Docker Compose Error: 'image' Must Be a Mapping, Not a String

The error message "'image' must be a mapping, not a string" indicates that your docker-compose.yml file has an issue with the format of the 'image' section for one of your services. It should be defined as a mapping, not a string.

To fix this, review your docker-compose.yml file and ensure the 'image' section for each service is correctly formatted as a mapping.

Here's an example of the correct format:

services:
  myservice:
    image:
      name: myimage
      tag: latest

Replace 'myservice', 'myimage', and 'latest' with the appropriate values for your application. Save the file and try running your Docker Compose command again.
