我正在Jenkins内的Docker容器中执行一个管道。这个管道调用另一个docker-compose文件,该文件执行一个ansible playbook。执行playbook的服务称为代理,并定义如下:
agent:
image: pjestrada/ansible
links:
- db
environment:
PROBE_HOST: "db"
PROBE_PORT: "3306"
command: ["probe.yml"]
这是它使用的图片:

# 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
时,playbook可以成功执行。但是当我在Jenkins容器内部执行相同的命令调用时,出现了这个错误。

我为了让我的Jenkins容器能够访问Docker套接字,已经设置好了卷。但是,由于某些原因,我无法访问playbook所需的site.yml文件,尽管在容器外该文件可用。
有人能帮助我解决这个问题吗?
