So That One Time You Played With Docker

Jul 20, 2020

layout: post title: So That One Time You Played with Docker for hte

So that one time, at band camp – wait; wrong movie, this is a technical blog post about Docker …

I recently helped a friend doing some federal work in the medical field get a better understanding of Docker and how Docker can mess about with open source licensing. We got up a "open source" stack of tooling using a bunch of heavy weight tools:

  • Mongo
  • Memcached
  • A big Python app
  • Rabbit MQ

And then, as you so often do, we finished up and I got distracted by the next bit of crazy nerd-fu that runs about in my life (server down; wifi crisis; son needing help with his PC; who can remember) and then I went back to my desk, closed my terminal prompt and never thought much more about this.

Lately I've been noticing some slowness on my machine and I just happened to run docker ps and what do I see but:

docker ps
CONTAINER ID        IMAGE                         COMMAND                  CREATED             STATUS              PORTS                                                 NAMES

Yep. That's the whole set of processes that I was using for my federal friend. Sigh. They've been happily sucking up CPU for more than 2 weeks. grumble

The solution:

docker stop 863768f4f33f dc7f57778b4e df6fd902c11b 0b0eb7730fb0 605da7fe5159
