|---|---|
| Service or container does not start | Inspect compose configuration, dependency health, file permissions and the first fatal log line instead of repeatedly restarting. |
| Domain opens but HTTPS fails | Check A/AAAA records, ports 80/443, proxy mode, certificate challenge and conflicting reverse proxies. |
| Application cannot reach its database or queue | Use the internal service hostname, verify credentials and health checks, and keep database ports off the public interface. |
| Works initially but fails under load | Measure memory peaks, disk latency, connection pools and worker concurrency; increase capacity only after identifying the bottleneck. |
Yes after secrets are replaced, public access is restricted and a complete restore test has succeeded.
Minimums only prove the software can start. Size CPU, memory, IOPS and storage from representative workload measurements.
Yes. Use Full (strict) TLS and configure origin certificates, WebSockets and client IP forwarding where required.
Do not automatically apply major releases. Review migrations, back up data and retain the previous tested image.
Back up databases, uploaded files, persistent volumes, configuration, encryption keys and the deployed version together.
An NVMe VPS fits normal web workloads. Inference, accelerated OCR and video transcoding may require a compatible GPU.
