# - Bound to all interfaces (for remote k8s worker access)
# - Data persisted in named volume
# - AOF persistence enabled for durability
# - Password authentication required (set in /etc/vlog/redis.env)
#
# Security notes:
# - REDIS_PASSWORD must be set in /etc/vlog/redis.env
# - Generate a strong password: python -c "import secrets; print(secrets.token_urlsafe(32))"
# - Use firewall rules to limit access to trusted worker IPs
# - Clients must use: redis://:PASSWORD@host:6379 in VLOG_REDIS_URL
