Bases: BaseLoadBalancerProps

Properties for defining an Application Load Balancer.

Parameters:

vpc (IVpc) – The VPC network to place the load balancer in.
deletion_protection (Optional[bool]) – Indicates whether deletion protection is enabled. Default: false
internet_facing (Optional[bool]) – Whether the load balancer has an internet-routable address. Default: false
load_balancer_name (Optional[str]) – Name of the load balancer. Default: - Automatically generated name.
vpc_subnets (Union[SubnetSelection, Dict[str, Any], None]) – Which subnets place the load balancer in. Default: - the Vpc default strategy.
desync_mitigation_mode (Optional[DesyncMitigationMode]) – Determines how the load balancer handles requests that might pose a security risk to your application. Default: DesyncMitigationMode.DEFENSIVE
drop_invalid_header_fields (Optional[bool]) – Indicates whether HTTP headers with invalid header fields are removed by the load balancer (true) or routed to targets (false). Default: false
http2_enabled (Optional[bool]) – Indicates whether HTTP/2 is enabled. Default: true
idle_timeout (Optional[Duration]) – The load balancer idle timeout, in seconds. Default: 60
ip_address_type (Optional[IpAddressType]) – The type of IP addresses to use. Only applies to application load balancers. Default: IpAddressType.Ipv4
security_group (Optional[ISecurityGroup]) – Security group to associate with this load balancer. Default: A security group is created

infused

Example:

from aws_cdk.aws_autoscaling import AutoScalingGroup
# asg: AutoScalingGroup

# vpc: ec2.Vpc


# Create the load balancer in a VPC. 'internetFacing' is 'false'
# by default, which creates an internal load balancer.
lb = elbv2.ApplicationLoadBalancer(self, "LB",
    vpc=vpc,
    internet_facing=True
)

# Add a listener and open up the load balancer's security group
# to the world.
listener = lb.add_listener("Listener",
    port=80,

    # 'open: true' is the default, you can leave it out if you want. Set it
    # to 'false' and use `listener.connections` if you want to be selective
    # about who can access the load balancer.
    open=True
)

# Create an AutoScaling group and add it as a load balancing
# target to the listener.
listener.add_targets("ApplicationFleet",
    port=8080,
    targets=[asg]
)
