docker Timeline - FediScanner

Đóng gói BuildKit cho RISC‑V64 thành công nhưng container không chạy: lỗi “denied” do cache credential, crash “no worker found” vì thiếu runc, ENTRYPOINT/CMD sai khiến Buildx không truyền tham số, thiếu OCI worker. Sửa: docker logout → docker pull, chuyển CMD, cài runc (apt), sửa typo repo, thêm timeout cho CI, cập nhật tài liệu. Giờ BuildKit container hoạt động với Buildx. #BuildKit #RISC_V #Docker #CI #Debug #XâyDựng #Container

Kubernetes: Die Orchestrierung für moderne Anwendungen

Warum du Kubernetes kennen solltest Kubernetes ist ein Open-Source-System zur Orchestrierung von Containern, das dir als Systemadministrator hilft, Anwendungen skalierbar und zuverlässig im Produktionsbetrieb zu betreiben. Du solltest es kennen, weil es Container-Deployments automatisiert und die Komplexität von verteilten Systemen reduziert – essenziell für Cloud-Umgebungen auf Linux-Basis. Obwohl Kubernetes nicht direkt im RHCSA-Exam vorkommt, baut es auf Linux-Kenntnissen wie […]

🚀 Thử nghiệm Chaos Engineering: Đánh chết DB trong test để kiểm tra khả năng phục hồi UI. Dùng Python, Playwright + Docker SDK, dừng container Postgres, xác nhận toast “Connection lost” và nút retry hiện ra, rồi khôi phục. Giúp QA phát hiện lỗi kiến trúc, không chỉ chức năng. #ChaosEngineering #QA #Testing #Playwright #Docker #KiểmThử #KỹThuậtHỗnLoạn

Shipped BuildKit for RISC-V64. Green CI, packages built. Users tried it: crash loop.

"No worker found" - missing runc, wrong ENTRYPOINT/CMD, hanging tests.

Lessons:
✓ Test integration, not just compilation
✓ Add timeouts everywhere
✓ Document WHY, not just WHAT

Visible success hiding more profound problems. Post-deployment debugging is the real work.
