A command-line tool for setting up and operating a home server cluster, including its Kubernetes installation. A cluster is a group of computers managed as one system.

Use it to create inventory, test machine reachability, install k3s, retrieve configuration, check application health, back up secrets, and run Ansible playbooks.

It gives developers a documented command map and ensures the repository's configured Python and Ansible environment is used. This reduces mistakes from running the wrong tools or commands.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00052	$0.00456
Opus 5	$0.00026	$0.00228
Sonnet 5	$0.00010	$0.00091
Haiku 4.5	$0.00005	$0.00046

Security

Grade B, and why

homelab-cli scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

What it actually says

Homelab CLI

How to run

Always from the repo root, through uv:

uv run homelab --help
uv run homelab -K ping
uv run ansible-playbook site.yml

Do not use a system ansible if .venv exists. docs/cli.md is the human reference.

Command map

User intent	Command
Create inventory	`uv run homelab setup --profile single` or `--profile cluster`
Reachability	`uv run homelab ping`
First k3s install	`uv run homelab bootstrap`
Kubeconfig	`uv run homelab kubeconfig`
Health	`uv run homelab status`
Off-cluster AWS backup	`uv run homelab backup-secrets` (see `docs/secrets-off-cluster.md`)
Named playbook	`uv run homelab playbook <name>`
Extra Ansible args	`uv run homelab playbook site.yml -- --limit controllers`

Playbook shortcuts: site, prep, install, longhorn-prereqs, status.

Destructive playbooks

Never wrap these in homelab bootstrap. Run the playbook only when the user typed the confirm string in this turn:

cluster-shutdown.yml needs -e confirm=SHUTDOWN
k3s-node-remove.yml needs -e confirm_remove=true

Prefer uv run ansible-playbook ... so the confirm extra-vars are obvious.

Inventory

File: ./inventory.ini (gitignored)
Examples: inventory.ini.example, inventory.ini.single.example
Do not commit it. Do not paste sudo passwords into it.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

homelab-cli is a skill published in the GitHub repository AndresJejen/beitlab_home_lab_cluster (5 stars, last pushed 11d ago), licensed MIT. It adds 52 tokens to every session and 456 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
