Functions

func AddSpinnakerAnnotations 

func AddSpinnakerAnnotations(u *unstructured.Unstructured, application string) error

AddSpinnakerAnnotations adds Spinnaker-defined annotations to a given unstructured resource.

func AddSpinnakerLabels 

func AddSpinnakerLabels(u *unstructured.Unstructured, application string) error

AddSpinnakerLabels labels a given unstructured Kubernetes resource with Spinnaker defined labels.

func AddSpinnakerVersionAnnotations 

func AddSpinnakerVersionAnnotations(u *unstructured.Unstructured, version SpinnakerVersion) error

AddSpinnakerVersionAnnotations adds the following annotations: `artifact.spinnaker.io/version` `moniker.spinnaker.io/sequence` to the manifest to identify the version number of that resource.

func AddSpinnakerVersionLabels 

func AddSpinnakerVersionLabels(u *unstructured.Unstructured, version SpinnakerVersion) error

AddSpinnakerVersionLabels adds the `moniker.spinnaker.io/sequence` label to the manifest to identify the version number of that resource.

func AnnotateTemplate 

func AnnotateTemplate(u *unstructured.Unstructured, key, value string) error

AnnotateTemplate annotates the nested string map located at .spec.template.metadata.annotations.

func BindArtifacts 

func BindArtifacts(u *unstructured.Unstructured,
	artifacts []clouddriver.Artifact)

BindArtifacts takes in an unstructured Kubernetes object and a slice of artifacts then binds these artifacts to any applicable JSON path for the given artifact.

For example, take the following manifest that references a configMap with name 'replace-me':

apiVersion: v1 kind: Pod metadata: 

name: dapi-test-pod

spec: 

containers:
  - name: test-container
    image: k8s.gcr.io/busybox
    volumeMounts:
    - name: my-volume
      mountPath: /etc/config
volumes:
  - name: my-volume
    configMap:
      # Provide the name of the ConfigMap containing the files you want
      # to add to the container
      name: replace-me
restartPolicy: Never

Now let's say we pass in the following Clouddriver Artifact: 

{
  "name": "replace-me",
  "reference": "my-config-map-v000"
}

This would result in the JSON path '.spec.volumes[0].configMap.name' changing from 'replace-me' to 'my-config-map-v000'.

The source code for these Replacers can be found here: https://github.com/spinnaker/clouddriver/blob/4d4e01084ac5259792020e419b1af7686ab38019/clouddriver-kubernetes/src/main/java/com/netflix/spinnaker/clouddriver/kubernetes/artifact/Replacer.java#L150

func Cluster added in v0.20.0 

func Cluster(kind, name string) string

Generate the cluster that a kind is a part of. A Kubernetes cluster is of kind deployment, statefulSet, replicaSet, ingress, service, and daemonSet so only generate a cluster for these kinds.

func DefaultLabelSelector added in v0.19.0 

func DefaultLabelSelector() string

DefaultLabelSelector returns the label selector `app.kubernetes.io/managed-by in (spinnaker,spinnaker-operator)`, which allows us to list all resources with a label selector managed by Spinnaker or Spinnaker Operator.

func FilterOnAnnotation(items []unstructured.Unstructured,
	annotationKey, annotationValue string) []unstructured.Unstructured

FilterOnAnnotations takes a slice of unstructured and returns the filtered slice based on a given annotation key and value.

func FilterOnLabelExists added in v0.19.0 

func FilterOnLabelExists(items []unstructured.Unstructured,
	label string) []unstructured.Unstructured

FilterOnLabelExists takes a slice of unstructured and returns a filtered slice where a given label exists in each of the unstructured objects.

func GetCurrentVersion 

func GetCurrentVersion(ul *unstructured.UnstructuredList, kind, name string) string

GetCurrentVersion returns the latest "Spinnaker version" from an unstructured list of Kubernetes resources.

func GetStatus 

func GetStatus(kind string, m map[string]interface{}) manifest.Status

Status definitions of kinds can be found at https://github.com/spinnaker/clouddriver/tree/master/clouddriver-kubernetes/src/main/java/com/netflix/spinnaker/clouddriver/kubernetes/op/handler

func IsVersioned 

func IsVersioned(u unstructured.Unstructured) bool

IsVersioned returns true is a given Kubernetes unstructured resource is "versioned". A resource is version if its annotation `strategy.spinnaker.io/versioned` is set to "true" or if it is of kind Pod, ReplicaSet, ConfigMap, or Secret.

See https://spinnaker.io/reference/providers/kubernetes-v2/#workloads for more info.

func LoadBalancers added in v0.20.0 

func LoadBalancers(u unstructured.Unstructured) ([]string, error)

LoadBalancers returns a slice of load balancers from the annotation `traffic.spinnaker.io/load-balancers`. It errors if this annotation is not a string slice format like '["service my-service", "service my-service2"]'.

See https://spinnaker.io/docs/reference/providers/kubernetes-v2/#traffic for more info.

func MaxVersionHistory 

func MaxVersionHistory(u unstructured.Unstructured) (maxVersionHistory int, err error)

MaxVersionHistory returns the value as an int of the annotation `strategy.spinnaker.io/max-version-history` of the given Kubernetes unstructured resource, or 0 if annotation is not present.

See https://spinnaker.io/docs/reference/providers/kubernetes-v2/#strategy for more info.

func NameWithoutVersion added in v0.20.0 

func NameWithoutVersion(name string) string

NameWithVersion removes the Spinnaker version (trailing '-v###) from the name.

func NewRequirement 

func NewRequirement(op string, key string, values []string) (*labels.Requirement, error)

func Recreate 

func Recreate(u unstructured.Unstructured) bool

Recreate returns true if the given Kubernetes unstructured resource has the annotation `strategy.spinnaker.io/recreate` set to "true".

See https://spinnaker.io/docs/reference/providers/kubernetes-v2/#strategy for more info.

func Replace 

func Replace(u unstructured.Unstructured) bool

Replace returns true if the given Kubernetes unstructured resource has the annotation `strategy.spinnaker.io/replace` set to "true".

See https://spinnaker.io/docs/reference/providers/kubernetes-v2/#strategy for more info.

func SetDefaultNamespaceIfScopedAndNoneSet 

func SetDefaultNamespaceIfScopedAndNoneSet(u *unstructured.Unstructured, helper *resource.Helper)

func SetNamespaceIfScoped 

func SetNamespaceIfScoped(namespace string, u *unstructured.Unstructured, helper *resource.Helper)

func SortManifests 

func SortManifests(manifests []unstructured.Unstructured) []unstructured.Unstructured

SortManifests takes in a list of manifests and sorts them by the priority of their kind. The kind's priorities are defined above in the var 'priorities'. Lower numbered priorities should be deployed first.

func SpinnakerMonikerApplication added in v0.20.0 

func SpinnakerMonikerApplication(u unstructured.Unstructured) string

SpinnakerMonikerApplication returns the value the annotation `moniker.spinnaker.io/application` of the given Kubernetes unstructured resource, or an empty string if not present.

func ToUnstructured 

func ToUnstructured(manifest map[string]interface{}) (unstructured.Unstructured, error)

ToUnstructured converts a map[string]interface{} to a kubernetes unstructured.Unstructured object. An unstructured's "Object" field is technically just a map[string]interface{}, so we could do the following:

return unstructured.Unstructured{ Object: manifest }

and not have this function return an error, but we miss out on some validation that happens during `kubectl`, such as when you attempt to apply a bad manifest, like something without "kind" specified. Example:

$ k apply -f bad.yaml --validate=false error: unable to decode "bad.yaml": Object 'Kind' is missing in '{}'

If we decide to not cycle through the encoding/decoding process, these errors will be deferred to when the manifest gets applied, and will fail with some error like

error applying manifest (kind: , apiVersion: v1, name: bad-gke): no matches for kind "" in version "apps/v1"

For now, we are not deferring the error.

func UseSourceCapacity 

func UseSourceCapacity(u unstructured.Unstructured) bool

UseSourceCapacity returns true is a given Kubernetes unstructured resource has the annotation `strategy.spinnaker.io/use-source-capacity` set to "true" and it is of kind Deployment, ReplicaSet, or StatefulSet.

See https://spinnaker.io/docs/reference/providers/kubernetes-v2/#strategy for more info.
