Trying to install a container app that needs access via 2 ports

I have a container app running locally that has two ports exposed: 8080 and 8050.  The former serves the UI and the latter is for uploads.  I am trying to figure out how to phrase this in both the docker compose file and in the az containerapp up command.    I am trying to decipher this document.  Can I have a primary (serving the UI) and a secondary port? I am confused by the distinction between "target port" and "external port".     Here is a snippet from my docker-compose:

python-server:
    privileged: true
    build:
      context: .
      dockerfile: dockerfile
    working_dir: /
    ports:
      - '8080:8080'
      - '8050:8050'​

 Here is my powershell command:

$RG="<redacted>" 
$ACA_ENVIRONMENT="<redacted>" 
$ACA_NAME="<redacted>" 
$REGION_NAME="eastus" 
$ACR_NAME="<redacted>" 
$IMAGE_NAME="<redacted>" 
$TARGET_PORT="8080" 
$INGRESS="external" 
$QUERY="properties.configuration.ingress.fqdn" 

az containerapp up --name $ACA_NAME --resource-group $RG --environment $ACA_ENVIRONMENT --image $IMAGE_NAME --target-port $TARGET_PORT --ingress $INGRESS --query $QUERY
