+
+# Set permissions (Dokku container user)
+chown -R 32767:32767 /var/lib/dokku/data/storage/gorush
+```
+
+#### 3. Copy APNs Key to Server
+
+From your **local machine**:
+
+```bash
+scp /path/to/AuthKey_XXXXXX.p8 root@your-server:/var/lib/dokku/data/storage/gorush/certs/apns_key.p8
+```
+
+#### 4. Mount Certificate Directory
+
+```bash
+dokku storage:mount gorush /var/lib/dokku/data/storage/gorush/certs:/certs:ro
+```
+
+#### 5. Deploy Gorush
+
+```bash
 dokku git:from-image gorush appleboy/gorush:latest
+```
 
-# Set environment
+#### 6. Configure Gorush Environment
+
+```bash
 dokku config:set gorush \
   GORUSH_CORE_PORT=8080 \
   GORUSH_IOS_ENABLED=true \
+  GORUSH_IOS_KEY_PATH=/certs/apns_key.p8 \

-dokku storage:mount gorush /var/lib/dokku/data/storage/casera-api/certs:/certs:ro
-dokku config:set gorush GORUSH_IOS_KEY_PATH=/certs/apns_key.p8
+#### 7. Set Proxy Port
 
-# Update Casera API to point to Gorush
+```bash
+dokku proxy:ports-set gorush http:80:8080
+```
+
+#### 8. Restart Gorush
+
+```bash
+dokku ps:restart gorush
+```
+
+#### 9. Configure Casera API to Use Gorush
+
+```bash
 dokku config:set casera-api GORUSH_URL=http://gorush.web:8080
 ```
 
+#### 10. Verify Gorush is Running
+
+```bash
+# Check status
+dokku ps:report gorush
+
+# Check logs
+dokku logs gorush
+
+# Test health endpoint (if you have a domain set)
+curl http://gorush.yourdomain.com/api/stat/go
+```
+
 ### Option B: Use External Push Service
 
 Configure the app to use an external push notification service instead.
