# This helps unblock me on following a long with materials for learning Ansible and Kubernetes
# locally, which rely on a VM service.
#
# I did not want to use VirtualBox, because on Linux it requires tainting the kernel. I also
# already have Docker installed and it's said to have better performance/less overhead.
#
# This Dockerfile will setup an Ubuntu container and configure it to support SSH, which is 
# required for testing Ansible locally with Vagrant.

/*
  If you try to do `keyof SomeType`, and `SomeType` has an interface of `[key: string]: x`
  TypeScript will infer that to a union of `string | number` because JavaScript coerces numeric 
  indexes to strings.  
  
  Example: obj[0] -> obj["0"]
  
  This can make it annoying to try to create an interface for interacting with one of these 
  types when we know we only want to accept string values, or that's a rule we want to enforce.
