Question

我有一个基于CentOS构建图像的Dockerfile（标记：centos6）：

FROM centos

RUN rpm -iUvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
RUN yum update -y
RUN yum install ansible -y

ADD ./ansible /home/root/ansible

RUN cd /home/root/ansible;ansible-playbook -v -i hosts site.yml

在Docker点击最后一行之前一切正常，然后我收到以下错误：

 [WARNING]: The version of gmp you have installed has a known issue regarding
timing vulnerabilities when used with pycrypto. If possible, you should update
it (ie. yum update gmp).

Stderr from the command:

    package epel-release-6-8.noarch is already installed

我认为错误的原因是gmp包不是最新的。 GitHub上有一个相关问题：https://github.com/ansible/ansible/issues/6941

但目前似乎没有任何解决方案...... 有任何想法吗？提前谢谢！

我的site.yml剧本：

- hosts: all

  pre_tasks:
    - shell: echo 'hello'

Answer 1

确保您要添加到site.yml的目录中存在hosts和/home/root/ansible个文件。

旁注，您可以使用WORKDIR：

来简化Dockerfile

WORKDIR /home/root/ansible
RUN ansible-playbook -v -i hosts site.yml

Answer 2

PyCrypto依赖于GMP，警告告诉你在更新pycrypto后更新它（在你的ansible主机上）。

yum -y update gmp pip install --upgrade PyCrypto

由于Centos6上的GMP包版本导致的Ansible错误
