# fastly_service_v1

Provides a Fastly Service, representing the configuration for a website, app,
API, or anything else to be served through Fastly. A Service encompasses Domains
and Backends.

The Service resource requires a domain name that is correctly set up to direct
traffic to the Fastly service. See Fastly's guide on [Adding CNAME Records][fastly-cname]
on their documentation site for guidance.

## Example Usage

Basic usage:

```hcl
resource "fastly_service_v1" "demo" {
  name = "demofastly"

  domain {
    name    = "demo.notexample.com"
    comment = "demo"
  }

  backend {
    address = "127.0.0.1"
    name    = "localhost"
    port    = 80
  }

  force_destroy = true
}
```

Basic usage with an Amazon S3 Website and that removes the `x-amz-request-id` header:

```hcl
resource "fastly_service_v1" "demo" {
  name = "demofastly"

  domain {
    name    = "demo.notexample.com"
    comment = "demo"
  }

  backend {
    address = "demo.notexample.com.s3-website-us-west-2.amazonaws.com"
    name    = "AWS S3 hosting"
    port    = 80
  }

  header {
    destination = "http.x-amz-request-id"
    type        = "cache"
    action      = "delete"
    name        = "remove x-amz-request-id"
  }

  gzip {
    name          = "file extensions and content types"
    extensions    = ["css", "js"]
    content_types = ["text/html", "text/css"]
  }

  default_host = "${aws_s3_bucket.website.name}.s3-website-us-west-2.amazonaws.com"

  force_destroy = true
}

resource "aws_s3_bucket" "website" {
  bucket = "demo.notexample.com"
  acl    = "public-read"

  website {
    index_document = "index.html"
    error_document = "error.html"
  }
}
```

Basic usage with [custom
VCL](https://docs.fastly.com/guides/vcl/uploading-custom-vcl) (must be
enabled on your Fastly account):

```hcl
resource "fastly_service_v1" "demo" {
  name = "demofastly"

  domain {
    name    = "demo.notexample.com"
    comment = "demo"
  }

  backend {
    address = "127.0.0.1"
    name    = "localhost"
    port    = 80
  }

  force_destroy = true

  vcl {
    name    = "my_custom_main_vcl"
    content = "${file("${path.module}/my_custom_main.vcl")}"
    main    = true
  }

  vcl {
    name    = "my_custom_library_vcl"
    content = "${file("${path.module}/my_custom_library.vcl")}"
  }
}
```

-> **Note:** For an AWS S3 Bucket, the Backend address is
`<domain>.s3-website-<region>.amazonaws.com`. The `default_host` attribute
should be set to `<bucket_name>.s3-website-<region>.amazonaws.com`. See the
Fastly documentation on [Amazon S3][fastly-s3].
