const OperatorConditionNameEnvVar = "OPERATOR_CONDITION_NAME"

OperatorConditionNameEnvVar - this Env var is set by OLM, so the Operator can discover it's OperatorCondition.

Variables

View Source 
var ErrNoNamespace = fmt.Errorf("namespace not found for current environment")

ErrNoNamespace indicates that a namespace could not be found for the current environment

View Source 
var ErrRunLocal = fmt.Errorf("operator run mode forced to local")

ErrRunLocal indicates that the operator is set to run in local mode (this error is returned by functions that only work on operators running in cluster mode)

View Source 
var ForceRunModeEnv = "OSDK_FORCE_RUN_MODE"

ForceRunModeEnv indicates if the operator should be forced to run in either local or cluster mode (currently only used for local mode)

GetWatchNamespace returns the namespace the operator should be watching for changes

func IsActuallyNil added in v1.7.0 

func IsActuallyNil(object interface{}) bool

func IsRunModeLocal() bool

func NewProcessingError added in v1.5.0 

func NewProcessingError(err error) error

NewProcessingError wraps an error if we want to actually stop processing by the error. unwrapping it will return the original error. unwrapping a regular error will return nil

err := ValidateManifestDir(...)
err == nil - OK: directory exists
err != nil && errors.Unwrap(err) == nil - directory does not exist, but that ok
err != nil && errors.Unwrap(err) != nil - actual error
