[Docker-Homelab Ep5] - Docker CrashLoopBackOff Explained: Debugging a Restarting Container

Описание: Updated for Docker & DevOps in 2025 — Why does your container keep crashing and restarting?

In this hands-on Docker lab, we’ll simulate a real CrashLoopBackOff error by breaking a Flask app on purpose. The container keeps restarting, and we’ll use Docker commands to debug and fix it.

🔹 What you’ll learn in this video:

What CrashLoopBackOff means in Docker & Kubernetes

Why missing environment variables or bad configs crash containers

How to debug with docker logs, docker ps, and docker exec

Fixing the issue step by step like in a real production scenario

✅ By the end, you’ll know exactly how to handle containers stuck in a crash loop — a critical skill for every DevOps engineer.
