VPN - Wireguard's the new BOSS!

9 Aug, 2018 Wireguard vpn utilities

Wireguard When Linus endorses something like this Can I just once again state my love for it and hope it gets merged soon? Maybe the code isn’t perfect, but I’ve skimmed it, and compared to the horrors that are OpenVPN and IPSec, it’s a work of art. — Linus Torvalds lkml - 02 Aug 2018 You’ve got to take notice… Can it be true? Is it really possible that he’s giving high praise to somebody’s code?

Moving from 'Kube-cert-manager' to 'cert-manager'

5 Jul, 2018 kubernetes cloud howto devops

In a previous post, I’d covered how to use Kube-cert-manager to automatically create and update TLS certificates from LetsEncrypt.org. Kube-cert-manager was, even then, not seeing a lot of activity and Jetstack’s cert-manager was the project to watch/follow. Given that it was still early days with cert-manager, I used Kube-cert-manager. In the last 6 months, cert-manager has moved quite a bit forward. Also, LetsEncrypt now supports wildcard certificates. Today, I decided to give it a spin and was pleasantly surprised.

Having fun with a kaput monitor

4 Jul, 2018 hardware fun monitor

Couple of weeks ago my ancient 10 year old Viewsonic 19" LCD monitor started going bonkers… Wouldn’t switch on properly - the standby light would just blink. Initially I suspected a contact problem and re attaching the cables seemed to do the trick - the monitor would come up and it would be fine until I swtiched off again. It seemed to be an intermittent problem so not much I could do besides do.

Programming the LEGO Mindstorms EV3 in Linux

12 Jun, 2018 linux virtualbox lego-mindstorms-ev3

We got the kids a Lego Mindstorms set last week. I’ve been eyeing it for quite a few years, but have been waiting for the kids to grow up a bit till they can handle it - especially since LEGOs are costly in general and the Mindstorms kit in particular costs a pretty penny. Anyway, they’ve been having a blast building our first robot - for now with LEGO’s android app over a Bluetooth connection.

Kicking the tires on Rancher 2.0

15 May, 2018 cloud kubernetes rancher tools

While I’d sort of an idea in terms of where Rancher fits in the ecosystem as a cluster management solution, I hadn’t played with it. Also, 1.x of rancher had it’s own orchestration engine and so on and I wasn’t that interested. Fast forward to 2017 and Rancher is putting it’s weight being Kubernetes and going all in. Rancher 2.0 was announced in Sep last and has followed up with a stream of RCs and moved to beta.

git log: One command to rule over your git history

26 Mar, 2018 git tips shell

I don’t know about you but while I’m pretty comfy with git cli for most routine operations, there are a few things that I do like a GUI for - most notably going through git history. Like most of you, I have an alias in my ~/.gitconfig to show logs on one line [alias] lg = log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit --date=relative --date-order While this is usually enough, it’s not for cases when I need to search through history for commits touching a specific file or having some specific word/regex.

Battle of the backup tools

9 Feb, 2018 linux howto backup utilities

I’ve finally set up backup of the different servers at home and in a way that I’m actually satisfied. In the past, it had been just rsync scripts.. needless to say, that it wasn’t working out that well and so things stood. and so things stood. Last week, I was thinking of giving Gnome a try out - I prefer KDE and run KDE Neon user edition on my main machine.

Fail: Minikube on Windows 10 using HyperV

19 Jan, 2018 kubernetes cloud

So I’m stuck on windows 8.1 on my work machine - not that I mind too much.. It’s just too much work to set up the machine from scratch. However, windows 10’s WSL and docker for windows support using HyperV was something I wanted to give a spin. With Azure now supporting nested virtualization, I set up a dev machine on azure on the Dv3 SKU’s and set up minikube on it.

Automatically provision sub-domain and SSL certificates on AKS

16 Jan, 2018 kubernetes cloud howto devops

Recently, I ported a large-ish codebase to .Net core. As part of that, one thing to deal with was continuous integration and continuous delivery. As Kubernetes was the platform of choice, I was looking into options that would let us: Deploy any branch, tag, pull request etc easily. Be able to host multiple app installations side by side. The first was easily solved with creating a Helm chart.
