Dockerfile wrong directory. I don't know why

Question

Hello I am trying to run my react app on docker and I've encountered a problem! I am beginner at this topic so please help!

FROM node:16.13-slim
WORKDIR /app
RUN chown -R node:node /app
USER node
COPY --chown=node:node package.json yarn.lock /app/
RUN yarn install --frozen-lockfile
COPY --chown=node:node src /app
RUN yarn build
EXPOSE 3000
ENTRYPOINT [ "yarn", "start" ]

my file structure is something like this

Answer 1

COPY --chown=node:node public src /app

Add the command above, since the public directory is not under the src directory

By adding only the following command

COPY --chown=node:node src /app

You did not copy the public directory
