I know there are more similar questions but none of them solve the problem that I am having. I have assembled a very basic Python application with Flask:

from flask import Flask

app = Flask(__name__)

@app.route('/')
def index():
    return 'HELLO WORLD!'

app.run(host='0.0.0.0', port=8000)

Where older I have created a false unit test:

def calc(x, y):
    return x + y

def test_calc():
    assert 5 == calc(2, 3)

What I really want to create is a CI that creates a docker image, do the tests, and then post the docker image to Docker Hub but running this command to run the tests docker-compose run app sh -c "pytest test.py --cov -p no:cacheprovider" I get the error:

test.py .                                                                                                                                                   [100%]

  • The code you show doesn't mention a database at all. Is there more of the application or test setup you haven't included? – David Maze Sep 30 '20 at 13:25
  • @DavidMaze No, it's just that. The rest is the docker-compose and the Dockerfile but i don't mention any database – Kevimuxx69 Sep 30 '20 at 13:39
  • Could you add your Dockerfile to the question please? – oschlueter Sep 30 '20 at 15:41

    hi @Kevimuxx69 were you able to solve this issue? I am facing a similar issue in CircleCI with `sqlite3.OperationalError: unable to open database file` . I am using python:3.8-alpine image to build the application – anandg112 Dec 24 '20 at 23:08

    I had this issue with Docker on Github Actions and "solved" it by running the docker test command as root; `docker-compose run -u root --rm web \ bin/wait-for-postgres.sh coverage run --source=idp_data manage.py test` – Paul Watson Feb 05 '21 at 09:25
  • This still fails the Ci with exit code 5 – onlinejudge95 Jul 05 '21 at 10:41

I had the same issue. User from container can't create files in working dir. So, executing as root could solve issue. You could also change working dir or add permissions to user.
