|
|
|
|
A Story of Labels & Elastic Containers
|
|
{: .subtitle }
|
|
|
|
Attach labels to your ECS containers and let Traefik do the rest!
|
|
|
|
## Configuration Examples
|
|
|
|
??? example "Configuring ECS provider"
|
|
|
|
Enabling the ECS provider:
|
|
|
|
```toml tab="File (TOML)"
|
|
[providers.ecs]
|
|
clusters = ["default"]
|
|
```
|
|
|
|
```yaml tab="File (YAML)"
|
|
providers:
|
|
ecs:
|
|
clusters:
|
|
- default
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
--providers.ecs.clusters=default
|
|
```
|
|
|
|
## Policy
|
|
|
|
Traefik 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": [
|
|
"*"
|
|
]
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
## Provider configuration
|
|
|
|
### `autoDiscoverClusters`
|
|
|
|
_Optional, Default=false_
|
|
|
|
```toml tab="File (TOML)"
|
|
[providers.ecs]
|
|
autoDiscoverClusters = true
|
|
# ...
|
|
```
|
|
|
|
```yaml tab="File (YAML)"
|
|
providers:
|
|
ecs:
|
|
autoDiscoverClusters: true
|
|
# ...
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
--providers.ecs.autoDiscoverClusters=true
|
|
# ...
|
|
```
|
|
|
|
Search for services in clusters list.
|
|
|
|
- If set to `true` the configured clusters will be ignored and the clusters will be discovered.
|
|
- If set to `false` the services will be discovered only in configured clusters.
|
|
|
|
### `clusters`
|
|
|
|
_Optional, Default=["default"]_
|
|
|
|
```toml tab="File (TOML)"
|
|
[providers.ecs]
|
|
cluster = ["default"]
|
|
# ...
|
|
```
|
|
|
|
```yaml tab="File (YAML)"
|
|
providers:
|
|
ecs:
|
|
clusters:
|
|
- default
|
|
# ...
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
--providers.ecs.clusters=default
|
|
# ...
|
|
```
|
|
|
|
Search for services in clusters list.
|
|
|
|
### `exposedByDefault`
|
|
|
|
_Optional, Default=true_
|
|
|
|
```toml tab="File (TOML)"
|
|
[providers.ecs]
|
|
exposedByDefault = false
|
|
# ...
|
|
```
|
|
|
|
```yaml tab="File (YAML)"
|
|
providers:
|
|
ecs:
|
|
exposedByDefault: false
|
|
# ...
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
--providers.ecs.exposedByDefault=false
|
|
# ...
|
|
```
|
|
|
|
Expose ECS services by default in Traefik.
|
|
If set to false, services that don't have a `traefik.enable=true` label will be ignored from the resulting routing configuration.
|
|
|
|
### `defaultRule`
|
|
|
|
_Optional, Default=```Host(`{{ normalize .Name }}`)```_
|
|
|
|
```toml tab="File (TOML)"
|
|
[providers.ecs]
|
|
defaultRule = "Host(`{{ .Name }}.{{ index .Labels \"customLabel\"}}`)"
|
|
# ...
|
|
```
|
|
|
|
```yaml tab="File (YAML)"
|
|
providers:
|
|
ecs:
|
|
defaultRule: "Host(`{{ .Name }}.{{ index .Labels \"customLabel\"}}`)"
|
|
# ...
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
--providers.ecs.defaultRule=Host(`{{ .Name }}.{{ index .Labels \"customLabel\"}}`)
|
|
# ...
|
|
```
|
|
|
|
For a given container if no routing rule was defined by a label, it is defined by this defaultRule instead.
|
|
It must be a valid [Go template](https://golang.org/pkg/text/template/),
|
|
augmented with the [sprig template functions](http://masterminds.github.io/sprig/).
|
|
The service name can be accessed as the `Name` identifier,
|
|
and the template has access to all the labels defined on this container.
|
|
|
|
### `refreshSeconds`
|
|
|
|
_Optional, Default=15_
|
|
|
|
```toml tab="File (TOML)"
|
|
[providers.ecs]
|
|
refreshSeconds = 15
|
|
# ...
|
|
```
|
|
|
|
```yaml tab="File (YAML)"
|
|
providers:
|
|
ecs:
|
|
refreshSeconds: 15
|
|
# ...
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
--providers.ecs.refreshSeconds=15
|
|
# ...
|
|
```
|
|
|
|
Polling interval (in seconds).
|
|
|
|
### Credentials
|
|
|
|
_Optional_
|
|
|
|
```toml tab="File (TOML)"
|
|
[providers.ecs]
|
|
region = "us-east-1"
|
|
accessKeyID = "abc"
|
|
secretAccessKey = "123"
|
|
```
|
|
|
|
```yaml tab="File (YAML)"
|
|
providers:
|
|
ecs:
|
|
region: us-east-1
|
|
accessKeyID: "abc"
|
|
secretAccessKey: "123"
|
|
# ...
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
--providers.ecs.region="us-east-1"
|
|
--providers.ecs.accessKeyID="abc"
|
|
--providers.ecs.secretAccessKey="123"
|
|
# ...
|
|
```
|
|
|
|
If `accessKeyID` / `secretAccessKey` is not provided 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
