devspace init -> Docker-Compose migration ignores ENVs/--vars

[excalq]

What happened?

When running devspace init in an existing codebase having docker-compose.yaml, Devspace prompts for migration from Docker Compose. However, it seems to ignore either locally sourced/exported ENVs as well as use of --vars. When docker-compose.yaml uses ENVs for the ports values, the migration crashes.

set -a; source .env
# Same result with or without using --var=... below
devspace init --var=DB_PORT=27017 --var=EXPRESS_PORT=1337

? Docker Compose configuration detected. Do you want to create a DevSpace configuration based on Docker Compose? Convert existing docker-compose.yml to devspace.yaml

fatal 1 error(s) decoding:

* error decoding 'Ports': No port specified: :<empty>

What did you expect to happen instead?

Devspace would create a configuration respecting ENV setting of service's ports, and populate ENVs from the .env file.

How can we reproduce the bug? (as minimally and precisely as possible)

No devspace.yaml exist yet, new project in a small existing node.js codebase, with MongoDB and Redis DBs.

Local Environment:

• DevSpace Version: [use devspace --version]
  devspace version 6.3.12
• Operating System: windows | linux | mac
  MacOS
• ARCH of the OS: AMD64 | ARM64 | i386
  ARM64
  Kubernetes Cluster:
• Cloud Provider: google | aws | azure | other
  N/A
• Kubernetes Version: [use kubectl version]
  (Minikube, k8s 1.28)

Anything else we need to know?

Can you try setting the environment variables like this and report back?

DB_PORT=27017 EXPRESS_PORT=1337 devspace init

IIRC --var values won't be picked up by the docker-compose libraries used internally.
