In my tutorial, I will focus on how to get started with Ansible as a beginner and what specifics are necessary to set it up for BSD systems. We will look at how to use them to make even complex changes easy and repeatable, without worrying about applying these changes multiple times. Modules in Ansible provide the functionality to make changes for all kinds of applications and use cases on the remote systems. Using SSH to securely transport these changes and then translating them to OS-specific commands in an idempotent manner, Ansible is flexible and offers a powerful, YAML-based syntax for bigger deployments called Playbooks. Ansible is a system to manage this complexity by abstracting away the specific parts and let’s administrators focus on defining the tasks that should be executed on the remote machine. is a challenging task for every system administrator. Managing a complex system landscape with various operating systems, applications, versions, patch-levels, etc. Security while using his enthusiasm to work on libiocage and other projects. Working as a software engineer for more than a decade, he now focusses on offensive Stefan Grönke loves free software (occasionally) and the process of making it. This tutorial is inclusive for any development or system administration skill level: Learning materials in form of shell access to a staging environment, that will include working samples of the code developed during this session, will give a global context and invite for hands-on hacking – bring your own dotfiles. Although this talk is mainly held in Python 3 and English we will also interface with other languages by scripting custom data interfaces. We will explore iocage for task automation, learn how build daemonized services and develop our own ephemeral jail service. The Python 3 library and CLI tool libiocage was recently introduced on BSDCan2018.Īfter a recap of the development virtues and most important features of libiocage, this tutorial will dive directly into programatic control of iocage using the Python module. Each compartment can have constrained access to filesystem, network and system resources. Iocage is a FreeBSD jail manager based on ZFS that heavily uses operating system features to define and maintain userland compartments. Advanced container management with libiocage
