Docker Expose Port 554

Expose Port 554 in Docker

docker run -p 554:554 your-image-name
		

This command maps container port 554 to the same port on the host machine.

Dockerfile Example

FROM node:18-alpine
WORKDIR /app
COPY . .
EXPOSE 554
CMD ["npm", "start"]
		

The EXPOSE instruction documents that the container listens on port 554.

EXPOSE vs Publish (-p)

• EXPOSE 554 documents the port inside the container.
• -p 554:554 makes the port accessible from the host.
• Exposed ports are not reachable unless published.

Docker Expose Port 554 Not Working

If Docker expose port 554 is not working, it is usually due to incorrect port publishing, an application not listening on the expected port, or a port conflict on the host machine.

Port 554 Already in Use

The error “port 554 already in use” means another process is already bound to that port on your host system.

# Find process using port 554
lsof -i :554

# OR use a different host port
docker run -p 8080:554 your-image-name
		

• Ensure your app is listening on port 554 inside the container
• Verify the port is published using -p
• Check firewall or network rules
• Avoid conflicts with existing services
