ripta / tf_aws_centos_ami

Look up CentOS AMIs from your Terraform definitions

tf_aws_centos_ami

Terraform module to get CentOS AMIs, because CentOS doesn't publish the list anywhere publicly, and the "recommended" way to instantiate their images is through AWS MarketPlace.

This list is provided as-is, and I make no warranties about its validity or currency.

Input Variables

All input variables have default values, but we recommend specifying all of them:

• region, e.g., eu-central-1;
• release, e.g., 6.0 or 7.0; and
• virttype, e.g., hvm or pv.

All images are assumed to be x86-64.

Output Variable

There is only one output, named ami_id, which can be used directly on the ami_id attribute on aws_instance stanzas.

Example

module "centos_ami" {
  source = "github.com/ripta/tf_aws_centos_ami"
  region = "us-west-2"
  release = "7.0"
  virttype = "hvm"
}

resource "aws_instance" "web" {
  count = 5
  ami = "${module.centos_ami.ami_id}"
  instance_type = "m4.large"
}

Note

The process of updating amis.tf.json is painfully manual. You are welcome to submit a pull request to update said JSON. In the PR, please include the source URL, where you retrieved the AMI IDs, so that we can spot-check them.

If CentOS decides to publish a list of AMI IDs, PRs to automate this process is very much appreciated.
