Functions

func Diff added in v0.9.0 

func Diff(a, b cue.Value)

Diff prints a line-by-line diff between two Cue values.

func Extract added in v0.9.0 

func Extract(v cue.Value, s interface{}) error

Extract pulls values out of CUE and encodes them into a Go struct with JSON tags.

func ExtractAndTypeK8sManifestObjects added in v0.9.0 

func ExtractAndTypeK8sManifestObjects(manifests []json.RawMessage) (manifestObjects []client.Object)

ExtractAndTypeK8sManifestObjects takes a list of raw k8s manifest objects, determines their types, and unmarshals each one into an object of the correct type.

func FromStrings added in v0.9.0 

func FromStrings(ss ...string) cue.Value

FromStrings creates a cue.Value from string arguments.

func FromStruct added in v0.9.0 

func FromStruct(name string, s interface{}) (cue.Value, error)

FromStruct creates a nested cue.Value from a Go struct. The new cue.Value will have a single field from name, which will contain the struct.

func IdentifyGMConfigObjects added in v0.9.0 

func IdentifyGMConfigObjects(rawObjects []json.RawMessage) (kinds []string)

IdentifyGMConfigObjects takes a list of raw objects and identifies them as particular GreyMatter config object types

func Interfaces added in v0.9.0 

func Interfaces(kvs map[string]interface{}) cue.Value

StringSlices creates a cue.Value from fields defined in a map[string]interface{}. Supported Cue builtin types are bool, number, and struct.

func LogError added in v0.9.0 

func LogError(logger logr.Logger, err error)

LogError logs errors that may or may not contain a list of cue/errors.Error. If the error provided is not a cue/errors.Error, a plain error is logged.

func StringSlices added in v0.9.0 

func StringSlices(kvs map[string][]string) cue.Value

StringSlices creates a cue.Value from fields defined in a map[string][]string.

func Strings added in v0.9.0 

func Strings(kvs map[string]string) cue.Value

Strings creates a cue.Value from fields defined in a map[string]string.

Types

type Config added in v0.9.0 

type Config struct {
	// Flags
	Spire                bool `json:"spire"`
	AutoApplyMesh        bool `json:"auto_apply_mesh"`
	GenerateWebhookCerts bool `json:"generate_webhook_certs"`

	// Values
	ClusterIngressName string `json:"cluster_ingress_name"`
}

Config represents the `config` struct from the operator CUE in inputs.cue

type Defaults added in v0.9.0 

type Defaults struct {
	SidecarList []string `json:"sidecar_list"`
}

type OperatorCUE added in v0.9.0 

type OperatorCUE struct {
	// cue.Value for all of k8s/outputs containing k8s manifest objects
	K8s cue.Value

	// cue.Value for all of gm/outputs containing Grey Matter config objects
	GM cue.Value
}

OperatorCUE holds the two top-level cue.Values that configure the operator, according to the major split between K8s and GM configuration

func LoadAll added in v0.9.0 

func LoadAll(cuemoduleRoot string) (*OperatorCUE, *v1alpha1.Mesh, error)

LoadAll loads the provided CUE for configuring the operator into an OperatorCUE and a Mesh

func (*OperatorCUE) ExtractConfig added in v0.9.0 

func (operatorCUE *OperatorCUE) ExtractConfig() (Config, Defaults)

ExtractConfig pulls the values from the CUE into the Config struct in Go for use in various places in the operator

func (*OperatorCUE) ExtractCoreK8sManifests added in v0.9.0 

func (operatorCUE *OperatorCUE) ExtractCoreK8sManifests() (manifestObjects []client.Object, err error)

ExtractCoreK8sManifests extracts the K8s manifests for a mesh from the top-level array in the k8s/outputs/EXTRACTME.cue

func (*OperatorCUE) ExtractCoreMeshConfigs added in v0.9.0 

func (operatorCUE *OperatorCUE) ExtractCoreMeshConfigs() (meshConfigs []json.RawMessage, kinds []string, err error)

ExtractCoreMeshConfigs extracts the GM config objects for a mesh from the top-level array in the gm/outputs/EXTRACTME.cue

func (*OperatorCUE) ExtractRedisListener added in v0.9.0 

func (operatorCUE *OperatorCUE) ExtractRedisListener() (configObject json.RawMessage, err error)

ExtractRedisListener returns the listener object for the redis listener with spire subjects set. Assumes unification has already happened to insert the correct sidecarList

func (*OperatorCUE) TempGMValueUnifiedWithDefaults added in v0.9.0 

func (operatorCUE *OperatorCUE) TempGMValueUnifiedWithDefaults(defaults Defaults) (OperatorCUE, error)

func (*OperatorCUE) UnifyAndExtractSidecar added in v0.9.0 

func (operatorCUE *OperatorCUE) UnifyAndExtractSidecar(clusterLabel string) (container corev1.Container, volumes []corev1.Volume, err error)

UnifyAndExtractSidecar unifies the cluster meant for a deployment with the CUE for a to-be-injected sidecar, and extracts the K8s manifest components to be injected

func (*OperatorCUE) UnifyAndExtractSidecarConfig added in v0.9.0 

func (operatorCUE *OperatorCUE) UnifyAndExtractSidecarConfig(name string, port int) (configObjects []json.RawMessage, kinds []string, err error)

UnifyAndExtractSidecarConfig unifies a name and port with the Grey Matter sidecar configuration CUE for injected sidecars, and returns those configuration objects, along with their kinds (e.g., listener, cluster, etc.) It also extracts the special redis_listener object. NB: This method expects that the embedded Mesh in the CUE has already been updated with a status.sidecar_list for that redis_listener

func (*OperatorCUE) UnifyWithMesh added in v0.9.0 

func (operatorCUE *OperatorCUE) UnifyWithMesh(mesh *v1alpha1.Mesh) error

UnifyWithMesh unifies the operatorCUE with a Mesh CR to fill in values
