home-network

A reboot of an old project from about 7 years ago, https://github.com/CraigJPerry/home-network - I lost access to that github account after an unfortunate mistake with 2FA :-)

Instructions

  1. Install Ansible on the bootstrap host (a WSL2 VM in my case) pip3 install --user ansible
  2. Configure the host details in hosts
  3. Read the comments in bootstrap.yml and decide which strategy you'll run
  4. E.g. to install on nas i did, as root, ansible-pull -U https://github.com/craigjperry2/home-network -i localhost, # localhost only matches the bootstrap playbook

Pets or Cattle

Some notes to remind me of the rare occassions i treated a box as a pet.

  • FreeBSD 13.0 NAS (nas.home.craigjperry.com)
    • BIOS Setup
      • Enable all 6 HDDs as boot disks - if one drive fails, the bootloader is installed on the other 5
      • Enable low power states and bios fan speed control (workaround weird half-supported acpi/i2c)
      • When power is restored, always power-on
    • Bare metal install (was not PXE installed - NIC/BIOS doesn't support it)
      • Install from USB, FreeBSD standard 1G image (not the minimal one), selections:
        • UTC clock
        • Guided ZFS on root: select all 6 drives, raidz2 scheme, 4G swap per drive, 24G(!) total swap
        • Default 3 partition scheme on all HDDs:
          • p1: 512k, stage 1 boot loader
          • p2: 4G, swap (choose non-mirrored to permit crashdumps)
          • p3: 2.7-3.6Tb depending on disk, ZFS
        • Services
          • sshd
          • ntpdate (on boot)
        • Create "craig" user, additionally a "wheel" member
        • Selective hardening:
          • Clear /tmp on boot
    • Initial boot / post-install setup
      • freebsd-update fetch
      • freebsd-update install
      • pkg update
      • pkg upgrade
      • pkg install -y sudo neovim zsh zsh-completions git python37 py37-ansible
      • python3.7 -m ensurepip
      • python3.7 -m pip install -U pip
      • neovim setup:
      • nnn build & install:
        • gmake O_NERD=1 CPPFLAGS="-I/usr/local/include -DNERD" LDFLAGS=-L/usr/local/lib
        • sudo gmake install
      • Install rust toolchain https://rustup.rs/
        • cargo install --locked fd-find ripgrep xsv deno bat du-dust

TODO

Evolve the setup here.

Define Pre-requisites:

  • Host configured (IP, hostname, disk layout, etc.)
  • Package manager installed (e.g. homebrew, chocolatey)

Host added to inventory file with metadata for:

  • [Default] user-only (e.g. MacOS, WSL2) will not install ansible pull, push on demand only
  • full-system (e.g. Fedora, FreeBSD, etc.) will install ansible pull

Steps performed by Ansible:

Assume non-privileged user by default

  1. Install core user tools (e.g. git, zsh, nnn, fzf, tmux, neovim)
    1. when MacOS use Homebrew names for packages
    2. when Fedora use DNF names for packages
  2. when full-system metadata tag is present, setup required users:
    • ansible
    • craig
  3. when full-system metadata tag is present, maintain ansible pull
