Docker for Pyramid

Three files are required to dockerize your Pyramid application. Copy & paste the contents to your project directory and run with docker-compose up After this command your webserver will be up and running server on the name firehose.dev port 8080.

Stack:

• Python >= 2.6
• Gunicorn
• nginx

docker-compose.yml

version: '3'
services:
  webserver:
    image: nginx:latest
    ports:
      - "8080:80"
    volumes:
      - "./site.conf:/etc/nginx/conf.d/site.conf"
    links:
      - backend
  backend:
    build: 
      context: .
      dockerfile: Pyramid.Dockerfile
    image: firehose/backend:latest
    volumes:
      - "./development.ini:/conf/settings.ini"
      # development only
      - "./:/app"
    # development only
    entrypoint:
      - gunicorn
      - --paster
      - /conf/settings.ini
      - -b
      - 0.0.0.0:8000
      - --reload

firehose.conf

server {
    listen 80;
    server_name firehose.dev;
    access_log  /var/log/nginx/firehose.log;

    location / {
        proxy_pass http://backend:8000;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

Pyramid.Dockerfile

FROM python:3.6-alpine

RUN pip install gunicorn

COPY . /app
WORKDIR /app
RUN python setup.py develop

VOLUME ['/conf'] 

RUN adduser -H -D monty
USER monty

CMD ["gunicorn", "--paster", "/conf/settings.ini", "-b", "0.0.0.0:8000"]

If you don't have an .egg file in your root directory gunicorn will throw an error:

    pkg_resources.DistributionNotFound: The 'firehose' distribution was not found and is required by the application

It is advised to run python setup.py develop with an auxiliary python 3.6 environment before running docker-compose up as workaround.
