Kubernetes Tips! 15 kubernetes tips and tricks every Kubernetes Admin should be aware of 👇⚓️
1/ 🔍 Namespace Mastery: Keep your clusters organized by using namespaces effectively. Group resources logically, isolate environments, and simplify management. #K8sTips #Kubernetes
2/ 🚦 Resource Quotas & Limits: Set resource quotas to prevent resource hogging. Use limits to ensure fair sharing and avoid one misbehaving pod impacting others. #K8sTips #Kubernetes
3/ 🔄 Rolling Updates FTW: Use rolling updates for deployments. This ensures minimal downtime by gradually replacing instances, making updates smoother and user-friendly. #K8sTips #Kubernetes
4/ 🛡️ RBAC Best Practices: Fine-tune access control with Role-Based Access Control (RBAC). Grant least privilege, regularly audit roles, and secure your cluster. #K8sTips #Kubernetes
5/ 📚 Documentation Matters: Kubernetes has extensive documentation. Embrace it! Understanding features deeply will save you time and prevent headaches. #K8sTips #Kubernetes
6/ 💻 Imperative vs. Declarative: Know when to use imperative commands (kubectl run) vs. declarative YAML files. Declarative config is more maintainable and scalable. #K8sTips #Kubernetes
7/ 🔄 Pod Disruption Budgets: Implement PodDisruptionBudgets to control disruptions during voluntary disruptions like upgrades or maintenance. Keep things stable! #K8sTips #Kubernetes
8/ 🚨 Monitoring & Alerts: Set up robust monitoring and alerting. Prometheus and Grafana are your friends. Early detection prevents disasters. #K8sTips #Kubernetes
9/ 🛠️ Helm Charts Wisdom: Leverage Helm charts for packaging, versioning, and managing Kubernetes applications. It simplifies complex deployments. #K8sTips #Kubernetes
10/ 🔄 CronJobs for Scheduled Tasks: Use CronJobs to automate recurring tasks within your cluster. Scheduled maintenance, backups, and cleanup made easy! #K8sTips #Kubernetes
11/ 🧹 Resource Cleanup: Regularly audit and clean up unused resources. Avoid resource sprawl and keep your cluster efficient. #K8sTips #Kubernetes
12/ 🚀 Custom Resource Definitions (CRDs): Extend Kubernetes API with your own resources. CRDs enable you to define custom objects and controllers for specialized use cases. #K8sTips #Kubernetes
13/ 🔗 Network Policies: Define network policies to control the communication between pods. Enhance security and limit potential attack surfaces. #K8sTips #Kubernetes
14/ 🔄 Horizontal Pod Autoscaling: Enable autoscaling for your deployments. Let Kubernetes automatically adjust the number of pods based on resource usage or custom metrics. #K8sTips #Kubernetes
15/ 🚛 Persistent Volumes: Understand and leverage Persistent Volumes and Persistent Volume Claims. Ensure data persistence and manage storage effectively. #K8sTips #Kubernetes
16/ 🤖 Pod Security Policies (PSPs): Tighten security by using Pod Security Policies. Control what actions pods can perform, reducing the risk of malicious activities. #K8sTips #Kubernetes
17/ 📤 kubectl Output Formats: Master kubectl by customizing output formats. Use json, yaml, or even custom-columns for a cleaner, more readable view of your cluster state. #K8sTips #Kubernetes
18/ 🚦 Liveness & Readiness Probes: Set up effective liveness and readiness probes for your containers. Ensure your applications are healthy and ready to handle traffic. #K8sTips #Kubernetes
19/ 🔄 StatefulSets for Stateful Workloads: When dealing with stateful applications, use StatefulSets for stable, unique network identifiers and persistent storage. #K8sTips #Kubernetes
20/ 🧭 Kubeconfig Management: Manage multiple clusters effortlessly with kubeconfig files. Use contexts and switch between clusters seamlessly, saving time and reducing errors. #K8sTips #Kubernetes
