How to run Colima with docker-compose in Pycharm (or other Jetbrains project)

Question

When switching from Docker Desktop to colima I encountered problems with setting up Run configuration in Pycharm thru Docker-compose feature. Example setup

I keep getting this error from Pycharm:

no such service: 
container:9200f38c022e09065fbb972683cd8843c6faedf4b722ee573ea34303f604b843:ro 
Process finished with exit code 1

Versions:

Colima v 0.3.2 docker-compose v 2.2.3 PyCharm 2021.3.2 (Professional Edition)

I don't have a solution yet but I believe the culprit is that pycharm uses syntax for specifying containers unsupported by your (our) setup.
Pycharm integrates with docker-compose like this:

docker container with helper scripts in volume is created

$ docker ps  -a
...
346cc60545f6 aac5779e964d  "/bin/sh" Created pycharm_helpers_PY-213.6777.50

it creates it's own overlay. My project docker-compose.yml is version: 2, pycharm's override is:

$ cat /Users/.../Library/Caches/JetBrains/PyCharm2021.3/tmp/docker-compose.override.2.yml
version: "2"
services:
  app:
    command:
    - "python"
    - "-V"
    entrypoint: ""
    environment:
      PYTHONUNBUFFERED: "1"
    restart: "no"
    volumes: []
    volumes_from:
    - "container:346cc60545f6e7955661fc6f8f578c6f3f871a7330b068cb35224efbee05aae7:ro"

is calls docker-compose with the overlay:

docker-compose \
  -f /Users/.../projects/pythonProject1/docker-compose.yml \
  -f /Users/.../Library/Caches/JetBrains/PyCharm2021.3/tmp/docker-compose.override.9.yml \
  run --rm --no-deps app

Now if I try container: syntax with docker run I get an error:

$ docker run --rm -it \
  --volumes-from container:346cc60545f6e7955661fc6f8f578c6f3f871a7330b068cb35224efbee05aae7:ro \
  python:3.9 bash
docker: Error response from daemon: invalid mode: 346cc60545f6e7955661fc6f8f578c6f3f871a7330b068cb35224efbee05aae7:ro.
See 'docker run --help'.

With container: prefix removed it works:

$ docker run --rm -it \
  --volumes-from 346cc60545f6e7955661fc6f8f578c6f3f871a7330b068cb35224efbee05aae7:ro \

coveragepy       pip-20.3.4-py2.py3-none-any.whl  pycharm_display   setuptools-44.1.1-py2.py3-none-any.whl  virtualenv.pyz

But with docker-compose.yml version: 3 I get different error

error during connect: Get "http://unix:2375/Users/.../.colima/docker.sock/v1.24/containers/json?all=1&filters=%7B%22label%22%3A%7B%22com.docker.compose.project%3Dpythonproject1%22%3Atrue%7D%7D&limit=0": dial tcp: lookup unix on 1.1.1.1:53: no such host

Process finished with exit code 1

Pycharm's docker-compose for 3.8 doesn't use container: syntax anymore:

$ cat /Users/.../Library/Caches/JetBrains/PyCharm2021.3/tmp/docker-compose.override.9.yml
version: "3.8"
services:
  app:
    command:
    - "python"
    - "-V"
    entrypoint: ""
    environment:
      PYTHONUNBUFFERED: "1"
    restart: "no"
    volumes:
    - "pycharm_helpers_PY-213.6777.50:/opt/.pycharm_helpers"
volumes:
  pycharm_helpers_PY-213.6777.50: {}

Wrapper script replacing the overlay with the one with contaner: prefix stripped would likely help us for version: 2, but the problem with version: 3.8 would persist.
