README Header

Cloud Posse

Terraform module for generating or importing an SSH public key file into AWS.


This project is part of our comprehensive "SweetOps" approach towards DevOps.

Terraform Open Source Modules

It's 100% Open Source and licensed under the APACHE2.

We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!

Usage

IMPORTANT: The master branch is used in source just as an example. In your code, do not pin to master because there may be breaking changes between releases. Instead pin to the release tag (e.g. ?ref=tags/x.y.z) of one of our latest releases.

module "ssh_key_pair" {
  source                = "git::https://github.com/cloudposse/terraform-aws-key-pair.git?ref=master"
  namespace             = "eg"
  stage                 = "prod"
  name                  = "app"
  ssh_public_key_path   = "/secrets"
  generate_ssh_key      = "true"
  private_key_extension = ".pem"
  public_key_extension  = ".pub"
}

Makefile Targets

Available targets:

  help                                Help screen
