# AWS SSM Parameter Store Terraform module Terraform module which creates [AWS SSM Parameters](https://docs.aws.amazon.com/systems-manager/latest/userguide/systems-manager-parameter-store.html) on AWS. [![SWUbanner](https://raw.githubusercontent.com/vshymanskyy/StandWithUkraine/main/banner2-direct.svg)](https://github.com/vshymanskyy/StandWithUkraine/blob/main/docs/README.md) ## Available Features - One of multiple SSM Parameters can be created - Value type guesser - Allow SSM Parameter to ignore changes in the value - Wrapper module which allows managing multiple resources with less code ## Usage ### Parameter as String ```hcl module "string" { source = "terraform-aws-modules/ssm-parameter/aws" name = "my-parameter" value = "some-value" } ``` ### Parameter as SecureString ```hcl module "secret" { source = "terraform-aws-modules/ssm-parameter/aws" name = "my-secret-token" value = "secret123123!!!" secure_type = true } ``` ### Parameter as StringList ```hcl module "list" { source = "terraform-aws-modules/ssm-parameter/aws" name = "my-list-parameter" values = ["item1", "item2"] # "values" not "value" } ``` ### Parameter with ignored value changes ```hcl module "list" { source = "terraform-aws-modules/ssm-parameter/aws" ignore_value_changes = true name = "my-parameter-ignore-value-changes" value = "some-value" } ``` ### Multiple parameters ```hcl locals { parameters = { ######### # String ######### "string_simple" = { value = "string_value123" } "string" = { type = "String" value = "string_value123" tier = "Intelligent-Tiering" allowed_pattern = "[a-z0-9_]+" } ############### # SecureString ############### "secure" = { type = "SecureString" value = "secret123123!!!" tier = "Advanced" description = "My awesome password!" } "secure_encrypted_true" = { secure_type = true value = "secret123123!!!" key_id = "c938de44-1c09-4c91-89fd-b5881f06f317" } ############# # StringList ############# "list_as_autoguess_type" = { values = ["item1", "item2"] } "list_as_jsonencoded_string" = { type = "StringList" value = jsonencode(["item1", "item2"]) } "list_as_plain_string" = { type = "StringList" value = "item1,item2" } "list_as_autoconvert_values" = { type = "StringList" values = ["item1", "item2"] } "list_empty_as_jsonencoded_string" = { type = "StringList" value = jsonencode([]) } } } module "multiple" { source = "terraform-aws-modules/ssm-parameter/aws" for_each = local.parameters name = try(each.value.name, each.key) value = try(each.value.value, null) values = try(each.value.values, []) type = try(each.value.type, null) secure_type = try(each.value.secure_type, null) description = try(each.value.description, null) tier = try(each.value.tier, null) key_id = try(each.value.key_id, null) allowed_pattern = try(each.value.allowed_pattern, null) data_type = try(each.value.data_type, null) } ``` ## Module wrappers Users of this Terraform module can create multiple similar resources by using [`for_each` meta-argument within `module` block](https://www.terraform.io/language/meta-arguments/for_each) which became available in Terraform 0.13. Users of Terragrunt can achieve similar results by using modules provided in the [wrappers](https://github.com/terraform-aws-modules/terraform-aws-ssm-parameter/tree/master/wrappers) directory, if they prefer to reduce amount of configuration files. ## Examples - [Complete](https://github.com/terraform-aws-modules/terraform-aws-ssm-parameter/tree/master/examples/complete) - shows all possible ways to create parameters. ## Conditional Creation The following values are provided to toggle on/off creation of the associated resources as desired: ```hcl module "parameter" { source = "terraform-aws-modules/ssm-parameter/aws" # Disable creation of all resources create = false # ... omitted } ``` ## Requirements | Name | Version | | ---- | ------- | | [terraform](#requirement\_terraform) | >= 1.11 | | [aws](#requirement\_aws) | >= 6.28 | ## Providers | Name | Version | | ---- | ------- | | [aws](#provider\_aws) | >= 6.28 | ## Modules No modules. ## Resources | Name | Type | | ---- | ---- | | [aws_ssm_parameter.ignore_value](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/ssm_parameter) | resource | | [aws_ssm_parameter.this](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/ssm_parameter) | resource | ## Inputs | Name | Description | Type | Default | Required | | ---- | ----------- | ---- | ------- | :------: | | [allowed\_pattern](#input\_allowed\_pattern) | Regular expression used to validate the parameter value | `string` | `null` | no | | [create](#input\_create) | Whether to create SSM Parameter | `bool` | `true` | no | | [data\_type](#input\_data\_type) | Data type of the parameter. Valid values: `text`, `aws:ssm:integration` and `aws:ec2:image` for AMI format, see the [Native parameter support for Amazon Machine Image IDs](https://docs.aws.amazon.com/systems-manager/latest/userguide/parameter-store-ec2-aliases.html) | `string` | `null` | no | | [description](#input\_description) | Description of the parameter | `string` | `null` | no | | [ignore\_value\_changes](#input\_ignore\_value\_changes) | Whether to create SSM Parameter and ignore changes in value | `bool` | `false` | no | | [key\_id](#input\_key\_id) | KMS key ID or ARN for encrypting a `SecureString` | `string` | `null` | no | | [name](#input\_name) | Name of the parameter. If the name contains a path (e.g., any forward slashes (`/`)), it must be fully qualified with a leading forward slash (`/`) | `string` | `null` | no | | [overwrite](#input\_overwrite) | Overwrite an existing parameter. If not specified, defaults to `false` during create operations to avoid overwriting existing resources and then `true` for all subsequent operations once the resource is managed by Terraform | `bool` | `null` | no | | [region](#input\_region) | Region where the resource(s) will be managed. Defaults to the Region set in the provider configuration | `string` | `null` | no | | [secure\_type](#input\_secure\_type) | Whether the type of the value should be considered as secure or not | `bool` | `false` | no | | [tags](#input\_tags) | A map of tags to add to all resources | `map(string)` | `{}` | no | | [tier](#input\_tier) | Parameter tier to assign to the parameter. If not specified, will use the default parameter tier for the region. Valid tiers are Standard, Advanced, and Intelligent-Tiering. Downgrading an Advanced tier parameter to Standard will recreate the resource | `string` | `null` | no | | [type](#input\_type) | Type of the parameter. Valid types are `String`, `StringList` and `SecureString` | `string` | `null` | no | | [value](#input\_value) | Value of the parameter | `string` | `null` | no | | [value\_wo\_version](#input\_value\_wo\_version) | Value of the parameter. This value is always marked as sensitive in the Terraform plan output, regardless of type. Additionally, write-only values are never stored to state. `value_wo_version` can be used to trigger an update and is required with this argument | `number` | `null` | no | | [values](#input\_values) | List of values of the parameter (will be jsonencoded to store as string natively in SSM) | `list(string)` | `[]` | no | ## Outputs | Name | Description | | ---- | ----------- | | [insecure\_value](#output\_insecure\_value) | Insecure value of the parameter | | [raw\_value](#output\_raw\_value) | Raw value of the parameter (as it is stored in SSM). Use 'value' output to get jsondecode'd value | | [secure\_type](#output\_secure\_type) | Whether SSM parameter is a SecureString or not? | | [secure\_value](#output\_secure\_value) | Secure value of the parameter | | [ssm\_parameter\_arn](#output\_ssm\_parameter\_arn) | The ARN of the parameter | | [ssm\_parameter\_name](#output\_ssm\_parameter\_name) | Name of the parameter | | [ssm\_parameter\_type](#output\_ssm\_parameter\_type) | Type of the parameter | | [ssm\_parameter\_version](#output\_ssm\_parameter\_version) | Version of the parameter | | [value](#output\_value) | Parameter value after jsondecode().
