docker-mapnik

Mapnik Docker container with Python bindings

Building

❗ Ensure your Docker build environment, be it a VM (if you use Docker for Mac or Windows) or bare metal, has at least 4 gigabytes of memory. Any less and you'll have to enjoy hella swapping.

• Do docker build -t mapnik .. It will take a long while, so best get another coffee.

Image on dockerhub

• Image is available on dockerhub: docker pull anuras/mapnik

Contents of the image

• Ubuntu 16.04 LTS
• Mapnik 3.0.10 (at the time of writing)
• Python 2.7 & Python 3

Python bindings

• /opt/python-mapnik contains the Python bindings.
• The bindings are built for both Python 2.x and 3.x, and installed system-wide.
• If your app requires a virtualenv, pip install -e /opt/python-mapnik is likely your best bet.
• Otherwise, just --system-site-packages your virtualenv or don't use a virtualenv at all.

Test apps

• The basic Python world-rendering script is installed in /opt/demos/world.py.
  • Use cd /opt/demos; python2 world.py to try that Python 2.x works.
  • Use cd /opt/demos; python3 world.py to try that Python 3.x works.
  • The script outputs a world.png. You can use docker cp to look at it.
