Functions

func ApplyResourceOverrides

func ConvertPodFailureToError(status v1.PodStatus) (code, message string)

func DecorateEnvVars

func DecorateEnvVars(ctx context.Context, envVars []v1.EnvVar, id pluginsCore.TaskExecutionID) []v1.EnvVar

func DemystifyPending

func DemystifyPending(status v1.PodStatus) (pluginsCore.PhaseInfo, error)

Important considerations. Pending Status in Pod could be for various reasons and sometimes could signal a problem Case I: Pending because the Image pull is failing and it is backing off

This could be transient. So we can actually rely on the failure reason.
The failure transitions from ErrImagePull -> ImagePullBackoff

Case II: Not enough resources are available. This is tricky. It could be that the total number of

resources requested is beyond the capability of the system. for this we will rely on configuration
and hence input gates. We should not allow bad requests that request for large number of resource through.
In the case it makes through, we will fail after timeout
