To set environment variables in a Docker container using a docker-compose.yml file, you can use the environment key within the service definition. Here is an example of how you can do this:

version: '3.8'
services:
  my_service:
    image: my_image:my_tag
    environment:
      - MY_ENV_VAR1=value1
      - MY_ENV_VAR2=value2

In this example, my_service is the name of the service, my_image:my_tag is the Docker image and tag, and MY_ENV_VAR1 and MY_ENV_VAR2 are the environment variables being set with their respective values.

If you are using TorizonCore and want to use the predefined environment variables provided by Torizon, you can reference them directly in your docker-compose.yml file. For example:

version: '3.8'
services:
  weston:
    image: torizon/weston:$CT_TAG_WESTON
    environment:
      - MY_ENV_VAR1=value1
      - MY_ENV_VAR2=value2

In this example, $CT_TAG_WESTON is an environment variable provided by TorizonCore that resolves to the appropriate tag for the Weston container.

Make sure to prepend the variable name with a dollar sign when running a command on Linux, as shown in the example.
