My homelab kubernetes infrastructure

Terraform definition for my cluster via KVM and libvirt

Overview

Nodes in KVM using libvirt

Requirements

• Terraform 0.12
• Terraform Plugin libvirt terraform provider
• libvirt 1.2.14 or newer development headers
• mkisofs to create the cloudinit iso
• A host ready for kvm and libvirt

On mac you can get get ready with this steps

brew install terraform libvirt cdrtools
./install_libvirt_terraform_provider.sh

Prepare the host

• On Ubuntu distros SELinux is enforced by qemu even if it is disabled globally, this might cause unexpected Could not open '/var/lib/libvirt/images/<FILE_NAME>': Permission denied errors. Double check that security_driver = "none" is uncommented in /etc/libvirt/qemu.conf and issue sudo systemctl restart libvirt-bin to restart the daemon on your host.
• You need to be able to connect to the host via ssh using a public key

Create the nodes

export TF_VAR_virt_host=<your_host_hostname_or_ip>
terraform init
terraform plan
terraform apply
