Unable to run the node script in docker container

Question

I am trying to setup a node server on the docker container, I have created a Dockerfile with the following contents:

FROM node:15

WORKDIR /usr/src/appserver
COPY rdv.js rdv.js

RUN npm install
RUN npm install socket.io
RUN npm install peer

EXPOSE 9000 1500
CMD ["node", "rdv.js"]

Here is the sample rdv.js script:

var io = require('socket.io')(1500);
var PeerServer = require('peer').PeerServer;
var server = new PeerServer({port: 9000, path: '/myapp'});

....

I build the image and run the container using the following commands: < docker build -t nodeserver . < docker run nodeserver

but getting the errors while running the node server:

node:internal/modules/cjs/loader:927
  throw err;
  ^

Error: Cannot find module 'node:http'

  requireStack: [
    '/usr/src/appserver/node_modules/peer/dist/index.cjs',
    '/usr/src/appserver/rdv.js'
  ]
}

Any idea what I am missing here?

The node: prefix to import core modules were introduced in Node.js v16, while your Dockerfile is based on v15 (FROM node:15).
