Kubernetes basics online course
A little while ago I received an invite to attend an online workshop on SUSE’s Rancher product](https://www.rancher.com/products/rancher) at their “Rancher Academy”. Through that I discovered their Kubernetes Basics on demand course which I found gave a good introduction to Kubernetes at the level I needed - covering at a high-level what the various bits of it does before diving into how to make it do stuff.
