是否可以在 Ansible Playbook 中操作日期 [英] Is it possible to manipulate the date in an Ansible Playbook
问题描述
我在我的一本剧本中使用了 ansible_date_time.hour
和 ansible_date_time.minute
.
Am using the ansible_date_time.hour
and ansible_date_time.minute
in one of my playbooks.
但我需要为这些事实(或在变量中)添加时间.即如果 ansible_date_time.hour
返回 16 - 我想添加几个小时,或者如果 ansible_date_time.minute
返回 40 - 我希望它是 50..
But I need to add time on to these facts (or in a variable).. i.e. if ansible_date_time.hour
returns 16 - I want to add a couple of hours, or if ansible_date_time.minute
returns 40 - I want it to be 50..
当然,小时和分钟有 23 和 59 的上限......因为我想从以下位置注册一个变量:
Of course there is a ceiling of 23 and 59 for the hours and mins... as I thought about registering a variable from:
- name: Register HH
shell: date '+%H'
register: HP_HH
- debug: msg="{{ HP_HH.stdout | int + 3 }}"
但显然,如果我的剧本在 21:00 之后运行,我就不走运了.
But obviously if my playbook runs at after 21:00 I am out of luck.
有人有建议或解决方法吗?
Does anyone have a suggestion or workaround?
推荐答案
AFAIK,在 Ansible 中无法开箱即用地添加/减去时间单位.
AFAIK, there is no way to add/subtract time units out of the box in Ansible.
您可以使用 to_datetime
过滤器 (Ansible 2.2+) 将字符串转换为 datetime
对象.
您可以计算日期差异.请参阅此答案.
You can convert strings to datetime
object with to_datetime
filter (Ansible 2.2+).
You can calculate date difference. See this answer.
但如果您不介意使用简单的过滤器插件,那么您可以:
But if you don't mind using a simple filter plugin, here you go:
将此代码作为 ./filter_plugins/add_time.py
放在您的剧本附近:
Drop this code as ./filter_plugins/add_time.py
near your playbook:
import datetime
def add_time(dt, **kwargs):
return dt + datetime.timedelta(**kwargs)
class FilterModule(object):
def filters(self):
return {
'add_time': add_time
}
您可以使用自己的 add_time
过滤器,如下所示:
And you can use your own add_time
filter as follows:
- hosts: localhost
gather_facts: yes
tasks:
- debug:
msg: "Current datetime is {{ ansible_date_time.iso8601 }}"
- debug:
msg: "Current time +20 mins {{ ansible_date_time.iso8601[:19] | to_datetime(fmt) | add_time(minutes=20) }}"
vars:
fmt: "%Y-%m-%dT%H:%M:%S"
add_time
与 timedelta<具有相同的参数/a> 在 Python 中.
add_time
has same parameters as timedelta in Python.
