Set Up Time Check Pod in Kubernetes

☸️ Day 10: Set Up Time Check Pod in Kubernetes | Kubernetes Series

Welcome to Day 10 of the Kubernetes Series! In this lab, you’ll learn how to configure Kubernetes Pods with ConfigMaps, environment variables, and persistent logging using mounted volumes.

📌 Lab Objective:
Create a BusyBox-based Pod in a custom namespace that periodically logs the system time into a file using configuration values stored in a ConfigMap.

🛠️ Task Requirements:

Namespace: xfusion
Pod Name: time-check
Container Name: time-check
Container Image: busybox

ConfigMap:
Name: time-config
Data:
TIME_FREQ=6

Command:
while true; do date; sleep $TIME_FREQ;done

Log File Location:
/opt/security/time/time-check.log

Volume Name:
log-volume

Mount Path:
/opt/security/time

💻 What You’ll Configure & Verify:

🔹 Create Kubernetes namespaces
🔹 Create and manage ConfigMaps
🔹 Inject environment variables from ConfigMaps
🔹 Configure BusyBox containers
🔹 Execute custom shell commands in Pods
🔹 Create and mount volumes inside containers
🔹 Store application logs persistently
🔹 Verify time logging functionality

📚 What You’ll Learn:

Kubernetes ConfigMaps
Environment Variables in Pods
Volume Mounts
BusyBox Containers
Custom Container Commands
Namespace Management
Pod Logging Techniques
kubectl Pod Configuration

🌟 Why This Lab Matters:
Real-world Kubernetes applications frequently use ConfigMaps and mounted volumes for configuration management, logging, and dynamic runtime behavior. Understanding these concepts is essential for managing production-grade workloads.

🎯 Series: Kubernetes Series
