AWS AMI SEARCH Terraform module

This terraform module finds the most recent AWS AMI for a specific linux distribution, optionally filtered by version and architecture.

Supported distributions:

• amazon (incomplete)
• debian (incomplete)
• fedora (incomplete)
• centos
• ubuntu
• rhel
• rocky
• suse (incomplete)

Supported architectures

• x86_64
• arm64

For distributions that do not use these exact architecture names, the module will map the name above to the whichever local naming scheme the distribution uses. Ie, if x86_64 is requested as the architecture for debian or one of its derivatives, the module will transparently map this to amd64.

Supported versions

Version support depends wholly on the distribution in question. See the source code for details.

Examples

module "ami-search" {
  source  = "terjekv/ami-search/aws"
  os = "rhel"
  os_version = "8" # optional, see variables.tf for defaults
  architecture = "arm64" # optional, defaults to x86_64
}

resource "aws_instance" "web" {
  ami = module.ami-search.ami_id
  instance_type = "t4g.micro"

  tags {
    Name = "HelloWorld"
  }
}

Limitations

• HVM type only (Hardcoded in the filter module)
• Ubuntu only accepts .04-releases.
• The user is responsible for matching the instance_type of the instance to the architecture of the ami.
• No windows support as of yet.

Terraform versions supported

Terraform 0.12 and later.

Thanks

The original repo has a PR with compatibility with Terraform >= 0.12 since September 2020 and not accepted. The original author seems not active on Github since 2019.

The updated repo added support for newer Terraforms.

This rewrite adds generic support for release identifiers and architecture support.
