FRESHLY FORKED!

Work in progress!

fai

Code for Docker image of FAI Fully Automatic Installation 4.3.3. With this image you may create FAI ISO's for Trusted Builds.

• To use this image:

docker run --name fai --privileged -it ricardobranco/fai:4.3.3

• Inside the container you must run fai-setup:

fai-setup -vl

• When the command is finished you may exit the container and commit a new image for reuse:

docker commit fai fai-setup && docker rm -v fai

• Then you can use the fai-setup image with your FAI configuration:

docker run --name fai -v ~/fai:/srv/fai/config --privileged -it fai-setup

NOTE: There's an example FAI config in the faiconfig directory to create an ISO that installs Ubuntu 16.04 and Docker.

• Inside the container you must run the fai-mirror.sh script to create a suitable mirror:

fai-mirror.sh HOSTNAME

NOTE: The HOSTNAME argument must be already defined in faiconfig/class/50-host-classes.

• Validate the mirror with the checkpkgs.sh script to check its integrity:

checkpkgs.sh /tmp/mirror

• You may commit a new fai-mirror image or save the mirror with docker-cp:

`docker cp fai:/tmp/mirror mirror.HOSTNAME

• Edit the menuentry at /etc/fai/grub.cfg. Change the XXX host with the name of the host used on faiconfig/class/50-hosts-classes.

vi /etc/fai/grub.cfg

NOTE: Don't forget to also change the Grub user and password, which defaults to "fai".

• Inside the container, run the fai-cd.sh script to generate a FAI ISO:

fai-cd.sh HOSTNAME

• The ISO is /tmp/fai-full.iso. Use docker-cp to get it from the container:

docker cp fai:/tmp/fai-full.iso .

• At this point you may exit and remove the container.

• To reliably burn the ISO to an USB stick, use the burniso.sh script provided in the utils/ directory:

burniso.sh /tmp/fai-full.iso

NOTES:

• This image is based on Ubuntu 16.04 to create Ubuntu 16.04 ISO images. With minimal modifications (Dockerfile and fai/NFSROOT) it's possible to create Debian 7 & 8 images, as well as Ubuntu 14.04.

• With a bit of tweaking, it should be possible to setup a container as a FAI server over the network.
