Overview

Package builtinconfig provides legacy methods for configuring builtin plugins from a common config file. As a user, its best to configure plugins individually with plugin config files specified in the `transformers:` or `generators:` field, than to use this legacy configuration technique.

Types

type NameBackReferences

type NameBackReferences struct {
	resid.Gvk  `json:",inline,omitempty" yaml:",inline,omitempty"`
	FieldSpecs types.FsSlice `json:"FieldSpecs,omitempty" yaml:"FieldSpecs,omitempty"`
}

NameBackReferences is an association between a gvk.GVK and a list of FieldSpec instances that could refer to it.

It is used to handle name changes, and can be thought of as a a contact list. If you change your own contact info (name, phone number, etc.), you must tell your contacts or they won't know about the change.

For example, ConfigMaps can be used by Pods and everything that contains a Pod; Deployment, Job, StatefulSet, etc. To change the name of a ConfigMap instance from 'alice' to 'bob', one must visit all objects that could refer to the ConfigMap, see if they mention 'alice', and if so, change the reference to 'bob'.

The NameBackReferences instance to aid in this could look like

{
  kind: ConfigMap
  version: v1
  FieldSpecs:
  - kind: Pod
    version: v1
    path: spec/volumes/configMap/name
  - kind: Deployment
    path: spec/template/spec/volumes/configMap/name
  - kind: Job
    path: spec/template/spec/volumes/configMap/name
    (etc.)
}

type TransformerConfig

type TransformerConfig struct {
	NamePrefix        types.FsSlice `json:"namePrefix,omitempty" yaml:"namePrefix,omitempty"`
	NameSuffix        types.FsSlice `json:"nameSuffix,omitempty" yaml:"nameSuffix,omitempty"`
	NameSpace         types.FsSlice `json:"namespace,omitempty" yaml:"namespace,omitempty"`
	CommonLabels      types.FsSlice `json:"commonLabels,omitempty" yaml:"commonLabels,omitempty"`
	CommonAnnotations types.FsSlice `json:"commonAnnotations,omitempty" yaml:"commonAnnotations,omitempty"`
	NameReference     nbrSlice      `json:"nameReference,omitempty" yaml:"nameReference,omitempty"`
	VarReference      types.FsSlice `json:"varReference,omitempty" yaml:"varReference,omitempty"`
	Images            types.FsSlice `json:"images,omitempty" yaml:"images,omitempty"`
	Replicas          types.FsSlice `json:"replicas,omitempty" yaml:"replicas,omitempty"`
}

TransformerConfig holds the data needed to perform transformations.
