Bare metal Kubernetes hands on tutorial with MAAS and Juju

In this video tutorial, you will go hands-on and build your own simulated bare metal Kubernetes cluster using just a single computer 💻 with Anton Smith, product manager for MAAS. Along the way, you’ll get to use and learn about some Linux networking, MAAS, LXD, Ceph, Juju and Kubernetes, and at the end deploy an application to your new K8s cluster ✨.

Great video! Thanks!

Holly smackaroons! There's so much room for error! I wonder if 2 years later this is much easier than all these steps... Surely, all these steps can be abstracted away from the poor admin!

I know it's really terrible + juju is such a garbage service, just use standard orchestration tools

[@elmehdisaniss2347]

​@@MrRafu83 Ooh !! Why juju is such a garbage service ?!! I thought that it would be my tool of choice. Tell me about your experience with it pleaase !! 🙏

It's 2021. Ipv6 is a thing.

[@DrDingus]

shhh

[@s.i.m.c.a]

for local area network - ipv4 is a thing too. Moreover, a lot of providers still not offer ipv6 connectivity at all. Why to build ipv6/ipv4 bridges coz of that and catch lame edge cases?

It’s running on Ubuntu. That’s not bare metal. en.wikipedia.org/wiki/Bare_machine?wprov=sfti1
