I built a ubuntu image using the following Dockerfile:
FROM ubuntu:20.04
# Disable Prompt During Packages Installation
ARG DEBIAN_FRONTEND=noninteractive
# Add 32bit architecture
RUN dpkg --add-architecture i386 \
&& apt-get update \
&& apt-get install -y libc6:i386 libncurses5:i386 libstdc++6:i386 zlib1g:i386
RUN apt-get update && apt-get install -y locales && rm -rf /var/lib/apt/lists/* \
&& localedef -i en_US -c -f UTF-8 -A /usr/share/locale/locale.alias en_US.UTF-8
ENV LANG en_US.utf8
RUN apt-get update && apt-get install -y \
iputils-ping \
python3 python3-pip
# Copy app to container
COPY . /app
WORKDIR /app
# Install pip requirements
COPY requirements.txt /app
RUN python3 -m pip install -r requirements.txt
# During debugging, this entry point will be overridden. For more information, please refer to https://aka.ms/vscode-docker-python-debug
CMD ["bash"]
I've been trying to run a 32bit app (hence the first run command in the Dockerfile) I have inside the my_app directory using:
./app
but I keep getting
bash: ./app: No such file or directory
I build your docker file with no error, do you have more detail ?

I have a docker file in which I do wget to copy something in the image. But the build is failing giving 'wget command not found'. WHen i googled I found suggestions to install wget like below
RUN apt update && apt upgrade
RUN apt install wget
Docker File:
FROM openjdk:17
LABEL maintainer="app"

ARG pwd
RUN useradd -ms /bin/bash -u 1000 user1

ENTRYPOINT ["sh", "/docker_entrypoint.sh"]
On doing this I am getting error app-get not found. Can some one suggest any solution.
The openjdk image you use is based on Oracle Linux which uses microdnf rather than apt as it's package manager.
To install wget (and unzip which you also need), you can add this to your Dockerfile:
RUN microdnf update \
&& microdnf install --nodocs wget unzip \
&& microdnf clean all \
&& rm -rf /var/cache/yum
The commands clean up the package cache after installing, to keep the image size as small as possible.
I have the following Dockerfile, currently working locally in my device:
FROM python:3.7-slim-buster
WORKDIR /app
COPY . /app
VOLUME /app
RUN chmod +x /app/cat/sitemap_download.py
COPY entrypoint.sh /app/entrypoint.sh
RUN chmod +x /app/entrypoint.sh
ARG VERSION=3.7.4
RUN apt update && \
apt install -y bash wget && \
wget -O /tmp/nordrepo.deb https://repo.nordvpn.com/deb/nordvpn/debian/pool/main/nordvpn-release_1.0.0_all.deb && \
apt install -y /tmp/nordrepo.deb && \
apt update && \
apt install -y nordvpn=$VERSION && \
apt remove -y wget nordvpn-release
RUN apt-get clean \
&& apt-get -y update
RUN apt-get -y install python3-dev \
python3-psycopg2 \
&& apt-get -y install build-essential
RUN pip install --upgrade pip
RUN pip install -r cat/requirements.txt
RUN pip install awscli
ENTRYPOINT ["sh", "-c", "./entrypoint.sh"]
But when I deploy it to Fargate, the container stops before reaching the steady state with:
sh: 1: ./entrypoint.sh: not found
Edit: Adding entrypoint.sh file for clarification:
#!/bin/env sh
# start process, but it should exit once the file is in S3
/app/cat/sitemap_download.py
# Once the process is done, we are good to scale down the service
aws ecs update-service --cluster cluster_name --region eu-west-1 --service service-name --desired-count 0
I have tried modifying ENTRYPOINT to use it as exec form, or with full path but always get the same issue. Any ideas on what am I doing wrong?
I've managed to fix it now.
Changing the Dockerfile to look as follows solves the issue:
COPY . /app
VOLUME /app
RUN chmod +x /app/cat/sitemap_download.py
COPY entrypoint.sh /app/entrypoint.sh
RUN chmod +x /app/entrypoint.sh
ARG VERSION=3.7.4
RUN apt update && \
apt install -y bash wget && \
wget -O /tmp/nordrepo.deb https://repo.nordvpn.com/deb/nordvpn/debian/pool/main/nordvpn-release_1.0.0_all.deb && \
apt install -y /tmp/nordrepo.deb && \
apt update && \
apt install -y nordvpn=$VERSION && \
apt remove -y wget nordvpn-release
RUN apt-get clean \
&& apt-get -y update
RUN apt-get -y install python3-dev \
python3-psycopg2 \
&& apt-get -y install build-essential
RUN pip install --upgrade pip
RUN pip install -r cat/requirements.txt
RUN pip install awscli
ENTRYPOINT ["/bin/bash"]
CMD ["./entrypoint.sh"]
I tried this after reading: What is the difference between CMD and ENTRYPOINT in a Dockerfile?
I believe this syntax fixes it because with entrypoint I'm indicating bash to be run at start, and then passing the script as parameter.
I want to install rclone on a docker image in heroku to able to use Rclone with python telegram bot
I made a heroku.yml file
build:
docker:
worker: Dockerfile
run:
worker: bash start.sh
And start.sh as
python3 -m bot
And Dockerfile as
FROM ubuntu:18.04
WORKDIR /usr/src/app
RUN docker pull rclone/rclone:latest
RUN docker run rclone/rclone:latest version
RUN chmod 777 /usr/src/app
RUN apt -qq update

COPY . .
RUN locale-gen en_US.UTF-8
ENV LANG en_US.UTF-8
ENV LANGUAGE en_US:en
ENV LC_ALL en_US.UTF-8
CMD ["bash","start.sh"]
I get error The command '/bin/sh -c docker pull rclone/rclone:latest' returned a non-zero code: 127 in the git bash CLI
What Am I doing wrong? Or what is the procedure?
Thanks in advance!

Based on this answer
You can try this, also don't try to use docker commands inside a Dockerfile.
I have this file Dockerfile.nlu
FROM chatbot/spacy:latest
WORKDIR /app
COPY nlu ./agent_nlu
RUN python –m rasa_nlu.train --config agent_nlu/config.yml --data agent_nlu/data/ --path agent_nlu/agent --fixed_model_name default
and I get the error below:
]$ sudo docker build -t nlu:latest -f docker/Dockerfile.nlu .
Sending build context to Docker daemon 9.216kB
Step 1/4 : FROM chatbot/spacy:latest

Step 3/4 : COPY nlu ./agent_nlu
COPY failed: stat /var/lib/docker/tmp/docker-builder363868051/nlu: no such file or directory
It doesn't look like Docker can find the nlu directory. Are you sure it exists? Are you sure that you are executing the command from the correct directory?
But you also aren't installing Rasa at all or any of it's requirements. Is there a reason you aren't using the pre-built Rasa images? available here with docs here.
Here is a fully functional Docker file pulled from their repo.

I currently have the following Dockerfile to create my Docker image.
FROM python:3.6.6-alpine3.8
# Add dependencies for Python packages pandas, numpy and pyodbc
RUN apk add --no-cache curl gcc g++ unixodbc-dev
RUN ln -s /usr/include/locale.h /usr/include/xlocale.h

RUN pip install -r requirements.txt
I would like to include various ODBC drivers in this image so that I can use them to connect to different databases from the Python program running in my container.
The Python program is using Pyodbc to connect to databases.
The ODBC drivers I need to install are:
PostgreSQL
MySQL
Ms SQL Server
Teradata
Oracle
Hive
Impala
I wanted to start with PostgreSQL thinking it would be the easiest one but I could not find any package on the Alpine Linux Package manager. Do you have any idea how I should install such a driver?
I was facing the same issue. I solved this issue by adding RUN apk update before RUN apk add commands.(I was using python:3.6-alpine)
Dockerfile
FROM python:3.6-alpine
RUN apk update
RUN apk add gcc libc-dev g++ libffi-dev libxml2 unixodbc-dev mariadb-dev postgresql-dev
As the OP ended moving away from Alpine- to a Debian-base image, and another answer has a small snapshot of a working Dockerfile, I will flesh out a full Dockerfile that builds SQL Server ODBC Driver 17 into a Debian-base image.
# load python 3.8 dependencies using slim debian 10 image.
FROM python:3.8-slim-buster
# build variables.
ENV DEBIAN_FRONTEND noninteractive

if keeping it lightweight is your concerns, specifically in case of odbc, i recommend using debian:stretch image.
