**Motivations:** - Docker services (bitcoind and mempool) were not starting automatically after reboot - Mempool API was unhealthy because it tried to connect to bitcoind before it was ready - No restart policy for bitcoind container - Restart script started mempool before bitcoind, causing connection errors **Root causes:** - Bitcoind container had no restart policy (restart: no) - Restart script started mempool before bitcoind - No wait for bitcoind RPC to be ready before starting mempool - No boot startup script for Docker services **Correctifs:** - Configured restart policy for bitcoind container: docker update --restart=always - Improved restart-services-cron.sh: - Start/restart bitcoind BEFORE mempool - Wait for bitcoind RPC to be ready (max 60s) before starting mempool - Detect if container is stopped (start) or running (restart) - Use 'docker compose up -d' for mempool instead of 'restart' - Created start-docker-services.sh: - Start bitcoind first - Wait for bitcoind RPC to be ready (max 120s at boot) - Start mempool after bitcoind - Logging to data/start-docker-services.log - Created docker-services.service: - Systemd service to start Docker services at boot - Runs after docker.service and network.target - Executes start-docker-services.sh **Evolutions:** - Automatic startup at boot: Docker services start automatically after reboot - Guaranteed startup order: Bitcoind always starts before mempool - Availability check: Wait for bitcoind to be ready before starting mempool - Restart policy: Bitcoind container restarts automatically if stopped - Better observability: Detailed logs for diagnosis **Pages affectées:** - data/restart-services-cron.sh: Improved startup order and availability checks - data/start-docker-services.sh: New boot startup script - data/docker-services.service: New systemd service for automatic startup - fixKnowledge/docker-services-boot-startup.md: Documentation of improvements
