# podman-standalone.sh — Turnstone rootful Podman setup (no Compose)
#
# For hosts running system Podman (non-rootless) with systemd.
# Turnstone is a diagnostic log intelligence layer — ingest service logs,
# search by symptom, and view incidents in a lightweight web UI.
#
# ── Prerequisites ────────────────────────────────────────────────────────────
#   1. Clone the repo:
#        sudo git clone https://git.opensourcesolarpunk.com/Circuit-Forge/turnstone.git /opt/turnstone
#        sudo chown -R x:x /opt/turnstone
#
#   2. Build the image (requires Docker or Podman with BuildKit/multi-stage support):
#        cd /opt/turnstone && podman build -t localhost/turnstone:latest .
#
#   3. Create data and custom patterns directories:
#        mkdir -p /opt/turnstone/{data,patterns}
#        # Optionally copy default patterns as a starting point:
#        cp /opt/turnstone/patterns/default.yaml /opt/turnstone/patterns/
#
#   4. Run this script:
#        bash /opt/turnstone/podman-standalone.sh
#
# ── After setup — generate systemd unit file ─────────────────────────────────
#   sudo podman generate systemd --new --name turnstone \
#     | sudo tee /etc/systemd/system/turnstone.service
#   sudo systemctl daemon-reload
#   sudo systemctl enable --now turnstone
#
# ── Ingesting logs ────────────────────────────────────────────────────────────
#   Log files on the host are bind-mounted read-only under /logs/ in the
#   container. To ingest (run manually or via cron):
#
#     podman exec turnstone python scripts/ingest_corpus.py \
#       /logs/qbittorrent/qbittorrent.log /data/turnstone.db
#
#   Example cron (every 15 minutes):
#     */15 * * * * podman exec turnstone python scripts/ingest_corpus.py \
#       /logs/qbittorrent/qbittorrent.log /data/turnstone.db >> /var/log/turnstone-ingest.log 2>&1
#
# ── Adding Caddy reverse proxy ────────────────────────────────────────────────
#   Add to /etc/caddy/Caddyfile:
#
#     turnstone.example-node.tv {
#       import protected
#       reverse_proxy 10.0.0.10:8534
#       import cloudflare
#     }
#
#   Then: sudo systemctl reload caddy
#
# ── Ports ────────────────────────────────────────────────────────────────────
#   Turnstone UI  → http://localhost:8534/turnstone/
#
set -euo pipefail

REPO_DIR=/opt/turnstone
DATA_DIR=/opt/turnstone/data
PATTERNS_DIR=/opt/turnstone/patterns
TZ=America/Los_Angeles

# ── Bundle push configuration ────────────────────────────────────────────────
# Set TURNSTONE_BUNDLE_ENDPOINT before running this script to enable the
# "Send Bundle" button in the Incidents UI:
#
#   export TURNSTONE_BUNDLE_ENDPOINT=https://turnstone.circuitforge.tech/turnstone/api/bundles
#   bash /opt/turnstone/podman-standalone.sh
#
# TURNSTONE_SOURCE_HOST is auto-detected from `hostname` — override if needed.

# ── Log source bind mounts ────────────────────────────────────────────────────
# Add or remove mount flags below for each service whose logs you want to ingest.
# Inside the container, paths appear under /logs/<service>/
#
QBIT_LOGS=/opt/qbittorrent/config/data/logs

# ── Turnstone container ───────────────────────────────────────────────────────
# Image is built locally — no registry auto-update label.
# To update: sudo podman build -t localhost/turnstone:latest /opt/turnstone
#            sudo podman restart turnstone
#
# Must be run as root (sudo bash podman-standalone.sh) — rootful Podman only.
#
# Remove existing container if present (safe re-run)
podman rm -f turnstone 2>/dev/null || true
