In this post, I showed how to provision a Ubuntu VM using Vagrant and VirtualBox, now here is an updated version to provision as many as you want (and your hardware supports) within a single script.
Basically, the script is the same as before, the difference is that I’ve set some variables and moved the configuration part inside a loop.
# Define how many VMs you want to be provisioned
SERVERS = 3
# Specify the Network and which IP to be configured
IP_NETWORK = "10.200.200."
IP_START = 20
Vagrant.configure("2") do |config|
config.vm.box = "ubuntu/focal64"
(1..SERVERS).each do |i|
config.vm.define "server0#{i}" do |server|
server.vm.network :private_network, ip: IP_NETWORK + "#{IP_START + i}", virtualbox__intnet: "redenat"
server.vm.hostname = "server0#{i}"
server.vm.provider :virtualbox do |vb|
vb.customize ["modifyvm", :id, "--memory", 2048]
vb.customize ["modifyvm", :id, "--cpus", 4]
vb.customize ["modifyvm", :id, "--name", "server0#{i}"]
end
server.vm.provision "shell", inline: <<-'SHELL'
sed -i 's/^#* *\(PermitRootLogin\)\(.*\)$/\1 yes/' /etc/ssh/sshd_config
sed -i 's/^#* *\(PasswordAuthentication\)\(.*\)$/\1 yes/' /etc/ssh/sshd_config
systemctl restart sshd.service
echo -e "vagrant\nvagrant" | (passwd vagrant)
echo -e "root\nroot" | (passwd root)
apt-get update
SHELL
end
end
endAs before, let’s run vagrant up and see the magic happens, we will have 3 pre-configured servers in less than 5 minutes.
