MediaWiki uses its custom Parsoid service as part of its new WYSIWYG, VisualEditor. This is a simple container to run an instance of it.

Example:

docker run
  -p 8000:8000
  -v ./data:/data
  benhutchins/parsoid

When you startup the container, it'll create a config.yaml file based on the example file from Parsoid.
