http-liveness

Probe your web app and get its statistics

It looks like ping on purpose!

Objective

I created this tool to quickily test the uptime of my deployments. This is a great tool to be used while testing downtime for DR failovers, pod rollouts, HA system upgrade, Load Balancers and more.

TL;DR

% docker run -it --rm gfvirga/httpliveness https://www.google.com -c 4

Check https://www.google.com (['172.217.12.206']) response: 200
Check https://www.google.com (['172.217.12.206']) response: 200
