Docker is running only on Port 80-CodePudding

I am trying to run the docker image on Port 4000. But I am not able to run but able to run on Port 80. What I am doing here?

FROM node:latest as build
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build
FROM nginx:latest
COPY --from=build /usr/src/app/dist/admin /usr/share/nginx/html
EXPOSE 4200

And I am creating image from this command

docker build --pull --rm -f "DockerFile" -t admin1:v1 "."

And when I am running on port 80 then I am able to use

docker run --rm -d -p 4200:4200/tcp -p 80:80/tcp admin1:v1

But when I am running this command then I am not able to

docker run --rm -d -p 4200:4200/tcp -p 4000:4000/tcp admin1:v1

I have seen other questions online for the same question. But I am not able to fix my problem. Any suggestion will be of great help!

CodePudding user response：

You need to map the docker container port to the docker host port.

Try the following Command

docker run --rm -d -p 4200:4200/tcp -p 4000:80/tcp admin1:v1

The following is the extract from the Docker Documentation

-p 8080:80  Map TCP port 80 in the container to port 8080 on the Docker host.
