echo '<======================================'

```


2. Given docker-compose.yml

```

services:

  mongo:

    image: mongo:4.4

The server generated these startup warnings when booting:

        2021-01-25T16:52:03.600+00:00: Using the XFS filesystem is strongly recommended with the WiredTiger storage engine. See http://dochub.mongodb.org/core/prodnotes-filesystem

        Enable MongoDB's free cloud-based monitoring service, which will then receive and display

        metrics about your deployment (disk utilization, CPU, operation statistics, etc).


        The monitoring data will be available on a MongoDB website with a unique URL accessible to you

        and anyone you share the URL with. MongoDB may use this information to make product

        improvements and to suggest MongoDB products and deployment options to you.


        To enable free monitoring, run the following command: db.enableFreeMonitoring()

        To permanently disable this reminder, run the following command: db.disableFreeMonitoring()
