At the start of this month Docker purchased a storage startup called Infinit↗ . We’re joining @docker! 🐳 🎉 https://t.co/iCTBd0bWLw — Infinit (@infinit) December 6, 2016 Up until then I had only heard of their commercial offering which can be found at https://infinit.io/↗ which on the face of it has nothing to do with container storage and is a Dropbox equivalent. Concepts Before we roll our sleeves up and install, configure & user Infinit we need to cover a few of the terms. ...

Earlier this week I wanted to show someone a copy of Rancher↗ running but I realized that I didn’t have a local lab configured. I managed to quickly launch a few machines in Digital Ocean↗ 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. Rancher provides a full set of infrastructure services for containers, including networking, storage services, host management, load balancing and more. All of these services work across any infrastructure, and make it simple to reliably deploy and manage applications. ...

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; Falco by sysdig 1/6 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. On Windows, the Docker Engine is running in a Hyper-V VM. You do not need Docker Machine (docker-machine) to run Docker for Mac and Docker for Windows. ...

As mentioned in my previous post I have been doing a lot of work with Docker Machine↗ and Docker Swarm↗ 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↗ 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↗ ; 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↗ ...

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. This is great for me as it means that I will not incur the hosting and distribution costs. ...

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↗ . ...
