Question

Prudentia找不到我定义的方框。我很确定盒子在那里。当我使用绝对路径时，它会抱怨Ansible中的$prudentia_dir。

这是我的目录树：

deployment/
|-- Readme.md
|-- boxes
|   |-- common_vars.yml
|   |-- dev.yml
|   |-- dev_vars.yml
|   |-- enable_cd.yml
|   |-- staging.yml
|   `-- staging_vars.yml
`-- components
    |-- api.yml
    |-- base.yml
    |-- client.yml
    |-- files
    |   `-- ssh
    |       |-- id_rsa
    |       `-- id_rsa.pub
    |-- mongo.yml
    `-- templates
        |-- api
        |   |-- logback.xml.j2
        |   `-- upstart.conf.j2
        `-- client
            `-- nginx.conf.j2

当我启动Prudentia SSH并尝试注册一个框时：

(Prudentia > Ssh) register
Specify the playbook path: deployment/boxes/staging.yml
25-06-2014 18:48:35.339 [root] ERROR: Box not added.
Traceback (most recent call last):
  File "/Users/rob/tmp/prudentia/src/ssh.py", line 26, in register
    hostname = self.fetch_box_hostname(playbook)
  File "/Users/rob/tmp/prudentia/src/simple.py", line 202, in fetch_box_hostname
    with open(playbook, 'r') as f:
IOError: [Errno 2] No such file or directory: 'deployment/boxes/staging.yml'

There was some problem while adding the box: [Errno 2] No such file or directory: 'boxes/staging.yml'

在对相对路径应该是什么的不同假设进行了几次尝试之后，我决定使用绝对路径。在该尝试上发生以下错误：

(Prudentia > Ssh) register
Specify the playbook path: /Users/rob/......./deployment/boxes/staging.yml
Specify the box name [default: acme-staging]:
Specify the address of the instance: poc01
Specify the remote user [default: rob]: pocuser

    raise errors.AnsibleError("file could not read: %s" % path)
AnsibleError: file could not read: /Users/rob/dev/...../components/$prudentia_dir/tasks/mongodb.yml

There was some problem while adding the box: file could not read: /Users/rob/...../deployment/components/$prudentia_dir/tasks/mongodb.yml

之后，Prudentia退出并在每次尝试再次启动时失败并出现相同的错误。

似乎Prudentia对于如何使用它有一些假设，我不明白。请帮助1）解决我的情况（失败的Prudentia）和2）防止它再次发生。

查看staging.yml内部。应该以这种格式指定路径：

"{{prudentia_dir}}/tasks/common-setup.yml"

而不是：

$prudentia_dir/tasks/common-setup.yml

可能您正在使用以前版本的盒式文件，并使用较新的prudentia版本。

Answer 2

使用剧本的绝对路径绝对是在注册新盒子时使用的正确方法，我们将在下一个版本中更明确地提出问题。

关于另一个问题@DmitryEvsee是对的，问题是由于Ansible 1.6的更新部分。

我有类似的问题：

File "/Users/iwein/projects/prudentia/p-env/lib/python2.7/site-packages/ansible/utils/__init__.py", line 551, in parse_yaml_from_file
raise errors.AnsibleError("file could not read: %s" % path)

ansible.errors.AnsibleError：文件无法读取：/Users/iwein/projects /.../deployment/boxes/$prudentia_dir/tasks/common-setup.yml

我编辑了~/projects/prudentia/env/ssh/.boxes.json（这是我的审核结果所在的地方）并删除了所有内容。然后prudentia开心了。

接下来我注册了...框，但它再次抱怨：

There was some problem while adding the box: file could not read: /Users/iwein/projects/…/deployment/boxes/$prudentia_dir/tasks/common-setup.yml

然后我修改了框定义yml文件以使用"{{prudentia_dir}}/whatever"而不是$prudentia_dir。我还必须修改我使用的一些组件。我使用了这个替换模式：:%s/\$([^/]*)(.*)/"{{$1}}$2"/g

之后，一切都应该是好的。
