Ibm cloud 简单容器工具链-部署失败：超过最大重试次数

我正在尝试运行由简单容器工具链示例创建的部署管道。部署日志的输出为：

...

To send notifications, set SLACK_WEBHOOK_PATH or HIP_CHAT_TOKEN in the environment

Finished: FAILED

如果导航到Bluemix中的容器仪表板，我会看到以下错误日志：

Group failed
Resource CREATE failed: ResourceInError: resources.asg.resources.i2jghszuv3br.resources.server: Went to status ERROR due to "Message: Exceeded maximum number of retries.

Last exception: [u'Traceback (most recent call last): \n', u' File "/opt/bbc/openstack-12.1.90/nova/local/lib/python2.7/site-packages, Code: 500"
