This is not the certificate setup we will use in production. I'd like to
merge this configuration as a reference point because this is the
easiest way to handle manual LetsEncrypt verification within the
cluster.
This allows NGINX to serve static files over HTTP from the
".well-known/acme-challenge" directory, which is necessary for certbot
validation of domain ownership.
Adds a [kustomize](https://github.com/kubernetes-sigs/kustomize) overlay
for a new staging environment. Additionally, adds environment variables
in the place of certain pieces of information that need to be templated.
The K8s README ("deploy/README.md") has been updated to reflect the new
method for applying config.
This commit also removes the configuration for the AWS cluster and
references to AWS in the README.
With this configuration, all Kubernetes logs within the ATAT cluster
will be sent to AWS CloudWatch.
Note that this requires applying an additional IAM policy to the worker
nodes' role.
