    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

Virtual hosts

Let's say you want to host domains first.com and second.com.
Create folders for their files:

  
## nginx.conf
# to generate your dhparam.pem file, run in the terminal
openssl dhparam -out /etc/nginx/ssl/dhparam.pem 2048

## ssl.rules
# Basically the nginx configuration I use at konklone.com.
# I check it using https://www.ssllabs.com/ssltest/analyze.html?d=konklone.com
#
# To provide feedback, please tweet at @konklone or email eric@konklone.com.
# Comments on gists don't notify the author.
#
# Thanks to WubTheCaptain (https://wubthecaptain.eu) for his help and ciphersuites.
# Thanks to Ilya Grigorik (https://www.igvita.com) for constant inspiration.
