# ECS Provider
|
|
|
|
Træfik can be configured to use Amazon ECS as a provider.
|
|
|
|
## Configuration
|
|
|
|
```toml

|

# 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)
|

#
|

```
|
|
|
|
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": [
|
|
"*"
|
|
]
|
|
}
|
|
]
|
|
}
|
|
```
|
