Docker LAN Server Setup Guide

To set up a server in a local area network, you can easily do so using Docker. Here are the steps for building a LAN server based on Docker.

1. Install Docker: Make sure Docker is installed on your host machine by following the official documentation.
2. Write Dockerfile: Create a Dockerfile specifying the base image to be used and the software to install, such as nginx, Apache, Node.js, etc.
3. Build the image: in the directory where the Dockerfile is located, execute the build command, for example: docker build -t myserver .
4. To run the container: Once it’s built, you can start the container by running the docker run command and specifying parameters such as port mapping and network. For example: docker run -d -p 80:80 –name myserver myserver
5. Set up the network: In order for other hosts on the local area network to access the server, the container’s port needs to be mapped to the host’s port. This can be achieved by specifying the -p parameter when running the container to map the container’s port to the host.
6. Set up the firewall: Ensure that the ports used by the containers are open if there is a firewall in place.

By following the steps above, you will be able to set up a server running in a Docker container on your local network. It is important to ensure that your server has a fixed IP address within the local network so that other hosts can easily access it.
