Kubernetes ConfigMaps Tutorial | Inject Environment Variables & Config Files In this video, I walks you through Kubernetes ConfigMaps, one of the most practical ways to manage configuration in kubernetes clusters. Instead of hardcoding configuration into your container images, ConfigMaps allow you to inject environment variables or mount configuration files at runtime, making your applications more flexible, maintainable, and cloud-native. By the end of this tutorial, you will learn how to: - Create ConfigMaps using literals - Use ConfigMaps in pod manifest files - Inject ConfigMaps as volumes into your pods - Update ConfigMaps without rebuilding containers - Apply ConfigMaps in real-world scenarios like Nginx or Apache 🔗 Configuring Apps in Kubernetes with Commands, Args & Environment Variables - ▬▬▬▬▬▬▬ Timestamps ⏰ ▬▬▬▬▬▬▬ 00:00 - Introduction 00:32 - Creating ConfigMaps using literals 02:17 - Using ConfigMaps in pod manifest file 05:41 - Injecting ConfigMaps as a volume in the pod 09:43 - Restarting containers after updating ConfigMaps 11:45 - Conclusion For 1:1 mentorship, consultations, or career guidance, you can book a session with me here: 🔗 Watch Related Playlists: - Kubernetes: - Github Actions: - Ansible: - AWX: - AI: ▬▬▬▬▬▬ Connect with me 👋 ▬▬▬▬▬▬ LinkedIn: Website: Medium: @kumarnikhil811 #kubernetes #containers #cncf #nginx #apache
