Functions

func GetExpectedTyphaScale added in v1.15.1 

func GetExpectedTyphaScale(nodes int) int

GetExpectedTyphaScale will return the number of Typhas needed for the number of nodes.

func HasWindowsNodes added in v1.32.0 

func HasWindowsNodes(c client.Client) (bool, error)

func MapExistsOrInitialize added in v1.27.17 

func MapExistsOrInitialize(m map[string]string) map[string]string

MapExistsOrInitialize returns the given map if non-nil or returns an empty map.

func MergeMaps added in v1.27.17 

func MergeMaps(current, desired map[string]string) map[string]string

MergeMaps merges current and desired maps. If both current and desired maps contain the same key, the desired map's value is used. MergeMaps does not copy operator-managed annotations from the current map.

func MergeOwnerReferences added in v1.29.2 

func MergeOwnerReferences(desired, current []metav1.OwnerReference) []metav1.OwnerReference

MergeOwnerReferences merges desired and current owner references, removing the duplicates. A UID identifies an owner, so desired's version of a reference wins over current's.

The result is sorted by UID, which keeps the merge convergent when more than one controller writes the object. Each caller passes its own reference in desired, so an order that followed the arguments would put a different reference first depending on who wrote last, and the two controllers would rewrite the object in turn for as long as both keep reconciling. Order carries no meaning to Kubernetes: owner references are a set, and the controller reference is identified by its Controller field rather than its position.

func MetricsEnabled added in v1.43.0 

func MetricsEnabled() bool

MetricsEnabled returns true when the operator metrics endpoint is enabled via METRICS_ENABLED=true.

func MetricsTLSEnabled added in v1.43.0 

func MetricsTLSEnabled() bool

MetricsTLSEnabled returns true when the operator metrics endpoint should use mTLS (METRICS_SCHEME=https).

func OperatorKey added in v1.40.0 

func OperatorKey() types.NamespacedName

func OperatorName added in v1.40.0 

func OperatorName() string

OperatorName returns the name of the operator deployment.

func OperatorNamespace added in v1.23.0 

func OperatorNamespace() string

OperatorNamespace returns the namespace the operator is running in. The value returned is based on the following priority (these are evaluated at startup): 

If the OPERATOR_NAMESPACE environment variable is non-empty then that is return.
If the file /var/run/secrets/kubernetes.io/serviceaccount/namespace is non-empty
then the contents is returned.
The default "tigera-operator" is returned.

func OperatorServiceAccount added in v1.24.2 

func OperatorServiceAccount() string

OperatorServiceAccount returns the ServiceAccount name the operator is running in. The value returned is based on the following priority (these are evaluated at startup): 

If the OPERATOR_SERVICEACCOUNT environment variable is non-empty then that is return.
If the file /var/run/secrets/kubernetes.io/serviceaccount/namespace is non-empty
then the contents is returned.
The default "tigera-operator" is returned.

func WindowsEnabled added in v1.32.0 

func WindowsEnabled(installation operatorv1.InstallationSpec) bool

WindowsEnabled returns true if the given Installation enables Windows, false otherwise.

Types

type VersionInfo added in v1.18.0 

type VersionInfo struct {
	Major int
	Minor int
}

VersionInfo contains information about the version of Kubernetes API the cluster is using Major and Minor fields map to the v<Major>.<Minor>+ part of the version string

func GetKubernetesVersion added in v1.18.0 

func GetKubernetesVersion(clientset kubernetes.Interface) (*VersionInfo, error)

func (*VersionInfo) ProvidesCertV1API added in v1.18.0 

func (v *VersionInfo) ProvidesCertV1API() bool

ProvidesCertV1API returns if k8s.io/api/certificates/v1 is supported given the current k8s version
