Question

我只是想告诉Ansible在我的OS X机器上构建一个docker镜像，这是我得到的错误：

$ ansible-playbook main.yml

PLAY [localhost] **************************************************************

GATHERING FACTS ***************************************************************
ok: [localhost]

TASK: [Build docker image from dockerfiles] ***********************************
failed: [localhost] => {"changed": false, "failed": true}
msg: ConnectionError(ProtocolError('Connection aborted.', error(2, 'No such file or directory')),)

FATAL: all hosts have already failed -- aborting

PLAY RECAP ********************************************************************
           to retry, use: --limit @/Users/ronny/main.retry

localhost                  : ok=1    changed=0    unreachable=0    failed=1

这是我正在使用的main.yml文件：

---
- hosts: localhost
  connection: local

  tasks:
        - name: Build docker image from dockerfiles
          docker_image:
            name: testimage
            path: test
            state: build

我的Dockerfile：

# Build an example Docker container image. 
FROM busybox 
MAINTAINER Jeff Geerling <geerlingguy@mac.com>

# Run a command when the container starts. 
CMD ["/bin/true”]”

我的泊坞窗文件位于 cookbook / test / Dockerfile

中

main.yml文件位于 cookbook / main.yml

我在OS X上运行它。

我完全迷失了，任何帮助都会非常感激。

为了回应我使用-vvvv的Nathanials请求，我收到以下错误：

为了响应上述错误，我尝试提供了Dockerfile所在的构建目录的完整路径

然后我得到了：

编辑＃2

好的，我尝试过不同的事情。而不是建立一个图像，我试图简单地开始一个。在lib / python2.7 / site-packages / ansible / modules / core / cloud / docker / docker.py中挖掘之后我注意到在第558行的DockerManager.init类中，他们设置了一些环境变量：

env_host = os.getenv('DOCKER_HOST')
env_docker_verify = os.getenv('DOCKER_TLS_VERIFY')
env_cert_path = os.getenv('DOCKER_CERT_PATH')
env_docker_hostname = os.getenv('DOCKER_TLS_HOSTNAME')

所以我将这些值吐出到日志文件中，并且看，没有一个被设置。

然后我直接在main.yml中设置它们：

- name: start container
      docker:
        name: mydata
        image: busybox
        state: present
      environment:
        DOCKER_HOST: tcp://192.168.59.103:2376
        DOCKER_TLS_VERIFY: 1
        DOCKER_CERT_PATH: /Users/ronny/.boot2docker/certs/boot2docker-vm
        DOCKER_TLS_HOSTNAME: boot2docker

我能够成功启动容器！

但是，这个方法不适用于我的初始问题，即构建一个泊坞窗图像。

在docker_image.py中进一步挖掘我注意到它在第188行周围发生故障（我说＆＃34;周围＆＃34;因为我有记录中断所以我不知道确切的行）它在哪里以下代码：

   images = self.client.images()

更多挖掘，我看到self.client正在'unix://var/run/docker.sock'

检查docker_url

但是在link处，我发现OS X上不存在/var/run/docker.sock，而是一个回复说

/var/run/docker.sock不会出现在您的OSX文件系统上 - Docker   守护进程在boot2docker VM中运行 - 那就是   unix socket是。

该串行文件也与docker socket无关。

oyu需要与DOCKER_HOST环境中指定的TCP套接字进行通信。

现在我尝试将docker_url设置为DOCKER_HOST URL，因为此模块的说明如下：

docker_url：描述： - 要发出命令的docker主机的URL 必需：false 默认值：unix：//var/run/docker.sock 别名：[]

但是当我将它设置为DOCKER_HOST地址时，我收到了一个错误。

这是main.yml

   - name: Build docker image from dockerfiles 
          docker_image:
            name: testimage 
#            path: test
            path: /Users/ronny/projects/dockers/tutorial/ansibledocker/test
            state: build
            docker_url: 192.168.59.103:2376

这是错误：

failed: [localhost] => {"changed": false, "failed": true}
msg: ConnectionError(ProtocolError('Connection aborted.', BadStatusLine('\x15\x03\x01\x00\x02\x02\n',)),)

localhost                  : ok=3    changed=0    unreachable=0    failed=1

有什么想法吗？

Answer 1

作为一种解决方法，您可以使用代理“socat-container”将您的请求从tcp地址路由到unix套接字。看一下这个page。 boot2docker上的端口2376只适用于ipv6而不是ipv4（我发现没有办法改变这个，我没有深入研究这个问题而且不喜欢改变boot2docker VM的想法）。我还在VirtualBox中为我的localhost（ansible inventory localhost）添加了NAT转换

小心使用ansible和docker-py

你需要：

ansible 1.9.2
docker_api_version：1.18

适合我。

Answer 2

如果您想使用Ansible构建docker镜像，我建议您查看Ansible Container，它是Ansible的一个开源项目，专注于构建docker镜像。

Ansible Container使您可以使用现有/自己的Ansible角色来构建docker镜像。

Answer 3

您的第一个配置几乎是“正常”，需要更改两件事

tasks: ...
  path: ./test
  state: present

在你的情况下，ansible的根目录是你的main.yml文件所在的位置。

cookbook/
├── main.yml
└── test
    └── Dockerfile

所以main.yml的内容保持不变

---
- hosts: localhost
  connection: local

  tasks:
  - name: Build docker image from dockerfiles
    docker_image:
      name: testimage
      path: ./test
      state: present

状态需要现在符合doc

Answer 4

如果在使用docker for mac（beta）时出现此错误，您可能忘记在远程服务器上安装docker。
