way functions-based pluing are restricted

func (FsSlice) Less 

func (s FsSlice) Less(i, j int) bool

func (FsSlice) MergeAll 

func (s FsSlice) MergeAll(incoming FsSlice) (result FsSlice, err error)

MergeAll merges the argument into this, returning the result. Items already present are ignored. Items that conflict (primary key matches, but remain data differs) result in an error.

func (FsSlice) MergeOne 

func (s FsSlice) MergeOne(x FieldSpec) (FsSlice, error)

MergeOne merges the argument into this, returning the result. If the item's primary key is already present, and there are no conflicts, it is ignored (we don't want duplicates). If there is a conflict, the merge fails.

func (FsSlice) Swap 

func (s FsSlice) Swap(i, j int)

	// contains filtered or unexported fields
}

type GenerationBehavior 

type GenerationBehavior int

GenerationBehavior specifies generation behavior of configmaps, secrets and maybe other resources. 

const (
	// BehaviorUnspecified is an Unspecified behavior; typically treated as a Create.
	BehaviorUnspecified GenerationBehavior = iota
	// BehaviorCreate makes a new resource.
	BehaviorCreate
	// BehaviorReplace replaces a resource.
	BehaviorReplace
	// BehaviorMerge attempts to merge a new resource with an existing resource.
	BehaviorMerge
)

func NewGenerationBehavior 

func NewGenerationBehavior(s string) GenerationBehavior

NewGenerationBehavior converts a string to a GenerationBehavior.

func (GenerationBehavior) String 

func (b GenerationBehavior) String() string

String converts a GenerationBehavior to a string.

type GeneratorArgs 

type GeneratorArgs struct {
	// Namespace for the configmap, optional
	Namespace string `json:"namespace,omitempty" yaml:"namespace,omitempty"`

	// Name - actually the partial name - of the generated resource.
	// The full name ends up being something like
	// NamePrefix + this.Name + hash(content of generated resource).
	Name string `json:"name,omitempty" yaml:"name,omitempty"`

	// Behavior of generated resource, must be one of:
	//   'create': create a new one
	//   'replace': replace the existing one
	//   'merge': merge with the existing one
	Behavior string `json:"behavior,omitempty" yaml:"behavior,omitempty"`

	// KvPairSources for the generator.
	KvPairSources `json:",inline,omitempty" yaml:",inline,omitempty"`

	// Local overrides to global generatorOptions field.
	Options *GeneratorOptions `json:"options,omitempty" yaml:"options,omitempty"`
}

GeneratorArgs contains arguments common to ConfigMap and Secret generators.

type GeneratorOptions 

type GeneratorOptions struct {
	// Labels to add to all generated resources.
	Labels map[string]string `json:"labels,omitempty" yaml:"labels,omitempty"`

	// Annotations to add to all generated resources.
	Annotations map[string]string `json:"annotations,omitempty" yaml:"annotations,omitempty"`

	// DisableNameSuffixHash if true disables the default behavior of adding a
	// suffix to the names of generated resources that is a hash of the
	// resource contents.
	DisableNameSuffixHash bool `json:"disableNameSuffixHash,omitempty" yaml:"disableNameSuffixHash,omitempty"`
}

GeneratorOptions modify behavior of all ConfigMap and Secret generators.

func MergeGlobalOptionsIntoLocal added in v0.3.3 

func MergeGlobalOptionsIntoLocal(
	localOpts *GeneratorOptions,
	globalOpts *GeneratorOptions) *GeneratorOptions

MergeGlobalOptionsIntoLocal merges two instances of GeneratorOptions. Values in the first 'local' argument cannot be overridden by the second 'global' argument, except in the case of booleans.

With booleans, there's no way to distinguish an 'intentional' false from 'default' false. So the rule is, if the global value of the value of a boolean is true, i.e. disable, it trumps the local value. If the global value is false, then the local value is respected. Bottom line: a local false cannot override a global true.

boolean fields are always a bad idea; should always use enums instead.

type Image 

type Image struct {
	// Name is a tag-less image name.
	Name string `json:"name,omitempty" yaml:"name,omitempty"`

	// NewName is the value used to replace the original name.

	// NewTag is the value used to replace the original tag.

	// Digest is the value used to replace the original image tag.
	// If digest is present NewTag value is ignored.
	Digest string `json:"digest,omitempty" yaml:"digest,omitempty"`
}

Image contains an image name, a new name, a new tag or digest, which will replace the original name and tag.

	Type      string   `json:"type,omitempty" yaml:"type,omitempty"`
	ConfigMap NameArgs `json:"configMap,omitempty" yaml:"configMap,omitempty"`
