The easiest way by far is downloading an existing dump from kiwix

Per example wikipedia_en_all_nopic_2024-06.zim is only 54GB since it only contains text. Then via docker you could use this compose file where you have your .zim files in the wikis volume:

services:
  kiwix:
    image: ghcr.io/kiwix/kiwix-serve
    container_name: kiwix_app
    command: '*'
    ports:
      - '8080:8080'
    volumes:
      - "/wikis:/data"
    restart: always

Theorically you can actually one of the wikipedia database dumps with mediawiki but I don’t known of any easy plug and play guide
