Stepping down from Cobbler

This blog post briefly describes how I got involved with the Cobbler Project, what I managed to get done and why I’m (finally) stepping down as the project lead. How I got involved Back in 2011 I was working for the Dutch DoD in the IT Infrastructure department where I was deeply involved with UNIX/Linux systems engineering. At some point we wanted to replace our internally developed deployment solution for something more generic and better maintained (upstream). [Read More]

Improving website management

In a previous post I described how I migrated this static website from Github Pages to Amazon AWS using services like S3, CloudFront, Route 53 and Amazon Certificate Manager. Though the technical result is quite satisfying in terms of features and security, espcially from the view of a visitor. The workflow of updating the website is quite annoying as I have to upload new website content manually to the S3 bucket using the upload feature of the S3 Console. [Read More]

Moving this blog to Amazon AWS

This website has been happily running on Github Pages for quite some time now. And to be honest I’ve never experienced any issues with that service. Also their pricing is pretty awesome, you can’t beat free, right?! ;-). This is a very simple static website which uses Hugo as the site generator. Anyway, I’m moving this blog over to Amazon AWS so that I have an actual “workload” (yes, I like using big words) to work with in order to get some more hands-on experience in using Amazon AWS services.

Provisioning HP firmware with Cobbler

When dealing with a bunch of servers one of the many things you are expected to do frequently is to update your systems firmware. In this blog post I’ll describe how I implemented this process for HP ProLiant DL servers. Since this basically is a systems provisioning issue I prefer that this process to be integrated with my current PXE based deployment infrastructure which is based on Cobbler. Luckily HP does provide a Service Pack for Proliant (SPP) as a bootable ISO which does an unattended firmware update for all supported components (iLO, BIOS, disks, NIC’s, HBA’s, etc), it actually works pretty well.

Boot latest kernel in Fedora 23

For some reason my Fedora 23 Workstation laptop isn’t automatically booting the latest available kernel when kernel updates have been installed. Ofcourse, booting the latest kernel is highly desireable as it increases security by replacing old bugs with new ones :-). In this post I describe the manual method of changing the default boot entry in grub as well as the proper fix for what turns out to be a bug. [Read More]
