Blockscout Migration Status

Date: December 23, 2025
Container: VMID 5000 on pve2 (192.168.11.140)
Status: WAITING FOR AUTO-MIGRATIONS


Current Status

Database State

  • Tables Count: 0 (empty database)
  • PostgreSQL: Running and healthy
  • Blockscout Container: Running
  • Migrations: Waiting for auto-migration on startup

Issue Analysis

Blockscout should automatically run database migrations when it starts for the first time. However, the database schema is still empty, indicating migrations haven't completed yet.

Possible Reasons:

  1. First startup takes time: Blockscout may take 3-5 minutes to complete all migrations
  2. Migration errors: Silent failures or errors preventing migrations
  3. Application startup order: Background workers may be starting before migrations complete

Next Steps

Blockscout should automatically migrate on first startup. Wait 3-5 minutes and then check:

# Check if tables were created
docker exec blockscout-postgres psql -U blockscout -d blockscout -t -c "SELECT count(*) FROM information_schema.tables WHERE table_schema = 'public';"

# Check Blockscout logs for migration status
docker logs --tail 100 blockscout | grep -i migration

# Test API endpoint
curl http://localhost:4000/api/v2/status

Option 2: Manual Migration (If Auto-Migration Fails)

If migrations don't run automatically after 5-10 minutes, we may need to run them manually. However, the typical approach is to let Blockscout handle it on startup.


Configuration

The Blockscout container is configured with:

  • DISABLE_INDEXER=true - Indexer disabled (reduces startup load)
  • DISABLE_WEBAPP=false - Webapp enabled
  • ECTO_USE_SSL=false - SSL disabled for database connection
  • POOL_SIZE=10 - Database connection pool size

Monitoring Commands

# Check container status
docker ps | grep blockscout

# Follow logs in real-time
docker logs -f blockscout

# Check database tables
docker exec blockscout-postgres psql -U blockscout -d blockscout -c "\dt"

# Test API
curl http://localhost:4000/api/v2/status

# Test HTTPS
curl -k https://localhost/health
curl -k https://explorer.d-bis.org/health

Expected Outcome

Once migrations complete, you should see:

  • Database tables created (100+ tables including blocks, transactions, addresses, schema_migrations, etc.)
  • Blockscout API responding with status
  • Web interface accessible at https://explorer.d-bis.org

Note: First-time startup and migration for Blockscout typically takes 5-10 minutes. Be patient and monitor the logs.
