Setup

Configure Hosts

1. Install Proxmox.

2. Create user.

   apt update
   apt install sudo
   useradd -m mchill
   passwd mchill
   echo "mchill ALL=(ALL) NOPASSWD: ALL" | tee -a /etc/sudoers.d/mchill

3. Add ssh key from GitHub.

   mkdir ~/.ssh
   touch ~/.ssh/authorized_keys
   chmod 700 ~/.ssh
   chmod 600 ~/.ssh/authorized_keys
   wget -O - https://github.com/mchill.keys >> ~/.ssh/authorized_keys

4. Configure the hosts with Ansible.

   ansible-playbook playbooks/configure_proxmox_hosts.yaml -i inventory.yaml --extra-vars "@variables.yaml"

5. If Ceph was installed for the first time, some values need to be replaced.

   • Replace the clusterID with the result of ceph fsid in:

     • k8s/applications/wave1/ceph-csi-rbd.yaml
     • k8s/sources/shared/storage/pv.yaml

   • Replace the userKey with the result of ceph auth get-key client.k8s in:

     • k8s/sources/shared/storage/secret.yaml

Provision Virtual Machines

When creating VMs for the first time, set initialize=true to add the bootable CD and exclude devices that interfere with the OS installation process.

terraform apply -var="initialize=true"

Install Operating System

1. Install Ubuntu Server 24.04. Keep defaults except where noted below.

   1. Disable "Set up this disk as an LVM group"
   2. Enable "Install OpenSSH server"
   3. Import SSH key from GitHub

2. Reapply terraform configuration, removing the bootable CD and adding PCI and serial devices.

   cd terraform
   terraform apply

3. Enable passwordless sudo to allow Ansible to run later.

   echo "mchill ALL=(ALL) NOPASSWD: ALL" | sudo tee -a /etc/sudoers.d/mchill

Configure Virtual Machines

cd ansible
ansible-playbook playbooks/configure_proxmox_vms.yaml -i inventory.yaml --extra-vars "@variables.yaml"
