The Rocky Linux Vagrant VirtualBox image only provides a 5GB hard disk. As per the Vagrant documentation:
make sure the user will have enough disk space to do interesting things, without being annoying. For example, in VirtualBox, you should create a dynamically resizing drive with a large maximum size.
I’m assuming this was mistake considering there’s not enough space to install Docker engine.
I suggest using a dynamic disk set to a large size such as 100GB or more.
For comparison, the official CentOS image provides 40GB of space while the Alpine Linux image provides 13GB of space. Not sure why they artificially limit the drive size when using dynamic disks.
Is this the proper place for a bug report regarding the Vagrant boxes? If there’s a dedicated bug tracker let me know and I can submit this issue there instead.
Just a thought, is it really necessary to modify the disk included in the image? If you are using it in a Vagrant setup where you need X GB of disk, cant you just add a secondary disk and mount it somewhere when the machine is bootstrapped?
In this example, it looks like you can do something like:
disk = './secondDisk.vdi'
(...)
iscsitarget.vm.provider "virtualbox" do |vb|
unless File.exist?(disk)
vb.customize ['createhd', '--filename', disk, '--variant', 'Fixed', '--size', 20 * 1024]
end
The recommended disk size is 20GB so I agree that it should be increased, and I think RHEL recommendations is a good place to start now and in the future.
Aside from reasonable discussion of what the default disk size should be for Rocky Linux Vagrant images the latest version of Vagrant has experimental support for resizing/adding machine disks, including the machine primary disk.
With a small amount of extra configuration in the Vagrantfile the / (root) filesystem can be resized online.
There will invariably be use cases where more disk space than the default, whatever it may be, will not be enough. For those cases here is an example of how to do this…
Vagrantfile
% cat Vagrantfile
# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.configure("2") do |config|
config.vm.box = "rockylinux/8"
# Disable default shared_folder
config.vm.synced_folder ".", "/vagrant", disabled: true
# Resize primary disk, REQUIRES: VAGRANT_EXPERIMENTAL="disks" vagrant up
config.vm.disk :disk, size: "36GB", primary: true
config.vm.provider "virtualbox" do |vb|
# Display the VirtualBox GUI when booting the machine
vb.gui = true
# Customize the amount of memory on the VM:
vb.memory = "1024"
end
config.vm.provision "shell", inline: <<-SHELL
printf "\nDisk free space before...\n"
df -lhT /
printf "\nResizing / partition live with sgdisk...\n"
dnf install -y gdisk
sgdisk -g -e /dev/sda
sgdisk -d 1 /dev/sda
sgdisk -N 1 /dev/sda
partprobe /dev/sda
xfs_growfs /dev/sda1
printf "\nDisk free space after...\n"
df -lhT /
SHELL
end
