  • Painless Immutable Infrastructure with Ansible and AWS | Radify Blog – […] In our blog posts Reducing Infrustration and Immutable Demo Nodes, we talk about our approach to immutable infrastructure and the benefits we have seen from employing this approach. In this article, we explore a practical project example so you can get up and running with immutable infrastructure in less than an hour! […]

  • Provisioning EC2 Hosts with Ansible | Allan Denot – Looking to build EC2 hosts with more consistency? Using Ansible you can easily provision EC2 hosts and put some logic on it to adjust EC2 parameters based on the type of host you are building.
    The easiest way to start is to create a playbook calling the ec2 module with the parameters you want to pass to AWS to create your host. In this post I will show a little more scalable way to do this, where the parameters are variables and you can easily have multiple types of hosts sharing the same playbook and role.

  • Coderwall | Dump all variables – For debugging purposes it can be useful to not just dump hostvars but also all other variables and group information. You can do this using a jinja template which you could include in a debug task
  • Using Ansible to create AWS instances | Tivix – Ansible is a great tool for enhancing productivity. With a vast array of modules to choose from, it can save you a lot of time by automating away common tasks. At Tivix we use it for single-command deployment, with the most common destination being Amazon EC2 instances created beforehand. Since Ansible is capable of managing EC2 resources, we can improve this setup by making a playbook to create an instance for us.
  • Home | OpenSCAP portal – The OpenSCAP ecosystem provides multiple tools to assist administrators and auditors with assessment, measurement and enforcement of security baselines. We maintain great flexibility and interoperability, reducing costs of performing security audits.
    The OpenSCAP project provides a wide variety of hardening guides and configuration baselines developed by the open source community, ensuring that you can choose a security policy which best suits the needs of your organization, regardless of its size.
    SCAP is U.S. standard maintained by National Institute of Standards and Technology (NIST). The OpenSCAP project is a collection of open source tools for implementing and enforcing this standard, and has been awarded the SCAP 1.2 certification by NIST in 2014.

  • Hardening Framework – […] Server hardening is a well-known topic with many guides out in the wild. Why this project? At Deutsche Telekom we need to manage thousands of servers for customers and ourselves. All servers need to be configured properly and maintained, which is difficult and time-consuming to get right. To answer these needs for security, compliance, and maintainability, we decided to launch this project as a common ground for requirements and their fulfillment.[…]

  • Come suddividere il log di WordPress in file separati tramite Apache – Otherplus Tech – Quando usiamo WordPress su un server Apache siamo quasi sempre abituati ad avere un solo file di log per gli accessi del nostro sito e alcune volte due file per dividere gli accessi normali da quelli in errore. Ultimamente ho avuto un’esperienza da un cliente proprio su questo argomento specifico e abbiamo dovuto generare i file in maniera tale da dividere le informazioni che riguardavano la sezione classica da quella admin, ajax, wp-content etc.
  • Using AWS Virtual Tape Library as Storage for Bacula – CAPSIDE – In this article, we will set up a Storage Gateway virtual machine on-premises that will cache and buffer backup data from Bacula.
  • Tiny Puppet – Yet Another Puppet Abstraction Layer – Tiny Puppet is a Puppet module that allows management of virtually any application on any Operating System: It’s based on the assumption that its user knows and wants to control how to shape the managed application’s configuration file: It’s not a joke, it just works like that, as long as our application can be installed via a native package (Tiny Puppet can manage also additional repos) and we know how to configure it.

  • IT Landscape for sysadmins –
  • MonitoringScape – The past decade has seen a dramatic shift in how we build applications: clouds, containers and micro-services have displaced the old paradigm of static, monolithic infrastructure. The need for operational visibility has grown tenfold. Thankfully, the monitoring landscape has kept up with the times. We now have a choice of over 100 monitoring tools that provide excellent visibility to every nook and cranny of our IT stack. The modern monitoring landscape has something for everyone: on-prem installations, SaaS applications, open-source tools and high-priced enterprise monitoring suites. However, with so many tools to choose from, the monitoring landscape can be difficult to navigate. MonitoringScape is your guide to the new, exciting world of modern monitoring. Keep in mind that this is a community resource, so your comments and suggestions are very welcome.
  • Provision and Bootstrap AWS instances with Chef – This is continuation of the previous post called Provision with Chef – baby steps. Today we going to talk about the process of bootstrapping instances with Chef used by FastCompany
  • Provision machines with AWS – custom bootsrapper – […] Now I will tell a little more about our instance bootstrap process. Basically at the end of the previous post we discussed tree possible options for automated machine startup: Create different AMI for each server role. Install all binaries into one ami an provide a way to load dynamic configs parts through some custom bootstrap script. Use infrastructure automation framework like Chef or Puppet, which could handle installs and configuration for you. […] [ Note: the article is pre chef-provisioning tool ]

We will set up a centralized Chef server which will store and serve configuration instructions and node profiling information. We will also set up a workstation where the administrator can work with the code base and alter the characteristics of the infrastructure. We will follow this up by bootstrapping a new node to bring it under the management of the Chef ecosystem.

Upgrades can be performed, backups can be generated, new posts can be published and most of the regular admin actions can be performed with a set of commands. In this tutorial we will explain how to use the WP command line interface in order to complete regular administrative tasks like upgrades, database backup creation, plugins and themes installations and removals, publishing and deleting posts, changing site's URL settings and getting help on chosen commands. Note that WP-Cli requires an SSH access.

  • How to write udev rules – Since the adoption of Kernel 2.6, Linux has used the udev system to handle devices such as USB connected peripherals. If you want to change the behavior when you plug something into a USB port, this section is for you. As an example, we will use a USB thumb drive but these methods should translate to any device handled by udev. As a goal for this exercise we decided to create a symlink and execute a script when a specific thumb drive was loaded.

The way that e-mail was originally designed to work. We’ve all just forgotten because, you know, webapps-n-stuff. It’s a lot of work, mkay, and I’m a lazy software developer.
