title: Run Single Task
nav_order: 36

Sometimes you do not want to run a long running `service` but a one time task. Running Rails migrations are an example of a one off task.  Here is an example of how you would run a one time task.

```
ufo task demo-web -c bundle exec rake db:migrate
```

At the end of the output you should see you the task ARN:

```sh
$ ufo task demo-web -c bundle exec rake db:migrate
...
Running task_definition: demo-web
Task ARN: arn:aws:ecs:us-west-2:994926937775:task/a0e4229d-3d39-4b26-9151-6ab6869b84d4
$
```

You can describe that task for more details:

```sh
aws ecs describe-tasks --tasks arn:aws:ecs:us-west-2:994926937775:task/a0e4229d-3d39-4b26-9151-6ab6869b84d4
```
