Terraform-env-vars

The terraform-env-vars is a small script that receives on stdin the Terraform output in JSON format and from the command line the mapping from Terraform variable names to environment variable names.

Given the above inputs, it does two things:

• it validates the Terraform output against the mappings

  it displays errors and exits with 1 in case of failures

• it prints the list of environment variables on stdout

  the variables are separated by =, following the dotenv format

An example of EDN environment map:

{:terraform_db_user "PGUSER"
 :terraform_db_passaword "PGPASSWORD"}

You can also pass a JSON file by using the --json options:

{"terraform_db_user": "PGUSER",
 "terraform_db_passaword": "PGPASSWORD"}

Run terraform-env-vars --help for a help.

Usage

npm install -g @ep-npm/terraform-env-vars

cd a-terraform-dir/  # choose your Terraform deployment dir
terraform output -json | terraform-env-vars --edn env-vars.edn
...
PGUSER="..."
PGPASSWORD="..."
...
