Ewe Infra

Infrastructure repository for booting up a working service infrastructure for deployment applications into. Built on top of kubernetes, gitea and gitops principles.

Setup

Vaulted Secrets

Within this playbook are ansible-vault encrypted files which require a secret, this should be placed in the secrets.txt file in the root of the repository.

Place your text within the secrets.txt and run desired playbooks.

Copy inventory.example.yml file and add your target servers

cp inventory.example.yml inventory.yml

Execute

Install VPS KVM Setup

The vps_kvm playbook will setup 3 controllers and 3 worker microvms using ignite and firecracker provisioning for you a ready environment for use in setting up whatever services you wish to setup. We reuse this for setting up k0s

make deploy_play FILE=vps_kvm EXTRA_VARS=""

e.g

make deploy_play FILE=local_llm EXTRA_VARS="vps_host='metal_slaves'"

Goal:

1. Install containerd binary from its GitHub release.
2. Install firecracker binary from its GitHub release.
3. Install Weave Ignite binary from its GitHub release.
4. Use WeaveIgnite to set up 3 microvm as controller nodes (goal for setup k0s via the vps_k0s and generated custom host files).
5. Use WeaveIgnite to set up 3 microvm as worker nodes (goal for setup k0s via the vps_k0s and generated custom host files).
6. Generate a new custom inventory file containing host IPs and details for controllers and worker nodes.

Extra Information

Ansible has varying plugins for dynamic inventories:

ansible.builtin.auto                                    Loads and executes an inventory plugin specified in a YAML config
