terraform-aws-region-prompt

example for reproducing the issue as described in hashicorp/terraform#8680

(!) Please notice that the prompt for provider.aws.region will only occur if your ~./aws credential configuration is missing the entry for the default region. If not, Terraform may silently just read and use those credentials instead of the ones declared in the AWS provider.

known affected terraform versions 0.7.2, 0.7.3, 0.7.4, 0.7.5 and 0.7.6.

terraform.tfvars

you'll need to create your own terraform.tfvars file

aws_region = "us-east-1"
aws_access_key = "YOURACCESSKEY"
aws_secret_key = "YOURSECRETKEY"

working example (example1 folder)

open a bash shell and execute the following commands

cd example1
terraform get
terraform plan

you should get a execution plan as expected.

+ module.vpc.vpc.aws_vpc.vpc
    cidr_block:                "10.10.0.0/19"
    default_network_acl_id:    "<computed>"
    default_route_table_id:    "<computed>"
    default_security_group_id: "<computed>"
    dhcp_options_id:           "<computed>"

    enable_dns_support:        "true"

    main_route_table_id:       "<computed>"
    tags.%:                    "1"
    tags.Name:                 "terraform1-vpc"

failing example (example2 folder)

open a bash shell and execute the following commands

cd example2
terraform get
terraform plan

the plan will not run but the terraform AWS provider will ask for provider.aws.region

provider.aws.region
  The region where AWS operations will take place. Examples
  are us-east-1, us-west-2, etc.

  Default: us-east-1
