Since this resource produces a list it feels more intuitive to give its
attribute a plural name, and since the noun "instance" already means
something specific in the AWS provider that doesn't apply here we use
"names" to indicate that these are availability zone names.
Also includes updating the docs to not show a dynamic count example for
now, since we don't support that yet.
This brings over the work done by @apparentlymart and @radeksimko in
PR #3124, and converts it into a data source for the AWS provider:
This commit adds a helper to construct IAM policy documents using
familiar Terraform concepts. It makes Terraform-style interpolations
easier and resolves the syntax conflict between Terraform interpolations
and IAM policy variables by changing the latter to use &{...} for its
interpolations.
Its use is completely optional and users are free to go on using literal
heredocs, file interpolations or whatever else; this just adds another
option that fits more naturally into a Terraform config.
This data source allows one to look up the most recent AMI for a specific
set of parameters, much like aws ec2 describe-images in the AWS CLI.
Basically a refresh of hashicorp/terraform#4396, in data source form.
This commit adds a data source with a single list, `instance` for the
schema which gets populated with the availability zones to which an
account has access.
