Setting up qemu VM using nix flakes

Did you know that it is rather easy to setup a VM to test your NixOs configuration?

Create simple flake:

# flake.nix
{
  inputs.nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";

Apple Virtualization NixOS ISO

Run NixOS ISO using Apple Virtualization framework (for example UTM)

  • local: Download ISO
    • 22.05 or build ISO: nix-build -A iso_minimal.aarch64-linux '<nixpkgs/nixos/release.nix>'
    • 22.11 Minimal 64-bit ARM
  • local: Mount hdiutil mount *.iso
  • local: Copy kernel and initrd: cp /Volumes/nixos-minimal-2?/boot/{Image,initrd} ..
  • local: Find and copy kernel params: less /Volumes/nixos-minimal-2?/EFI/boot/grub.cfg
  • local: Append console=hvc0 to params.
  • UTM: Create a new "drive". 16 GB is comfortable, 64 GB is plenty. Attach to your VM.
  • UTM: Attach the ISO.

A list of IAM actions which require iam:PassRole as of December 2020. Nested parameters are written with dot ('.') notation. Where there are multiple relevant parameters, they are separated by the pipe character ('|'). consult the AWS documentation on special cases - noted with an asterisk (most of them are "array of documents" type parameters).…

How to setup AWS lambda function to talk to the internet and VPC

I'm going to walk you through the steps for setting up a AWS Lambda to talk to the internet and a VPC. Let's dive in.

So it might be really unintuitive at first but lambda functions have three states.

  1. No VPC, where it can talk openly to the web, but can't talk to any of your AWS services.
  2. VPC, the default setting where the lambda function can talk to your AWS services but can't talk to the web.
  3. VPC with NAT, The best of both worlds, AWS services and web.

So what happens if you nuke your terraform state or have buckets that you want to manage using terraform ?
#
# Bucket doesn't exist yet, run terraform plan
#
$ terraform plan
