Module: ecr

Terraform module to provision an AWS ECR Docker Container registry.

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. 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

NameDescriptionTypeDefaultRequired
additional_tag_mapAdditional 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
attributesID 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
contextSingle 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.

no
delimiterDelimiter to be used between ID elements.
Defaults to - (hyphen). Set to "" to use no delimiter at all.
stringnullno
descriptor_formatsDescribe 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).

id_length_limitLimit 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.

image_tag_mutabilityThe tag mutability setting for the repository. Must be one of: MUTABLE or IMMUTABLEstring"IMMUTABLE"no
label_key_caseControls 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.
stringnullno
label_orderThe 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)nullno
label_value_caseControls 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.
stringnullno
labels_as_tagsSet 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.

nameID element. Usually the component or solution name, e.g. 'app' or 'jenkins'.

The "name" tag is set to the full id string. There is no tag with the value of the name input.
