Intro I have been experimenting a lot over the past 18 months with containers and in particular, Kubernetes, and one of the core things I always seemed to get hung up on was part-zero - creating the VMs to actually run K8s. I wanted a CLI only way to build a VM template for the OS and then deploy that to the cluster.
It turns out that with Ubuntu 18.04 LTS (in particular the cloud image OVA) there are a few things need changed from the base install (namely cloud-init) in order to make them play nice with OS Guest Customisation in vCenter....
I’ve been playing with cloud platforms quite a lot recently, and in particular Juju ↗’s way of operations caught my particular attention.
It has a very impressive feature set ↗ and makes deploying and linking “canned” apps very simple, whether you are using public, private or hybrid cloud instances.
I wanted to set Juju up with minimal fuss to give it a quick spin, obviously deploying OpenStack etc is a little more involved for a simple POC than I would have liked and using AWS/Azure/HP Cloud/MAAS was just way overkill....
It has, over the years always been quite a quandary to get SSO auth working from *nix -> MS AD without a huge amount of fiddling and tinkering, but there is a new auth framework in town by the name of realmd ↗. While tinkering with The Foreman ↗ recently it had dawned on me it would be cool to have it set up such that, after the VM had been automatically provisioned it would allow me to SSH into it using my AD credentials....
