Kubernetes

Prerequisites

• Ansible installed on your local machine. See Infrastructure as Code page.
• SSH access to the target machines where you want to install k3s.

Add SSH keys on local device

1. Copy private and public key (stored in Bitwarden Vault)

   cp /path/to/my/key/ansible ~/.ssh/ansible
   cp /path/to/my/key/ansible.pub ~/.ssh/ansible.pub
   

2. Change permissions on the files

   sudo chmod 600 ~/.ssh/ansible
   sudo chmod 600 ~/.ssh/ansible.pub
   

3. Make ssh agent to actually use copied key

   ssh-add ~/.ssh/ansible
   

Setting up VM hosts on Proxmox

1. Create a VM with the following partitions
   • / (10 GB) xfs
   • /var (50GB) xfs
   • /boot (1GB)

Note

No swap partition is needed for kubernetes

1. Login to the VM and set hostname.

   hostnamectl set-hostname <hostname>
   

2. Reboot.

3. Set static ip for the VM in the DHCP server.

4. Reboot.

5. Set this hostname in the ansible inventory hosts.yaml file.
