TFTPD

Description

This project contains the configuration to create a docker image of the tftpd service.

Pre-Requirements

Packages

docker
docker compose

Directories and files

/tftpboot
/var/log/tftpd.log

Installation

Generate the configuration file from docker-compose.yml located in this project and modify the following parameters:

• image: Locates the tag where the most up-to-date image is located.
• volumes: Volumes contain the path of the files necessary for correct operation ("/tftpboot and /var/log/tftpd.log")

To download the project image, run in the path where the docker-compose.yml file is located:

PGID=$(id -g) PUID=$(id -u) docker-compose up -d

Note: If you'd like to override the UID and GID of the tftpd process, you can do so with the environment variables PUID and PGID. This is helpful if other containers must access your configuration volume.

Running the tests

Perform a GET or PUT method query through the tftp client and verify that the file was copied correctly.

GET method

tftp -v 172.20.0.2 69 -c get Spanish.txt Spanish-local.txt

PUT method

tftp -v 172.20.0.2 69 -c put Spanish-local.txt Spanish.txt

Note: Remember that to perform the PUT method the file must exist on the /tftpboot shared volume. If you want to create a file, add the following line in your docker-compose.yml

command: ["/usr/sbin/in.tftpd", "-c", "-L", "-v", "-s" , "-u", "tftpd", "/tftpboot"]

The -c flag allows you to create new files in case they do not exist.
