Don’t blindly trust the Docker ping

Too Long; Didn't Read

I was playing around with the good old <code class="markup--code markup--p-code">ping</code> command in an <a href="https://hub.docker.com/_/alpine/" target="_blank">alpine</a> <a href="https://hackernoon.com/tagged/docker" target="_blank">Docker</a> container today. I wanted to perform a little load test for another service so I experimented with different package sizes (<code class="markup--code markup--p-code">ping -s &lt;size in byte&gt;</code>), which caused me quite a bit of MTU-related frustration (but that’s a different story).
