Functions ¶
func DetectCandidateRevisionName ¶
DetectCandidateRevisionName attempts to deduce what revision could be considered a candidate.
func DetectStableRevisionName ¶
func DetectStableRevisionName(svc *run.Service) string
DetectStableRevisionName returns the stable revision of the Cloud Run service.
It first checks if there's a revision with the tag "stable". If such a revision does not exist, it checks for a revision with 100% of the traffic and considers it stable.
Types ¶
type Rollout ¶
type Rollout struct {
// contains filtered or unexported fields
}
Rollout is the rollout manager.
func New ¶
func New(ctx context.Context, metricsProvider metrics.Provider, svcRecord *ServiceRecord, strategy config.Strategy) *Rollout
New returns a new rollout manager.
func (*Rollout) UpdateService ¶
UpdateService changes the traffic configuration for the revisions and update the service.
If successful, it always returns an updated service object (with changes in the traffic and/or annotations) or an unchanged service object if no stable or candidate revision was found. If the traffic configuration changed, the second return value is set to true.
func (*Rollout) WithClient ¶
WithClient updates the client in the rollout instance.
type ServiceRecord ¶
ServiceRecord holds a service object and information about it.
