Functions

func DealWithDeprecatedFields

func DealWithDeprecatedFields(data []byte) []byte

DealWithDeprecatedFields should be called immediately after loading from storage.

Types

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 DataSources

type DataSources struct {
	// LiteralSources is a list of literal sources.
	// Each literal source should be a key and literal value,
	// e.g. `somekey=somevalue`
	// It will be similar to kubectl create configmap|secret --from-literal
	LiteralSources []string `json:"literals,omitempty" yaml:"literals,omitempty"`

	// FileSources is a list of file sources.
	// Each file source can be specified using its file path, in which case file
	// basename will be used as configmap key, or optionally with a key and file
	// path, in which case the given key will be used.
	// Specifying a directory will iterate each named file in the directory
	// whose basename is a valid configmap key.
	// It will be similar to kubectl create configmap|secret --from-file
	FileSources []string `json:"files,omitempty" yaml:"files,omitempty"`

	// EnvSource format should be a path to a file to read lines of key=val
	// pairs to create a configmap.
	// i.e. a Docker .env file or a .ini file.

}

DataSources contains some generic sources for configmaps.

type FieldSelector added in v1.0.9

type FieldSelector struct {

1) GenArgs is not nil
2) DisableNameSuffixHash in GeneratorOptions is not set to true

func (*GenArgs) String

func (g *GenArgs) String() string

type GenerationBehavior

type GenerationBehavior int

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

	// suffix to the names of generated resources that is a hash of the
	// resource contents.

}

GeneratorOptions modify behavior of all ConfigMap and Secret generators.

	// for changing image names, tags or digests. This can also be achieved with a
	// patch, but this operator is simpler to specify.
	Images []image.Image `json:"images,omitempty" yaml:"images,omitempty"`

	// Vars allow things modified by kustomize to be injected into a
	// container specification. A var is a name (e.g. FOO) associated
	// with a field in a specific resource instance.  The field must
	// contain a value of type string, and defaults to the name field
	// of the instance.  Any appearance of "$(FOO)" in the container

	// ConfigMapGenerator is a list of configmaps to generate from
	// local data (one configMap per list item).
	// The resulting resource is a normal operand, subject to
	// name prefixing, patching, etc.  By default, the name of
	// the map will have a suffix hash generated from its contents.
	ConfigMapGenerator []ConfigMapArgs `json:"configMapGenerator,omitempty" yaml:"configMapGenerator,omitempty"`

	// SecretGenerator is a list of secrets to generate from
	// local data (one secret per list item).
	// The resulting resource is a normal operand, subject to
	// name prefixing, patching, etc.  By default, the name of
	// the map will have a suffix hash generated from its contents.
	SecretGenerator []SecretArgs `json:"secretGenerator,omitempty" yaml:"secretGenerator,omitempty"`

	// GeneratorArgs for the secret.
	GeneratorArgs `json:",inline,omitempty" yaml:",inline,omitempty"`

	// Type of the secret.
	//
	// This is the same field as the secret type field in v1/Secret:
	// It can be "Opaque" (default), or "kubernetes.io/tls".
	//
	// If type is "kubernetes.io/tls", then "literals" or "files" must have exactly two
	// keys: "tls.key" and "tls.crt"
	Type string `json:"type,omitempty" yaml:"type,omitempty"`
}

SecretArgs contains the metadata of how to generate a secret.

type Target added in v1.0.9

	ObjRef Target `json:"objref" yaml:"objref"`

	// FieldRef refers to the field of the object referred to by
	// ObjRef whose value will be extracted for use in
	// replacing $(FOO).
	// If unspecified, this defaults to fieldPath: $defaultFieldPath
	FieldRef FieldSelector `json:"fieldref,omitempty" yaml:"fieldref,omitempty"`
}

Var represents a variable whose value will be sourced from a field in a Kubernetes object.
