This work was initially based on benjojo/alertmanager-discord but has mostly been rewritten.
Give this a webhook (with the DISCORD_WEBHOOK environment variable) and point it as a webhook on alertmanager, and it will post your alerts into a discord channel for you as they trigger.
Example alert manager config:
global:
# The smarthost and SMTP sender used for mail notifications.
smtp_smarthost: 'localhost:25'
smtp_from: 'alertmanager@example.org'
smtp_auth_username: 'alertmanager'
smtp_auth_password: 'password'
# The directory from which notification templates are read.
templates:
- '/etc/alertmanager/template/*.tmpl'
# The root route on which each incoming alert enters.
route:
group_by: ['alertname']
group_wait: 20s
group_interval: 5m
repeat_interval: 3h
receiver: discord_webhook
receivers:
- name: 'discord_webhook'
webhook_configs:
- url: 'http://localhost:9094'
