问题描述
我写了一个简单的剧本master.yml，主要功能是查找角色并输入一个作为第二个剧本的输入.但是即使我使用了 var_prompt 角色，它也不会提示输入变量.
I have written a simple play book master.yml,the main function is to lookup the roles and enter one as input for second playbook. But it doesn't prompt for the variables eventhough I used var_prompt role.
--- #master.yml
- name: show roles.
hosts: nodes
connection: ssh
gather_facts: no
tasks:
- include: showroles.yml
- name: createdb and map roles.
hosts: nodes
connection: ssh
gather_facts: no
roles:
- vars_prompt_role
tasks:
- include: createdb.yml
我的目录结构如下:
/playbooks/createdbandmaprole/
[user@localhost createdbandmaprole]$ ls
createdb.yml hosts master.yml roles script.sql.j2 showroles.yml
[user@localhost createdbandmaprole]$cd roles
[user@localhost roles]$ ls
var_prompt_role
[user@localhost roles]$ cd var_prompt_role/
[user@localhost var_prompt_role]$ ls
defaults handlers library main.yml meta tasks vars
[user@localhost var_prompt_role]$ vim main.yml
vars_prompt:
- name: "database"
prompt: "enter the name of database"
private: no
- name: "role"
prompt: "enter the name of role"
private: no
- name: "ad_group"
prompt: "enter the AD_Group"
private: no
[user@localhost createdbandmaprole]$ ansible-playbook master.yml -i hosts --check
但它不提示输入变量
推荐答案
vars_prompt 应该从剧本的顶层调用，而不是任务:
vars_prompt should be called from the top level of the playbook, not a task:
这是一个最基本的例子:
---
- hosts: all
remote_user: root
vars:
from: "camelot"
vars_prompt:
- name: "name"
prompt: "what is your name?"
- name: "quest"
prompt: "what is your quest?"
- name: "favcolor"
prompt: "what is your favorite color?"
因此，根据 此页面.
如果您有一个角色可以调用 vars_prompt，它将在 roles/ 目录下的自己的文件中定义，该目录应该与您的剧本处于同一级别.在您的情况下，它可能如下所示:
If you had a role to call vars_prompt, it would be defined in its own file under a roles/ directory, which should live at the same level as your playbook. In your case, it might look like this:
--- #master.yml
...
- name: createdb and map roles.
hosts: nodes
roles:
- vars_prompt_role
...
然后在 roles/vars_prompt_role/tasks/main.yml 中，您将定义 vars_prompt_role 角色的任务.有关角色的更多信息，请查看此页面，或查看此页面，了解内容组织的最佳做法.
Then in roles/vars_prompt_role/tasks/main.yml, you would define the vars_prompt_role role's tasks. For more information on roles, check out this page, or see this page for best practices on content organization.
这是您的 roles/ 目录的外观:
This is how your roles/ directory should look:
roles/
var_prompt_role/
files/
templates/
tasks/
main.yml
handlers/
vars/
defaults/
meta/
其中 main.yml 是您要为此角色执行的主要任务.
Where main.yml is the main task you want to carry out for this role.
