How to recover lost Python source code if it's still resident in-memory

I screwed up using git ("git checkout --" on the wrong file) and managed to delete the code I had just written... but it was still running in a process in a docker container. Here's how I got it back, using https://pypi.python.org/pypi/pyrasite/ and https://pypi.python.org/pypi/uncompyle6

Attach a shell to the docker container

Install GDB (needed by pyrasite)

apt-get update && apt-get install gdb

drop
not ethertype ipv4
and not ethertype arp

Motivation

Use a Raspberry Pi as a bridge into my home LAN. The pi is plugged into a switch, which is plugged into an airport express, which is plugged into a cable modem; Nothing fancy.

This isn't a tutorial. Just some example output from a working setup.

steps

off the top of my head, here's the order I would do it in:

make sure plain old device to device zerotier is working with my LAN/Router/Firewall/ISP
