ansible:将变量传递给处理程序 [英] ansible: pass variable to a handler
问题描述
我使用眼睛"作为主管,并且在模板更改上必须运行以下内容:
I use an "eye" as a supervisor and on changes in templates have to runs something like this:
eye load service.rb
eye restart service.rb
我想将其定义为所有应用程序的单个处理程序,并像这样调用它
I want to define this as a single handler for all the apps and call it like
eye reload appname
在处理程序中,操作如下:
And in a handler operate like this:
- name: reload eye service
command: eye load /path/{{ service }}.rb && eye restart {{ service }}
但是我找不到将变量传递给处理程序的方法.有可能吗?
But I can't find a way to pass variable to a handler. Is it possible?
推荐答案
handlers/main.yml:
handlers/main.yml:
- name: restart my service
shell: eye load /path/{{ service }}.rb && eye restart {{ service }}
因此您可以通过默认设置变量 默认值/main.yml:
So you can setup variable through default defaults/main.yml:
service : "service"
或者您可以通过命令行定义{{service}}:
or you can define {{ service }} though command line:
ansible-playbook -i xxx path/to/playbook -e "service=service"

example
---
- hosts: webservers
vars:
http_port: 80
max_clients: 200
remote_user: root
tasks:
- name: ensure apache is at the latest version
yum: name=httpd state=latest
- name: write the apache config file
template: src=/srv/httpd.j2 dest=/etc/httpd.conf
notify:
- restart apache
- name: ensure apache is running (and enable it at boot)
service: name=httpd state=started enabled=yes
handlers:
- name: restart apache
service: name=httpd state=restarted

如果您希望在1.2及更高版本中立即刷新所有处理程序命令,则可以:
If you ever want to flush all the handler commands immediately though, in 1.2 and later, you can:
tasks:
- shell: some tasks go here
- meta: flush_handlers
- shell: some other tasks
