Debian unattended install
ATTENTION: this repo is focused on my thesis work so expect some mess and low generalization.
Usage
Get help:
./regeniso-sid.sh -h
Examples:
Note:
preseed/kube.cfg
at the moment works only with the netinst image. The reason is that with the netinst-minimal I should manually install some kernel modules (cdrom
for example) and at the moment I don't know how to do this.
Generate a netinst with a kube preseed:
./regeniso-sid.sh preseed/kube.cfg netinst stable amd64 auto "bluetooth.blacklist=yes bnep.blacklist=yes"
Initialize the VM
Create a VM and launch the unattended install.
Minimal requirements:
- 2 Cores
- 3GB RAM (8GB for a decent experience)
Once the unattended installation finished successfully we should prepare the environment inside the VM.
Launch this script:
/srv/custom/main.sh
Once it concluded successfully shut down the VM.
Use the image of the first VM as a base and create 3 different linked volumes:
qemu-img create -f qcow2 -b baseImage.qcow2 deltaImage.qcow2
Create 3 clones of the base VM and associate at each one a delta image. Beware that each VM must have a different MAC address.
Launch the 3 VM clones and in one of them (usually the first) login and then install Rancher:
Login without polluting the known hosts file:
ssh virtualuser@ipAddress -o "StrictHostKeyChecking=no" -o "UserKnownHostsFile=/dev/null"
And then launch this to install Rancher:
docker run -d --restart=unless-stopped -p 80:80 -p 443:443 --privileged rancher/rancher
