Manual Deployment of the ACL Controller for Consul Service Mesh on AWS ECS (Elastic Container Service).

# Install the ACL Controller
|
||||
|
||||
This topic describes how to manually deploy the ACL controller to [automatically provision ACL tokens](/docs/ecs/architecture#automatic-acl-token-provisioning) for Consul on ECS.
|
||||
If you are using Terraform, refer to the [Terraform Secure Configuration](/docs/ecs/terraform/secure-configuration) page to deploy the ACL controller.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
* Your application tasks must include certain tags to be compatible with the ACL controller.
|
||||
Refer to the [Task Tags](/docs/ecs/manual/install#task-tags) section of the installation page.
|
||||
* You should be familiar with configuring Consul's secure features, including how to create ACL tokens and policies. Refer to the following [Learn Guides](https://learn.hashicorp.com/collections/consul/security) for an introduction and the [ACL system](/docs/security/acl) documentation for more information.
|
||||
|
||||
## Setup AWS Secrets Manager
|
||||
|
||||
The ACL controller supports managing secrets in AWS Secrets Manager.
|
||||
|
||||
Before deploying the ACL controller for the first time, you must [create the following secrets](https://docs.aws.amazon.com/secretsmanager/latest/userguide/manage_create-basic-secret.html) from Consul in AWS Secrets Manager.
|
||||
|
||||
| Secret | Initial Value | Sample Secret Name |
|
||||
| --------------------- | -------------- | ------------------------------ |
|
||||
| Consul server CA cert | Set | `my-consul-ca-cert` |
|
||||
| Bootstrap ACL Token | Set | `my-consul-bootstrap-token` |
|
||||
| Consul Client ACL Token | Empty | `<PREFIX>-consul-client-token` |
|
||||
|
||||
The secret for the client token must be intially empty. The ACL controller creates the client token in Consul
|
||||
and stores the token in Secrets Manager. In the secret name, `<PREFIX>` should be replaced with the
|
||||
[secret name prefix](/docs/ecs/manual/acl-controller#secret-name-prefix) of your choice.
|
||||
|
||||
### Secret Name Prefix
|
||||
|
||||
The ACL controller requires that the secrets it reads and writes are named with a unique prefix. The name prefix is used
|
||||
in the [Task Role Policy](/docs/ecs/manual/acl-controller#task-role-policy) to limit the ACL controller's access within
|
||||
AWS Secrets Manager to only those secrets strictly needed by the ACL controller.
|
||||
|
||||
The name prefix should be unique among secrets your AWS account. We recommend a short (8 character) random
|
||||
string for the prefix.
|
||||
|
||||
-> **NOTE:** If you are using the ACL controller with multiple ECS clusters, each cluster requires
|
||||
its own instance of the ACL controller, and each instance of the ACL controller should have a unique
|
||||
name prefix.
|
||||
|
||||
## Task Definition
|
||||
|
||||
You must create a task definition to deploy the ACL controller in your ECS cluster.
|
||||
The ACL controller must run in the same ECS cluster hosting your service mesh application
|
||||
tasks.
|
||||
|
||||
The following example shows how the task definition should be configured for the ACL controller.
|
||||
|
||||
```json
|
||||
{
|
||||
"family": "my-consul-acl-controller".
|
||||
"networkMode": "awsvpc",
|
||||
"containerDefinitions": [
|
||||
{
|
||||

|
||||
"-secret-name-prefix", "<PREFIX>",
|
||||
],
|
||||
"secrets": [
|
||||
{
|
||||
"name": "CONSUL_HTTP_TOKEN",
|
||||
"valueFrom": "arn:aws:secretsmanager:us-west-2:000000000000:secret:my-consul-bootstrap-token"
|
||||
},
|
||||
{
|
||||
"name": "CONSUL_CACERT_PEM",
|
||||
"valueFrom": "arn:aws:secretsmanager:us-west-2:000000000000:secret:my-consul-ca-cert"
|
||||
}
|
||||
],
|
||||
"environment": [
|
||||
{
|
||||
"name": "CONSUL_HTTP_ADDR",
|
||||
"value": "<Consul server HTTP API address>"
|
||||
}
|
||||
]
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
You must include the following top-level fields.
|
||||
|
||||
| Field name | Type | Description |

|
||||
| `environment` | string | Must set the `CONSUL_HTTP_ADDR` environment variable to the address of the HTTP API of your Consul servers. |
|
||||
|
||||
The following CLI options are required in the `command` field of the container definition.
|
||||
|
||||
| Flag | Type | Description |
|
||||
| --------------------------- | ------- | -------------------------------------------------------------------------------------------------------------------- |
|
||||
| `-consul-client-secret-arn` | string | The secret where the ACL controller will store the Consul client token. |
|
||||
| `-secret-name-prefix` | string | The [secret name prefix](/docs/ecs/manual/acl-controller#secret-name-prefix) that you chose for this ACL controller. |
|
||||
|
||||
## ECS Service
|
||||
|
||||
Once the task definition is created, define an ECS service in order to start an ACL controller task.
|
||||
|
||||
The following example contains the recommended settings for the ACL controller. Refer to
|
||||
the [ECS service](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/service_definition_parameters.html) documentation
|
||||
to complete the remaining details for your use case.
|
||||
|
||||
```json
|
||||
{
|
||||
"cluster": "<Your ECS cluster ARN>"
|
||||
"desiredCount": 1,
|
||||
"launchType": "FARGATE",
|
||||
"serviceName": "my-acl-controller",
|
||||
"taskDefinition": "<task definition ARN>",
|
||||
...
|
||||
}
|
||||
```
|
||||
|
||||
| Field name | Type | Description |
|
||||
| ---------------- | ------- | ---------------------------------------------------------------------------------------------------------------- |
|
||||
| `cluster` | string | Set to your ECS cluster name or ARN. This must be the same ECS cluster where your service mesh applications run. |
|
||||
| `desiredCount` | integer | Must be 1. Only one instance of the ACL controller should run per ECS cluster. |
|
||||
| `launchType` | string | Consul on ECS supports both the `FARGATE` and `EC2` launch types. |
|
||||
| `serviceName` | string | The service name of your choice. |
|
||||
| `taskDefinition` | string | Must be set to the ACL controller [task definition](/docs/ecs/manual/acl-controller#task-definition). |
|
||||
|
||||
## AWS IAM Roles
|
||||
|
||||
The ECS task and execution roles must be configured to allow the ACL controller access
|
||||
to the ECS API and Secrets Manager API.
|
||||
|
||||
### Task Role Policy
|
||||
|
||||
The following example shows the policy needed for the ECS task role for the ACL controller.
|
||||
This grants the ACL controller permission to list tasks, describe tasks, and read and update
|
||||
secrets.
|
||||
|
||||
```json
|
||||
{
|
||||
"Version": "2012-10-17",
|
||||
"Statement": [
|
||||
{
|
||||
"Effect": "Allow",
|
||||
"Action": [
|
||||
"ecs:ListTasks",
|
||||
"ecs:DescribeTasks"
|
||||
],
|
||||
"Resource": ["*"]
|
||||
},
|
||||
{
|
||||
"Effect": "Allow",
|
||||
"Action": [
|
||||
"secretsmanager:GetSecretValue",
|
||||
"secretsmanager:UpdateSecret"
|
||||
],
|
||||
"Resource": [
|
||||
"arn:aws:secretsmanager:us-west-2:000000000000:secret:<PREFIX>-*"
|
||||
]
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
The following are the required permissions. You will need to substitute `<PREFIX>` with your chosen [name prefix](/docs/ecs/manual/acl-controller#secret-name-prefix).
|
||||
|
||||
| Action | Resource | Description |
|
||||
| ------------------------------- | ----------------------------------------------------------------- | ---------------------------------------------------------------------------------- |
|
||||
| `ecs:ListTasks` | `*` | Allow the ACL controller to watch for new tasks. |
|
||||
| `ecs:DescribeTasks` | `*` | Allow the ACL controller to retrieve details for new tasks. |
|
||||
| `secretsmanager:GetSecretValue` | `arn:aws:secretsmanager:us-west-2:000000000000:secret:<PREFIX>-*` | Allow the ACL controller to read secrets with a name prefix. |
|
||||
| `secretsmanager:UpdateSecret` | `arn:aws:secretsmanager:us-west-2:000000000000:secret:<PREFIX>-*` | Allow the ACL controller to store Consul ACL tokens in secrets with a name prefix. |
|
||||
|
||||
### Execution Role Policy
|
||||
|
||||
The following IAM policy document allows ECS to retrieve secrets needed
|
||||
to start the ACL controller task from AWS Secrets Manager, including the ACL
|
||||
bootstrap token.
|
||||
|
||||
The following example shows the policy needed for the execution role.
|
||||
|
||||
```json
|
||||
{
|
||||
"Version": "2012-10-17",
|
||||
"Statement": [

Manual Secure Confguration of the Consul Service Mesh on AWS ECS (Elastic Container Service).

|

|
||||
# Secure Configuration
|
||||
|
||||
For a production-ready installation of Consul on ECS, you will need to make sure that the cluster is secured.
|
||||
A secure Consul cluster should include the following:
|
||||
|
||||
1. [TLS Encryption](/docs/security/encryption#rpc-encryption-with-tls) for RPC communication between Consul clients and servers.
|
||||
1. [Gossip Encryption](/docs/security/encryption#gossip-encryption) for encrypting gossip traffic.
|
||||
1. [Access Control (ACLs)](/docs/security/acl) for authentication and authorization for Consul clients and services on the mesh.
|
||||
|
||||
-> **NOTE:** This page assumes that you have already configured your Consul server with the above features.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
* You should already have followed the [installation instructions](/docs/ecs/manual/install) to understand how to define
|
||||
the necessary components of the task definition for Consul on ECS.
|
||||
* You should be familiar with [specifying sensitive data](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/specifying-sensitive-data.html) on ECS.
|
||||
* You should be familiar with configuring Consul's secure features, including how to create ACL tokens and policies. Refer to the following [Learn Guides](https://learn.hashicorp.com/collections/consul/security) for an introduction and the [ACL system](/docs/security/acl) documentation for more information.
|
||||
|
||||
## ACL Tokens
|
||||
|
||||
You must create two types of ACL tokens for Consul on ECS:
|
||||
|
||||
* **Client tokens:** used by the `consul-client` containers to join the Consul cluster
|
||||
* **Service tokens:** used by sidecar containers for service registration and health syncing
|
||||
|
||||
The following sections describe the ACL polices which must be associated with these token types.
|
||||
|
||||
-> **NOTE:** This section describes how operators would create ACL tokens by hand. To ease operator
|
||||
burden, the ACL Controller can automatically create ACL tokens for Consul on ECS. Refer to the
|
||||
[ACL Controller](/docs/manual/acl-controller) page for installation details.
|
||||
|
||||
### Create Consul client token
|
||||
|
||||
You must create a token for the Consul client. This is a shared token used by the `consul-client`
|
||||
containers to join the Consul cluster.
|
||||
|
||||
The following is the ACL policy needed for the Consul client token:
|
||||
|
||||
```hcl
|
||||
node_prefix "" {
|
||||
policy = "write"
|
||||
}
|
||||
service_prefix "" {
|
||||
policy = "read"
|
||||
}
|
||||
```
|
||||
|
||||
This policy allows `node:write` for any node name, which is necessary because the Consul node
|
||||
names on ECS are not known until runtime.
|
||||
|
||||
### Create service tokens
|
||||
|
||||
Service tokens should be associated with a [service identity](https://www.consul.io/docs/security/acl/acl-system#acl-service-identities).
|
||||
The service identity includes `service:write` permissions for the service and sidecar proxy.
|
||||
|
||||
The following example shows how to use the Consul CLI to create a service token for a service named `example-client-app`:
|
||||
|
||||
```shell
|
||||
consul acl token create -service-identity=example-client-app ...
|
||||
```
|
||||
|
||||
-> **NOTE**: You will need to create one service token for each registered Consul service in ECS,
|
||||
including when new services are added to the service mesh.
|
||||
|
||||
## Secret storage
|
||||
|
||||
You should securely store the following secrets in order to make them available to ECS tasks.
|
||||
|
||||
1. Consul Server CA certificate
|
||||
2. Consul gossip encryption key
|
||||
3. Consul client ACL token
|
||||
4. Consul service ACL tokens (one per service)
|
||||
|
||||
These secrets can be securely stored and passed to ECS tasks using either of the following AWS secret services:
|
||||
|
||||
* [AWS Systems Manager Parameter Store](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/specifying-sensitive-data-parameters.html)
|
||||
* [AWS Secrets Manager](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/specifying-sensitive-data-secrets.html)
|
||||
|
||||
Once the secrets are stored they can be referenced using their ARN. The following shows
|
||||
example secret ARNs when using AWS Secrets Manager:
|
||||
|
||||
| Secret | Sample Secret ARN |
|
||||
| ---------------------- | ---------------------------------------------------------------------------------- |
|
||||
| Consul Server CA Cert | `arn:aws:secretsmanager:us-west-2:000000000000:secret:my-consul-ca-cert` |
|
||||
| Gossip encryption key | `arn:aws:secretsmanager:us-west-2:000000000000:secret:my-consul-gossip-key` |
|
||||
| Client token | `arn:aws:secretsmanager:us-west-2:000000000000:secret:my-consul-client-token` |
|
||||
| Service token | `arn:aws:secretsmanager:us-west-2:000000000000:secret:my-example-client-app-token` |
|
||||
|
||||
## Configure `consul-client`
|
||||
|
||||
The following secrets must be passed to the `consul-client` container:
|
||||
|
||||
* Consul server CA certificate
|
||||
* Gossip encryption key
|
||||
* Consul client ACL token
|
||||
|
||||
The following example shows how to include these secrets in the task definition. The `secrets`

## Configure `consul-ecs-mesh-init` and `consul-ecs-health-sync`
|
||||
|

Both `consul-ecs-mesh-init` and `consul-ecs-health-sync` containers need to be configured with
|
||||
the service ACL token. This allows these containers to make HTTP API requests to the local
|
||||
Consul client for service registration and health syncing.
|
||||
|
||||
The following shows how to set the `CONSUL_HTTP_TOKEN` variable to the service token for the `example-client-app` service,
|
||||
if the token is stored in AWS Secrets Manager.
