## What

1. Update Version Pinning for Terraform to support 0.13

## Why

1. This is a relatively minor update that the CloudPosse module already likely supports.

0.13.0 enhancement for multiple repo creation

what

• Added variables and outputs to create multiple repositories in AWS ECR.

1. passing a list of docker images :
   list_image = ["redis", "nginx"]

2. then get a map of image name to the repository :
   repository_url_map = {
   "redis" = "xxx.dkr.ecr.eu-west-1.amazonaws.com/redis"
   "nginx = "xxx.dkr.ecr.eu-west-1.amazonaws.com/nginx "
   }

why

• it is convenient that if we could create multiple repositories at once by passing a list of docker images as an argument since AWS ECR assuming one repo per one docker image.
