Types

type Component

type Component struct {
	Schemas     []string
	Definitions []string
}

func GenerateComponents

func GenerateComponents(ctx context.Context, manifest string, resource int, cfg Config) (*Component, error)

func GetFromHelm

func GetFromHelm(ctx context.Context, url string, resource int, cfg Config) (*Component, error)

func GetFromManifest

func GetFromManifest(ctx context.Context, url string, resource int, cfg Config) (*Component, error)

type Config

type Config struct {
	Name            string                 // Name of the service mesh,or k8 or meshery
	Type            string                 //Type of the workload like- Istio, TraefikMesh, Kuma, OSM, Linkerd,AppMesh,NginxMesh
	MeshVersion     string                 // For service meshes
	K8sVersion      string                 //For K8ss
	ModifyDefSchema func(*string, *string) //takes in definition and schema, does some manipulation on them and returns the new def and schema
	CrdFilter       CueCrdFilter
	ExtractCrds     func(manifest string) []string //takes in the manifest and returns a list of all the crds
}

all the data that is needed to get a certain value should be present in the config created by the adapter.

type CueCrdFilter

type CueCrdFilter struct {
	NameExtractor       CueFilter
	GroupExtractor      CueFilter
	VersionExtractor    CueFilter
	SpecExtractor       CueFilter
	IsJson              bool
	IdentifierExtractor CueFilter // identifiers are the values that uniquely identify a CRD (in most of the cases, it is the 'Name' field)
}

basically getter functions applicable for a single CRD can be interpreted as the things that are needed for generating a Component

func NewCueCrdFilter

func NewCueCrdFilter(ep ExtractorPaths, isJson bool) CueCrdFilter

type CueFilter

type CueFilter func(rootCRDCueVal cue.Value) (cue.Value, error)

takes in the parsed root cue value of the CRD as its input and returns the extracted value

type ExtractorPaths

type ExtractorPaths struct {
	NamePath    string
	GroupPath   string
	VersionPath string
	SpecPath    string
	IdPath      string
}
