Use Terraform to create an ECS cluster and deploy an application - Enterprise Distributed Application Service

You can use Terraform to create Elastic Compute Service (ECS) clusters and deploy applications in Enterprise Distributed Application Service (EDAS), bind Server Load Balancer (SLB) to the applications, create application groups, and scale out the applications. This topic provides information about available interfaces and a configuration example.

Interface description

Data Sources

alicloud_edas_applications: EDAS application data sources, including ECS applications and Container Service for Kubernetes (ACK) applications in EDAS.
alicloud_edas_clusters: EDAS cluster data sources, including ECS clusters and ACK clusters in EDAS.
alicloud_edas_deploy_groups: EDAS deploy groups data sources, which are the application groups of ECS applications in EDAS.

Resources

alicloud_edas_application: ECS application resource in EDAS.
alicloud_edas_application_deployment: deploys an ECS application in EDAS.
alicloud_edas_application_scale: scales out an ECS application in EDAS.
alicloud_edas_cluster: ECS cluster resource in EDAS.
alicloud_edas_deploy_group: the resource of an ECS application group in EDAS.
alicloud_edas_instance_cluster_attachment: scales out an ECS instance in an ECS cluster in EDAS.
alicloud_edas_slb_attachment: binds SLB to an ECS application in EDAS.

Configuration example

In the following example, an application is deployed in an ECS cluster in EDAS. Modify configuration parameters as needed.

Create an ECS cluster and add an ECS instance.

resource "alicloud_edas_cluster" "this" {
  cluster_name = var.cluster_name
  cluster_type = var.cluster_type
  network_mode = var.network_mode
  logical_region_id = var.logical_region_id
  vpc_id = var.vpc_id
}

resource "alicloud_edas_instance_cluster_attachment" "this" {
  cluster_id = alicloud_edas_cluster.this[count.index].id
  instance_ids = var.instance_ids
}

Create an application and bind SLB to the application.

resource "alicloud_edas_application" "this" {
  application_name  = var.application_name
  package_type      = var.package_type
  cluster_id        = var.cluster_id
  build_pack_id     = var.build_pack_id
  descriotion       = var.description
  health_check_url  = var.health_check_url
  logical_region_id = var.logical_region_id
  ecu_info          = var.ecu_info
  group_id          = var.group_id
  package_version   = var.package_version
  war_url           = var.war_url
}


resource "alicloud_edas_slb_attachment" "this" {
  app_id            = alicloud_edas_application.this[count.index].id
  slb_id            = var.slb_id
  slb_ip            = var.slb_ip
  type              = var.type
  listener_port     = var.listener_port
  vserver_group_id  = var.vserver_group_id
}

Create an application group and scale out the application.

resource "alicloud_edas_deploy_group" "this" {
  app_id      = var.app_id
  group_name  = var.group_name
}

resource "alicloud_edas_application_scale" "this" {
  app_id        = var.app_id
  deploy_group  = split(":", alicloud_edas_deploy_group.this[count.index].id)[2]
  ecu_info      = var.ecu_info
  force_status  = var.force_status
}


resource "null_resource" "delay" {
  provisioner "local-exec" {
    command = "sleep 5"
  }
  triggers = {
    "before" = "${join(",", alicloud_edas_application_scale.this.*.id)}"
  }
}

resource "alicloud_edas_application_deployment" "this" {
  depends_on = [
    alicloud_edas_application_scale.this,
  ]
  app_id          = var.app_id
  group_id        = split(":", alicloud_edas_deploy_group.this[count.index].id)[2]
  package_version = var.package_version
  war_url         = var.war_url
}
