This project helps to setup a DHCP, NFS qnd TFTP server in one Docker container instance. This toolset can be used in the Embedded world to boot a device through the network or for automated testing.
It eases the network configuration process and does not affect the Host environment.

This README does not explains how to write the DHCP, NFS and TFTP configurations. Please refer to specific document in the "Usefull links" section if needed.

First install Docker:

curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh
rm get-docker.sh
sudo usermod -aG docker $USER

Log out and log in.

You can configure your setup by editing:

• the env.conf file (port mappping configuration, NFS/TFTP directories)
• the DHCP configuration files in "./etc/dhcp/dhcpd.conf"
• the network interface in "./etc/network/interfaces"
• the NFS configuration in "./etc/exports" and the NFS version in "./src/entrypoint.sh".

By default the NFS files are stored in "./nfs", the tftp in "./tftp" and the DHCP config are empty.
Please complete the config file according to your use case.

Once you have edited the configuration files execute the following command to build the Docker image:

./setup.sh

Then launch the Docker container:

./run.sh
