Linux 🐧

It has been a while since I last looked at running Packer external link locally, when I did CentOS 8 had just been released. Since then, there has been a little drama around the on-going support of CentOS which is best summed up by the following post in /r/sysadmin/ external link : Off the back of this announcement the Rocky Linux project external link has been announced, developed and then released. The project describes itself as follows:...

Now that CentOS 8 has been out for a few weeks I decided it was time to dip my toe in the water and update the CentOS 7 Packer scripts I had to work with CentOS 8. For those that don’t know, Packer by Hashicorp external link , is a tool which allows you to build your own images from a number of sources and use them on a number of platforms — Hashicorp describe Packer as;...

It has been a while as I have been busy writing, I thought I would spend some of my freetime having a very quick play with Ansible AWX external link , which is the Open Source version of Ansible Tower external link . I created the following Vagrantfile to launch a CentOS 7 external link server; # -*- mode: ruby -*- # vi: set ft=ruby : VAGRANTFILE_API_VERSION = "2" Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| config.vm.box = "centos/7" config....

Earlier this week the guys over at sysdig external link announced the availability of Falco, a behavioral security service which is built on top of their core Open Source sysdig engine. As is always the case when I try new things, I launched a Digital Ocean external link Droplet running CentOS 7.2. Once the Droplet was available I ran the command to get the basics configured on the droplet; curl -fsS https://raw.githubusercontent.com/russmckendrick/DOBootstrap/master/do-bootstrap.sh | bash Once the Droplet was configured I installed Falco using the repo provided by sysdig by running the following commands;...

Jenkins has always been a bit of an elephant in the room to me. Not being a developer I have always just shrugged it off a tool used for running unit tests, however, as I moving more into orchestration and automation I am finding the need for a tool which can run both tasks and unit tests, so this weekend I decided to finally take the plunge and have a play around with it....

I have been reading about Flocker external link for quite a while and it’s been something I have been meaning to look at since the introduction of plugins back in the Docker 1.7 release external link . But I have been busy external link looking at other parts of Docker. Since I had a few hours this weekend I thought it was about time and had a play. ClusterHQ describes Flocker as; Flocker is an open-source container data volume manager for your Dockerized application....

A while I posted about a script I wrote to quickly bootstrap a Digital Ocean droplet external link . One one of the things I noticed while trying to install a few packages is that even though my script had run a yum update I was booting into the original Kernel and this was causing all sorts of hilarity when trying to build a Kernel module, because of this I added a few lines to my script to tell you if the kernel has been updated, and if so what the new version is;...

Around this time last year I blogged about Upgrading my servers to CentOS 7 external link , the post contained a link to a script which I wrote to deploy a Puppet Master & Agent and some updated instructions for installing on RHEL / CentOS 7. As those instructions no longer work, and I needed to install a Puppet Master to have a play with I decided to update the installation script....
