This is yet another accidental purchase of a self-published book, although I think this one makes a lot of sense as a self published work. Writing a technical reference book isn’t a particularly lucrative pastime for most authors, and self publishing likely makes it more worthwhile than the traditional publisher route, especially if you can…
My team at work now has a daily personal learning time called “egg time” — its a slightly silly story involving a manager who was good at taking some time to learn things each day, and an egg shaped chair. Today I decided that I should read this paper about container image loading in AWS…
I’ve been playing again with Docker images and their internal layers a little more over the last week — you can see some of my previous adventures at Manipulating Docker images without Docker installed. The general thrust of these adventures is understanding the format and how to manipulate it by building a tool called Occy Strap…
Recently I’ve been playing a bit more with Docker images and Docker image repositories. I had in the past written a quick hack to let me extract files from a Docker image, but I wanted to do something a little more mature than that. For example, sometimes you want to download an image from a…
There are a few online training resources I’ve had a play with while learning Kubernetes, so I figure that’s worth a quick write up. This is a follow on from my post about Kubernetes podcasts I’ve tried. I’ve tried three training providers so far: The Linux Foundation Kubernetes course (LFS258 Kubernetes Fundamentals) is probably the…
It has become clear to me that it is time to care about Kubernetes more. I’m sure many people have cared for ages, but the things I want to build at the moment are starting to be more container based now that I am thinking more at the application layer than the cloud infrastructure layer….
Hello! Please note I’ve written a little python tool called Occy Strap which makes this a bit easier, and can do some fancy things around importing and exporting multiple images. You might want to read about it? For various reasons, I wanted to inspect the contents of a Docker image without starting a container. Docker…
I’m doing the Linux Foundation Kubernetes Fundamentals course at the moment, and I was very disappointed in the chapter on Ingress Controllers. To be honest it feels like an after thought — there is no lab, and the provided examples don’t work if you re-type them into Kubernetes (you can’t cut and paste of course,…
This is the second in my set of posts discussing the outcomes from the OpenStack nova juno mid-cycle meetup. I want to focus in this post on things related to container technologies. Nova has had container support for a while in the form of libvirt LXC. While it can be argued that this support isn’t…
