# Requirements for Consul on AWS Elastic Container Service (ECS)
|
|
|
|
The following requirements must be met in order to install Consul on ECS:
|
|
|
|
* **Launch Type:** Fargate and EC2 launch types are supported.
|
|
* **Network Mode:** Only `awsvpc` mode is supported.
|
|
* **Subnets:** ECS Tasks can run in private or public subnets. Tasks must have [network access](https://aws.amazon.com/premiumsupport/knowledge-center/ecs-pull-container-api-error-ecr/) to Amazon ECR or other public container registries to pull images.
|
|
* **Consul Servers:** You can use your own Consul servers running on virtual machines or use [HashiCorp Cloud Platform Consul](https://www.hashicorp.com/cloud-platform) to host the servers for you. For development purposes or testing, you may use the `dev-server` [Terraform module](https://github.com/hashicorp/terraform-aws-consul-ecs/tree/main) that runs the Consul server as an ECS task. The `dev-server` does not support persistent storage.
|
|
* **ACL Controller:** If you are running a secure Consul installation with ACLs enabled, configure the ACL controller.
|
|
* **Admin Partitions:** <EnterpriseAlert inline />Consul on ECS supports [admin partitions](/docs/enterprise/admin-partitions) when ACLs are enabled and the ACL controller is configured.
|
|
The ACL controller manages one admin partition and each ECS cluster requires an ACL controller.
|
|
Each `mesh-task` must also be configured to use a Consul Enterprise client.
|
|
* **Namespaces:** <EnterpriseAlert inline />[Namespaces](/docs/enterprise/namespaces) are supported when ACLs are enabled and the ACL controller is configured.
|
|
Each `mesh-task` must also be configured to use a Consul Enterprise client.
|
|
* **Sidecar containers:** Consul on ECS requires two sidecar containers to run in each ECS task: a
|
|
Consul agent container and a sidecar proxy container. These additional sidecar containers must
|
|
be included in the ECS task definition. The [Consul ECS Terraform module](/docs/ecs/terraform/install)
|
|
will include these sidecar containers for you. If you do not use Terraform, you can construct
|
|
the task definition yourself by following [our documentation](/docs/ecs/manual/install).
|
|
* **Routing:** With your application running in tasks as part of the mesh, you must specify the
|
|
upstream services that your application calls. You will also need to change the URLs your
|
|
application uses to ensure the application is making requests through the service mesh.
|
|
* **Bind Address:** Once all communication is flowing through the service mesh, you should change
|
|
the address your application is listening on to `127.0.0.1` so that it only receives requests
|
|
through the sidecar proxy.
