Connection refused on react docker container

Question

I'm new ro Docker, i'm trying to dockerize my react application - This is my Dockerfile:

FROM mhart/alpine-node:latest AS builder
WORKDIR /app
COPY . .
RUN npm install formik
RUN npm install axios
RUN yarn run build

FROM mhart/alpine-node
RUN yarn global add serve
WORKDIR /app
COPY --from=builder /app/build .
EXPOSE 8000
CMD ["serve", "-p", "80", "-s", "."]

• i build the container successfully:

docker build -t frontend .

• Then i run:

docker run 8000:80 frontend

• When i try to access to the server on:

localhost:8080

I get connection refused. I don't know what i did wrong, Any help is appreciated.

You should port forward with parameter -p, like:

docker run -p 8000:80 frontend
