docker_python

Setup

• Install docker-compose
• Clone repo by one of the following ways
  • git clone https://github.com/pythoninthegrass/docker_python.git
  • Open in GitHub Desktop

Usage

• Start web server

  cd docker_python/
  docker-compose up --build --remove-orphans

• Open boilerplate Django server at http://127.0.0.1:8000/
• Ctrl-C to stop server
  • Note
    • Running docker-compose up will clean up after itself when run without the -d switch
    • Analogous to docker run -it --rm docker_python bash

Troubleshooting

• Verify server is listening on port 8000

  $ netstat -na | grep 8000
  tcp46      0      0  *.8000                 *.*                    LISTEN

• Watch logs in real-time: docker logs -tf --tail="50" python-docker
• Check exit code

  $ docker-compose ps
  Name                          Command               State    Ports
  ------------------------------------------------------------------------------
  docker_python_dockerpython_1   python manage.py runserver ...   Exit 0

Build

• Remove docker volume

  $ docker ps -a
  CONTAINER ID   IMAGE                         COMMAND                  CREATED         STATUS                       PORTS     NAMES
  66696bb035bc   docker_python                 "python manage.py ru…"   8 minutes ago   Exited (0) 36 seconds ago              docker_python_dockerpython_1
  $ docker rm -v 66696bb035bc

• Remove docker image

  docker images
  docker rmi docker_python:latest

• Rebuild outside of docker-compose

  # build
  docker build --tag docker_python .
  
  # tag as version other than latest
  docker tag <457e6d6c2d25> docker_python:v1.5

TODO

• Add GitHub URL
• Convert pip to pipenv
