contexts

func IsContextCanceledErr ¶

func IsContextCanceledErr(err error) bool

IsContextCanceledErr checks whether the given error is caused by context cancellation.

func SetupSignalHandler ¶

func SetupSignalHandler() context.Context

SetupSignalHandler registers for SIGTERM and SIGINT. A context is returned which is canceled on one of these signals. If a second signal is caught, the program is terminated with exit code 1.

This code is a variant of the code from controller-runtime/pkg/signals, modified to use context.WithCancelCause so that the reason for cancellation can be propagated. This allows callers to distinguish between normal cancellation and cancellation due to termination signals.
