# Pad — Docker Compose environment example
#
# Copy to .env, fill in values, then run `docker compose up -d`.
#
# If you don't already have a POSTGRES_PASSWORD, generate one with:
#   openssl rand -base64 32
# …and paste it below. Docker Compose WILL refuse to start with the password
# missing; this is deliberate so a fresh deploy can never inherit a known-weak
# default credential.

# REQUIRED — PostgreSQL password for the `pad` user.
POSTGRES_PASSWORD=

# REQUIRED on Postgres — AES-256 encryption key for TOTP seeds and other
# sensitive fields. 64-character hex string (32 bytes). Pad will auto-
# generate one on SQLite deployments but refuses to on Postgres because
# multi-replica deployments would generate divergent keys and fail cross-
# instance decryption. Generate with:
#   openssl rand -hex 32
PAD_ENCRYPTION_KEY=

# OPTIONAL — Which host interface the Pad web UI publishes to.
# Default (loopback only) is the safest choice on a fresh install, because
# the bootstrap endpoint is reachable until the first admin is created.
#   127.0.0.1  → localhost only (default)
#   0.0.0.0    → every interface (LAN + internet if no firewall)
#   10.0.0.5   → bind to a specific LAN IP
# PAD_BIND_ADDR=127.0.0.1

# OPTIONAL — Redis auth (docker-compose.prod.yml only).
# If set, Redis starts with `--requirepass` and Pad connects with the password.
# REDIS_PASSWORD=

# OPTIONAL — Pad Cloud sidecar shared secret (cloud mode only).
# Comma-separated list supports rotation for INBOUND calls: pad accepts
# any listed secret when pad-cloud calls pad's admin endpoints.
# PAD_CLOUD_SECRET=

# OPTIONAL — Base URL pad uses to call pad-cloud back (reverse direction,
# e.g. Stripe cancel-customer when a user deletes their account). Required
# in cloud mode to cascade account deletion through to Stripe billing;
# without it, pad deletes local rows but never cancels the subscription.
# PAD_CLOUD_SIDECAR_URL=http://pad-cloud:7778

# OPTIONAL — Exact outbound secret pad sends on reverse calls. Use this
# during a cloud-secret rotation when pad-cloud is still validating against
# the OLD value: pin the outbound here so the reverse call matches, then
# roll pad-cloud, then unpin. When unset, pad falls back to the LAST entry
# of PAD_CLOUD_SECRET (the older rotation value).
# PAD_CLOUD_OUTBOUND_SECRET=

# OPTIONAL — Encryption key for sensitive fields (32-byte hex string).
# If unset, Pad stores 2FA seeds in plaintext — set this for production.
#   openssl rand -hex 32
# PAD_ENCRYPTION_KEY=

# OPTIONAL — Trusted reverse-proxy CIDRs. Only peers in these CIDRs may set
# X-Forwarded-For / X-Real-IP. Leave unset for direct-exposed deploys.
# PAD_TRUSTED_PROXIES=10.0.0.0/8,172.16.0.0/12

# OPTIONAL — Bearer token required to scrape /metrics. When unset, /metrics
# is reachable only from loopback (so a Prometheus on the same host keeps
# working without config); when set, every scrape must send
# "Authorization: Bearer $PAD_METRICS_TOKEN".
#   openssl rand -hex 32
# PAD_METRICS_TOKEN=

# OPTIONAL — Session IP-change policy.
# Default (unset) logs an ActionSessionIPChanged audit entry when a session
# presents a new client IP and updates the stored IP. "strict" additionally
# destroys the session and forces re-login. Strict mode breaks legitimate
# mobility (mobile roaming, VPN toggles, carrier NAT); enable only for
# high-sensitivity deployments.
# PAD_IP_CHANGE_ENFORCE=strict
