Terraform module to provision an [`AWS ECR Docker Container registry`](https://aws.amazon.com/ecr/).

> [!TIP]

> #### 👽 Use Atmos with Terraform

> Cloud Posse uses [`atmos`](https://atmos.tools) to easily orchestrate multiple environments using Terraform. 


> Works with [Github Actions](https://atmos.tools/integrations/github-actions/), [Atlantis](https://atmos.tools/integrations/atlantis), or [Spacelift](https://atmos.tools/integrations/spacelift).

>

> 

> Watch demo of using Atmos with Terraform

> Example of running atmos to manage infrastructure from our Quick Start tutorial.

## Usage

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](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_principal.html#Principal_specifying).

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](https://docs.aws.amazon.com/AmazonECR/latest/userguide/security_iam_service-with-iam.html).

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

```hcl

# 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.

## Inputs

| Name | Description | Type | Default | Required |

|------|-------------|------|---------|:--------:|

|  [additional\_tag\_map](#input\_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](#input\_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](#input\_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` | 
{
  "additional_tag_map": {},
  "attributes": [],
  "delimiter": null,
  "descriptor_formats": {},
  "enabled": true,
  "environment": null,
  "id_length_limit": null,

|  [descriptor\_formats](#input\_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
`{
   format = string
   labels = list(string)
}`
(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 be
identical to how they appear in `id`.
Default is `{}` (`descriptors` output will be empty). | `any` | `{}` | no |

|  [enable\_lifecycle\_policy](#input\_enable\_lifecycle\_policy) | Set to false to prevent the module from adding any lifecycle policies to any repositories | `bool` | `true` | no |

    encryption_type = string
    kms_key         = any

Does not affect `id_full`. | `number` | `null` | no |

|  [image\_names](#input\_image\_names) | List of Docker local image names, used as repository names for AWS ECR | `list(string)` | `[]` | no |

|  [image\_tag\_mutability](#input\_image\_tag\_mutability) | The tag mutability setting for the repository. Must be one of: `MUTABLE` or `IMMUTABLE` | `string` | `"IMMUTABLE"` | no |

|  [label\_key\_case](#input\_label\_key\_case) | Controls the letter case of the `tags` keys (label names) for tags generated by this module.
Does not affect keys of tags passed in via the `tags` input.
Possible values: `lower`, `title`, `upper`.
Default value: `title`. | `string` | `null` | no |

|  [label\_order](#input\_label\_order) | The order in which the labels (ID elements) appear in the `id`.
Defaults to ["namespace", "environment", "stage", "name", "attributes"].
You can omit any of the 6 labels ("tenant" is the 6th), but at least one must be present. | `list(string)` | `null` | no |

|  [label\_value\_case](#input\_label\_value\_case) | Controls the letter case of ID elements (labels) as included in `id`,
set as tag values, and output by this module individually.
Does not affect values of tags passed in via the `tags` input.
Possible values: `lower`, `title`, `upper` and `none` (no transformation).
Set this to `title` and set `delimiter` to `""` to yield Pascal Case IDs.
Default value: `lower`. | `string` | `null` | no |

|  [labels\_as\_tags](#input\_labels\_as\_tags) | Set of labels (ID elements) to include as tags in the `tags` output.
Default is to include all labels.
Tags with empty values will not be included in the `tags` output.
Set to `[]` to suppress all generated tags.
**Notes:**
  The value of the `name` tag, if included, will be the `id`, not the `name`.
  Unlike other `null-label` inputs, the initial setting of `labels_as_tags` cannot be
  changed in later chained modules. Attempts to change it will be silently ignored. | `set(string)` | [
  "default"
