Why is port 3000 not opening - docker run --name node-con -it -p 3000:8080 avgona/node?

Question

Node.js

Why doesn't my server start on port 3000?

FROM alpine
VOLUME /home/server

WORKDIR /home/server

COPY ./ /home/server/

EXPOSE 8080

RUN apk add npm && npm i -g http-server 

CMD http-server

docker build -t avgona/node .
docker run --name node-con -it -p 3000:8080 avgona/node

On my localhost:3000 it gives - page not found
