One of the reasons I haven’t been posting much on here for the last fews months is that I have been busy spending my weekends and evenings writing a book called “Monitoring Docker” which is being published by Packt Publishing↗ at the end of the year. It’s now available for pre-order from the Packt website↗ and also Amazon !!! Exciting times :D
Every six months or so I like to do clean installs of all of my Macs. I try and time this for late September which is normally when Apple releases its latest updates. This year its OS X 10.11 El Capitan; First thing to do is build a USB install disk so that , to do this I use DiskMaker X↗ . Once the drive has been created I boot from it, erase “Macintosh HD” and then do the installation....
A while I posted about a script I wrote to quickly bootstrap a Digital Ocean droplet. 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;...
I have a need to create both some Ubuntu and CentOS Vagrant boxes for a project I am working on. Normally I would have created them on my local machine, uploaded the artifacts to an Amazon S3 bucket and then published them using Atlas↗ (formally Vagrant Cloud↗ ). However in the past month HashiCorp↗ have updated Atlas so that you can now build Packer↗ templates directly within Atlas and publish the artifacts as Vagrant Boxes, all free of charge....
In my previous post I wrote about launching a CentOS 7 Virtual Machine in Azure↗ using Terraform↗ . As you can see from my original configuration I was adding a password and my own user. This worked well, the machine launched and I could access it as expect and sudo to root. However, when it came to using Terraforms built-in provisioner I started to have problems as the commands I was running need root privileges, when I tried using sudo it would sit there waiting for the password to entered....
As regular readers will know I really like the tools provided by Hashicorp↗ and today I found an excuse to use one. I needed to bring up a Virtual Machine in Microsoft Azure↗ . I hadn’t logged into Azure for quite a while so imagine my shock when I opened the dashboard, it’s not that great and the beta of the new one isn’t that brilliant either. It was so bad I tweeted about it …....
Last night I did some I haven’t done for a while and watched the opening episode of a new Dragons Den↗ series while it was being aired. After a short time I found myself less interested in what was happening on screen and more interested in what was happening to the contestants (this is after all a primetime game show isn’t it?) websites during what should be a predicted spike in traffic....
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↗ ....
