terraform-aws-multi-az-subnets

what

• set minimum versions for providers without pinning to a specific major version

why

• the current method makes it very difficult to maintain or upgrade consistent provider versions within a project

references

https://www.terraform.io/docs/configuration/provider-requirements.html#best-practices-for-provider-versions

what

• Port (rewrite) module with 0.12 syntax
• Update Codefresh badge to point to the test pipeline in terraform-modules project
• Update examples
• Update README
• Update README examples

why

• Module currently does not work with 0.12
• Much easier syntax
• terraform-modules project contains pipelines for all terraform modules

what

• Return a map of AZs to subnet ARNs in the output

why

• Output map of AZs to subnet ARNs is useful for many use-cases

what

• updated README.yaml file
• add tags and categories
• rebuild README.md file

why

• need to add categories and tags so we can pull them into the documentation

what

• Remove tags in outputs

why

• Not needed, the output list is in order without using matchkey
• Produces count can't be computed error in top-level modules

what

• Fix private_route_count to honor the value of az_ngw_count

why

• Typo

what

• Regenerate README.md

why

• Previous version of build-harness has some typos

what

• Add README.yaml

why

• Standardize README

what

• Change outputs calculation to fix TF errors

why

• When NAT Gateways are not created (in private subnets) or when nat_gateway_enabled=false, Terraform throws error

Error: Error refreshing state: 1 error(s) occurred:

* module.private_subnets.output.az_ngw_ids: zipmap: count of keys (3) does not match count of values (0) in:

${zipmap(var.availability_zones, matchkeys(aws_nat_gateway.public.*.id, aws_nat_gateway.public.*.tags.AZ, var.availability_zones))}

• To address https://github.com/cloudposse/terraform-aws-multi-az-subnets/issues/2

test

what

• terraform-aws-multi-az-subnets implementation

why

• The module allows provisioning of private or public subnets in each provided Availability Zone, and then be able to find the subnet IDs by the AZ names
