Load-balanced libreddit deployment

Use KVM/QEMU, Docker, libvirt, Terraform, and Ansible to deploy loadbalanced libreddit and verify deployment with Testinfra.

Dependencies

  1. GNU/Linux host machine
  2. KVM
  3. QEMU
  4. Libvirt
  5. Terraform
  6. Python 3
  7. Ansible
  8. Testinfra
  9. Debian 11 Bullseye qcow2 bootable

Usage instructions

1. Provision resources (VMs) on KVM using Terraform

  1. Generate and verify deployment plan
terraform plan -out=libreddit
  1. Apply deployment plan
terraform apply "libreddit"

2. Verify VMs are reachable from host

make configure.ping

3. Configure VMs

make configure

4. Test deployment

make test

5. Take down deployment

terraform destroy
