+# Skip Migrations - Just Start Blockscout
+
+## Problem
+The `Explorer.Release.migrate()` function is not available in the eval context, causing the container to restart repeatedly.
+
+## Solution
+Since the database tables already exist (verified earlier), we can skip migrations and just start Blockscout directly.
+
+## Commands
+
+```bash
+cd /opt/blockscout
+
+# Update docker-compose.yml to just start (no migrations)
+python3 << 'PYTHON'
+with open('docker-compose.yml', 'r') as f:
+    lines = f.readlines()
+
+new_lines = []
+i = 0
+while i < len(lines):
+    line = lines[i]
+    # Check if this is a command line
+    if 'command:' in line:
+        indent = len(line) - len(line.lstrip())
+        # Replace with simple start command
+        new_lines.append(' ' * indent + 'command: bin/blockscout start\n')
+        i += 1
+        # Skip the list items (- sh, -c, etc.)
+        while i < len(lines) and lines[i].strip().startswith('-'):
+            i += 1
+        continue
+    new_lines.append(line)
+    i += 1
+
+with open('docker-compose.yml', 'w') as f:
+    f.writelines(new_lines)
+
+print("✅ Updated to just start (no migrations)")
+PYTHON
+
+# Verify
+grep -A 1 "command:" docker-compose.yml
+
+# Restart
+docker-compose down blockscout
+docker-compose up -d blockscout
+
+# Check status
+sleep 30
+docker ps | grep blockscout
+docker logs blockscout 2>&1 | tail -30
+```
+
+## Why This Works
+
+1. **Tables already exist**: We verified that `migrations_status`, `blocks`, and `transactions` tables exist
+2. **Migrations were run**: The tables wouldn't exist if migrations hadn't been run previously
+3. **Release module unavailable**: The `Explorer.Release` module is only available in certain contexts, not in regular eval
+
+## Alternative: If Migrations Are Needed Later
+
+If you need to run migrations in the future, you can:
+
+1. Use a one-off container:
+```bash
+docker run --rm \
+  --network host \
+  -e DATABASE_URL=postgresql://blockscout:blockscout@localhost:5432/blockscout \
+  blockscout/blockscout:latest \
+  bin/blockscout eval "Application.ensure_all_started(:explorer); Explorer.Release.migrate()"
+```
+
+2. Or connect to the running container and run migrations manually:
+```bash
+docker exec -it blockscout bin/blockscout remote
+# Then in the remote console:
+Explorer.Release.migrate()
+```
+
+But for now, since tables exist, just starting Blockscout should work.
