This component is responsible for provisioning an ECS Cluster and associated load balancer.

Usage

Stack Level: Regional

Here's an example snippet for how to use this component.

The following will create

ecs cluster
load balancer with an ACM cert placed on example.com
r53 record on all *.example.com which will point to the load balancer

components:
  terraform:
    ecs:
      settings:
        spacelift:
          workspace_enabled: true
      vars:
        name: ecs
        enabled: true
        acm_certificate_domain: example.com
        route53_record_name: "*"
        # Create records will be created in each zone
        zone_names:
          - example.com
        capacity_providers_fargate: true
        capacity_providers_fargate_spot: true
        capacity_providers_ec2:
          default:
            instance_type: t3.medium
            max_size: 2

        alb_configuration:
          public:
            internal_enabled: false
            # resolves to *.public-platform.<environment>.<stage>.<tenant>.<domain>.<tld>
            route53_record_name: "*.public-platform"
            additional_certs:
              - "my-vanity-domain.com"
