Takeover
Learn how to enable Trusted Boot support in Kairos, which combines FDE, Secure Boot, and Measured Boot to protect your system from tampering and cold attacks.
Kairos supports takeover installations. Here are a few summarized steps:
- From the dedicated control panel (OVH, Hetzner, etc.), boot in rescue mode
- Install docker and run for example:
export DEVICE=/dev/sda
export IMAGE=quay.io/kairos/@flavor:@flavorRelease-core-amd64-generic-master
cat <<'EOF' > config.yaml
#cloud-config
users:
- name: "kairos"
passwd: "kairos"
groups:
- admin
ssh_authorized_keys:
- github:mudler
EOF
export CONFIG_FILE=config.yaml
docker run --privileged -v $PWD:/data -v /dev:/dev -ti $IMAGE kairos-agent manual-install --device $DEVICE --source dir:/ /data/$CONFIG_FILE
Note
--source flag refers to the source of installation. If you want to install from the pulled docker image you can set the --source flag to dir:/ to use the root dir of the image as install source. Otherwise you can point it to an oci image with the oci: prefix.- Switch back to booting from HD and reboot.
