# Scripts — DevOps Toolbox
|
|
|
|
|
|
|
|
|
|
|
|
A personal collection of Python scripts for deploying, monitoring, and
|
|
|
|
|
|
maintaining Linux systems. Every script is **idempotent** (safe to run
|
|
|
|
|
|
repeatedly), requires **no external dependencies** (stdlib only), and
|
|
|
|
|
|
ships with `--dry-run` where applicable.

|
|
## Quick Start
|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
git clone https://codeberg.org/petrbalvin/scripts.git && cd scripts
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
All scripts are standalone — run them directly:
|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
# Check your network (Linux or FreeBSD)
|
|
|
|
|
|
python3 network-diag.py
|
|
|
|
|
|
|
|
|
|
|
|
# Full system health report (Linux)
|
|
|
|
|
|
python3 system-diag.py
|
|
|
|
|
|
|
|
|
|
|
|
# Set up a new server
|
|
|
|
|
|
sudo python3 server-setup.py --dry-run
|
|
|
|
|
|
|
|
|
|
|
|
# Set up a development workstation
|
|
|
|
|
|
sudo python3 workstation-setup.py --dry-run
|
|
|
|
|
|
|
|
|
|
|
|
# Deploy vLLM (interactive model selection)
|
|
|
|
|
|
sudo python3 vllm-deploy.py
|
|
|
|
|
|
|
|
|
|
|
|
# Deploy the Zabbix monitoring stack
|
|
|
|
|
|
sudo python3 zabbix-deploy.py --dry-run
|
|
|
|
|
|
|
|
|
|
|
|
# Clean up old kernels and temp files
|
|
|
|
|
|
sudo python3 system-optimise.py --dry-run
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
Every script supports `--help` and `--version` without root privileges.
|
|
|
|
|
|
Use `--dry-run` to preview changes before applying them, and `--skip-*`
|
|
|
|
|
|
flags to skip individual sections.

## Notes
|
|
|
|
|
|
|
|
|
|
|
|
### Security
|
|
|
|
|
|
|
|
|
|
|
|
- **`vllm-deploy.py`** always protects the HTTPS endpoint with an API key.
|
|
|
|
|
|
Supply your own with `--api-key`, or let the script generate one — it is
|
|
|
|
|
|
stored in a root-only `EnvironmentFile` and printed once in the summary.
|
|
|
|
|
|
- **`zabbix-deploy.py`** accepts secrets via the environment variables
|
|
|
|
|
|
`ZABBIX_DB_PASSWORD` and `ZABBIX_ADMIN_PASSWORD` (preferred), or the
|
|
|
|
|
|
`--db-password` / `--zabbix-password` flags (visible in shell history).
|
|
|
|
|
|
The database password is never passed on any command line.
|
|
|
|
|
|
- **`workstation-setup.py`** verifies what it downloads: Bun is installed
|
|
|
|
|
|
from a pinned release with SHA-256 verification, uv comes from the
|
|
|
|
|
|
Fedora repositories, and Brave's GPG key is checked against known
|
|
|
|
|
|
fingerprints before import. Zed's installer is pinned but published
|
|
|
|
|
|
without checksums — the script says so loudly.
|
|
|
|
|
|
- **`system-diag.py`** only contacts a third-party service
|
|
|
|
|
|
(`icanhazip.com`) when you pass `--external-ip`.
|
|
|
|
|
|
|
|
|
|
|
|
### Platform support
|
|
|
|
|
|
|
|
|
|
|
|
- `network-diag.py` runs on Linux and FreeBSD. On FreeBSD older than 13
|
|
|
|
|
|
it falls back to the legacy `ping6` binary where available.
|
|
|
|
|
|
- `system-diag.py` is Linux-only (it reads `/proc` and `/sys`) and says
|
|
|
|
|
|
so clearly on other platforms.
|
2026-07-26 00:16:39 +02:00
|
|
|
|
- The deployment and maintenance scripts target Fedora, CentOS Stream and
|
|
|
|
|
|
openEuler (dnf4 and dnf5 are both handled).

## Development
|
|
|
|
|
|
|
|
|
|
|
|
No build step, no dependencies. Lint and format with Ruff
|
|
|
|
|
|
(configuration in `ruff.toml`, line length 100):
|
|
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
|
ruff check .
|
|
|
|
|
|
ruff format --check .
|
|
|
|
|
|
```
