# Debian unattended install |
||||||
|
|
||||||
|
> **ATTENTION:** this repo is focused on my thesis work so expect some mess and low generalization. |
||||||
|
|
||||||
|
## Usage |
||||||
|
|
||||||
|
Get help: |
||||||
|
|
||||||
|
```sh |
||||||
|
./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: |
||||||
|
|
||||||
|
```sh |
||||||
|
./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: |
||||||
|
|
||||||
|
```sh |
||||||
|
/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: |
||||||
|
|
||||||
|
```sh |
||||||
|
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: |
||||||
|
|
||||||
|
```sh |
||||||
|
ssh virtualuser@ipAddress -o "StrictHostKeyChecking=no" -o "UserKnownHostsFile=/dev/null" |
||||||
|
``` |
||||||
|
|
||||||
|
And then launch this to install Rancher: |
||||||
|
```sh |
||||||
|
docker run -d --restart=unless-stopped -p 80:80 -p 443:443 --privileged rancher/rancher |
||||||
|
``` |
