Docker Expose Port 995

Expose Port 995 in Docker

docker run -p 995:995 your-image-name
		

This command maps container port 995 to the same port on the host machine.

Dockerfile Example

FROM node:18-alpine
WORKDIR /app
COPY . .
EXPOSE 995
CMD ["npm", "start"]
		

The EXPOSE instruction documents that the container listens on port 995.

EXPOSE vs Publish (-p)

• EXPOSE 995 documents the port inside the container.
• -p 995:995 makes the port accessible from the host.
• Exposed ports are not reachable unless published.

Docker Expose Port 995 Not Working

If Docker expose port 995 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 995 Already in Use

The error “port 995 already in use” means another process is already bound to that port on your host system.

# Find process using port 995
lsof -i :995

# OR use a different host port
docker run -p 8080:995 your-image-name
		

• Ensure your app is listening on port 995 inside the container
• Verify the port is published using -p
• Check firewall or network rules
• Avoid conflicts with existing services
