With the release of Multipass 1.8<\/a>, we are happy to announce that MicroK8s gains M1 Apple Silicone support.<\/p>\n

Installing MicroK8s on an M1 Mac is as simple as it is on an Intel Mac:<\/p>\n

$ brew install ubuntu\/microk8s\/microk8s\n<\/code><\/pre>
Once installed, you will have a running Kubernetes cluster with an arm64 node enrolled.<\/p>\n
$ sysctl -n machdep.cpu.brand_string\nApple M1\n\n$ microk8s kubectl get nodes --label-columns kubernetes.io\/arch\nNAME          STATUS   ROLES    AGE     VERSION                    ARCH\nmicrok8s-vm   Ready    <none>   6m13s   v1.22.3-3+64e63223b19811   arm64\n<\/code><\/pre>
Now we can enable all the MicroK8s addons we\u2019d like to.<\/p>"},{"title":"Running Valheim Server On MicroK8s","link":"https:\/\/josephb.org\/blog\/valheim-microk8s\/","pubDate":"Sun, 28 Feb 2021 12:00:00 +0000","guid":"https:\/\/josephb.org\/blog\/valheim-microk8s\/","description":"

MicroK8s<\/a> is a self contained Kubernetes cluster.  It can be used on most Linux distros and even Windows and Mac.  We’re going to use Kubernetes, provided by MircoK8s, to maintain all of the moving parts of our Valheim server.<\/p>\n
\n  Valheim\n  \n    <\/i>\n    Link to heading<\/span>\n  <\/a>\n<\/h2>\n
Valheim<\/a>, available on Linux and Windows, is currently one of the most popular games on Steam despite only being in early access!  It’s a co-op survival game based in the Viking afterlife; perfect to play with friends across the globe.<\/p>"},{"title":"Running Containerd with Nvidia GPU support","link":"https:\/\/josephb.org\/blog\/containerd-nvidia\/","pubDate":"Fri, 29 Mar 2019 12:00:00 +0000","guid":"https:\/\/josephb.org\/blog\/containerd-nvidia\/","description":"
\n  Motivation\n  \n    <\/i>\n    Link to heading<\/span>\n  <\/a>\n<\/h1>\n
Whether you’re operating the container runtime directly, or using through a\nworkload manager, such as Kubernetes, containerd<\/strong> is a great choice.  It’s\nfaster than Docker<\/strong><\/a>\nand allows running seperate runtimes for\ntrusted and untrusted workloads<\/a>.<\/p>\n

\n  Introduction\n  \n    <\/i>\n    Link to heading<\/span>\n  <\/a>\n<\/h1>\n
Kubernetes is a great platform to run your applications on.  There are plenty of blogs out there that go into why Kubernetes is great, so go read some if you haven’t already.  One of the many great fits is a Django application.  Here, we’ll run through the very basics.<\/p>\n
We’ll deploy this demonstration to Google Cloud Platform as this provides a good foundation to spin up a Kubernetes cluster and required ancillaries.  All of the kubectl<\/code> commands are ambiguous to where you’ve installed Kubernetes.<\/p>"},{"title":"Python 2 is Killing Python","link":"https:\/\/josephb.org\/blog\/py2-killing-py\/","pubDate":"Tue, 25 Jul 2017 18:32:32 +0100","guid":"https:\/\/josephb.org\/blog\/py2-killing-py\/","description":"
This is a rebuttal to the blog post Python 3 Is Killing Python\n<\/a> by Stephen A. Goss.<\/p>\n
At the time that post was written, I may even have agreed with it.  Every project I had to migrate from 2 to 3 seemed a mighty pain and, at that time, felt like there was little benefit forthcoming.  There was always a dependancy or two that wasn’t compatible with 3 and their authors seemed stalwart in keeping it that way.<\/p>"},{"title":"Deploying Kubernetes","link":"https:\/\/josephb.org\/blog\/k8s-juju\/","pubDate":"Wed, 05 Jul 2017 14:18:30 +0100","guid":"https:\/\/josephb.org\/blog\/k8s-juju\/","description":"

This is a step by step guide which will demonstrate deploying a Kubernetes cluster using Juju<\/a> and running a scalable web application on top.  Here, we’ll be using the built in Microbot application in place of a real web application.<\/p>\n
\n  Prerequisites\n  \n    <\/i>\n    Link to heading<\/span>\n  <\/a>\n<\/h1>\n
You will need juju<\/code> and kubectl<\/code> to follow along.  On Linux, these can be installed with Snap (these will need to be run with sudo if you’ve not registered Snap):<\/p>"},{"title":"About","link":"https:\/\/josephb.org\/about\/","pubDate":"Mon, 03 Jul 2017 22:00:00 +0100","guid":"https:\/\/josephb.org\/about\/","description":"

I’ve finally got round to making a new site. My old site was in need of some TLC and that meant Django migrations. Unfortunately, it was so old that that meant playing with South again. I was also using STARSSL for HTTPS, which is no longer supported so I’ve moved to Let’s Encrypt.<\/p>"}]}}
