lab-cli

This is a simple tool to create libvirt VMs with a preseed/kickstart config from the network. It also configures a user ready for Ansible use. The goal with this small project is to get more familiar with programming.

Requirements

• Go
• libvirt (KVM/QEMU)
• virt-install

The user running lab-cli needs to connect to the system libvirtd instance. The easiest way is to add your user to the libvirt group.

You can test if this works by running this command as your user

$ virsh -c qemu:///system

Installation

Development files for libvirt is required to build the application (required by libvirt-go). The package is usually called libvirt-dev or something similar.

Example:

# openSUSE
$ zypper install libvirt-devel

# Debian
$ apt install libvirt-dev

The simplest way to install the application is to run

$ go get -u github.com/jagardaniel/lab-cli

It will install the lab-cli binary to $GOPATH/bin or $HOME/go/bin if the GOPATH environment variable is not set.

Configuration

Copy the config directory from the repository to $HOME/.config/lab-cli or $XDG_CONFIG_HOME/lab-cli if XDG_CONFIG_HOME is set.

$ ls /home/daniel/.config/lab-cli/
config.toml  templates

Usage

Create VM

Create a new Debian VM with the name lab01

$ lab-cli create lab01

Create a CentOS VM called lab02 with 20GB disk size and member of the Ansible groups webservers and dbservers

$ lab-cli create --distro centos --disk 20 --groups webservers,dbservers lab02

The installation takes a while to complete (~5 minutes) and the VM will shut down when the installation is finished. It should reboot after installation but... yeah, that doesn't right now. You can use a tool like virt-manager to see how the installation is going.

Remove VM

$ lab-cli remove lab01

List VMs

$ lab-cli list

Start or stop a VM

$ lab-cli stop web01
$ lab-cli start web02

SSH into a VM

$ lab-cli ssh web01
