blog-pinger

This repository is an OpenFaaS stack I use to ping my blog and report back on a slack channel if the ping fails.

This has an accompanying blog post you can find here: http://jmkhael.io/downnotifier-site-pinger/

This is a high level view of what is in this repository:

In the top section you can find logs of an OpenFaaS function, the brain of all this, in the bottom section I invoke this function on an inexistant site, and on the right you can see an incoming message to Slack with the site down information!

TLDR;

1. Adapt the token in samples.yml as specified in slack_it

2. build and deploy

   ./build.sh
   ./deploy.sh http://jmkhael.io

3. Test the individual functions ./test.sh

If everything works fine, you should see something like the below.

{"url":"http://jmkhael.io/","status":"ok","status_code":200}
Initializing Botkit v0.5.6

{"slackit":"v1","request":{"message":"Anything really"}}
{"DownNotifier":"v1","request":{"url":"http://jmkhael.io"},"response":"all ok - slack not informed"}

1. Profit!
