Docker Build not working anymore

[MinehubDE]

After upgrading to the latest code and building the Docker image from it, snappass stops working and runs into an endless restart loop, due to the following error:

Traceback (most recent call last):
  File "/usr/local/bin/snappass", line 33, in <module>
    sys.exit(load_entry_point('snappass==1.6.0', 'console_scripts', 'snappass')())

    return next(matches).load()

ImportError: cannot import name 'url_quote_plus' from 'werkzeug.urls' (/usr/local/lib/python3.8/site-packages/werkzeug-3.0.1-py3.8.egg/werkzeug/urls.py)

I assume it's caused by any version update from the requirements.txt, but couldn't figure out which constellation would result in a working app again.

I faced the same issue. It looks like that there is a conflict between flask and snappass, both requiring a specific version of Werkzeug.

Workaround

requirements.txt

cryptography==41.0.4
Flask==2.3.2
itsdangerous==2.1.2
Jinja2==3.1.2
MarkupSafe==2.1.1
redis==5.0.1
Werkzeug==2.3.3

Dockerfile

FROM python:3-alpine

RUN apk update && apk upgrade
WORKDIR /app
COPY requirements.txt .
RUN pip install -r requirements.txt
RUN pip install snappass

ENTRYPOINT ["snappass"]

docker-compose.yaml

version: '2'

services:

    snappass:
        image: testsnappass
        ports:
            - "5000:5000"
        stop_signal: SIGINT
        environment:
            - REDIS_HOST=redis
            - NO_SSL=True
        depends_on:
          - redis

    redis:
        image: "redis:latest"

Run: docker image build -t testsnappass .; docker-compose up -d

Enjoy.

Its missing PIP packages which aren't installed, i fixed it by removing requirements.txt from .dockerignore and adding

COPY requirements.txt .

RUN pip install -r requirements.txt

In the Dockerfile then it built and ran fine

Hi everyone, sorry for the late response. The issue should have been resolved by #303
