Terraform module to provision an AWS ECR Docker Container registry
.
Tip
Cloud Posse uses atmos
to easily orchestrate multiple environments using Terraform.
Works with Github Actions, Atlantis, or Spacelift.
Watch demo of using Atmos with Terraform
![](https://github.com/cloudposse/atmos/raw/master/docs/demo.gif?raw=true)
Example of running
atmos
to manage infrastructure from our Quick Start tutorial.
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 = "cloudposse/ecr/aws"
# Cloud Posse recommends pinning every module to a specific version
# version = "x.x.x"
namespace = "eg"
stage = "test"
name = "ecr"
principals_full_access = [data.aws_iam_role.ecr.arn]
}
Important
In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic approach for updating versions to avoid unexpected changes.

Name | Description | Type | Default | Required |
---|---|---|---|---|
additional_tag_map | Additional key-value pairs to add to each map in tags_as_list_of_maps . Not added to tags or id .This is for some rare cases where resources want additional configuration of tags and therefore take a list of maps with tag key, value, and additional configuration. |
map(string) |
{} |
no |
attributes | ID element. Additional attributes (e.g. workers or cluster ) to add to id ,in the order they appear in the list. New attributes are appended to the end of the list. The elements of the list are joined by the delimiter and treated as a single ID element. |
list(string) |
[] |
no |
context | Single object for setting entire context at once. See description of individual variables for details. Leave string and numeric variables as null to use default value.Individual variable settings (non-null) override settings in context object, except for attributes, tags, and additional_tag_map, which are merged. |
any |
{ |
no |
delimiter | Delimiter to be used between ID elements. Defaults to - (hyphen). Set to "" to use no delimiter at all. |
string |
null |
no |
descriptor_formats | Describe additional descriptors to be output in the descriptors output map.Map of maps. Keys are names of descriptors. Values are maps of the form {<br> format = string<br> labels = list(string)<br>} (Type is any so the map values can later be enhanced to provide additional options.)format is a Terraform format string to be passed to the format() function.labels is a list of labels, in order, to pass to format() function.Label values will be normalized before being passed to format() so they will beidentical to how they appear in id .Default is {} (descriptors output will be empty). |

true |
no |
enabled | Set to false to prevent the module from creating any resources | bool |
