When use logging driver `awslogs`, if I don’t define `awslogs-stream`, the log for each container will be automatically exported to log group `docker` with log stream `Docker ID` (A hash key for that container)

```
logging:
  driver: awslogs
  options:
    awslogs-group: docker
    awslogs-region: us-east-2

```

[The document](https://docs.docker.com/config/containers/logging/awslogs/#awslogs-stream) gives the same statement

> awslogs-stream

> To configure which log stream should be used, you can specify the awslogs-stream log option. If not specified, the container ID is used as the log stream.

> Note: Log streams within a given log group should only be used by one container at a time. Using the same log stream for multiple containers concurrently can cause reduced logging performance.

What I try to do is, I’d like to add postfix after this Docker ID, such as `${docker_id}-${team}-${project}-${environment}`

what can I do?

### Update 1

Maybe I got the answer by myself,

[Amazon CloudWatch Logs logging driver - tag](https://docs.docker.com/config/containers/logging/awslogs/#tag)

### Update 2

Not sure if Rancher support log tag or not.

[Issue: awslogs driver doesn’t support tag option](https://github.com/rancher/rancher/issues/8235)
