# Homelab Nomad
|
|
|
|
My configuration for creating my home Nomad cluster and deploying services to it.
|
|
|
|
This repo is not designed as general purpose templates, but rather to fit my specific needs. That said, I have made an effort for things to be as useful as possible for someone wanting to use or modify this.
|
|
|
|
## Running
|
|
|
|
make all
|
|
|
|
## Design
|
|
|
|
Both Ansible and Terraform are used as part of this configuration. All hosts must be reachable over SSH prior to running any of this configuration.
|
|
|
|
To begin, Ansible runs a playbook to setup the cluster. This includes installing Nomad, bootstrapping the cluster and ACLs, setting up NFS shares, creating Nomad Host Volumes, and setting up Wesher as a Wireguard mesh between hosts.
|
|
|
|
After this is complete, Nomad variables must be set for services to access and configure correctly. This depends on variables to be set based on the sample file.
|
|
|
|
Finally, the Terraform configuration can be applied setting up all services deployed on the cluster.
|
|
|
|
The configuration of new services is intended to be as templated as possible and to avoid requiring changes in multiple places. For example, most services are configured with a template that provides reverse proxy, DNS records, database tunnels, database bootstrapping, metrics scraping, and authentication. The only real exception is backups, which requires a distinct job file, for now.
|
|
|
|
## What does it do?
|
|
|
|
* Nomad cluster for scheduling and configuring all services
|
|
* Blocky DNS servers with integrated ad blocking. This also provides service discovery
|
|
* Prometheus with autodiscovery of service metrics
|
|
* Loki and Promtail aggregating logs
|
|
* Minitor for service availability checks
|
|
* Grafana providing dashboards, alerting, and log searching
|
|
* Photoprism for photo management
|
|
* Remote and shared volumes over NFS
|
|
* Authelia for OIDC and Proxy based authentication with 2FA
|
|
* Sonarr and Lidarr for multimedia management
|
|
* Automated block based backups using Restic
|
|
|
|
## Step by step
|
|
|
|
1. Update hosts in `ansible_playbooks/ansible_hosts.yml`
|
|
2. Update `ansible_playbook/setup-cluster.yml`
|
|
1. Update backup DNS server
|
|
2. Update NFS shares from NAS
|
|
3. Update volumes to make sure they are valid paths
|
|
3. Create `ansible_playbooks/vars/nomad_vars.yml` based on the sample file. TODO: This is quite specific and probably impossible without more documentation
|
|
4. Run `make all`
|
|
5. Update your network DNS settings to use the new servers IP addresses
