Prerender Alpine

Lightweight Prerender container built on Alpine Linux with Node and Headless Chromium.

  • Prerender 5.21.6
  • Chromium 132.0.6834.83
  • Node 22.13.1

Requirements

  • Docker

Usage

Pull and run the image:

docker pull tvanro/prerender-alpine:7.0.1
docker run -p 3000:3000 tvanro/prerender-alpine:7.0.1

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/

Prerender plugins

A few default plugins have been activated by default (see server.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:7.0.1

Prerender memory cache

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:7.0.1
