OpenShift bilan ish tajribangiz qanday?

OpenShift Container Platform bilan ishlash bo'yicha tajribam bor, jumladan:

• Klasterlarni joylashtirish va boshqarish: On-premise va bulutda (AWS, Azure) klasterlarni o'rnatish. Tarmoq infratuzilmasi, saqlash va xavfsizlikni sozlash.
• Ilovalarni ishlab chiqish va joylashtirish: Dockerfile yaratish, tasvirlarni qurish, OpenShift shablonlari va Kubernetes manifestlarini yozish. CI/CD pipeline'laridan (Jenkins, GitLab CI) foydalanish.
• Boshqaruv va monitoring: Foydalanuvchilar, loyihalar, kvotalarni boshqarish. Klaster va ilovalar holatini monitoring qilish uchun Prometheus va Grafana'dan foydalanish. Ogohlantirishlarni sozlash.
• Muammolarni hal qilish: Podlar, xizmatlar, marshrutlar bilan bog'liq muammolarni tashxis qilish. Loglar va voqealarni tahlil qilish.
• Ekosistema komponentlari bilan ishlash: OpenShift Registry, OpenShift Routes, OpenShift Service Mesh (Istio), OpenShift Pipelines (Tekton).

Vazifa misollari:

• Monolitik ilovani konteynerlarga o'tkazish va OpenShiftda joylashtirish.
• Avtomatik test qilish, qurish va mikroxizmatlarni OpenShiftga joylashtirish uchun CI/CD pipeline'ini yaratish.
• Ma'lumotlarni replikatsiya qilish va avtomatik o'tkazish bilan bardoshli OpenShift klasterini sozlash.
• Klasterdagi barcha ilovalar uchun markazlashtirilgan loglash va monitoringni joriy etish.

Ikkala komand satri (oc) va OpenShift veb konsolidan foydalanaman. OpenShift asoslangan Kubernetes tushunchalarini yaxshi tushunaman (pods, replicaset, deploymentlar, xizmatlar).
