Types

type CommandSources

type CommandSources struct {
	// Map of keys to commands to generate the values
	Commands map[string]string `json:"commands,omitempty" yaml:"commands,omitempty"`
	// EnvCommand to output lines of key=val pairs to create a secret.
	// i.e. a Docker .env file or a .ini file.
	EnvCommand string `json:"envCommand,omitempty" yaml:"envCommand,omitempty"`
}

CommandSources contains some generic sources for secrets.

type ConfigMapArgs

type ConfigMapArgs struct {
	// Name of the configmap.
	// The full name should be Kustomization.NamePrefix + Configmap.Name +
	// hash(content of configmap).
	Name string `json:"name,omitempty" yaml:"name,omitempty"`

	// behavior of configmap, must be one of create, merge and replace
	// 'create': create a new one;
	// 'replace': replace the existing one;
	// 'merge': merge the existing one.
	Behavior string `json:"behavior,omitempty" yaml:"behavior,omitempty"`

	// DataSources for configmap.
	DataSources `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.
	EnvSource string `json:"env,omitempty" yaml:"env,omitempty"`
}

DataSources contains some generic sources for configmaps.

type ImageTag

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

	// NewTag is the value to use in replacing the original tag.
	NewTag string `json:"newTag,omitempty" yaml:"newTag,omitempty"`
}

ImageTag contains an image and a new tag, which will replace the original tag.

type Kustomization

type Kustomization struct {
	// NamePrefix will prefix the names of all resources mentioned in the kustomization
	// file including generated configmaps and secrets.
	NamePrefix string `json:"namePrefix,omitempty" yaml:"namePrefix,omitempty"`

	// Namespace to add to all objects.
	Namespace string `json:"namespace,omitempty" yaml:"namespace,omitempty"`

	// Labels to add to all objects and selectors.
	// These labels would also be used to form the selector for apply --prune
	// Named differently than “labels” to avoid confusion with metadata for
	// this object
	CommonLabels map[string]string `json:"commonLabels,omitempty" yaml:"commonLabels,omitempty"`

	// Annotations to add to all objects.
	CommonAnnotations map[string]string `json:"commonAnnotations,omitempty" yaml:"commonAnnotations,omitempty"`

	// Each entry should be either a path to a file with a name matching the value of
	// constants.KustomizationFileName, or a path to a directory containing a file with that name.
	Bases []string `json:"bases,omitempty" yaml:"bases,omitempty"`

	// Resources specifies the relative paths within the package.
	// It could be any format that kubectl -f allows, i.e. files, directories,
	// URLs and globs.
	Resources []string `json:"resources,omitempty" yaml:"resources,omitempty"`

	// Crds specifies relative paths to custom resource definition files.
	Crds []string `json:"crds,omitempty" yaml:"crds,omitempty"`

	// An Patch entry is very similar to an Resource entry.
	// It specifies the relative paths within the package, and could be any
	// format that kubectl -f allows.
	// It should be able to be merged by Strategic Merge Patch on top of its
	// corresponding base resource.
	Patches []string `json:"patches,omitempty" yaml:"patches,omitempty"`

	// List of configmaps to generate from configuration sources.
	// Base/overlay concept doesn't apply to this field.
	// If a configmap want to have a base and an overlay, it should go to Bases
	// and Overlays fields.
	ConfigMapGenerator []ConfigMapArgs `json:"configMapGenerator,omitempty" yaml:"configMapGenerator,omitempty"`

	// List of secrets to generate from secret commands.
	// Base/overlay concept doesn't apply to this field.
	// If a secret want to have a base and an overlay, it should go to Bases and
	// Overlays fields.
	SecretGenerator []SecretArgs `json:"secretGenerator,omitempty" yaml:"secretGenerator,omitempty"`

	// Variables which will be substituted at runtime
	Vars []Var `json:"vars,omitempty" yaml:"vars,omitempty"`

	// If set to true, all images need to have tags
	RequireTag bool `json:"requireTag,omitempty" yaml:"requireTag,omitempty"`

	// ImageTags is a list of ImageTag for changing image tags
	ImageTags []ImageTag `json:"imageTags,omitempty" yaml:"imageTags,omitempty"`
}

Kustomization holds the information needed to generate customized k8s api resources.

type SecretArgs

type SecretArgs struct {
	// Name of the secret.
	// The full name should be Kustomization.NamePrefix + SecretGenerator.Name +
	// hash(content of secret).
	Name string `json:"name,omitempty" yaml:"name,omitempty"`

	// behavior of secretGenerator, must be one of create, merge and replace
	// 'create': create a new one;
	// 'replace': replace the existing one;
	// 'merge': merge the existing one.
	Behavior string `json:"behavior,omitempty" yaml:"behavior,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 "Commands" must have exactly two
	// keys: "tls.key" and "tls.crt"
	Type string `json:"type,omitempty" yaml:"type,omitempty"`

	// CommandSources for secret.
	CommandSources `json:",inline,omitempty" yaml:",inline,omitempty"`
}

SecretArgs contains the metadata of how to generate a secret.

type Var

type Var struct {
	// Value of identifier name e.g. FOO used in container args, annotations
	// Appears in pod template as $(FOO)
	Name string `json:"name" yaml:"name"`

	// ObjRef must refer to a Kubernetes resource under the
	// purview of this kustomization. ObjRef should use the
	// raw name of the object (the name specified in its YAML,
	// before addition of a namePrefix).
	ObjRef corev1.ObjectReference `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: metadata.name
	FieldRef corev1.ObjectFieldSelector `json:"fieldref,omitempty" yaml:"objref,omitempty"`
}

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

func (*Var) Defaulting

func (v *Var) Defaulting()

Defaulting sets reference to field used by default.
