Functions

func CheckForMultipleWatchtowerInstances

func CheckForMultipleWatchtowerInstances(client container.Client, cleanup bool, scope string) error

CheckForMultipleWatchtowerInstances will ensure that there are not multiple instances of the watchtower running simultaneously. If multiple watchtower containers are detected, this function will stop and remove all but the most recently started container. This behaviour can be bypassed if a scope UID is defined.

func Update

func Update(client container.Client, params types.UpdateParams) (*metrics2.Metric, error)

Update looks at the running Docker containers to see if any of the images used to start those containers have been updated. If a change is detected in any of the images, the associated containers are stopped and restarted with the new image.
