Functions

func APIServerNamespace

func APIServerNamespace(v operatorv1.ProductVariant) string

APIServerNamespace returns the namespace to use for the API server component.

func AnnotationHash

func AnnotationHash(i interface{}) string

AnnotationHash is to generate a hash that can be included in a Deployment or DaemonSet to trigger a restart/rolling update when a ConfigMap or Secret is updated.

func DefaultOperatorCASignerName

func DefaultOperatorCASignerName() string

func GetResourceRequirements

func GetResourceRequirements(i *operatorv1.InstallationSpec, name operatorv1.ComponentName) corev1.ResourceRequirements

GetResourceRequirements retrieves the component ResourcesRequirements from the installation. If it doesn't exist, it returns an empty ResourceRequirements struct.

func SecretsAnnotationHash

func SecretsAnnotationHash(secrets ...*corev1.Secret) string

SecretsAnnotationHash generates a hash based off of the data in each secrets Data field that can be used by Deployments or DaemonSets to trigger a restart/rolling update based on changes to one of more secrets data.

Types

type OSType

type OSType string

This type helps ensure that we only use defined os types

const (
	DefaultCertificateDuration = 825 * 24 * time.Hour

	OSTypeAny     OSType = "any"
	OSTypeLinux   OSType = "linux"
	OSTypeWindows OSType = "windows"

	// The name prefix used for the CA issuer, which is used for self-signed
	// certificates issued for operator-managed certificates.
	// NOTE: Do not change this field since we use this value to identify
	// certificates managed by this operator.
	TigeraOperatorCAIssuerPrefix = "tigera-operator-signer"
)
