Я создаю конвейер CD с использованием Jenkins на движке Google Kubernetes и сталкиваюсь с проблемами при первой сборке. Как показано в выводе ниже, конвейерные этапы пропускаются «из-за более ранних сбоев», которые я не могу идентифицировать.

Я очень новичок в Дженкинсе, поэтому был бы признателен за любую помощь. Я также вставил файл Jenkins ниже.

Очевидно, что в нижней части журнала находится сообщение:

ERROR: Node is not a Kubernetes node:

Конвейеру не удается запустить агент kubernetes, потому что мастер (согласно журналу: «Выполняется на Jenkins в /var/jenkins_home/workspace/sample-app_canary») отсутствует в кластере kubernetes, который был настроен в разделе «Управление облаками» в Jenkins.
