Quick notes on installing Ubuntu with LUKS+LVM2

These are just some quick notes about installing Ubuntu to an encrypted partition (LUKS) with LVM2 on top of it. The installer GUI has an advanced option to do this, but it is only available if you select the Erase disk and install Ubuntu option. I wanted to use this setup while preserving dual boot with Windows.

You should probably follow the following guide, instead of my instructions: https://help.ubuntu.com/community/Full_Disk_Encryption_Howto_2019

TODO

• Encrypt /boot partition (see the linked guide above).
• Fix Windows boot loader, removed from GRUB after last update-grub.

Get latest GitHub release

These snippets can be used to retrieve the latest GitHub release from Linux, macOS and Windows. Note that other approaches involve either:

• HTML scraping involving more dependencies or more complex code.
• Using GitHub API, which has rate limit, so it is not suitable for all applications.

Replace the repository org/name with yours.

Bash

#!/bin/bash
set -e

if [[ -z ${K8S_JVM_POD} ]]; then
    echo "K8S_JVM_POD not defined"
    exit 1
fi

EXEC="kubectl exec ${K8S_JVM_POD}"
CP="kubectl cp ${K8S_JVM_POD}"
