Packer templates

Usage

Clone the repository:

git clone https://github.com/guischulz/packer-templates

Change working directory to template sub-directory:

cd packer-templates\ubuntu-20.04

Build a machine image from the template in the repository:

packer build ubuntu-20.04.1-server-amd64.json

Configuration

You can configure each template to match your requirements by setting the following template user variables.

User Variable	Default Value	Description
cpus	4	Number of CPUs
disk_size	100000	Documentation
headless	true	Documentation
memory	8192	Memory size in MB
mirror	file://...	A URL of the mirror where the ISO image is available

By default the VirtualBox provider will setup a NAT network with port forwarding for HTTP and SSH.

Name	Protocol	Host-Port	Guest-Port
apache	TCP	80	80
ssh	TCP	22	22

Example

Build an Ubuntu 20.04 server image with a 10 GB hard disk, 2 GB memory and 1 CPU using the VirtualBox provider:

packer build -only=virtualbox-iso -var disk_size=10000 -var memory=2048 -var cpus=1 ubuntu-20.04.1-server-amd64.json

Know Problem: On Windows platform packer sometimes fails to halt and deregister the VirtualBox VM.

==> virtualbox-iso: Error detaching ISO: VBoxManage error: VBoxManage.exe: error: Failed to get a console object from the direct session (VBOX_E_INVALID_OBJECT_STATE)
==> virtualbox-iso: VBoxManage.exe: error: Details: code VBOX_E_VM_ERROR (0x80bb0003), component MachineWrap, interface IMachine, callee IUnknown
==> virtualbox-iso: VBoxManage.exe: error: Context: "LockMachine(a->session, LockType_Shared)" at line 336 of file VBoxManageStorageController.cpp

Workaround: Add option post_shutdown_delay to your packer command line arguments, e.g.

packer build -var post_shutdown_delay=2m ubuntu-20.04.1-server-amd64.json
