Ansible docker_container'请求URL中没有主机',docker pull工作正常

Question

我正在尝试使用Ansible playbooks在AWS上配置我的基础架构.我有实例,并且能够提供docker-engine,docker-py等等,我发誓,昨天这个工作正常,我没有更改代码.

我的剧本的相关部分是:

- name: Ensure AWS CLI is available
  pip:
    name: awscli
    state: present
  when: aws_deploy
- block:
  - name: Add .boto file with AWS credentials.
    copy:
      content: "{{ boto_file }}"
      dest: ~/.boto
    when: aws_deploy
  - name: Log in to docker registry.
    shell: "$(aws ecr get-login --region us-east-1)"
    when: aws_deploy
  - name: Remove .boto file with AWS credentials.
    file:
      path: ~/.boto
      state: absent
    when: aws_deploy
  - name: Create docker network
    docker_network:
      name: my-net
  - name: Start Container
    docker_container:
      name: example
      image: "{{ docker_registry }}/example"
      pull: true
      restart: true
      network_mode: host
      volumes:
        - /etc/localtime:/etc/localtime:ro
        - /etc/timezone:/etc/timezone

我的目标{{ docker_registry }}是,my-acct-id.dkr.ecr.us-east-1.amazonaws.com我得到的结果是:

"msg": "Error pulling my-acct-id.dkr.ecr.us-east-1.amazonaws.com/example - code: None message: Get http://: http: no Host in request URL"

然而,正如前面提到的,昨晚这种方式正常.从那时起,我做了一些VPC /子网更改,但我能够ssh到实例,并运行docker pull my-acct-id.dkr.ecr.us-east-1.amazonaws.com/example没有问题.

谷歌搜索引导我不远,因为我似乎无法找到其他人有同样的错误.我想知道改变了什么,以及如何解决它!谢谢!

编辑:版本:

• ansible - 2.2.0.0
• docker - 1.12.3 6b644ec
• docker-py - 1.10.6

我有同样的问题。将该主机上的 docker-compose pip 映像从 1.9.0 降级到 1.8.1 解决了该问题。

- name: Install docker-compose
  pip: name=docker-compose version=1.8.1

根据此线程： https: //github.com/ansible/ansible-modules-core/issues/5775，真正的罪魁祸首是请求。这修复了它：

  - name: fix requests
    pip: name=requests version=2.12.1 state=forcereinstall
