terraform-aws-ecr

Terraform module to provision an AWS ECR Docker Container registry.

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

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.

The module creates one or more Elastic Container Registry (ECR) repositories. All repositories created will share the same configuration. Use this module multiple times to create repositories with different configurations.

If you provide 1 or more names in image_names then one repository will be created for each of the names you provide. Those names can include "namespaces", which are just prefixes ending with a slash (/).

If you do not provide any names in image_names, the module will create a single ECR repo named namespace-stage-name or just name depending on the value of use_fullname.

Access to the repositories is granted to via the principals_full_access and principals_readonly_access lists, which are lists of strings that can designate any valid AWS Principal. This module only creates the Repository Policy allowing those Principals access. The Principals will still separately need IAM policies allowing them permission to execute ECR actions against the repository. For more details, see How Amazon Elastic Container Registry Works with IAM.

Include this repository as a module in your existing terraform code:

# IAM Role to be granted ECR permissions
data "aws_iam_role" "ecr" {
  name = "ecr"
}

module "ecr" {
  source                 = "git::https://github.com/cloudposse/terraform-aws-ecr.git?ref=master"
  namespace              = "eg"
  stage                  = "test"
  name                   = "ecr"
  principals_full_access = [data.aws_iam_role.ecr.arn]
}
