# API Gateway
This module allows creating an API with its associated API config and API gateway. It also allows you grant IAM roles on the created resources.

# Examples

## Basic example
```hcl
module "gateway" {
  source     = "./fabric/modules/api-gateway"
  project_id = "my-project"
  api_id     = "api"
  region     = "europe-west1"
  spec       = <<EOT
  # The OpenAPI spec contents
  # ...
  EOT
}
# tftest modules=1 resources=4 inventory=basic.yaml
```

## Use existing service account
```hcl
module "gateway" {
  source                = "./fabric/modules/api-gateway"
  project_id            = "my-project"
  api_id                = "api"
  region                = "europe-west1"
  service_account_email = "sa@my-project.iam.gserviceaccount.com"
  iam = {
    "roles/apigateway.admin" = ["user:user@example.com"]
  }
  spec = <<EOT
  # The OpenAPI spec contents
  # ...
  EOT
}
# tftest modules=1 resources=7 inventory=existing-sa.yaml
```

## Create service account
```hcl
module "gateway" {
  source                 = "./fabric/modules/api-gateway"
  project_id             = "my-project"
  api_id                 = "api"
  region                 = "europe-west1"
  service_account_create = true
  iam = {
    "roles/apigateway.admin"  = ["user:mirene@google.com"]
    "roles/apigateway.viewer" = ["user:mirene@google.com"]
  }
  spec = <<EOT
  # The OpenAPI spec contents
  # ...
  EOT
}
# tftest modules=1 resources=11 inventory=create-sa.yaml
```
