Connection refused for local server in github actions workflow - continuous-integration

Question

I'm trying to run a local server for my project CI/CD Pipeline. When I start the server I got a "Connection refused" on it.
My project is a fastAPI application and I'm trying to run a integration tests on PR to validate the app before merge the code. I tried to start my app directly (gunicorn), building a docker image and starting it... I tried a lot of things. Then, I tried to run a simple server instead of my app and... got the same error!
This is my simple server workflow:
on:
push:
branches:
- "develop"
jobs:
mylocalserver:
name: Run server
runs-on: ubuntu-latest
steps:
- name: Setup python
uses: actions/setup-python#v3
with:
python-version: 3.9
- name: Run server in background
run: |
python -V
python -m http.server 3000 &> /dev/null &
sudo lsof -i -P -n | grep LISTEN
curl http://localhost:3000
- name: Run server with console
run: |
python -m http.server 3000
Output:
If I run my app with console (no daemon mode in gunicorn), the server start and log to console in workflow with success:
But this way I cannot run nothing after this (and I have to cancel workflow). Some idea? Thank you!

Maybe not the best answer, but for now runnig the job into a container works (only add a container label in question example). Example for my fastAPI app:
on:
pull_request:
branches:
- 'main'
- 'develop'
jobs:
run-on-pr:
runs-on: ubuntu-latest
container: ubuntu
services:
mongodb:
image: mongo
ports:
- 27017:27017
steps:
- name: Setup git
run: |
apt-get update; apt-get install -y git
- name: Git checkout
uses: actions/checkout#v3
with:
path: api
- name: Setup python
uses: actions/setup-python#v4
with:
python-version: 3.9
- name: Install pip
run: |
apt-get update; apt-get install -y python3-pip
- name: Build and ENV
run: |
cd api
cp .env_example_docker .env
pip3 install -r requirements.txt
- name: Run fastAPI
run: |
cd api
gunicorn -D -k uvicorn.workers.UvicornWorker -c ./gunicorn_conf.py app.main:app
env:
MONGO_URL: "mongodb://mongodb:27017"
- name: Install curl
run: |
apt-get update; apt-get install -y curl
- name: Run curl
run: |
curl http://localhost:3000
This works, but I have to install all in container (git, pip). I will try a solution without using the container label and if I found anything I can post here.
