Takeover
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/ubuntu:24.04-core-amd64-generic-master
cat <<'EOF' > config.yaml
#cloud-config
users:
- name: "kairos"
passwd: "kairos"
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.
