How can do multistage build with docker

[ahmetoruc1979]

I am trying to build log4brains in a multi-stage docker file. After the build operation, I am deploying static files to an Nginx. But, Adr's and some links are broken. Because in the output folder there is no folder with the name "l4b-static". I think the output folder has some differences.

The docker file is below:

FROM node:14.18-alpine3.14 AS builder
RUN npm install -g log4brains
ENV ADR_HOME=/opt/adr
WORKDIR /usr/src/app
COPY package.json ./
COPY tsconfig.json ./
RUN npm install
RUN npm install -g log4brains
WORKDIR ${ADR_HOME}
COPY docs ./docs
COPY .log4brains.yml ./
RUN log4brains build

FROM nginx:alpine
WORKDIR /usr/share/nginx/html
RUN rm -rf ./*
COPY --from=builder /opt/adr/.log4brains/out/* ./
ENTRYPOINT ["nginx", "-g", "daemon off;"]

I have deleted * from COPY --from=builder /opt/adr/.log4brains/out/* ./
The Last docker command is
COPY --from=builder /opt/adr/.log4brains/out/ ./
The statics have come exactly.
