Enterprise Only

Consul admin partitions is a feature of Consul Enterprise. The enterprise license is provided to you when HCP Consul deploys into your account. This tutorial deploys billable resources to your HashiCorp Cloud and AWS accounts.

Consul admin partitions let organizations define administrative boundaries for services using Consul. This helps organizations manage Consul as a global installation, with services hosted across many teams and business units. Teams benefit by managing and customizing their Consul environment in context to their workloads, without creating impact to other teams, or other Consul environments.

The following diagram shows the potential of Admin partitions within a single region. On the left, an organization works with many teams to support many individual, bespoke Consul clusters. On the right, the Consul cluster operates as a single unified server, with workloads registering into it via one, or many Consul client tenant clusters.

A picture of supporting multiple Consul Clusters. On the left, before using admin partition each cluster has its own server instances. On the right, many client clusters are supported by a single server cluster.

With admin partitions, teams do not need to share the responsibility of maintaining individual server clusters with the organization. These teams focus on contextually-relevant tasks and maintenance directly related to the business value they are delivering, such as service discovery and network automation. Organizations utilize the Consul server cluster as a unified control plane for this fleet of Consul client tenant instances.

Admin partitions creates a mechanism for teams to deploy and share services across their organization, and across other Consul client clusters. This automates the provisioning and registration of trusted Consul clients to a cluster. Admin partitions increases the velocity of a team's ability to deliver business value, eliminating the operational overhead of teams requesting resources from an organization. Admin partitions gives teams autonomy and agency, while the organization maintains control and support of the global Consul installation inside the organization.

In this tutorial, you will deploy HashiCups across two admin partitions, using HCP Consul and two Amazon Elastic Container Service (ECS) clusters, to Consul service mesh. Each ECS cluster is assigned to an admin partition, with HashiCups services hosted in both partitions. Configure HashiCups across partitions using Consul service mesh configuration entries to create the HashiCups deployment. Finish by verifying the services in Consul, then confirming the operation of HashiCups in your web browser.

Prerequisites

  • An Amazon Web Services (AWS) account with permission to deploy Amazon Elastic Container Service resources.
  • Access to AWS credentials to deploy resources via Terraform.
  • HashiCorp Cloud (HCP) Service Principal Credentials. Learn how to create Service Principals by reading the HCP Docs Service Principals documentation page.

Configure required project resources

Begin by cloning the repository.

$ git clone https://github.com/hashicorp-education/learn-consul-terraform

Navigate into the repository folder.

$ cd learn-consul-terraform

Fetch the tags from the remote git server to checkout the git tag for this tutorial.

$ git fetch --all --tags && git checkout tags/v0.6

Navigate into the project folder for this tutorial.

$ cd datacenter-deploy-ecs-hcp-ap

Set your HCP service principal credentials as environment variables.

$ export HCP_CLIENT_ID=YOUR_HCP_CLIENT_ID_GOES_HERE

$ export HCP_CLIENT_SECRET=YOUR_HCP_CLIENT_SECRET_GOES_HERE

Deploy required project resources

This tutorial begins by deploying an HCP Cluster, and two Amazon ECS clusters to deploy HashiCups across two ECS clusters. You will build upon this code, using Consul to set the admin partition for each tenant cluster. One partition (default) for private, internal services, another partition (part2) for public-facing services accessed via the internet. The default partition is assigned to HCP Consul, spanning HCP Consul, and one ECS Cluster, clust1. The part2 partition is assigned to ECS cluster, clust2. The following diagram will help you familiarize yourself with this architectural setup.

HashiCups represented in two Amazon ECS clusters, with HCP Consul as the Server instance

Note

Using Consul on ECS, admin partitions are assigned to individual ECS Clusters. An ECS cluster can belong to the default partition, but cannot be assigned to other partitions assigned to other Amazon ECS clusters.

Initialize the terraform project.

$ terraform init

Terraform has been successfully initialized!

# . . .

Deploy the initial resources for this tutorial to your AWS and HCP accounts, consisting of your HCP Consul Cluster, and two Amazon ECS clusters. Use terraform apply to deploy, which presents a confirmation screen to deploy the resources. Type “yes” to confirm the deployment of these resources.

$ terraform apply

Terraform will perform the following actions:

# . . .

Plan: 52 to add, 0 to change, 0 to destroy.

Do you want to perform these actions?
Terraform will perform the actions described above.
Only 'yes' will be accepted to approve.

Enter a value: yes

# . . .

Apply complete! Resources: 52 added, 0 changed, 0 destroyed.

The ECS mesh-task terraform submodule creates your application's ECS task definition, including Consul-specific configuration to register the task definition as both a Consul node, and service.

Create HashiCups infrastructure

Your HCP and AWS accounts currently include an HCP Consul cluster, and two Amazon ECS clusters. Continue on, building the Terraform code for the HashiCups application and surrounding infrastructure.

Create a file for the ACL controllers in the current project folder.

$ touch hashicups-acl_controllers.tf

Each ECS cluster and Consul partition uses an ACL controller to manage task access to HCP Consul. Create ACL Controllers for each ECS cluster, noting the highlights which enable partitions, and assigns each ACL controller to an ECS cluster and partition.

hashicups-acl_controllers.tf

module "acl_controller" {
  for_each = { for cluster in aws_ecs_cluster.clusters : cluster.name => cluster }
  source   = "registry.terraform.io/hashicorp/consul-ecs/aws//modules/acl-controller"
  version  = "0.4.1"
  log_configuration = {
    logDriver = var.ecs_ap_globals.cloudwatch_config.log_driver
    options = {
      awslogs-group         = aws_cloudwatch_log_group.acl_controllers[each.value.name].name
      awslogs-region        = var.region
      awslogs-stream-prefix = "${each.value.name}-${local.acl_prefixes.logs}"
      awslogs-create-group  = var.ecs_ap_globals.cloudwatch_config.create_groups
    }
  }
  subnets                           = module.vpc.private_subnets
  consul_server_http_addr           = hcp_consul_cluster.example.consul_public_endpoint_url
  consul_bootstrap_token_secret_arn = aws_secretsmanager_secret.bootstrap_token.arn
  region                            = var.region
  consul_partitions_enabled         = var.ecs_ap_globals.enable_admin_partitions.enabled
  consul_partition                  = each.value.name == local.clusters.one ? local.admin_partitions.one : local.admin_partitions.two
  ecs_cluster_arn                   = each.value.arn
  name_prefix                       = "${local.acl_base}-${each.value.name}"
}

Next, create the private and public task definitions for HashiCups using the mesh-task submodule.

The private task definitions in the first submodule block represent HashiCups services assigned to the default admin partition on ECS cluster, clust1. The consul_partition parameter for each mesh-task represent the admin partitions to which each group of tasks in mesh-task is being assigned. local.admin_partitions.one represents the default partitions on Amazon ECS cluster, clust1. local.admin_partitions.two represents the part2 partition on Amazon ECS cluster, clust2.

The tasks in each task definition group (public, and private) are created using by using the terraform-aws-consul-ecs mesh-task submodule, once for public, and once for private. To assign a task definition to an admin partition, the submodule uses parameters for the partition and namespace to assign the tasks to specified values.

Before creating the tutorial's task definitions, review the code sample below to observe the parameters in context of the submodule. To learn more, read the mesh-task usage docs on consul.io.

hashicups-tasks.tf

# This code block isn't intended for the tutorial, but as a reference point for the modules below.
module "hashicups-example-ecs-task-definition" {
  source                         = "registry.terraform.io/hashicorp/consul-ecs/aws//modules/mesh-task"
  version                        = "0.4.1"

  . . .

  consul_partition               = "partition-example-name"
  consul_namespace               = "namespace-consul-name"

  . . .

}

Create a file for these task definitions, in the current project folder.

Next, create data resources for each ECS task definition created from the mesh-task submodule. The data resources use metadata from their underlying ECS task definitions, mappingmesh-task task definitions to AWS ECS Service resources.

Insert the code below at the end of data.tf, in the current project folder.

data.tf

data "aws_ecs_task_definition" "public_tasks" {
  for_each = toset(local.tasks.public)
  task_definition = each.value

  depends_on = [module.hashicups-tasks-public]
}

data "aws_ecs_task_definition" "private_tasks" {
  for_each        = toset(local.tasks.private)
  task_definition = each.value

  depends_on = [module.hashicups-tasks-private]
}

data "consul_services" "all" {
  query_options {
    namespace = local.namespace
  }
  depends_on = [aws_ecs_service.public_services, aws_ecs_service.private_services]
}

data "consul_service" "each" {
  for_each = toset(concat(local.tasks.public, local.tasks.private))
  name = each.key
  query_options {
  wait_time = "1m"
  }
}

locals {
  tnames = {
    frontend = data.consul_service.each["frontend"].name
    payments = data.consul_service.each["payments"].name
    postgres = data.consul_service.each["postgres"].name
    public-api = data.consul_service.each["public-api"].name
    product-api = data.consul_service.each["product-api"].name
  }
}

Create the second admin partition

HCP Consul generates the default admin partition at the time of installation. Subsequent partitions are created by referencing a new partition name in a service configuration file, or by creating the partition resource via Consul cluster configuration. You will create the partition via Consul cluster configuration using Terraform. This partition, part2, consists of public-facing HashiCups services on ECS cluster, clust2.

Create a file for the admin partition in the current project folder.

$ touch consul-admin_partitions_part2.tf

Paste the code below, creating the part2 admin partition.

consul-admin_partitions_part2.tf

resource "consul_admin_partition" "partition-two" {
  name        = local.admin_partitions.two
  description = "Admin Partition for public facing HashiCups services"

  depends_on = [hcp_consul_cluster.example]
}

Create exported services

HashiCups services span two Amazon ECS Clusters, in different admin partitions. Consul's Exported Services feature defines which services can communicate outside its admin partition.

Create exported service entries for product-api and public-api. These two services communicate with each other in HashiCups.

Create a file for the exported services, in the current project folder.

$ touch consul-exported_services.tf

Insert the following code for product-api and public-api.

consul-exported_services.tf

resource "consul_config_entry" "export_product_api_to_part2" {
  kind      = "exported-services"
  name      = var.ecs_ap_globals.admin_partitions_identifiers.partition-one

          {
            Partition = consul_admin_partition.partition-two.name
          }
        ]
      }
    ]
  })
  depends_on = [aws_ecs_service.public_services]
}

resource "consul_config_entry" "export_public_api_to_default" {
  kind      = "exported-services"
  name      = consul_admin_partition.partition-two.name
  partition = consul_admin_partition.partition-two.name
  namespace = var.ecs_ap_globals.namespace_identifiers.global
  config_json = jsonencode({
    Services = [
      {
        Name = var.ecs_ap_globals.task_families.public-api
        Consumers = [
          {
            Partition = var.ecs_ap_globals.admin_partitions_identifiers.partition-one
          }
        ]
      }
    ]
  })
  depends_on = [aws_ecs_service.public_services]
}

Create service defaults

The product-api uses a service defaults configuration in Consul Service Mesh to declare its service protocol as a default global value.

Create a file for the service defaults, in the current project folder.

$ touch consul-service_defaults.tf

Paste the code below into consul-service_defaults.tf.

consul-service_defaults.tf

resource "consul_config_entry" "product-api" {
  kind = "service-defaults"
  name = data.consul_service.each["product-api"].name

  config_json = jsonencode({
    Protocol = local.consul_service_defaults_protocols.tcp
  })
}

Create service intentions

Service intentions permit access between source and destination services in the Consul service mesh. Create service intentions for services which communicate with each other in the HashiCups application.

Create a file for the service intentions, in the current project folder.

$ touch consul-service_intentions.tf

Paste the code below, into consul-service_intentions.tf.

consul-service_intentions.tf

Create HashiCups Amazon ECS services

To deploy HashiCups, each mesh-task definition operates as an Amazon ECS Service. The aws_ecs_service terraform resource creates the deployment for the task definition. When the ECS service finishes deploying, each task definition is represented in ECS as an active task. In HCP Consul each active task is represented as a service in Consul service mesh, and as a node in the Consul cluster.

Create a file for the ECS Services, in the current project folder.

$ touch hashicups-ecs-services.tf

Place the code into the file.

hashicups-ecs-services.tf

resource "aws_ecs_service" "private_services" {
  for_each = data.aws_ecs_task_definition.private_tasks

  desired_count          = 1
  enable_execute_command = true
  cluster                = aws_ecs_cluster.clusters[local.clusters.one].arn
  launch_type            = local.launch_fargate
  propagate_tags         = local.service_tag
  name                   = each.value.family
  task_definition        = each.value.arn
  network_configuration {
    subnets          = module.vpc.private_subnets
    security_groups  = [aws_security_group.example_client_app_alb.id]
    assign_public_ip = false
  }
}

resource "aws_ecs_service" "public_services" {
  for_each = data.aws_ecs_task_definition.public_tasks

  desired_count          = 1
  enable_execute_command = true
  cluster                = aws_ecs_cluster.clusters[local.clusters.two].arn
  launch_type            = local.launch_fargate
  propagate_tags         = local.service_tag
  name                   = each.value.family
  task_definition        = each.value.arn
  network_configuration {
    assign_public_ip = true
    subnets          = module.vpc.private_subnets
    security_groups  = [aws_security_group.example_client_app_alb.id]
  }
  dynamic "load_balancer" {
    # Only configure load balancing targets for tasks that require it, namely, any entity present in the local.entities list that filters the required tasks.
    # The for_each evaluates true when the container name and task definition match each other.
    for_each = { for e in local.load_balancer_public_apps_config : e.container_name => e if each.value.task_definition == e.container_name }
    content {
      container_name   = each.value.task_definition
      container_port   = load_balancer.value.container_port
      target_group_arn = load_balancer.value.target_group
    }
  }
}

Create an outputs file, in the current project folder.

$ touch outputs.tf

You will create ouputs from the deployed resources to log in to HCP Consul, and observe the HashiCups application in a web browser.

Place the following code in outputs.tf.

output "outputs_sensitive" {
  value = {
    consul_bootstrap_token = hcp_consul_cluster.example.consul_root_token_secret_id
  }
  sensitive = true
}

output "outputs_not_sensitive" {
  value = {
    consul_ui_address = hcp_consul_cluster.example.consul_public_endpoint_url
    hashicups_url = "http://${aws_lb.example_client_app.dns_name}"
  }
}

Using terraform apply, deploy the HashiCups application and related configuration.

$ terraform apply

Plan: 66 to add, 0 to change, 0 to destroy.

Do you want to perform these actions?
  Terraform will perform the actions described above.  Only 'yes' will be accepted to approve.
  Enter a value: yes

# . . .

Apply complete! Resources: 66 added, 0 changed, 0 destroyed.

Outputs:

outputs_not_sensitive = {
  "consul_ui_address" = "https://dc1-uO0.consul.223350f5-f0b9-4d89-959d-aa8eab3184e5.aws.hashicorp.cloud"  "hashicups_url" = "http://ap-1445958408.us-east-1.elb.amazonaws.com"}

outputs_sensitive = <sensitive>

Validate services

Using terraform output, retrieve the login token in your shell. Copy the HCP Consul URL in thevalue.consul_ui_address stanza of the json output.

$ terraform output -json

{
  "outputs_not_sensitive": {
    "sensitive": false,
    "type": [
      "object",
      {
        "consul_ui_address": "string",
        "hashicups_url": "string"
      }
    ],
    "value": {
      "consul_ui_address": "https://dc1-VwY.consul.223350f5-f0b9-4d89-959d-aa8eab3184e5.aws.hashicorp.cloud",
      "hashicups_url": "http://ap-1741556077.us-east-1.elb.amazonaws.com"
    }
  },
  "outputs_sensitive": {
    "sensitive": true,
    "type": [
      "object",
      {
        "consul_bootstrap_token": "string"
      }
    ],
    "value": {
      "consul_bootstrap_token": "5e157744-d58f-bffb-c403-8bf896e9d8fe"
    }
  }
}

Navigate to the Consul UI URL in your browser. Log in with the token.

Visit HashiCups application

Next, navigate to the HashiCups URL in your browser. Retrieve the URL with terraform output. Copy the value in the outputs_not_sensitive.value.hashicups_url stanza of your json output.

$ terraform output outputs_not_sensitive -json

{
  "outputs_not_sensitive": {
    "sensitive": false,
    "type": [
      "object",
      {
        "consul_ui_address": "string",
        "hashicups_url": "string"
      }
    ],
    "value": {
      "consul_ui_address": "https://dc1-VwY.consul.223350f5-f0b9-4d89-959d-aa8eab3184e5.aws.hashicorp.cloud",
      "hashicups_url": "http://ap-1741556077.us-east-1.elb.amazonaws.com"
    }
  }
}

HashiCups home page

When the page loads, the HashiCups application renders on-screen, with a collection of beverages to choose from, for (fictional) purchase. This confirms HashiCups services are communicating across partitions, across Amazon ECS clusters. This concludes the tutorial.

Clean up

Bring down the infrastructure using terraform destroy.

$ terraform destroy -auto-approve

The clean-up process takes up to 20 minutes.

Next steps

In this tutorial, you deployed HCP Consul, two Amazon ECS clusters, HashiCups tasks as services deployed to Consul on ECS. These clusters comprised of services deployed across admin partitions, in individual Amazon ECS clusters. To learn more, take the following tutorials and read the docs to learn more about Amazon ECS at HashiCorp, and Consul admin partitions.
