# Terraform STACKIT DNS Zone and Record Set Module
This module allows you to declaratively manage DNS zones and their associated record sets in STACKIT.
It supports:
- Creating one or more new DNS zones.
- Using pre-existing DNS zones by providing a `zone_id`.
- Creating one or more record sets within any managed zone.
## Usage Example
Here is an example of how to use the module to create one or many new zones and use another pre-existing one.
```terraform
terraform {
required_providers {
stackit = {
source = "stackitcloud/stackit"
version = "~> 0.59.0"
}
}
backend "s3" {
endpoints = {
s3 = "https://object.storage.eu01.onstackit.cloud"
}
bucket = "test-bucket"
key = "state/test/dns"
region = "eu01"
skip_region_validation = true
skip_metadata_api_check = true
skip_credentials_validation = true
skip_requesting_account_id = true
skip_s3_checksum = true
use_path_style = true
}
}
provider "stackit" {
# Configure your provider credentials, i.e.:
default_region = local.region
enable_beta_resources = true
service_account_key_path = "sa_key.json"
}
module "dns" {
source = "./path/to/your/module" # Or a Git URL git::https://commerce-platform.git.onstackit.cloud/commerce-platform-public//terraform-modules/dns
project_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
zones = {
# EXAMPLE 1: Create multiple zones with multiple A records
"primary_domain" = {
name = "first domain"
dns_name = "test-b.stackit.rocks"
record_sets = {
"qa-test" = {
name = "qa-test"
type = "A"
ttl = 3600
records = ["192.0.1.1", "192.0.1.2"]
}
"beta-test" = {
name = "beta-test"
type = "A"
ttl = 3600
records = ["192.0.2.10", "192.0.2.20", "192.0.2.30"]
}
}
},
"secondary_domain" = {
name = "second domain"
dns_name = "test-a.stackit.rocks"
record_sets = {
"alpha-records" = {
name = "alpha-test"
type = "A"
ttl = 3600
records = ["192.10.2.10", "192.10.2.20", "192.10.2.30"]
}
}
},
# EXAMPLE 2: Use a pre-existing zone and add a new TXT and A record to it
"existing_domain" = {
zone_id = "zzzzzzzz-zzzz-zzzz-zzzz-zzzzzzzzzzzz"
record_sets = {
"spf_txt" = {
name = "@"
type = "TXT"
records = ["v=spf1 mx -all"]
ttl = 7200
comment = "this is a test txt record"
},
"spf_cname" = {
name = "exampledomain"
type = "A"
ttl = 3600
records = ["192.0.29.1"]
}
}
},
# EXAMPLE 3: Create a new zone with no initial records
"empty_domain" = {
name = "My Empty Domain"
dns_name = "empty-example.com"
}
}
}
```

### Values for zones
| Key | Description | Type | Required |
| ----------------- | ------------------------------------------------------------------------------------------------------------------------------------------ | -------------- | ----------------------------------- |
| `zone_id` | The ID of an existing DNS zone to manage. If provided, the module will use the existing zone. If not provided, a new zone will be created. | `string` | Optional |
| `name` | The descriptive name of the DNS zone. | `string` | Optional |
| `dns_name` | The DNS name of the DNS zone. | `string` | Optional |
| `contact_email` | The contact email for the DNS zone. | `string` | Optional |
| `description` | A description of the DNS zone. | `string` | Optional |
| `acl` | The Access Control List (ACL) for the DNS zone. | `string` | Optional |
| `active` | Whether the DNS zone is active or not. | `bool` | Optional (currently non-functional) |
| `default_ttl` | The default Time-to-Live (TTL) for records in the DNS zone. | `number` | Optional |
| `expire_time` | The expiration time for the DNS zone. | `number` | Optional |
| `is_reverse_zone` | Whether the DNS zone is a reverse zone or not. | `bool` | Optional |
| `negative_cache` | The negative cache duration for the DNS zone. | `number` | Optional |
| `primaries` | A list of primary name servers for the DNS zone. | `list(string)` | Optional |
| `refresh_time` | The refresh time for the DNS zone. | `number` | Optional |
| `retry_time` | The retry time for the DNS zone. | `number` | Optional |
| `type` | The type of the DNS zone. Defaults to "primary" if not provided. | `string` | Optional |
### Values for record_sets
| Key | Description | Type | Required |
| --------- | ------------------------------------------------------------- | -------------- | ----------------------------------- |
| `name` | The name of the DNS record set. | `string` | Yes |
| `type` | The type of the DNS record set. | `string` | Yes |
| `records` | A list of DNS records for the record set. | `list(string)` | Yes |
| `ttl` | The Time-to-Live (TTL) for the DNS records in the record set. | `number` | Optional |
| `comment` | A comment for the DNS record set. | `string` | Optional |
| `active` | Whether the DNS record set is active or not. | `bool` | Optional (currently non-functional) |
## Outputs
| Name | Description |
| ------------- | ------------------------------------------------------------------------------------------ |
| `zones` | A map of all managed DNS zone objects, including those created and those referenced by ID. |
| `record_sets` | A map of all created DNS record set objects. |
## Notes
Setting a zone or record to inactive by using `active = false` is currently not possible due to a bug in the provider. It is active by default.

# Terraform Module: STACKIT Service Account
This module is designed to create a STACKIT service account, optionally generate a key, and optionally attach it to a server. It is useful for managing service accounts and their associated keys in a secure and repeatable manner.
The purpose of this module is to simplify the creation and management of service accounts in STACKIT, while providing flexibility to generate keys and attach them to servers. It also allows for secure storage of keys using a secrets manager.
## Example Usage
```terraform
module "service-account" {
source = "./service-account" # Or a Git URL "git::https://commerce-platform.git.onstackit.cloud/commerce-platform-public//terraform-modules/service-account"
stackit_project_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
service_account_name = "my-service-account"
service_account_create_key = true
}
# Save json created to secrets manager
variable "secret_manager_username" {
description = "username of the secrets manger to store credentials"
type = string
sensitive = true
}
variable "secret_manager_password" {
description = "password of the secrets manger to store credentials"
type = string
sensitive = true
}
module "service_account_key" {
source = "./create-secret" # Or a Git URL "git::https://commerce-platform.git.onstackit.cloud/commerce-platform-public//terraform-modules/create-secret"
secret_manager_instance_id = local.secret_manager_instance_id
secret_manager_username = var.secret_manager_username
secret_manager_password = var.secret_manager_password
secrets_path = "service-accounts/${module.service-account.service_account_name}"
secret_data = {
key_json = module.service-account.service_account_key_json
}
}
```
## Inputs
| Key | Description | Type | Required | Default |
| ------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------ | ------------- | -------- | ------- |
| `service_account_name` | Name of the service account | `string` | yes |
| `service_account_create_key` | Whether to create a service account key | `bool` | no | `false` |
| `service_account_public_key` | Optional: Specifies the public_key (RSA2048 key-pair). If not provided, a certificate from STACKIT will be used to generate a private_key. | `string` | no | `null` |
| `service_account_rotate_when_changed` | Map to force key rotation when changed | `map(string)` | no | `{}` |
| `service_account_ttl_days` | Key validity duration in days. Defaults to 90 | `number` | no | `90` |
| `attach_to_server` | Whether to attach the service account to a server | `bool` | no | `false` |
| `server_id` | Server ID for attachment | `string` | no | `""` |
## Notes
- When creating a key, it is recommended to save it securely using a secrets manager. In the example usage we illustrated how to do that using the `create-secret` module.
- The module does not handle key rotation automatically. You can use the service_account_rotate_when_changed input to force key rotation when certain attributes change.
- The module does not handle server attachment automatically. You can use the attach_to_server and server_id inputs to attach the service account to a server.
- The module does not handle deletion of service accounts or keys. It is recommended to manage these resources using appropriate Terraform lifecycle configurations or external tools.
