无法通过docker容器执行ansible playbook

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:

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

这是它使用的图像:

FROM ubuntu:trusty

# 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"]

我的本地机器是Ubuntu 16.04,当我运行docker-compose up agentplabook时成功执行.但是当我在jenkins容器里面时我在同一个命令调用中得到这个错误.

这是我的jenkins容器的图像和撰写文件:

撰写文件:

version: '2'

volumes:
  jenkins_home:
    external: true

services:
  jenkins:
    build:
      context: .
      args:
        DOCKER_GID: ${DOCKER_GID}
        DOCKER_ENGINE: ${DOCKER_ENGINE}
        DOCKER_COMPOSE: ${DOCKER_COMPOSE}
    volumes:
      - jenkins_home:/var/jenkins_home
      - /var/run/docker.sock:/var/run/docker.sock
    ports:
      - "8080:8080"

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,即使在容器外部文件可用,我也无法访问我需要的play.yml文件.

任何人都可以帮我解决这个问题吗？

Answer 1

您对该卷安装点和路径有多确定？

- jenkins_home:/var/jenkins_home

您尝试过通过 echo 进行调试吗？如果找不到 site.yml，则最有可能的原因是路径。您可以在作业上使用 jenkins replay 来快速迭代并修改部分 jenkins 代码。这会让你运行类似的东西

sh "pwd; ls -la"

我建议在您的 docker 容器中添加等效内容，以便您可以检查路径。我的猜测是，工作区不在您想象的位置，您需要使用以下命令运行 docker：

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

然后在容器内：

pushd /jenkins-worspace
