# ECS Provider
Træfik can be configured to use Amazon ECS as a provider.
## Configuration
```toml
################################################################
# ECS Provider
################################################################
# Enable ECS Provider.
[ecs]
# ECS Clusters Name.
#
# Optional
# Default: ["default"]
#
clusters = ["default"]
# Enable watch ECS changes.
#
# Optional
# Default: true
#
watch = true
# Default domain used.
# Can be overridden by setting the "traefik.domain" label.
#
# Optional
# Default: ""
#
domain = "ecs.localhost"
# Enable auto discover ECS clusters.
#
# Optional
# Default: false
#
autoDiscoverClusters = false
# Polling interval (in seconds).
#
# Optional
# Default: 15
#
refreshSeconds = 15
# Expose ECS services by default in Traefik.
#
# Optional
# Default: true
#
exposedByDefault = false
# Region to use when connecting to AWS.
#
# Optional
#
region = "us-east-1"
# Access Key ID to use when connecting to AWS.
#
# Optional
#
accessKeyID = "abc"
# Secret Access Key to use when connecting to AWS.
#
# Optional
#
secretAccessKey = "123"
# Override default configuration template.
# For advanced users :)
#
# Optional
#
# filename = "ecs.tmpl"
# Override template version
# For advanced users :)
#
# Optional
# - "1": previous template version (must be used only with older custom templates, see "filename")
# - "2": current template version (must be used to force template version when "filename" is used)
#
# templateVersion = 2
```
If `accessKeyID`/`secretAccessKey` is not given credentials will be resolved in the following order:
- From environment variables; `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, and `AWS_SESSION_TOKEN`.
- Shared credentials, determined by `AWS_PROFILE` and `AWS_SHARED_CREDENTIALS_FILE`, defaults to `default` and `~/.aws/credentials`.
- EC2 instance role or ECS task role
To enable constraints see [provider-specific constraints section](/configuration/commons/#provider-specific).
## Policy
Træfik needs the following policy to read ECS information:
```json
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "TraefikECSReadAccess",
"Effect": "Allow",
"Action": [
"ecs:ListClusters",
"ecs:DescribeClusters",
"ecs:ListTasks",
"ecs:DescribeTasks",
"ecs:DescribeContainerInstances",
"ecs:DescribeTaskDefinition",
"ec2:DescribeInstances"
],
"Resource": [
"*"
]
}
]
}
```
