Question

嗨，

我试图在Jenkins管道中构建和运行Docker-Container，然后对容器中已部署的Web应用程序进行一些测试。问题是我的容器只存活了几秒钟，然后死于退出代码0。已经尝试在具有和不具有Docker Groovy插件的情况下以交互模式运行它。

我的管道代码如下：

stage("Docker Build&Run") {
    steps {
        script {
            def tag = "shop:${env.BUILD_ID}"
            docker.build(tag)
            //sh "docker run -d -p 8443:443/tcp ${tag}" Tried both
            docker.image(tag).run('-p 8443:443/tcp')
        }
    }
}
stage("Dummy Dynamic Analysis") {
    steps {
        echo "Dummy Dynamic Analysis" //to be integrated
        sleep 120 //application should be available here since it has to be theire for  testing as well
    }
}

事件看起来像这样。几秒钟后被摧毁：

如何部署容器并使它无限期运行直到停止运行，或者在jenkins整个运行期间至少保持运行？

预先感谢大家。问候

因此我的docker文件看起来像这样：

FROM ubuntu:14.04

RUN echo "#!/bin/sh\nexit 0" > /usr/sbin/policy-rc.d

ADD ./provision.sh /tmp/provision.sh
RUN /bin/bash /tmp/provision.sh

ENTRYPOINT service apache2 start && service mysql start && /bin/bash

EXPOSE 443

我刚刚意识到读了这篇文章：How to keep Docker container running after starting services?，当我的入口点调用完成时，docker容器将退出，并且只要我的服务还活着，它就不会活着。我认为这将会发生。我现在切换到建议的解决方案，该解决方案在有监督的条件下运行，并且运行良好。谢谢大家。

新的Dockerfile：

FROM ubuntu:14.04

RUN echo "#!/bin/sh\nexit 0" > /usr/sbin/policy-rc.d

RUN apt-get update && apt-get install supervisor -y

ADD ./provision.sh /tmp/provision.sh
ADD ./supervisord.conf /etc/supervisor/conf.d/supervisord.conf
RUN /bin/bash /tmp/provision.sh

ENTRYPOINT ["/usr/bin/supervisord", "-n"]

EXPOSE 443

Conf主管：

[supervisord]
nodaemon=true

[program:mysql]
command=/usr/bin/pidproxy /var/run/mysqld/mysqld.pid /usr/sbin/mysqld
autorestart=true

[program:apache]
command=/usr/sbin/apache2ctl -DFOREGROUND
autorestart=true

几秒钟后，Jenkins Pipeline中的Docker容器死亡
