Issue running playwright-python in docker container

my project is using playwright-python and my team has been unable to run playwright in a docker container. We are able to build the docker image successfully, but problems arise when the image is running. May I obtain some guidance on how to tackle this issue?

We are using Ubuntu 20.04 Focal, so it is not a version issue.

Here is the configuration of our Dockerfile.

# syntax=docker/dockerfile:1
FROM python:3.8

#ENV PATH=.envScriptsActivate.ps1

WORKDIR /code



#RUN which python3

COPY ./requirement.txt /code/requirement.txt
#RUN set -xe 
#    && apt-get update -y 
#    && apt-get install - y python3-pip
#RUN pip3 install -r requirement.txt
RUN set -xe
RUN apt-get upgrade -y
RUN apt-get update
#RUN add-apt-repository ppa:deadsnakes/ppa
RUN apt-get install -y python3 pip
#RUN python3 --version

RUN pip3 install --no-cache-dir --upgrade -r /code/requirement.txt

COPY ./ /code/server
RUN playwright install
RUN playwright install-deps
RUN ls -al
SHELL ["/bin/bash", "-c", "source /code/server/env/bin/activate && pip3 install --upgrade -r /code/requirement.txt"]

CMD ["python3", "-m", "uvicorn", "server.main:app", "--port", "9900", "--host", "0.0.0.0"]

Here is the error we are getting:

We have tried many ways to install playwright but we can’t get to install playwright in the image.

    This was an existing issue that was fixed in some earlier release. It shouldn’t be happening now. As suggested in this thread, can you try installing libxtst6 using this command RUN apt-get install -y python3 pip && apt install libxtst6 and then try with the docker image

    I was NOT able to install Playwright dependencies starting from a Python base image (ie FROM python:3.9), the only way to get it working was to use an Ubuntu base image which is supported OS by Playwright, then install Python and the rest (application dependencies and Playwright)

    FROM ubuntu:20.04

RUN apt update
RUN apt install -y python3.9
RUN apt install -y python3-pip

COPY app/ /app
WORKDIR /app

RUN pip install -r requirements.txt

RUN playwright install --with-deps chromium

CMD ....
