Pull and run the image:

Prerender will now be running on http://localhost:3000. Try the container out with curl:
curl http://localhost:3000/render?url=https://www.example.com/
A few default plugins have been activated by default (see server.js):
- https://github.com/prerender/prerender/blob/master/lib/plugins/blacklist.js
- https://github.com/prerender/prerender/blob/master/lib/plugins/httpHeaders.js
- https://github.com/prerender/prerender/blob/master/lib/plugins/removeScriptTags.js
This can be modified by creating your own server.js and mounting this file as a docker volume:
docker run -p 3000:3000 -v $(pwd)/server.js:/home/node/server.js tvanro/prerender-alpine:6.6.1
The prerender-memory-cache plugin is not activated by default.
You can activate it with the environment variable MEMORY_CACHE=1.
You can customize cache behavior with environment variables :
- CACHE_MAXSIZE=1000 : max number of objects in cache
- CACHE_TTL=6000 : time to live in seconds
docker run -p 3000:3000 -e MEMORY_CACHE=1 -e CACHE_MAXSIZE=1000 -e CACHE_TTL=6000 tvanro/prerender-alpine:6.6.1
