This could be the most straight forward MacOS update I have ever performed (I have been doing them since System 7.5↗ ). This time all three machines (iMac, MBP and MBA) worked first time with no dramas. As always the first thing I did was a full TimeMachine back-up (I have been burnt before) and then downloaded a copy of the Yosemite install from the AppStore. Rather than do an in-place upgrade I always do a clean installation, for the last three releases I have used the excellent DiskMaker X (or Lion Disk Maker as it used to be known)↗ . Once I have a USB installer I rebooted into the USB disk and then erased my primary hard drive using the disk utility, which is always a fun moment. ...

On Friday DigitalOcean announced the availability↗ of CoreOS↗ on their platform. CoreOS is a very optimized Operating System which is designed to just run containers.

This means that there is always a lot of new shinny things to play with such as ….. ...

I just noticed that the first post on this blog was made exactly a year ago today. While the layout and blogging engine has changed and I have not posted for extended periods of time happy birthday to me.

I have been installing and exposing SSH on most of the containers I have deployed, which I know is wrong. As I have been trying to do things in a more “devops” way I decided to do a little reading on how I can enter and leave running containers on my CentOS 7 instance without having to expose SSH or configure users. This is when I came across nsenter↗ & docker-enter↗ . As you can see from the following instructions and terminal session installing nsenter and then using docker-enter to connect to a running container is a breeze; ...

At least once a day I skim through a large number of blogs in my Feedly↗ feed using Reeder 2↗ , when I see something which catches my eye I send it over to Pocket↗ so it is sync’ed to all of my devices. Here are some of the posts I have saved for further reading ….

The I came across Bashstrap↗ , it was close enough to what I wanted so I forked it↗ …. You can install them using the following commands; ...
