Dockerfile Expose: Example

EXPOSE 9000-9010/tcp

const http = require('http'); const port = 3000; const server = http.createServer((req, res) => res.end('Hello from inside the container!'); ); server.listen(port, () => console.log(`Server running on port $port`); ); Use code with caution. 2. The Dockerfile dockerfile expose example

# Publish to specific host port docker run -p 8080:3000 myapp EXPOSE 9000-9010/tcp const http = require('http')

CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "8000"] const port = 3000

: EXPOSE is metadata. Always use -p or -P when running containers to actually access the ports!
