packer-ubuntu

Packer template that builds Ubuntu (default 25.10) for amd64 with VMware Fusion on macOS.

Prerequisites

• macOS with VMware Fusion
• Packer >= 1.7.0

Building

1. Optional: override build variables by copying the example and editing:

   cp ubuntu.auto.EXAMPLE.hcl ubuntu.auto.pkrvars.hcl

   Edit ubuntu.auto.pkrvars.hcl (password hash, ssh_key, hostname, fusion_app_path, etc.). Generate a password hash with:

   openssl passwd -6 -salt $(openssl rand -hex 4) 'yourpassword'

2. Build:

   make

   Or without the Makefile:

   packer init .
   packer build .

   With a var file:

   packer build -var-file=ubuntu.auto.pkrvars.hcl .

3. Output: VM is in output/vmware-iso_25.10/ (path depends on os_version).

Cleanup

Stop the VM (if running) and remove the build output:

make clean

What the build does

• Cloud-init (files/user-data.pkrtpl): user, hostname, SSH key, password.
• Provisioning (scripts/configure.sh): installs open-vm-tools, then chezmoi with the trodemaster config, then cleanup.

Other config (dotfiles, packages) comes from the chezmoi setup, not from this repo.
