Can't connect to frontend in Dockerized React web app on MacOS – Nginx

I was recently hired on a website development project and I am having trouble deploying it via docker on MacOS. I just can’t connect to the frontend via localhost:8000.
I have temporarily solved this problem by running docker in a virtual machine (Ubuntu), but some things are not working correctly due to this connection.

What are the ways to solve this problem?

Here is the config in dockerfiles:

Dockerfile (frontend)

# pull official base image
FROM node:12-alpine as build


# create and set working directory
WORKDIR /app
# install app dependencies
RUN mkdir frontend
COPY package.json ./frontend/
COPY package-lock.json ./frontend/
COPY frontend_healthchecker.sh ./frontend/
RUN chmod +x /app/frontend/frontend_healthchecker.sh

RUN ls
RUN cd frontend && ls
RUN cd frontend && npm install --only=prod
# RUN cd frontend && npm install --scripts-prepend-node-path=auto

# add app code
COPY . ./frontend/
RUN cd frontend && ls

# start app
RUN cd frontend && npm install && npm run build

FROM nginx:1.16.0-alpine
COPY --from=build /app/frontend/build /usr/share/nginx/html
COPY --from=build /app/frontend/nginx/default.conf /etc/nginx/conf.d/default.conf

COPY --from=build /app/frontend/frontend_healthchecker.sh /home
RUN chmod +x /home/frontend_healthchecker.sh
RUN apk add curl
RUN apk search curl
HEALTHCHECK CMD ["/bin/sh", "/home/frontend_healthchecker.sh"]

EXPOSE  8000

CMD ["nginx", "-g", "daemon off;"]
