simple container for tftp server

intended for use in greta wwulf nodes that don't have tftpd binary

docker pull ghcr.io/tin6150/tftpd:main docker run -it --rm --entrypoint /bin/bash tftpd:main

docker run -it -p 69:69/udp -v /global/sysbase/tftp/tftpboot:/tftpboot registry.greta.local:443/tftpd:main # this work, don't req full path from client

docker run -it -p 69:69/udp --entrypoint /usr/sbin/in.tftpd -v /global/tftpboot:/tftpboot registry:443/tftpd:main -L -vvv
^^ above worked, but tftp client need to specify full path fetched files

~/app/centos7/tftp s02 -c get /tftpboot/hello_world.txt

SERVER=s02 /usr/bin/tftp $SERVER -c get hello_world.txt # seems to work, but file saved inside container. so end up copying the binary to the host.

nc

singularity pull --name tftpd.sif docker://ghcr.io/tin6150/tftpd:main
