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

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 docker 文件位于 cookbook/test/Dockerfile

而main.yml文件位于cookbook/main.yml

我在 OS X 上运行它。

此时我完全迷失了，非常感谢任何帮助。

编辑:

为了响应我使用 -vvvv 的 Nathanial 请求，我收到以下错误:

针对上述错误，我尝试给出Dockerfile所在构建目录的完整路径

编辑#2

好的，我尝试做一些不同的事情。我没有构建图像，而是尝试简单地启动一个图像。在 lib/python2.7/site-packages/ansible/modules/core/cloud/docker/docker.py 中挖掘后，我注意到在第 558 行附近的类 DockerManager.init 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一个日志文件中，你瞧，它们都没有被设置。

然后当我直接在 main.yml 中设置它们时:

- 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

我能够成功启动一个容器!

但是，这种方法不适用于我最初的问题，即构建 docker 镜像。

在 docker_image.py 中进一步挖掘，我注意到它在第 188 行附近发生故障(我说“周围”是因为我有日志记录中断，所以我不知道确切的行)，其中包含以下代码:

   images = self.client.images()

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

但在此 link我看到/var/run/docker.sock 在 OS X 上不存在，而是一个回复说

/var/run/docker.sock will not be on your OSX filesystem - the Docker daemon is running inside the boot2docker VM - and that's where the unix socket is.

That serial file is also not related to the docker socket.

oyu need to talk to the TCP socket specified in the DOCKER_HOST env.

现在我尝试将 docker_url 设置为 DOCKER_HOST URL，正如该模块的描述所述:

docker_url: description: - URL of docker host to issue commands to required: false default: unix://var/run/docker.sock aliases: []

但是当我将它设置为 DOCKER_HOST 地址时，我得到了一个错误。

这里是 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',)),)

FATAL: all hosts have already failed -- aborting

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

有什么想法吗？

最佳答案

你的第一个配置几乎“ok”了，有两件事需要改变

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

在您的情况下，ansible 的根目录是您的 main.yml 文件所在的位置。

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

所以main.yml的内容就这样了

---
- hosts: localhost
  connection: local

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

状态需要存在符合doc
