基于任务结果的 Ansible 消息输出 [英] Ansible Message Output based on task result
本文介绍了基于任务结果的 Ansible 消息输出的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
是否可以在 Ansible 中根据任务的结果显示不同的消息?
Is it possible in Ansible to display different messages based on a result of the task?
例如
- name: check_prometheus_status_kafka
shell: /usr/sbin/ss -lnt|awk '{ print $4}'|grep 9071 |sed 's/\*//'| sed 's/\://'
register: prom_status
tags:
- check_prometheus_status_kafka
- name: post_message_prom_kafka
debug: msg="Prometheus for Kafka listening in {{ prom_status.stdout }}"
when: prom_status.stdout == "9071"
tags:
- post_message_prom_kafka
我想要的是一个额外的消息,它会输出类似 Prometheus for Kafka 的内容没有监听端口 {{ prom_status.stdout }}
What I want is an additional message which would output something like Prometheus for Kafka is NOT listening on port {{ prom_status.stdout }}
推荐答案
你的问题不是很清楚,但这里有一些东西供你考虑(玩弄actual_port
的值):
Your question is not very clear, but here is something for your consideration (play with the value of actual_port
):
---
- hosts: localhost
vars:
port_to_listen_on: "9071"
actual_port: "9071"
tasks:
- debug:
msg: "Prometheus for Kafka {{ (actual_port == port_to_listen_on) | ternary ('', 'NOT ') }}listening in {{ port_to_listen_on }}"
# or
- debug:
msg: "Prometheus for Kafka {{ 'NOT ' if (actual_port != port_to_listen_on) else '' }}listening in {{ port_to_listen_on }}"
