Question

我在docker容器内的jenkins上执行管道。此管道调用另一个执行ansible playbook的docker-compose文件。执行playbook的服务称为agent，定义如下：

Swift

这是它使用的图像：

agent:
  image: pjestrada/ansible
  links:
    - db
  environment:
    PROBE_HOST: "db"
    PROBE_PORT: "3306"
  command: ["probe.yml"]

我的本地机器是Ubuntu 16.04，当我运行FROM ubuntu:trusty MAINTAINER Pablo Estrada <pjestradac@gmail.com> # Prevent dpkg errors ENV TERM=x-term-256color RUN sed -i "s/http:\/\/archive./http:\/\/nz.archive./g" /etc/apt/sources.list #Install ansible RUN apt-get update -qy && \ apt-get install -qy software-properties-common && \ apt-add-repository -y ppa:ansible/ansible && \ apt-get update -qy && \ apt-get install -qy ansible # Copy baked in playbooks COPY ansible /ansible # Add voulme for Ansible Playbooks Volume /ansible WORKDIR /ansible RUN chmod +x / #Entrypoint ENTRYPOINT ["ansible-playbook"] CMD ["site.yml"]时，该电台成功执行。但是当我在jenkins容器里面时，我在同一个命令调用中得到了这个错误。

docker-compose up agent

这是我的jenkins容器的图像和撰写文件：

RUN /usr/local/bin/plugins.sh /usr/share/jenkins/plugins.txt

我放了一个卷，以便从我的jenkins容器访问docker socket。但是，由于某种原因，我无法访问我需要的play.yml文件，即使在容器外部文件可用。

有人可以帮我解决这个问题吗？

您如何确定该卷安装点和路径？

- jenkins_home:/var/jenkins_home

您是否尝试过通过echo进行调试？如果找不到site.yml，则最可能的原因是路径。您可以在作业上使用jenkins重播以快速迭代并修改jenkins代码的一部分。这样您就可以运行

sh "pwd; ls -la"

我建议在您的docker容器中添加等效项，以便您检查路径。我的猜测是工作空间不在您认为的位置，您将要使用以下命令运行docker：

-v${env.WORKSPACE}:jenkins-workspace

，然后在容器中：

pushd /jenkins-worspace

无法通过docker容器执行ansible playbook
