我想更新INI配置文件。
今天,我以这种方式将我的信息存储在var文件中(在group_vars中):
# Identity configuration information
identity_servers_conf:
DEFAULT:
admin_token: "{{identity_admin_token}}"
verbose: True
database:
connection: "mysql://{{ identity_db_user }:{{ identity_db_password }}@{{ db_lb_name }}/{{ identity_db }}"
token:
provider: keystone.token.providers.uuid.Provider
driver: keystone.token.persistence.backends.sql.Token
在我的Ansible任务中,我以这种方式使用这些信息:
- name: configuration / modify keystone.conf ini file DEFAULT section
ini_file:
section: DEFAULT
dest: /etc/keystone/keystone.conf
option: "{{item.key}}"
value: "{{item.value}}"
with_dict: identity_servers_conf['DEFAULT']
有没有办法在每个"部分"中迭代我的dict文件?参数,即DEFAULT,数据库,令牌。事实上,我试图找到一种方法来在with_items循环中嵌套._ / p>
答案 0 :(得分:4)
我发现这种组织.ini文件变量的方式非常有趣。
我想自己使用它,所以我开发了一个插件,允许使用inifile模块一次性生成.ini文件的所有键。
它工作正常,我用来管理我的OpenStack配置文件。
我不是开发方面的专家,但我认为这个插件对每个人都有用,所以如果有人想接管维护并将其整合到ansible中,欢迎他。
该插件转换列表中的层次结构数据(section,key,value),以便直接与inifile模块with_inidata一起使用,如下所示:
vars文件:
...
glanceapi_conf:
DEFAULT:
verbose: "{{ image_log_verbose }}"
rabbit_host: "{{ amqp_host }}"
rabbit_port: "{{ amqp_port }}"
rabbit_userid: "{{ amqp_userid }}"
rabbit_password: "{{ amqp_password }}"
rabbit_ha_queues: "{{ amqp_ha_queues }}"
database:
connection: "mysql://{{ image_db_user }}:{{ image_db_password }}@{{ db_host }}/{{ image_db }}"
keystone_authtoken:
auth_uri: "http://{{ identity_admin_host }}:{{ identity_api_port }}/v2.0"
identity_uri: "http://{{ identity_admin_host }}:{{ identity_admin_port }}"
admin_tenant_name: "{{ image_ks_tenant }}"
admin_user: "{{ image_ks_user }}"
admin_password: "{{ image_ks_password }}"
paste_deploy:
flavor: keystone
glance_store:
default_store: file
filesystem_store_datadir: /var/lib/glance/images/
...

class LookupModule(object):
def __init__(self, basedir=None, **kwargs):
self.basedir = basedir
def run(self, terms, inject=None, **kwargs):
terms = utils.listify_lookup_plugin_terms(terms, self.basedir, inject)
if not isinstance(terms, dict):
raise errors.AnsibleError("inidata lookup expects a dictionnary , got '%s'" %terms)

raise errors.AnsibleError("inidata lookup expects a dictionary, got '%s'" %terms[item0])
for item1 in terms[item0]:
ret.append((item0, item1, terms[item0][item1]))
return ret
任务代码:
- name: configuration.modify_glance-api_conf_file / modify glance-api.conf ini file
ini_file:
section: "{{ item.0 }}"
dest: /etc/glance/glance-api.conf
option: "{{ item.1 }}"
value: "{{ item.2 }}"
backup: yes
with_inidata: glanceapi_conf
要使用它,只需在/etc/ansible.cfg中定义的目录中复制名为“dataini”的插件代码。
对于Ubuntu发行版,这应该是/ usr / share / ansible_plugins / lookup_plugins,并按照我的示例编写您的任务。
我希望这个插件可以让你简化你的ini文件管理。
