I recently started learning docker and I was attempting to build a flask python image by following a tutorial video.
FROM ubuntu:latest
RUN apt-get update
RUN apt-get install python
CMD echo "Python Installed"
RUN pip install flask
COPY . /opt/source-code
ENTRYPOINT FLASK_APP=/opt/source-code/app.py flask run
this is the Dockerfile in my source code working directory, I run sudo docker build . -t nxte/custom-app on a digitalocean droplet with docker installed but it returns The command '/bin/sh -c apt-get install python' returned a non-zero code: 1.
Any suggestions? I have no idea what the problem is since I followed the tutorial to a T.
You should use -y with apt-get:
RUN apt-get -y install python
Also notice that the above does not install pip and it's not
possible to install it with apt-get -y install python-pip so either
switch to Python 3 and then apt-get -y install python3 and apt-get -y install python3-pip or get pip from other sources.

I am trying to deploy my docker container on AWS Lambda. However, I use pdf2image package in my code which depends on poppler. To install poppler, I need to insert the following line in the Dockerfile.
RUN apt-get install -y poppler-utils
This is the full view of the dockerfile.
FROM ubuntu:18.04
RUN apt-get update
RUN apt-get install -y poppler-utils
RUN apt-get install python3 -y
RUN apt-get install python3-pip -y
RUN pip3 install --upgrade pip
WORKDIR /
COPY app.py .
COPY requirements.txt .
RUN pip3 install -r requirements.txt
ENTRYPOINT [ "python3", "app.py" ]
However, to deploy on Lambda, I need to use AWS base python image for Lambda. This is my attempt to rewrite the above dockerfile to use the Lambda base image.
FROM public.ecr.aws/lambda/python:3.6
# Cannot run the follow lines: apt-get: command not found
# RUN apt-get update
# RUN apt-get install -y poppler-utils
COPY app.py .
COPY requirements.txt .
RUN pip install -r requirements.txt
CMD ["app.handler"]
Based on the dockerfile above, you can see that the apt-get command cannot be run. Understandable because it is not from ubuntu image like I did earlier. My question is, how can I install the poppler in the Lambda base image?
It uses the yum package manager, so you can do the following instead:
FROM public.ecr.aws/lambda/python:3.6
RUN yum install -y poppler-utils
I was using the below docker file for quite sometime it was working well, But today when i tried to build the image it is throwing that pip is not installed, even though it is installed in the previous step
/bin/sh: 1: pip: not found
The command '/bin/sh -c pip install setuptools wheel' returned a non-zero code: 127
Below is the text of Dockerfile till the point where the error occurred:
FROM openjdk:8-jdk-slim
LABEL maintainer="abc#ab.com"
ARG RELEASE=2.13.2
ARG UID=1000
ARG GID=1000
RUN apt-get update
RUN apt-get install --no-install-recommends -y
RUN apt-get install tzdata -y
RUN apt-get install nano -y
RUN apt-get install curl -y
RUN apt-get install vim -y
RUN apt-get install python3 -y
RUN apt-get install python3-pip -y
RUN apt-get install unzip -y
RUN ln -s `which python3` /usr/bin/python
RUN pip3 install --upgrade pip
RUN pip install setuptools wheel
RUN pip install Flask flask-swagger-ui requests
RUN apt-get install --reinstall procps -y
I am not sure what happened suddenly , my attempt into looking for similar issues didn't yield a reason so for :
Docker issue: /bin/sh: pip: not found
Install pip in docker
Docker Build can't find pip
I'm trying to build a docker image with docker-compose in my ARM64 rasperry pi but it seems to be imposible.
This is my dockerfile:
FROM python:3.6-slim
RUN apt-get update && apt-get -y install python3-dev
RUN apt-get -y install python3-numpy
RUN apt-get -y install python3-pandas
ENTRYPOINT ["python3", "app.py"]
It seems to be OK, but when app.py is run, it gives an error: "Module numpy not found", and the same for pandas module.
If I try to install numpy and pandas using pip:
RUN pip install numpy pandas
It gives me an error or, more usually, the raspberry just gets frozen and I have to unplug it to recover.
I have tried with different versions of python for the source image and also using several ubuntu images and installing python.
Any idea of how can I install numpy and pandas in docker for my raspberry pi (ARM64)?
Thanks
The problems seems to be with the python version. I'm using a python3.6 docker image but, both python3-numpy and python3-pandas packages require python3.5, so when those packages are installed a new version of python is also installed. This is why when I'm trying to import those modules the python interpreter can't found them, because they are installed for another python version.
Finaly I solved it using a generic docker debian image and installing python3.5 myself instead of using a python docker image.
FROM debian:stretch-slim
RUN apt-get update && apt-get -y dist-upgrade
RUN apt-get -y install build-essential libssl-dev libffi-dev python3.5 libblas3 libc6 liblapack3 gcc python3-dev python3-pip cython3
RUN apt-get -y install python3-numpy python3-sklearn
RUN apt-get -y install python3-pandas
COPY requirements.txt /tmp/
RUN pip3 install -r /tmp/requirements.txt
(Disclaimer: The Raspberry Pi 3 B+ is probably too slow to install big dependecies like numpy)
This Dockerfile worked for me on the Raspberry Pi 3 B+ with Software-Version: Linux raspberrypi 5.10.63-v7+ (Consider updating it)
FROM python:3.9-buster
WORKDIR /
COPY requirements.txt requirements.txt
RUN pip3 install -r requirements.txt
I am not sure, but I think it helped also to clean docker i.e. remove all images and containers with the following commands:
Warning: This commands deletes all images and containers!
$ docker container prune
$ docker image prune -a
Or reset Docker completely (deletes also volumes and networks):
$ docker system prune --volumes
I recommend to create requirements.txt file.
Inside you can declare packets to install.
The `Dockerfile':
FROM python
COPY app.py /workdir/
COPY requirements.txt /workdir/
WORKDIR /workdir
RUN pip install --trusted-host pypi.python.org -r requirements.txt
CMD python app.py
edit
I create Dockerfile which import pandas lib and then checking if it work:
cat Dockerfile
FROM python
COPY app.py /workdir/
WORKDIR /workdir
RUN python -m pip install pandas
CMD python app.py
I'm trying to install apache-airflow the recommended way with pip install apache-airflow. During the install of pendulum (a dependency), I get an error:
error: can't copy 'pendulum/parsing': doesn't exist or not a regular file
I think it's related to Python distutils error: "[directory]... doesn't exist or not a regular file", but that doesn't give an answer as to how one resolves this when using pip. Pulling the tar for pendulum and installing using python setup.py install works, but then when subsequently I do pip install apache-airflow again, it sees that pendulum is already installed, UNINSTALLS, and then tries to install again using pip, resulting in the same error. I'm using a docker container and installing python-setuptools with apt-get before I do any of this. Here's my dockerfile, fwiw...
FROM phusion/baseimage:0.10.1
MAINTAINER a curious dev
RUN apt-get update && apt-get install -y python-setuptools python-pip python-dev libffi-dev libssl-dev zip wget
ENV SLUGIFY_USES_TEXT_UNIDECODE=yes
RUN wget https://files.pythonhosted.org/packages/5b/57/71fc910edcd937b72aa0ef51c8f5734fbd8c011fa1480fce881433847ec8/pendulum-2.0.4.tar.gz
RUN tar -xzvf pendulum-2.0.4.tar.gz
RUN cd pendulum-2.0.4/ && python setup.py install
RUN pip install apache-airflow
CMD airflow initdb && airflow webserver -p 8080
Does anyone see anything I'm doing wrong? I haven't found anyone else with this error so I think there's something really obvious I'm missing. Thanks for reading.
Upgrade pip first.
FROM phusion/baseimage:0.10.1
RUN apt-get update && apt-get install -y python-setuptools python-pip python-dev libffi-dev libssl-dev zip wget

RUN pip install apache-airflow
CMD airflow initdb && airflow webserver -p 8080
seems to work fine for me.
I used Dockerfile successfully built a container. However, my code doesn't work in the container. It does work if I install all the packages manually. I'm assuming I messed up something that cause docker didn't install the packages properly. So, I want to check whether python package is installed or not in Docker container. What is the best way to check it?
The Dockerfile I used:
# Update the sources list
RUN sudo apt-get update
# Install basic applications
RUN sudo apt-get install -y tar git curl nano wget dialog net-tools build-essential
# First install ZeroMQ
RUN sudo apt-get install -y libzmq-dev
# Install libevent
RUN sudo apt-get install -y libevent-dev
# Install Python and Basic Python Tools
RUN sudo apt-get install -y python python-dev python-setuptools
RUN sudo apt-get install -y python-pip
# Add the current directory to the container
ADD . /root/code
# Get pip to download and install requirements:
RUN sudo pip install -r /root/code/requirements.txt
# Expose ports
EXPOSE 80 4242
# Define working directory.
WORKDIR /root/code
# Start the tcp server.
CMD python app.py
The requirements.txt I used:
gevent==1.0.1
greenlet==0.4.5
msgpack-python==0.4.2
pyzmq==13.1.0
wsgiref==0.1.2
zerorpc==0.4.4
I figured out.
docker exec <container ID> pip list
