I have a python 3.6 app that I would like to install on a docker container. I installed the app in a virtual env (miniconda3) on my pc (windows 10) and need to do the same in a docker container (python3.6 base image (linux)). I installed the app locally using a setup.py file using python setup.py install, and an egg file as well as a separate directory with the application's code were created in site-packages. When I tried to do the same in the docker container, the installation creates only an egg file in site packages, and the app can't be imported. The other installed packages are fine.
Dockerfile:
FROM python:3.6
WORKDIR /opt

Any idea where I'm going wrong?

This Python 3.9 project has a Dockerfile, that builds successfully. The file makes use of an ENTRYPOINT script to create some directories and handle some clean-up at run time. It is a bash script. The ENTRYPOINT script has no problem running until the very end, where it is expected to execute the CMD that is passed next. Well, I should say this behavior only happens when Kaniko builds the image. When the image is built locally, no such problem occurs. However, I am willing to chalk that up to the fact that locally is on a Windows machine. However, that shouldn't matter here because the error thrown is:
/opt/project/conf/entrypoint.sh: /usr/bin/supervisord: /usr/bin/python3: bad interpreter: No such file or directory
/opt/project/conf/entrypoint.sh: line 8: /usr/bin/supervisord: Success
Now I have looked at many "bad interpreter" questions. They all seem to revolve around the interpreter being in a custom place. I am reliant upon the default spot for the Python 3.9 interpreter. On Debian Bullseye (The OS behind the base image) that should be /usr/local/bin/python or /usr/local/bin/python3. So I am completely stumped as to why it is unable to find or use it.
Here are the implementation details:

The image is ran and deployed without changes to the user, so it should be running as root.
In this case, after some digging I found there is an issue with the Kaniko version DevOps had running. That was causing the issue. Because the image wasn't being flattened correctly, Python could not start properly.
I try to run container from image nvcr.io/nvidia/tensorflow:22.08-tf2-py3. But I have a problem.
The built docker-image contains python3.8. But I don't understand why I have this version of python in my docker-image. It is necessary to use python with version>=3.10 for correct work with libraries that I need. Version=3.8 is not explicitly specified in Dockerfile. When I try to install an another version:
RUN apt-get update && apt-get install -y software-properties-common && add-apt-repository ppa:deadsnakes/ppa && apt-get install -y python3.11
RUN python3.11 -m pip install --upgrade --no-cache -r requirements.txt
I get an error /usr/bin/python3.11: No module named pip during image building.
How can I correctly install specific version of python in my docker-image using Dockerfile?
You got Python 3.11 alright but you are missing the PIP module. Add python-pip or python3-pip to the list of packages you install with apt-get.
This is regarding your problem with python3.11 pip and not the tensor version support
Looking at the original python3.11 docker in here you should be able to use the bellow code.
# if this is called "PIP_VERSION", pip explodes with "ValueError: invalid truth value '<VERSION>'"
ENV PYTHON_PIP_VERSION 22.3
# https://github.com/docker-library/python/issues/365

I was able to install pip for my python3.11 on Fedora(outside Docker) using python3 -m ensurepip (taken from here)
I am trying to install python 3.5 inside docker with a base image centos7. This is our Dockerfile
FROM base-centos7:0.0.8
# Install basic tools
RUN yum install -y which vim wget git gcc
# Install python 3.5
RUN yum install -y https://repo.ius.io/ius-release-el7.rpm \
&& yum update -y \
&& yum install -y python35u python35u-libs python35u-devel python35u-pip
RUN python3.5 -m pip install --upgrade pip
But during the build, docker build image is failing with the following errors
executor failed running [/bin/sh -c yum install -y https://repo.ius.io/ius-release-el7.rpm
&& yum update -y
&& sudo yum install -y python35u python35u-libs python35u-devel python35u-pip]: exit code: 127.
Can anyone guide me in resolving this issue. and why am I seeing this issue in very first place.
You can use python image from docker hub
https://hub.docker.com/_/python
Example of dockerfile :
FROM python:3.6
RUN mkdir /code
WORKDIR /code
ADD . /code/
RUN pip install -r requirements.txt
EXPOSE 5000
CMD ["python", "/code/app.py"]
i think it's easy , isn't ?
the centos repo uses:
FROM centos/s2i-base-centos7
EXPOSE 8080
ENV PYTHON_VERSION=3.5 \

The problem is not difficult, I build the image changing
FROM base-centos7:0.0.8 ====> FROM centos:7
You can consult the images version of centos in https://hub.docker.com/_/centos
PD: The container showed: errro exited(1), you should focus on the main process.
I've got a CentOS 8 install, and I'm trying to use a docker container to run Mattermost to set up a local node for my family to use. I've been searching a lot online, but my google-fu appears to be weak as I can't get answers that address my issue.
I've downloaded docker, and docker compose using the following guide, again tailoring it to Centos - https://docs.mattermost.com/install/prod-docker.htm I've successfully run the "Hello World" container.
I'm using this guide and trying to tailor the Mattermost container install - https://wiki.archlinux.org/index.php/Ma ... ith_Docker
I've edited the ~/mattermost-docker/db/Dockerfile to remove references to apk, and put in yum and then dnf, and tried to execute with SUDO in the script and using SU account to run the script. Latest Dockerfile:
FROM postgres:9.4-alpine
ENV DEFAULT_TIMEZONE UTC

ENTRYPOINT ["/entrypoint.sh"]
CMD ["postgres"]
VOLUME ["/var/run/postgresql", "/usr/share/postgresql/", "/var/lib/postgresql/data", "/tmp", "/etc/wal-e.d/env"]
However it still fails on: docker-compose build

Confirmed dnf, and yum are present in /bin and /usr/bin, confirmed /bin/sh -> /bin/bash. I'm not even sure what question I should be asking, so I'd appreciate some assistance in figuring out how I can get this container stood up.
Thanks.
I want to create a docker image with specifically python 3.5 on a specific base image which is the nvidia/cuda (9.0-base image) the latter has no python environment.
The reason I need specific versions is to support running cuda10.0 python3.5 and a gcc version<7 to compile the driver all together on the same box
When I try and build the docker environments (see below) I always end up with the system update files which load python3.6
The first version I run (below) runs a system update dependencies which installs python 3.6 I have tried many variants to avoid this but always end up 3.6 in the final image.
Any suggestions for getting this running with python3.5 are welcome
Thanks
FROM nvidia/cuda
RUN apt-get update && apt-get install -y libsm6 libxext6 libxrender-dev python3.5 python3-pip
COPY . /app
WORKDIR /app
RUN pip3 install -r requirements.txt

CMD [ "app.py" ]
Another variant (below) I have tried is with virtualenv and here again I can't seem to force a python 3.5 environment

You can try using conda. I used several stages to minimize final container and to speedup/cache local builds.
