It has been a while since I last looked at running Packer 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/: Off the back of this announcement the Rocky Linux project 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, 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, which is the Open Source version of Ansible Tower. I created the following Vagrantfile to launch a CentOS 7 server; # -*- mode: ruby -*- # vi: set ft=ruby : VAGRANTFILE_API_VERSION = "2" Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| config.vm.box = "centos/7" config.vm.provider :virtualbox do |v| v....
Earlier this week the guys over at sysdig 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 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 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. But I have been busy 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....
Around this time last year I blogged about Upgrading my servers to CentOS 7, 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. After a little reading it looks like installing a Puppet Master with Apache and Passenger is a little old fashioned since the release of Puppet Server....
As I have mentioned a few times on this blog I tend to use DigtialOcean to spin up servers for testing and to host some of my projects. I also still use CentOS 7 as my preferred OS. Each time I boot a droplet I run few a couple of tasks to get the server how I prefer it. Run a yum update Enable swap Install & configure Fail2Ban Enable firewalld Install vim-enhanced, deltarpm & enable EPEL As I am lazy and sometimes re-launch instances several times when working on a project I decided to write a quick script to do the above so I don’t have to....
