Terraform module to create an ECS Service for a web app (task), and an ALB target group to route requests.
This project is part of our comprehensive "SweetOps" approach towards DevOps.
It's 100% Open Source and licensed under the APACHE2.
We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!

module "label" {
source = "git::https://github.com/cloudposse/terraform-terraform-label.git?ref=master"
namespace = "eg"
stage = "staging"
name = "app"
}
module "container_definition" {
source = "git::https://github.com/cloudposse/terraform-aws-ecs-container-definition.git?ref=master"
container_name = "app"
container_image = "cloudposse/geodesic:latest"
environment = [
{
name = "string_var"
value = "I am a string"
},
{
name = "true_boolean_var"
value = true
},
{
name = "false_boolean_var"
value = false
},
{
name = "integer_var"
value = 42
},
]
port_mappings = [
{
containerPort = 8080
hostPort = 80
protocol = "tcp"
},
{
containerPort = 8081
hostPort = 443
protocol = "udp"
},
]
}
module "alb_service_task" {
source = "git::https://github.com/cloudposse/terraform-aws-ecs-alb-service-task.git?ref=master"
namespace = "eg"
stage = "staging"
name = "app"
alb_target_group_arn = "xxxxxxx"
container_definition_json = "${module.container_definition.json}"
container_name = "${module.label.id}"
ecs_cluster_arn = "xxxxxxx"
launch_type = "FARGATE"
vpc_id = "xxxxxxx"
security_group_ids = ["xxxxx", "yyyyy"]
private_subnet_ids = ["xxxxx", "yyyyy", "zzzzz"]
}
The container_image
in the container_definition
module is the Docker image used to start a container.
This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default.
Other repositories are specified with either repository-url/image:tag
or repository-url/image@digest
.
Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed.
This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run
.
When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image are not propagated to already running tasks.
Images in Amazon ECR repositories can be specified by either using the full registry/repository:tag
or registry/repository@digest
.
For example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest
or 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE
.
Images in official repositories on Docker Hub use a single name (for example, ubuntu
or mongo
).
Images in other repositories on Docker Hub are qualified with an organization name (for example, amazon/amazon-ecs-agent
).
Images in other online repositories are qualified further by a domain name (for example, quay.io/assemblyline/ubuntu
).
