playlabs-the-obscene-ansible-distribution-for

https://playlabs.readthedocs.io/en/latest/ Playlabs documentation is now available online ! Playlabs provides a convenient wrapper for the ansible-playbook command and provides a set of ansible roles made to work together, and to orchestrate containers as much as possible and let only network level provisioning happen on hosts themselves, and combines straigthforward ansible patterns to install a docker orchestrated paas infra to prototype products for development to small-size production. Pre-beta state: works for me, but parts are being rewriten independently until it’s clean enough and declared stable, documentation is still in progress and so are tests. [Read More]

Test Driven Development with SaltStack SLS code

Getting started with SaltStack usually means piling up a bunch of YAML code templated with Jinja in a source code repository because that’s the way to go from the documentation’s point of view. With significant whitespace, YAML enables even non-developers to define data structures in non verbose way. Jinja2 is a templating engine which enables a non-developer to make YAML files dynamic, typically depending on variables. However, Jinja2 hasn’t significant whitespace and this can decrease readability of YAML templates. [Read More]

Testing SaltStack formulas on Travis-ci

SaltStack is an Open Source DevOp tool to automate administration of a computer (server or desktop) infrastructure, typically but not limited to, developing in-house PaaS. Travis-ci is an Open Source Continuous Integration platform and online-hosted for free for Open Source projects. This article targets SaltStack formula developers who wants to have CI enabled and of course every SaltStack user should be a formula developer wanting CI. Overview First things first, we have to test the /pillar. [Read More]

Scripted Cache AnyThing - HTTPS included - in Python with mitmproxy

The last article demonstrated how we could simply make any https flow going out a virtual bridge network interface through mitmproxy to cache anything. In this article, we’ll focus on the logic to “cache anything” from within our mitmproxy script. Design We’d like each fetched file to be stored in a directory as is to make it easy to tweak the cached content: remove a file from the cache directory to force the proxy to re-fetch it, fill the cache directory with your own files, have the cache directory mountable in a memory (ie.

Scripted MITM AnyThing in Python with mitmproxy

This article describes how to get a working transparent HTTP/HTTPS proxy which you can script in Python. I intend to use it to have custom caching and be able to abstract away all HTTP/HTTPS connections made in my LXC containers which are spawned by CI to be able to test deployment scripts even when internet is down. A nice journey ;) First, install mitmproxy with pip: pip install mitmproxy mitmproxy documentation describes the iptables commands to intercept Assuming you have LXC with Nat. [Read More]
