原作者: [db:作者] 来自: [db:来源] 收藏 邀请

本文整理汇总了Golang中github.com/openshift/origin/pkg/deploy/util.IsFailedDeployment函数的典型用法代码示例。如果您正苦于以下问题:Golang IsFailedDeployment函数的具体用法?Golang IsFailedDeployment怎么用?Golang IsFailedDeployment使用的例子?那么恭喜您, 这里精选的函数代码示例或许可以为您提供帮助。



在下文中一共展示了IsFailedDeployment函数的5个代码示例,这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞,您的评价将有助于我们的系统推荐出更棒的Golang代码示例。

示例1: retry

// retry resets the status of the latest deployment to New, which will cause
// the deployment to be retried. An error is returned if the deployment is not
// currently in a failed state.
func (o DeployOptions) retry(config *deployapi.DeploymentConfig) error {
	if config.Spec.Paused {
		return fmt.Errorf("cannot retry a paused deployment config")
	}

		return fmt.Errorf("no deployments found for %s/%s", config.Namespace, config.Name)
	}
	// TODO: This implies that deploymentconfig.status.latestVersion is always synced. Currently,
	// that's the case because clients (oc, trigger controllers) are updating the status directly.
	// Clients should be acting either on spec or on annotations and status updates should be a
	// responsibility of the main controller. We need to start by unplugging this assumption from
	// our client tools.
	deploymentName := deployutil.LatestDeploymentNameForConfig(config)
	deployment, err := o.kubeClient.ReplicationControllers(config.Namespace).Get(deploymentName)
	if err != nil {

	pods, err := o.kubeClient.Pods(config.Namespace).List(kapi.ListOptions{LabelSelector: deployutil.DeployerPodSelector(deploymentName)})
	if err != nil {
