terraform-example-module

This is terraform-example-module project provides all the scaffolding for a typical well-built Cloud Posse module. It's a template repository you can use when creating new repositories.

---

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.

Here's how to invoke this example module in your projects

module "example" {
  source = "https://github.com/cloudposse/terraform-example-module.git?ref=master"
  example = "Hello world!"
}

Inputs

Name	Description	Type	Default	Required
additional_tag_map	Additional tags for appending to tags_as_list_of_maps. Not added to tags.	map(string)	{}	no
attributes	Additional attributes (e.g. 1)	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.	object({ enabled = bool namespace = string environment = string stage = string name = string delimiter = string attributes = list(string) tags = map(string) additional_tag_map = map(string) regex_replace_chars = string label_order = list(string) id_length_limit = number })	{ "additional_tag_map": {}, "attributes": [], "delimiter": null, "enabled": true, "environment": null, "id_length_limit": null, "label_order": [], "name": null, "namespace": null, "regex_replace_chars": null, "stage": null, "tags": {} }	no
delimiter	Delimiter to be used between namespace, environment, stage, name and attributes. Defaults to - (hyphen). Set to "" to use no delimiter at all.	string	null	no
enabled	Set to false to prevent the module from creating any resources	bool	null	no
environment	Environment, e.g. 'uw2', 'us-west-2', OR 'prod', 'staging', 'dev', 'UAT'	string	null	no
example	Example variable	string	"hello world"	no
id_length_limit	Limit id to this many characters. Set to 0 for unlimited length. Set to null for default, which is 0. Does not affect id_full.	number	null	no
label_order	The naming order of the id output and Name tag. Defaults to ["namespace", "environment", "stage", "name", "attributes"]. You can omit any of the 5 elements, but at least one must be present.	list(string)	null	no
name	Solution name, e.g. 'app' or 'jenkins'	string	null	no
namespace	Namespace, which could be your organization name or abbreviation, e.g. 'eg' or 'cp'	string	null	no
regex_replace_chars	Regex to replace chars with empty string in namespace, environment, stage and name. If not set, "/[^a-zA-Z0-9-]/" is used to remove all characters other than hyphens, letters and digits.	string	null	no
stage	Stage, e.g. 'prod', 'staging', 'dev', OR 'source', 'build', 'test', 'deploy', 'release'	string	null	no
tags	Additional tags (e.g. map('BusinessUnit','XYZ')	map(string)	{}	no

Outputs
