可以循环x次 [英] Ansible to loop x times

问题描述

我必须做一些基准测试，并遍历10次命令3次(运行所有10x3，而不是第一个x3，然后运行第二个x3-因此运行所有10x3).我从寄存器变量的文件中提取的10条命令(with_lines无效，然后执行该命令)并执行它们1,2,3 ..，10，将输出通过管道传输到文件中，回显某些内容，然后再次执行他们...这3次

I have to do some benchmarks and loop over 10 commands 3 times (run all 10x3, not the firstx3 then the secondx3 - so run all 10x3). The 10 commands I extract from a file in a register variable (it doesn't work with_lines: and then the command) and execute them 1,2,3..,10 pipe the output in a file, echo something and then again execute them... all this 3 times

这就是我在x3下执行代码的方式(nagios_check注册变量中有10条命令/行):

this how I'm doing it the code below x3 (there are 10 commands/lines in the nagios_check registered variable):

... more code above
- name: get the date for naming purpose
  shell: date +%Y%m%d-%HH%MM%SS
  register: dateext
- name: grep the commands from nagios
  shell: grep -R check_http_EDEN_ /etc/nagios/nrpe.cfg | cut -d= -f2-
  register: nagios_check
- name: check_eden_before
  shell: (printf $(echo '{{ item }}' | awk -F'country=' '{print $2}' | cut -d'&' -f1); printf ' ';{{ item }} | cut -d ' ' -f-2) >> {{ ansible_env.DATA_LOG }}/eden-{{ ansible_hostname }}-{{ dateext.stdout }}
  with_items: "{{ nagios_check.stdout_lines }}"
  ignore_errors: True
- name: enter simple line
  shell: echo "=================" >> {{ ansible_env.DATA_LOG }}/eden-{{ ansible_hostname }}-{{ dateext.stdout }}

...上面的这一部分，我编写了3次(全部)，并编写了更多代码

... this part above I have it written 3 times (all of it) and after more code

有没有一种方法可以使它更简单?(它已经是一个角色，我已经使用了该角色4次-不要让我在较小的角色中制动，因为它更加复杂，并且我最终会得到一本巨大的剧本像12x这个角色"这样的东西，看起来会很可怕)

is there a way to make it more simpler ?(it's already a role, I use this role 4 times - don't make me brake it in smaller roles because it's more complex and I'll end up with a huge playbook with something like 12x"this role" and it would look horrible)

推荐答案

您可以将要重复的任务放在单独的yaml文件中:

You can put the tasks you want to repeat in a separate yaml file:

---
# tasks-to-repeat.yml
- name: get the date for naming purpose
  shell: date +%Y%m%d-%HH%MM%SS
  register: dateext
- name: grep the commands from nagios
  shell: grep -R check_http_EDEN_ /etc/nagios/nrpe.cfg | cut -d= -f2-
  register: nagios_check
- name: check_eden_before
  shell: (printf $(echo '{{ item }}' | awk -F'country=' '{print $2}' | cut -d'&' -f1); printf ' ';{{ item }} | cut -d ' ' -f-2) >> {{ ansible_env.DATA_LOG }}/eden-{{ ansible_hostname }}-{{ dateext.stdout }}
  with_items: "{{ nagios_check.stdout_lines }}"
  ignore_errors: True
- name: enter simple line
  shell: echo "=================" >> {{ ansible_env.DATA_LOG }}/eden-{{ ansible_hostname }}-{{ dateext.stdout }}

，然后将其包含在您的剧本中3次:

and then include it in your playbook 3 times:

---
# Your playbook
... more code above
- include: task-to-repeat.yml
- include: task-to-repeat.yml
- include: task-to-repeat.yml
