从fabric8中的git repo创建新应用程序时出现“无法连接到Docker守护程序”错误

Question

我在 openshift origin 3.3 上设置了 fabric8，fabric8 版本是“版本 0.4.121”。无论我在哪里尝试从 fabric8 中的 git repo 创建新应用程序，都会出现此错误：

[firstapp-testapp] Running shell script Executing shell script inside container [maven] of pod [kubernetes-085de53dd4cb4cfe990a727e68371b63-148fdbb6eea48] Executing command: sh -c echo $$ > '/home/jenkins/workspace/firstapp-testapp@tmp/durable-0d2c8f03/pid'; jsc=durable-f46e5a369ce24d99986ef5171a328446; JENKINS_SERVER_COOKIE=$jsc '/home/jenkins/workspace/firstapp-testapp@tmp/durable-0d2c8f03/script.sh'

为什么会出现这个错误？

Answer 1

由于内部 OpenShift 问题而发生错误。 请确保您的 OpenShift 实例已正确安装。

为此，您可以部署目录中的示例应用程序之一。 要手动解决此问题，您可以在 OpenShift 机器上执行以下语句

service docker restart

Answer 2

您是否尝试从容器中调用docker？您需要更改 SCC 才能做到这一点，但我不建议这样做。可能有更好的方法来完成同样的事情。
