Error in invoke db-export due to incorrect service name and obsolete version warnings

[ndmitri]

Description

When running invoke db-export within the nautobot-docker-compose project, the command fails due to warnings about deprecated version fields in YAML configuration files and a service naming error indicating "no such service: postgres."

Steps to Reproduce

1. Clone the nautobot-docker-compose repository.
2. Navigate to the project directory.
3. Execute the command invoke db-export.

Expected Behavior

The database export process should execute without errors, properly identifying the correct database service name and avoiding any deprecated warnings.

Actual Behavior

The following issues were encountered:

• Obsolete version field warnings in docker-compose.postgres.yml, docker-compose.base.yml, and docker-compose.local.yml.
• Error message: "no such service: postgres".

It was noted that the actual database service is named db and not postgres, as evidenced by docker ps output.

Possible Fix

• Modify the tasks.py file to reference the correct service name (db instead of postgres).
• Review and update the Docker Compose YAML files to comply with current Docker standards, specifically removing or updating the deprecated version field.

Additional Information

• It may be necessary to confirm the database service configuration to ensure the service is intended to use PostgreSQL and not MySQL, as inferred by the use of the postgres:13-alpine image.
