HowTo build a Docker Image

... for my python experiments

• Use the latest ubuntu docker-image from hub.docker.com

  • as I need the recent libolm3 and libolm-dev
• In my git repository I created

  • the .dockerignore file
• as well as the subfolder docker in which I created

  • the Dockerfile and
  • the docker-compose.yml.

Dockerfile

# syntax=docker/dockerfile:1

FROM ubuntu:latest

ENV TZ=Europe/Berlin
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

WORKDIR /app
VOLUME /app

COPY . .

RUN ls -la
RUN ["cat", "/app/requirements.txt"]

RUN /bin/bash -c 'apt update && apt install -y libolm-dev python3-pip ffmpeg;'


RUN pip install update pip && pip install -r requirements.txt


CMD python3 fritzab2matrix.py && tail -f /dev/null

docker-compose.yml

version: "3.7"

services:
  app:
    container_name: "fritzab2matrix"
    build:
      context: ../.
      dockerfile: ./docker/Dockerfile
    working_dir: /app
    volumes:
      - ./:/app

.dockerignore
