Ubuntu – error in building a docker image from my react project

I followed this documentation to dockerize my react app and I did everything as it said, but I get this ERROR: failed to solve: circular dependency detected on stage: prod when try to execute docker image build -t react:v1 .

this is my Dockerfile (exactly as documentation)

FROM node AS prod
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
# RUN npm test - if you want to test before to build
RUN npm run build

FROM nginx:alpine AS prod
WORKDIR /usr/share/nginx/html
COPY --from=prod /app/build .
EXPOSE 80
# run nginx with global directives and daemon off
ENTRYPOINT ["nginx", "-g", "daemon off;"]

and this is .dockerignore

/node_modules

I’m also using Ubuntu on vmware workstation.

    If you use multi-stage builds, name’s stage must be unique in Dockerfile. prod was be used in 2 stages in your script, just change one of them

    FROM node AS prod # node-prod
...
FROM nginx:alpine AS prod # nginx-prod

    You have the same stage name for both the stages as this causes the circular dependency error.

    Change one of them

    FROM nginx:alpine AS prod

    into

    FROM nginx:alpine AS nginx-prod
