在OS X上使用Ansible运行docker任务时出现问题
在OS X上使用Ansible运行docker任务时出现问题
提问于 2015-05-31 07:20:18
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 ***************************************************************

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:

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中
而cookbook/main.yml中的main.yml文件
我在OS X上运行这个程序。
我在这一点上完全迷失了，任何帮助都将非常感谢。

在响应Nathanial要求我使用-vvvv的请求时，我得到了以下错误：
(这是将路径设置为子目录“test”的位置)

好吧，我试着做一些不同的事情。我没有建立一个图像，而是尝试简单地启动一个图像。在深入研究了lib/python2.7/site-packages/ansible/modules/core/cloud/docker/docker.py之后，我注意到在DockerManager.init类的558行附近，他们设置了几个环境变量：
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')因此，我将这些值输出到一个日志文件中，您看，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我成功地启动了一个容器！
然而，这种方法不适用于我最初的问题，即构建docker映像。
进一步深入研究docker_image.py，我注意到它在第188行附近崩溃(我说" around“是因为我有日志中断，所以我不知道确切的行)，它有以下代码：
images = self.client.images()更深入的挖掘，我看到self.client正在'unix://var/run/docker.sock'上查看docker_url
但是在这个link中，我看到/var/run/docker.sock在OS上并不存在，相反，一个回复说
/var/run/docker.sock不会在您的OSX文件系统上- Docker守护进程在boot2docker虚拟机内部运行-而这正是unix套接字所在的位置。
该串行文件也与docker套接字无关。
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，如此模块的描述所示：
运行docker_url:描述：-要向其发出命令的docker主机的URL必需: false默认值:unix://var/
/docker.sock别名：[]
但是当我将它设置为DOCKER_HOST地址时，我得到了一个错误。
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下面是错误：
failed: [localhost] => {"changed": false, "failed": true}

您的第一个配置几乎是"ok“的，需要更改两件事
tasks: ...
path: ./test
state: present在本例中，ansible的根目录就是您的main.yml文件所在的位置。
cookbook/
├── main.yml
└── test
└── Dockerfile因此，main.yml的内容将保留如下
---
- hosts: localhost
connection: local
tasks:
- name: Build docker image from dockerfiles
docker_image:
name: testimage
path: ./test
state: present状态需要根据doc被呈现为

作为变通办法，您可以使用代理“socket -container”，它将您的请求从tcp地址路由到unix套接字。看看这个page。boot2docker上的端口2376只适用于ipv6，而不适用于ipv4 (我发现没有办法改变这一点，我没有更深入地研究这个问题，也不喜欢对boot2docker虚拟机进行更改的想法)。我还在VirtualBox中为我的本地主机添加了NAT转换(ansible inventory本地主机)
要小心使用ansible和docker-py
您需要：
- ansible 1.9.2
- docker_api_version: 1.18
这对我很有效。

如果你想用Ansible构建docker镜像，我建议你看看Ansible Container，这是一个来自Ansible的开源项目，专门专注于构建docker镜像。
Ansible Container使您能够使用现有的/自己的Ansible角色来构建docker镜像。
