Earlier this week I wanted to show someone a copy of Rancher external link running but I realized that I didn’t have a local lab configured. I managed to quickly launch a few machines in Digital Ocean external link meaning I could do the demo. Rancher is described as being … From the ground up, Rancher was designed to solve all of the critical challenges necessary to run all of your applications in containers....

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;...

I finally have a beta invite for the native OSX version of Docker, well sort of native OSX version, as you can see from the quote below there is still a virtual machine running … Faster and more reliable — No more VirtualBox! On Mac, the Docker Engine runs in an xhyve Virtual Machine (VM) on top of an Alpine Linux distribution. The VM is managed by the native Docker application....

As mentioned in my previous post I have been doing a lot of work with Docker Machine external link and Docker Swarm external link recently, to configure mulit-host networking with the latest version of Docker I needed to use a service discovery tool. As I had played with Consul external link in the past I decided to use that for my back-end service discovery. Now if I wanted to launch a single node then I would run the following;...

Since the last post about the blog I have been playing with the blog a bit more, I have finally got a decent PageSpeed Insights Score external link ; It’s annoying that the Disqus javascript is keeping me from getting 100/100 but considering before I started to tweak things I was getting a score of 85/100 so I can’t complain too much. I have also adding the following functionality to my Gruntfile external link grunt test — Runs a PageSpeed Insight test from the command line and highlights if either the mobile or desktop test drops below 95/100 grunt grab — Grabs the external Javascript needed to run the site so I can serve it locally....

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 external link (formally Vagrant Cloud external link ). However in the past month HashiCorp external link have updated Atlas so that you can now build Packer external link templates directly within Atlas and publish the artifacts as Vagrant Boxes, all free of charge....

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....

I haven’t installed an ELK stack since CentOS 7 came out, all of the components which go to make up the stack have been updated quite bit since then so I decided to have a go at installing the stack on a clean CentOS 7 installation. ELK? ELK is a term used for a combination of three Open Source products from Elastic external link ; Elasticsearch external link — Search & Analyze Data in Real Time Logstash external link — Collect, Parse, & Enrich Data Kibana external link — Explore & Visualize Your Data All three products can be used independently, but when they are used together you find yourself with both a powerful and scaleable central logging service....
