# IBuild

Your custom-built game server software that runs on GameLift and hosts game sessions for your players.

A game build represents the set of files that run your game server on a particular operating system.
You can have many different builds, such as for different flavors of your game.
The game build must be integrated with the GameLift service.
You upload game build files to the GameLift service in the Regions where you plan to set up fleets.

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/build.ts`](https://github.com/aws/aws-cdk/blob/v2.276.0-alpha.0/packages/@aws-cdk/aws-gamelift-alpha/lib/build.ts#L21)

## Properties

- `buildArn`: string — The ARN of the build.

- `buildId`: string — The Identifier of the build.

- `env`: [ResourceEnvironment](/cdk/api/v2/docs/aws-cdk-lib.interfaces.ResourceEnvironment.html) — The environment this resource belongs to.

  For resources that are created and managed in a Stack (those created by
  creating new class instances like `new Role()`, `new Bucket()`, etc.), this
  is always the same as the environment of the stack they belong to.

  For referenced resources (those obtained from referencing methods like
  `Role.fromRoleArn()`, `Bucket.fromBucketName()`, etc.), they might be
  different than the stack they were imported into.

- `grantPrincipal`: [IPrincipal](/cdk/api/v2/docs/aws-cdk-lib.aws_iam.IPrincipal.html) — The principal to grant permissions to.

- `node`: [Node](/cdk/api/v2/docs/constructs.Node.html) — The tree node.

- `stack`: [Stack](/cdk/api/v2/docs/aws-cdk-lib.Stack.html) — The stack in which this resource is defined.

## Methods

- `applyRemovalPolicy(policy: RemovalPolicy): void` — Apply the given removal policy to this resource.

  The Removal Policy controls what happens to this resource when it stops
  being managed by CloudFormation, either because you've removed it from the
  CDK application or because you've made a change that requires the resource
  to be replaced.

  The resource can be deleted (`RemovalPolicy.DESTROY`), or left in your AWS
  account for data recovery and cleanup later (`RemovalPolicy.RETAIN`).

- `with(...mixins: IMixin[]): IConstruct` — Applies one or more mixins to this construct.

  Mixins are applied in order. The list of constructs is captured at the
  start of the call, so constructs added by a mixin will not be visited.

  **Parameters**

  - `mixins` — The mixins to apply.

  **Returns:** This construct for chaining
