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: We do not pin modules to versions in our examples because of the difficulty of keeping the versions in the documentation in sync with the latest released versions. We highly recommend that in your code you pin the version to the exact version you are using so that your infrastructure remains stable, and update versions in a systematic way so that they do not catch you by surprise.

Also, because of a bug in the Terraform registry (hashicorp/terraform#21417), the registry shows many of our inputs as required when in fact they are optional. The table below correctly indicates which inputs are required.

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]
}

Inputs

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`	{ "additional_tag_map": {}, "attributes": [], "delimiter": null, "descriptor_formats": {}, "enabled": true, "environment": null, "id_length_limit": null, "label_key_case": null, "label_order": [], "label_value_case": null, "labels_as_tags": [ "unset" ], "name": null, "namespace": null, "regex_replace_chars": null, "stage": null, "tags": {}, "tenant": null }	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 be identical to how they appear in `id`. Default is `{}` (`descriptors` output will be empty).	`any`	`{}`	no
enable_lifecycle_policy	Set to false to prevent the module from adding any lifecycle policies to any repositories	`bool`	`true`	no
enabled	Set to false to prevent the module from creating any resources	`bool`	`null`	no
encryption_configuration	ECR encryption configuration	object({ encryption_type = string kms_key = any })	`null`	no
environment	ID element. Usually used for region e.g. 'uw2', 'us-west-2', OR role 'prod', 'staging', 'dev', 'UAT'	`string`	`null`	no
force_delete	Whether to delete the repository even if it contains images	`bool`	`false`	no
id_length_limit	Limit `id` to this many characters (minimum 6). Set to `0` for unlimited length. Set to `null` for keep the existing setting, which defaults to `0`. Does not affect `id_full`.	`number`	`null`	no
image_names	List of Docker local image names, used as repository names for AWS ECR	`list(string)`	`[]`	no
image_tag_mutability	The tag mutability setting for the repository. Must be one of: `MUTABLE` or `IMMUTABLE`	`string`	`"IMMUTABLE"`	no
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	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	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	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" ]	no
max_image_count	How many Docker Image versions AWS ECR will store	`number`	`500`	no
name	ID element. Usually the component or solution name, e.g. 'app' or 'jenkins'. This is the only ID element not also included as a `tag`. The "name" tag is set to the full `id` string. There is no tag with the value of the `name` input.	`string`	`null`	no
namespace	ID element. Usually an abbreviation of your organization name, e.g. 'eg' or 'cp', to help ensure generated IDs are globally unique	`string`	`null`	no
principals_full_access	Principal ARNs to provide with full access to the ECR	`list(string)`	`[]`	no
principals_lambda	Principal account IDs of Lambdas allowed to consume ECR	`list(string)`	`[]`	no
principals_push_access	Principal ARNs to provide with push access to the ECR	`list(string)`	`[]`	no
principals_readonly_access	Principal ARNs to provide with readonly access to the ECR	`list(string)`	`[]`	no
protected_tags	Name of image tags prefixes that should not be destroyed. Useful if you tag images with names like `dev`, `staging`, and `prod`	`set(string)`	`[]`	no
regex_replace_chars	Terraform regular expression (regex) string. Characters matching the regex will be removed from the ID elements. If not set, `"/[^a-zA-Z0-9-]/"` is used to remove all characters other than hyphens, letters and digits.	`string`	`null`	no
scan_images_on_push	Indicates whether images are scanned after being pushed to the repository (true) or not (false)	`bool`	`true`	no
stage	ID element. Usually used to indicate role, e.g. 'prod', 'staging', 'source', 'build', 'test', 'deploy', 'release'	`string`	`null`	no
tags	Additional tags (e.g. `{'BusinessUnit': 'XYZ'}`). Neither the tag keys nor the tag values will be modified by this module.	`map(string)`	`{}`	no
tenant	ID element _(Rarely used, not included by default)_. A customer identifier, indicating who this instance of a resource is for	`string`	`null`	no
use_fullname	Set 'true' to use `namespace-stage-name` for ecr repository name, else `name`	`bool`	`true`	no
