Alias
- class aws_cdk.aws_gamelift_alpha.Alias(scope, id, *, alias_name, description=None, fleet=None, terminal_message=None)
Bases:
AliasBase
(experimental) A Amazon GameLift alias is used to abstract a fleet designation.
Fleet designations tell GameLift where to search for available resources when creating new game sessions for players. Use aliases instead of specific fleet IDs to seamlessly switch player traffic from one fleet to another by changing the alias’s target location.
Aliases are useful in games that don’t use queues. Switching fleets in a queue is a simple matter of creating a new fleet, adding it to the queue, and removing the old fleet, none of which is visible to players. In contrast, game clients that don’t use queues must specify which fleet to use when communicating with the GameLift service. Without aliases, a fleet switch requires updates to your game code and possibly distribution of an updated game clients to players.
When updating the fleet-id an alias points to, there is a transition period of up to 2 minutes where game sessions on the alias may end up on the old fleet.

Example:
# fleet: gamelift.BuildFleet # Add an alias to an existing fleet using a dedicated fleet method live_alias = fleet.add_alias("live") # You can also create a standalone alias gamelift.Alias(self, "TerminalAlias", alias_name="terminal-alias", terminal_message="A terminal message" )
- Parameters:
scope (
Construct
) –id (
str
) –alias_name (
str
) – (experimental) Name of this alias.description (
Optional
[str
]) – (experimental) A human-readable description of the alias. Default: no descriptionfleet (
Optional
[IFleet
]) – (experimental) A fleet that the alias points to. If specified, the alias resolves to one specific fleet. At least one offleet
andterminalMessage
must be provided. Default: no fleet that the alias points to.terminal_message (
Optional
[str
]) – (experimental) The message text to be used with a terminal routing strategy. At least one offleet
andterminalMessage
must be provided. Default: no terminal message

Methods
- apply_removal_policy(policy)
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
).- Parameters:
policy (
RemovalPolicy
) –- Return type:
None
- to_string()
Returns a string representation of this construct.
- Return type:
str
Attributes
- alias_arn
(experimental) The ARN of the alias.
- Stability:
experimental
- alias_id
(experimental) The Identifier of the alias.
- Stability:
experimental
- env
The environment this resource belongs to.
For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.
- fleet
(experimental) A fleet that the alias points to.
- Stability:
experimental
- node
The tree node.
- resource_arn_for_destination
(experimental) The ARN to put into the destination field of a game session queue.
- Stability:
experimental
- stack
The stack in which this resource is defined.
Static Methods
- classmethod from_alias_arn(scope, id, alias_arn)
(experimental) Import an existing alias from its ARN.
- classmethod from_alias_attributes(scope, id, *, alias_arn=None, alias_id=None)
(experimental) Import an existing alias from its attributes.
- Parameters:
scope (
Construct
) –id (
str
) –alias_arn (
Optional
[str
]) – (experimental) The ARN of the alias. At least one ofaliasArn
andaliasId
must be provided. Default: derived fromaliasId
.alias_id (
Optional
[str
]) – (experimental) The identifier of the alias. At least one ofaliasId
andaliasArn
must be provided. Default: derived fromaliasArn
.
- Stability:
experimental
- Return type:
- classmethod from_alias_id(scope, id, alias_id)
(experimental) Import an existing alias from its identifier.
- classmethod is_construct(x)
Checks if
x
is a construct.Use this method instead of
instanceof
to properly detectConstruct
instances, even when the construct library is symlinked.Explanation: in JavaScript, multiple copies of the
constructs
library on disk are seen as independent, completely different libraries. As a consequence, the classConstruct
in each copy of theconstructs
library is seen as a different class, and an instance of one class will not test asinstanceof
the other class.npm install
will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of theconstructs
library can be accidentally installed, andinstanceof
will behave unpredictably. It is safest to avoid usinginstanceof
, and using this type-testing method instead.- Parameters:
x (
Any
) – Any object.- Return type:
bool
- Returns:
true if
x
is an object created from a class which extendsConstruct
.
- classmethod is_owned_resource(construct)
Returns true if the construct was created by CDK, and false otherwise.
- Parameters:
construct (
IConstruct
) –- Return type:
bool
- classmethod is_resource(construct)
Check whether the given construct is a Resource.
- Parameters:
construct (
IConstruct
) –- Return type:
bool
