Running Docker containers on Windows, natively, using rkt (WSL aka Bash on Windows)

Just a heads up for those who are looking into running Docker containers natively on WSL. While it's not usable for anything serious (even your toy project development), there is a way.

Nuances:

  • We'll be using rkt and not Docker. So, no docker-compose for you.
  • There will be some source code patching. Nothing serious, just a few lines.
  • Very limited isolation and networking capabilities. Think of always --privileged, --net-host and no DNS.

WSL doesn't have cgroups at the moment, and probably won't have them anytime soon, so no way Docker would work.

Experiment with django-money to have multiple money fields that share the single currency. May contain bugs, use with extreme caution.
from __future__ import absolute_import, unicode_literals
from djmoney.models.fields import MoneyField, MoneyFieldProxy
class CurrencyLockedMoneyFieldProxy(MoneyFieldProxy):
def __init__(self, field, currency_field_name=None):
super(CurrencyLockedMoneyFieldProxy, self).__init__(field)
if currency_field_name is not None:
self.currency_field_name = currency_field_name

An somewhat ugly hack to make packets to certain IPv4 addresses not increment interface counters. Original patch's not mine.
