Terraform module to define a consistent Hashicorp Cloud Platform Hashicorp Virtual Network in AWS.
This project is part of our comprehensive approach towards DevOps.
Designed following the Cloud Posse, LLC "SweetOps" approach.
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!
This is an introduction.
Security scanning provided by Bridgecrew. Bridgecrew is the leading fully hosted, cloud-native solution providing continuous Terraform security and compliance.
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.
For a complete example, see examples/complete.
For automated tests of the complete example using bats and Terratest (which tests and deploys the example on AWS), see test.
# Create a standard label resource. See [null-label](https://github.com/cloudposse/terraform-null-label/#terraform-null-label--)
module "label" {
source = "cloudposse/label/null"
# Cloud Posse recommends pinning every module to a specific version, though usually you want to use the current one
# version = "x.x.x"
namespace = "eg"
name = "example"
}
module "example" {
source = "ugns/hcp-hvn/aws"
# version = "x.x.x"
hvn_region = "us-east-1"
context = module.label.this
}

Name | Type |
---|---|
hcp_hvn.this | resource |
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). |
any |
{} |
no |
enabled | Set to false to prevent the module from creating any resources | bool |
null |
no |
environment | ID element. Usually used for region e.g. 'uw2', 'us-west-2', OR role 'prod', 'staging', 'dev', 'UAT' | string |
null |
no |
hvn_cidr_block | (Optional) The IPv4 CIDR block value enables communication between your HVN and VPCs. | string |
null |
no |
hvn_region | The AWS region where you want to deploy your HCP clusters. | string |
n/a | yes |
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 |
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 bechanged in later chained modules. Attempts to change it will be silently ignored. |
set(string) |
[ |
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 |
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 |
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 |
Name | Description |
---|---|
hcp_hvn_cidr_block | Hashicorp Cloud Platform CIDR block |
hcp_hvn_id | Hashicorp Cloud Platform HVN ID |
