# terraform-google-service-account-iam
A [Terraform](https://www.terraform.io) module to create a [Google Service Account IAM](https://cloud.google.com/iam/docs/service-accounts) on [Google Cloud Services (GCP)](https://cloud.google.com/).
**_This module supports Terraform version 1
and is compatible with the Terraform Google Provider version 4._** and 5._**
This module is part of our Infrastructure as Code (IaC) framework
that enables our users and customers to easily deploy and manage reusable,
secure, and production-grade cloud infrastructure.

## Module Features
This module implements the following terraform resources:
- `google_service_account_iam_binding`
- `google_service_account_iam_member`
- `google_service_account_iam_policy`
## Getting Started
Most basic usage just setting required arguments:
```hcl
module "terraform-google-service-account-iam" {
source = "github.com/mineiros-io/terraform-google-service-account-iam?ref=v0.1.0"
service_account_id = "my-service-account-id"
role = "roles/iam.serviceAccountUser"
members = ["user:[email protected]"]
}
```
## Module Argument Reference
See [variables.tf] and [examples/] for details and use cases.
### Top-level Arguments
#### Main Resource Configuration
- [**`service_account_id`**](#var-service_account_id): *(**Required** `string`)*
The fully-qualified name of the service account to apply the policy to.
- [**`members`**](#var-members): *(Optional `set(string)`)*
Identities that will be granted the privilege in the role. Each entry can have one of the following values:
- `allUsers`: A special identifier that represents anyone who is on the internet; with or without a Google account.
- `allAuthenticatedUsers`: A special identifier that represents anyone who is authenticated with a Google account or a service account.
- `user:{emailid}`: An email address that represents a specific Google account. For example, [email protected] or [email protected].
- `serviceAccount:{emailid}`: An email address that represents a service account. For example, [email protected].
- `group:{emailid}`: An email address that represents a Google group. For example, [email protected].
- `domain:{domain}`: A G Suite domain (primary, instead of alias) name that represents all the users of that domain. For example, google.com or example.com.
- `principalSet:{All identities in a group|All identities with a specific attribute value|All identities in a pool}`: Grants a role to all the identities in a workload identity pool, or to specific external identities based on their attributes. For details please see https://cloud.google.com/iam/docs/workload-identity-federation.
- `principal:{Single Identity}:` Grants a role to the specified identity in a workload identity pool. For details please see https://cloud.google.com/iam/docs/workload-identity-federation.
- `computed:{identifier}`: An existing key from var.computed_members_map.
Default is `[]`.
- [**`computed_members_map`**](#var-computed_members_map): *(Optional `map(string)`)*
A map of identifiers to identities to be replaced in 'var.members' or in members of `policy_bindings` to handle terraform computed values.
The format of each value must satisfy the format as described in `var.members`.
Default is `{}`.
- [**`role`**](#var-role): *(Optional `string`)*
The role that should be applied. Note that custom roles must be of the format `[projects|organizations]/{parent-name}/roles/{role-name}`.
- [**`authoritative`**](#var-authoritative): *(Optional `bool`)*
Whether to exclusively set (authoritative mode) or add (non-authoritative/additive mode) members to the role.
Default is `true`.
- [**`policy_bindings`**](#var-policy_bindings): *(Optional `list(policy_binding)`)*
A list of IAM policy bindings.
Example:
```hcl
policy_bindings = [{
role = "roles/viewer"
members = ["user:[email protected]"]
}]
```
Each `policy_binding` object in the list accepts the following attributes:
- [**`role`**](#attr-policy_bindings-role): *(**Required** `string`)*
The role that should be applied.
- [**`members`**](#attr-policy_bindings-members): *(Optional `set(string)`)*
Identities that will be granted the privilege in `role`.
Default is `var.members`.
- [**`condition`**](#attr-policy_bindings-condition): *(Optional `object(condition)`)*
An IAM Condition for a given binding.
Example:
```hcl
condition = {
expression = "request.time < timestamp(\"2022-01-01T00:00:00Z\")"
title = "expires_after_2021_12_31"
}
```
The `condition` object accepts the following attributes:
- [**`expression`**](#attr-policy_bindings-condition-expression): *(**Required** `string`)*
Textual representation of an expression in Common Expression Language syntax.
- [**`title`**](#attr-policy_bindings-condition-title): *(**Required** `string`)*
A title for the expression, i.e. a short string describing its purpose.
- [**`description`**](#attr-policy_bindings-condition-description): *(Optional `string`)*
An optional description of the expression. This is a longer text which describes the expression, e.g. when hovered over it in a UI.
#### Module Configuration
- [**`module_enabled`**](#var-module_enabled): *(Optional `bool`)*
Specifies whether resources in the module will be created.
Default is `true`.
- [**`module_depends_on`**](#var-module_depends_on): *(Optional `list(dependency)`)*
A list of dependencies. Any object can be _assigned_ to this list to define a hidden external dependency.
Example:
```hcl
module_depends_on = [
google_network.network
]
```
## Module Outputs
The following attributes are exported in the outputs of the module:
- [**`iam`**](#output-iam): *(`bool`)*
All attributes of the created `iam_binding` or `iam_member` or
`iam_policy` resource according to the mode.

## Module Versioning
This Module follows the principles of [Semantic Versioning (SemVer)].
Given a version number `MAJOR.MINOR.PATCH`, we increment the:
1. `MAJOR` version when we make incompatible changes,
2. `MINOR` version when we add functionality in a backward compatible manner, and
3. `PATCH` version when we make backward compatible bug fixes.
### Backwards compatibility in `0.0.z` and `0.y.z` version
- Backwards compatibility in versions `0.0.z` is **not guaranteed** when `z` is increased. (Initial development)
- Backwards compatibility in versions `0.y.z` is **not guaranteed** when `y` is increased. (Pre-release)
