Webhook Configuration

New as of 1.4.0

You can configure as many webhooks as you like. Each webhook consists of 2 ENV variables:

  • CIAO_WEBHOOK_ENDPOINT_$NAME
  • CIAO_WEBHOOK_PAYLOAD_$NAME

$NAME can be any word [A-Z0-9_] and must be unique as it is used as an identifier.

like:

# Webhook for Rocketchat
CIAO_WEBHOOK_ENDPOINT_ROCKETCHAT="https://webhook.rocketchat.com/***/***"
CIAO_WEBHOOK_PAYLOAD_ROCKETCHAT='{"text":"[ciao] __name__: Status changed (__status_after__)"}'

# Webhook for Slack
CIAO_WEBHOOK_ENDPOINT_SLACK="https://webhook.slack.com/***/***"
CIAO_WEBHOOK_PAYLOAD_SLACK='{"text":"[ciao] __name__: Status changed (__status_after__)"}'

etc.

There are 5 placeholders which you can use in the payload:

  • __name__
  • __url__
  • __status_before__
  • __status_after__
  • __check_url__

ENV variable CIAO_WEBHOOK_PAYLOAD_$NAME has to be a valid JSON one-liner wrapped in single quotes like '{"name":"__name__", "status_before":"__status_before__", "status_after":"__status_after__", "check_url":"__check_url__", "url":"__url__"}'

Notes

  • If you are using docker-compose, you have to omit the outer "" and '' in *_ENDPOINT_* and *_PAYLOAD_* - take a look at these GitHub issues (1, 2) and these Stack Overflow questions (1, 2)
  • You can add an Example configuration for a Service that's missing in the list via PR
