Packer templates to build Ubuntu LTS Virtualbox images with root ssh login, that can be used as starting point for VPS used in production.
This repository is based on kaorimatz/packer-templates. The main idea was to take vagrant packer script and remove insecure vagrant keys from it. I also removed all unneeded files as i wanted to focus on ubuntu images.
Clone the repository:
$ git clone https://github.com/jeff1985/packer-templates && cd packer-templates
Build a machine image from the template in the repository:
$ packer build -only=virtualbox-iso -var 'ssh_password=XXX' ubuntu-14.04_amd64.json
I recommend to create a separate yaml file containing ssh_password and run it like this:
$ packer build -only=virtualbox-iso -var-file=../packer.passwords.yml ubuntu-14.04_amd64.json
You can configure each template to match your requirements by setting the following user variables.
| User Variable | Default Value | Description |
|---|---|---|
compression_level |
6 | Documentation |
cpus |
1 | Number of CPUs |
disk_size |
40000 | Documentation |
headless |
0 | Documentation |
memory |
512 | Memory size in MB |
mirror |
A URL of the mirror where the ISO image is available | |
ssh_password |
xxx | The ssh password for the root user to be set. |
Build an uncompressed Arch Linux vagrant box with a 4GB hard disk using the VirtualBox provider:
$ packer build -only=virtualbox-iso -var compression_level=0 -var disk_size=4000 ubuntu-14.04_amd64.json
It is common for VPS boxes to have ssh root login enabled in their initial state. Make sure to enable ssh key auth when you start using the server:
$ ssh-copy-id root@vps
$ ssh "root@vps" "sed -i 's/PermitRootLogin.*/PermitRootLogin no/g' /etc/ssh/sshd_config; service ssh restart"
