Proxmox Assign Bind Mount To Unprivileged Container

In order for the LXC container to have full access the proxmox host directory, a subgid is set as owner of a host directory, and an ACL is used to ensure permissions.

Bind Mount dataset to LXC

Add the following line to /etc/pve/lxc/<CT_ID>.conf

mp0:/mount/point/on/host,mp=/mount/point/on/lxc

Create group on host

In the default Proxmox configuration, unpriviliged container subgids will have the prefix "10" followed by the expected 4-digit gid.

Exposing a directory on the host machine to an LXC container

Log into the container and create an empty directory, this will be the mount point
Log out and stop the container.
Open to your container's config file
- For regular LXC containers: /var/lib/lxc/mycontainer/config
- For unprivileged LXC containers: $HOME/.local/share/lxc/mycontainer/config
Add a new line above the lxc.mount directive, that follows the format below. Substitute proper paths as necessary:
- lxc.mount.entry = /path/to/folder/on/host /path/to/mount/point none bind 0 0

Both of these paths are relative to the host machine.

What you need:

lots of RAM
Debian based distribution or any that supports booting from initramfs
mkinitramfs or a tool to build a new initramfs
some linux knowledge

Alpine Linux 🌲 K8s in 10 Minutes

Summary

This guide will allow you to deploy a fresh Alpine Linux install into a Kubernetes K8 cluster in less than 10 minutes.

Why ✨

I went to learn Kubernetes recently and I built a k3 cluster using Alpine in an hour or so, it was a great experience. I figured the next step would be K8s, but I found no material on K8s for Alpine. This guide is the result of my first pass and the incorporations of high quality notes from the contributers. Kubernetes 🦄 is awesome.

Creating an Access Point on Raspberry Pi running Alpine Linux

By: XtendedGreg as seen on https://youtube.com/live/Uagq3oZrk6k

Introduction

Creating an access point with Alpine Linux on a Raspberry Pi can be an excellent project, as it allows you to extend your network or even create a new wireless network in a location where only wired internet is available. Below is a procedure to help you set up your Raspberry Pi as an access point using Alpine Linux. This guide assumes you have basic knowledge of Linux commands and networking.

Equipment Needed

Raspberry Pi (any model with Wi-Fi capability, e.g., Raspberry Pi 3/4/5)
MicroSD card (8 GB or more recommended)
Power supply for Raspberry Pi

AlpineLinux with wlan settings.

Install necessary drivers and software

First make sure your wireless drivers are loaded properly.
Install wpa_supplicant & dhcpcd.

apk add wpa_supplicant dhcpcd

Configuration
