Question

我从昨天起就被封锁了，需要一些帮助。我尝试使用jenkins docker-plugin和docker-plugin-step从dockerfile构建docker镜像。

然而，当我尝试运行jenkins作业时，它给了我以下异常：

Docker Build

以下是dockerfile内容：

#Basic images for Gateway MS
FROM jdubois/jhipster-docker:Gateway_Jenkins_V1

#Fetch last Gateway MS version from gitlab and run it
RUN cd /home/jhipster/DockerJenkinsGateway && \
git pull origin master

# expose the working directory, the Tomcat port, the BrowserSync ports, the SSHD port, and run SSHD
VOLUME ["/jhipster"]
EXPOSE 8080 3000 3001 22
CMD    /usr/sbin/sshd -D

出错了什么？

Answer 1

另一个选择是使用Jenkins提供的shell作为构建步骤，并使用通常在该shell脚本中使用的命令行参数构建Docker镜像。

这就是我们在构建服务器上所做的事情，它为我们提供了对版本控制和推送到Dockerhub的图像/标记之类的细粒度控制。

如果您使用的是Jenkins 2.0或更高版本，那么Jenkins会为您提供构建管道作为代码的选项，您可以轻松地集成docker及其存储库。

转到 - ＆gt;新项目 - ＆gt;选择多分支管道选项，您将看到通过Jenkins连接到docker的选项。

如有更多详情，请告诉我。
