vpc

Type: IVpc

VPC network of the fleet instances.

accessLoggingPolicy?

Type: AccessLoggingPolicyProperty (optional, default: disabled)

Enable Loadbalancer access logs Can be used to avoid manual work as aws console Required S3 bucket name , enabled flag Can add interval for pushing log Can set bucket prefix in order to provide folder name inside bucket.

Type: boolean (optional, default: true)

Whether cross zone load balancing is enabled.

This controls whether the load balancer evenly distributes requests across each availability zone

Type: HealthCheck (optional, default: None.)

Health check settings for the load balancing targets.

Not required but recommended.

---

internetFacing?

Type: boolean (optional, default: false)

Whether this is an internet-facing Load Balancer.

This controls whether the LB has a public IP address assigned. It does not open up the Load Balancer's security groups to public internet access.

---

listeners?

Type: LoadBalancerListener[] (optional, default: -)

What listeners to set up for the load balancer.

Can also be added by .addListener()

---

subnetSelection?

Type: SubnetSelection (optional, default: Public subnets if internetFacing, Private subnets otherwise)

Which subnets to deploy the load balancer.

Can be used to define a specific set of subnets to deploy the load balancer to. Useful multiple public or private subnets are covering the same availability zone.

---

targets?

Type: ILoadBalancerTarget[] (optional, default: None.)

What targets to load balance to.

Can also be added by .addTarget()
