# ── Security ────────────────────────────────────────────
|
||
|
||
# Secret key for signing JWT tokens. Use a long random string in production.
|
||
# Generate: openssl rand -hex 32
|
||
# Example: JWT_SECRET=a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6
|
||
JWT_SECRET=change-me-in-production

# Default: 24 (tokens expire after 1 day)

|
||
# ── Database ────────────────────────────────────────────
|
||
|
||
# PostgreSQL connection string (URL format).
|
||
# Format: postgres://<user>:<password>@<host>:<port>/<database>?sslmode=disable
|
||
# Default: postgres://postgres:postgres@localhost:5432/manifest?sslmode=disable

# ── Storage ─────────────────────────────────────────────
|
||
|

# Must be writable by the server process.

# Default: /var/ota/artefacts
|

# ── Download & Bandwidth Control ────────────────────────
|
||
|
||
# Maximum number of simultaneous download streams.
|
||
# Under 10 Mbps total bandwidth, each stream is throttled to
|
||
# ~BANDWIDTH_BPS / MAX_CONCURRENT_DOWNLOADS bytes/s.
|
||
# Default: 50
|
||
# Example: MAX_CONCURRENT_DOWNLOADS=30 (more conservative)
|
||
MAX_CONCURRENT_DOWNLOADS=50
|
||
|
||
# Per-connection bandwidth limit in bytes per second.
|
||
# The default (209715 ≈ 205 KB/s) keeps 50 concurrent streams
|
||
# at roughly 10 Mbps total (50 × 205 KB/s ≈ 10 MB/s).
|
||
# Default: 209715
|
||
# Example: BANDWIDTH_BPS=102400 (~100 KB/s per stream, ~5 Mbps total)
|
||
BANDWIDTH_BPS=209715
|
||
|
||
# ── Rate Limiting ───────────────────────────────────────
|
||
|
||
# Maximum API requests per second per client IP (token bucket).
|
||
# Burst capacity is 2× this value.
|
||
# Default: 100
|
||
# Example: RATE_LIMIT_RPS=50 (stricter, for constrained environments)
|
||
RATE_LIMIT_RPS=100
