and my docker file is :

FROM ubuntu:18.04

RUN apt-get update && apt-get install -y python3 python3-pip sudo

RUN apt-get install -y libsm6 libxext6 libxrender-dev

RUN apt-get -y install cmake protobuf-compiler

RUN useradd -m rishav

RUN chown -R rishav:rishav /home/rishav/

COPY --chown=rishav . /home/rishav/app

USER rishav

RUN cd /home/rishav/app/

WORKDIR /home/rishav/app

RUN  pip3 install -r requirements.txt

EXPOSE 8080

ENTRYPOINT python3 server.py

But then when I am trying to build docker, It gives me an error :

Collecting tensorflow==2.3.0 (from -r requirements.txt (line 39)) Could not find a version that satisfies the requirement tensorflow==2.3.0 (from -r requirements.txt (line 39)) (from versions: 0.12.1, 1.0.0, 1.0.1, 1.1.0rc0, 1.1.0rc1, 1.1.0rc2, 1.1.0, 1.2.0rc0, 1.2.0rc1, 1.2.0rc2, 1.2.0, 1.2.1, 1.3.0rc0, 1.3.0rc1, 1.3.0rc2, 1.3.0, 1.4.0rc0, 1.4.0rc1, 1.4.0, 1.4.1, 1.5.0rc0, 1.5.0rc1, 1.5.0, 1.5.1, 1.6.0rc0, 1.6.0rc1, 1.6.0, 1.7.0rc0, 1.7.0rc1, 1.7.0, 1.7.1, 1.8.0rc0, 1.8.0rc1, 1.8.0, 1.9.0rc0, 1.9.0rc1, 1.9.0rc2, 1.9.0, 1.10.0rc0, 1.10.0rc1, 1.10.0, 1.10.1, 1.11.0rc0, 1.11.0rc1, 1.11.0rc2, 1.11.0, 1.12.0rc0, 1.12.0rc1, 1.12.0rc2, 1.12.0, 1.12.2, 1.12.3, 1.13.0rc0, 1.13.0rc1, 1.13.0rc2, 1.13.1, 1.13.2, 1.14.0rc0, 1.14.0rc1, 1.14.0, 2.0.0a0, 2.0.0b0, 2.0.0b1) No matching distribution found for tensorflow==2.3.0 (from -r requirements.txt (line 39)) The command '/bin/sh -c pip3 install -r requirements.txt' returned a non-zero code: 1

I tried reducing the version of tensorflow to 2.0.0b1 but then it doesn't support keras. Please help.

I would suggest refactoring your Dockerfile a bit, with the following things in mind:

• Use one of the official python images to have more control over which version of python you use. The python:VERSION images, like python:3.8, include python as well as build tools like gcc. The python:VERSION-slim images do not include the build tools so they are smaller.
• Clean up the apt cache with rm -r /var/lib/apt/lists/* to reduce the final image size. That removes a cache that is not needed in the final image.
• Do not chown your home directory because it already belongs to rishav:rishav.
• Use the --no-cache-dir option in pip install to reduce the size of the final image. This prevents pip from caching the downloaded packages.
• Use the exec form for ENTRYPOINT, because the Dockerfile reference says it is preferred.

FROM python:3.8

RUN apt-get update \
    && apt-get install -y \
        cmake libsm6 libxext6 libxrender-dev protobuf-compiler \
    && rm -r /var/lib/apt/lists/*

RUN useradd -m rishav

COPY --chown=rishav:rishav . /home/rishav/app

USER rishav

WORKDIR /home/rishav/app

RUN pip install --no-cache-dir -r requirements.txt

EXPOSE 8080

ENTRYPOINT ["python3", "server.py"]
