Running with Docker

Unfortunately Thumbor doesn't have an official Docker image it looks like, but there are some trusted unofficial images, in particular, the minimalcompact/thumbor image.

    environment:
      # VIRTUAL_HOST is picked up by nginx-proxy. Here it's set for localhost
      # but you usually need to point it to your domain, e.g. thumbor.example.com
      - VIRTUAL_HOST=localhost
      # THUMBOR_NUM_PROCESSES control how many processes run inside the container
      # Normally this is set in connection with the number of CPU cores
      # Note however that you can also use the docker-compose scale option to dynamically
      # scale your thumbor instances
      - THUMBOR_NUM_PROCESSES=4
      # this would allow CORS from any origin (you can restrict to specific origins if you want)
      - CORS_ALLOW_ORIGIN=*
      # returns a webp image if browser Accept headers match
      - AUTO_WEBP=True
      # nginx-proxy does caching automatically, so no need to store the result storage cache
      # (this greatly speeds up and saves on CPU)
