# Amazon ECS Cluster Terraform Module
|
||||
|
||||
Terraform module which creates Amazon ECS (Elastic Container Service) cluster resources on AWS.
|
||||
|
||||
## Available Features
|
||||
|
||||
- ECS cluster
|
||||
- Fargate capacity providers
|
||||
- EC2 AutoScaling Group capacity providers
|
||||
- ECS Service w/ task definition, task set, and container definition support
|
||||
|
||||
For more details see the [design doc](https://github.com/terraform-aws-modules/terraform-aws-ecs/blob/master/docs/README.md)
|
||||
|
||||
## Usage
|
||||
|
||||
### Fargate Capacity Providers
|
||||
|
||||
```hcl
|
||||
module "ecs_cluster" {
|
||||
source = "terraform-aws-modules/ecs/aws//modules/cluster"
|
||||
|
||||
cluster_name = "ecs-fargate"
|
||||
|
||||
cluster_configuration = {
|
||||
execute_command_configuration = {
|
||||
logging = "OVERRIDE"
|
||||
log_configuration = {
|
||||
cloud_watch_log_group_name = "/aws/ecs/aws-ec2"
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
fargate_capacity_providers = {
|
||||
FARGATE = {
|
||||
default_capacity_provider_strategy = {
|
||||
weight = 50
|
||||
}
|
||||
}
|
||||
FARGATE_SPOT = {
|
||||
default_capacity_provider_strategy = {
|
||||
weight = 50
|
||||
}
|
||||
}
|

}
|
||||
|
||||
tags = {
|
||||
Environment = "Development"
|
||||
Project = "EcsEc2"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### EC2 Autoscaling Capacity Providers
|
||||
|
||||
```hcl
|
||||
module "ecs_cluster" {
|
||||
source = "terraform-aws-modules/ecs/aws//modules/cluster"
|
||||
|

|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Conditional Creation
|
||||
|
||||
The following values are provided to toggle on/off creation of the associated resources as desired:
|
||||
|
||||
```hcl
|
||||
module "ecs_cluster" {
|
||||
source = "terraform-aws-modules/ecs/aws//modules/cluster"
|
||||
|
||||
# Disable creation of cluster and all resources
|
||||
create = false
|
||||
|
||||
# ... omitted
|
||||
}
|
||||
```
|
||||
|
||||

# Amazon ECS Container Definition Module
|
||||
|
||||
Configuration in this directory creates an Amazon ECS container definition.
|
||||
|
||||
The module defaults to creating and utilizing a CloudWatch log group. You can disable this behavior by setting `enable_cloudwatch_logging` = `false` - useful for scenarios where Firelens is used for log forwarding.
|
||||
|
||||
For more details see the [design doc](https://github.com/terraform-aws-modules/terraform-aws-ecs/blob/master/docs/design.md)
|
||||
|
||||
## Usage
|
||||
|
||||
### Standard
|
||||
|
||||
```hcl
|
||||
module "ecs_container_definition" {
|
||||
source = "terraform-aws-modules/ecs/aws//modules/container-definition"
|
||||
|
||||
name = "example"
|
||||
cpu = 512
|
||||
memory = 1024
|
||||
essential = true
|
||||
image = "public.ecr.aws/aws-containers/ecsdemo-frontend:776fd50"
|
||||
port_mappings = [
|
||||
{
|
||||
name = "ecs-sample"
|
||||
containerPort = 80
|
||||
protocol = "tcp"
|
||||
}
|
||||
]
|
||||
|
||||
# Example image used requires access to write to root filesystem
|
||||
readonly_root_filesystem = false
|
||||
|
||||
memory_reservation = 100
|

# Amazon ECS Service Module
|
||||
|
||||
Configuration in this directory creates an Amazon ECS Service and associated resources.
|
||||
|
||||
Some notable configurations to be aware of when using this module:
|
||||
1. `desired_count`/`scale` is always ignored; the module is designed to utilize autoscaling by default (though it can be disabled)
|
||||
2. The default configuration is intended for `FARGATE` use
|
||||
|
||||
For more details see the [design doc](https://github.com/terraform-aws-modules/terraform-aws-ecs/blob/master/docs/README.md)
|
||||
|
||||
### Logging
|
||||
|
||||
Please refer to [FireLens examples repository](https://github.com/aws-samples/amazon-ecs-firelens-examples) for logging configuration examples for FireLens on Amazon ECS and AWS Fargate.
