Terraform AWS credentials file not found

To get multiple profiles to work with Terraform make sure that you supply the

aws_access_key_id 

piece to your profile declaration. Each profile should look like this:

[profile_name]
aws_access_key=*****
aws_secret_access_key****
aws_access_key_id=*****

Technically you don't even need the aws_access_key as it seems the id version is what the underlying aws cli needs. Maybe it was me, but that was never clear in the documents I read.

I tested with Terraform v0.6.15 and its working fine.

Issue must be with the profile. Check the following.

1. Remove 2 profile tags from your provider.

provider "aws" {
  region  = "${var.region}"
  shared_credentials_file = "/Users/david/.aws/credentials"
  profile = "testing"
}

2. Make sure your credentials file /Users/david/.aws/credentials is in the below format, where testing is the profile you are specifying in provider "aws"

[testing]
aws_access_key_id = *****
aws_secret_access_key = *****
