jenkins - 无法通过 docker 容器执行 ansible playbook

Question

我正在 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 的服务称为代理，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:

# 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 agent plabook 成功执行。但是，当我在 jenkins 容器中时，我在同一个命令调用中收到此错误。

编写文件:

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 容器中访问 docker 套接字。但是，由于某种原因，我无法访问我需要的 playbook 的 site.yml 文件，即使在容器之外该文件可用。

谁能帮我解决这个问题？

Answer 1

您对该卷安装点和路径的确定程度如何？

- 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 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 容器中添加等效项，以便您检查路径。我的猜测是工作空间不是你想的那样，你会想用以下方式运行 docker:

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

然后在容器内:

pushd /jenkins-worspace
