Example:

vpc = ec2.Vpc.from_lookup(self, "Vpc",
    is_default=True
)

cluster = ecs.Cluster(self, "Ec2Cluster", vpc=vpc)
cluster.add_capacity("DefaultAutoScalingGroup",
    instance_type=ec2.InstanceType("t2.micro"),
    vpc_subnets=ec2.SubnetSelection(subnet_type=ec2.SubnetType.PUBLIC)
)

task_definition = ecs.TaskDefinition(self, "TD",
    compatibility=ecs.Compatibility.EC2
)

task_definition.add_container("TheContainer",
    image=ecs.ContainerImage.from_registry("foo/bar"),
    memory_limit_mi_b=256
)

run_task = tasks.EcsRunTask(self, "Run",
    integration_pattern=sfn.IntegrationPattern.RUN_JOB,
    cluster=cluster,
    task_definition=task_definition,
    launch_target=tasks.EcsEc2LaunchTarget(
        placement_strategies=[
            ecs.PlacementStrategy.spread_across_instances(),
            ecs.PlacementStrategy.packed_by_cpu(),
            ecs.PlacementStrategy.randomly()
        ],
        placement_constraints=[
            ecs.PlacementConstraint.member_of("blieptuut")
        ]
    ),
    propagated_tag_source=ecs.PropagatedTagSource.TASK_DEFINITION
)
Parameters:

  • placement_constraints (Optional[Sequence[PlacementConstraint]]) – Placement constraints. Default: - None

  • placement_strategies (Optional[Sequence[PlacementStrategy]]) – Placement strategies. Default: - None
