How can I host playground of my custom module as a documentation page?

Hello guys,
I have developed Nuxt Module as a component set. I would like to use playground project of module as a documentation web page. That's why I implemented Nuxt Content into the playground project. When I use npm run dev everything works fine but when I try to host via docker file I could not see my block components in the markdown page which are located /playground/components/content. Why it can be happened?

FROM node:18-alpine

RUN apk update && apk upgrade

RUN mkdir -p /app
WORKDIR /app

COPY . .
RUN npm install
RUN npm run dev:prepare
RUN npm run dev:build

EXPOSE 3000

ENTRYPOINT [ "node", "playground/.output/server/index.mjs" ]

I solved my problem. The reason of my problem Nuxt Content shikiji npm package. Aim of this package that setting color of the code parts in markdown file. I guess my project could not install correctly. In this case I tried "npm i --force" or "npm i --legacy-peer-deps". Both of them works for my case.
