Ansible Playbook
After generating the token now its time to configure the Ansible playbook to send notifications to Slack. Here is my Ansible playbook to send the notification. In the playbook I checked the status of httpd services and it will send the status on slack channel.
---
- hosts: "{{ hosts }}"
- name: Status of Apache
command: service httpd status
register: output
- name: Send notification to Slack
local_action:
module: slack
token: *****/******/*************
channel: "#ansible"
msg: "Status of apache on host {{ ansible_hostname }} is {{ output.stdout_lines }}"It will send notification to ansible channel on slack.
