🚫 Kubernetes Anti-Patterns You Should Avoid! 🚫

Kubernetes is a powerful tool that helps us orchestrate and manage containerized applications, but like any technology, there are pitfalls we must navigate carefully. Here are some common Kubernetes anti-patterns that can turn your K8s experience from a dream into a nightmare! 💭

💥 1. Monolithic Deployments in K8s
Deploying a monolithic application on Kubernetes is like buying a Ferrari for grocery shopping. 🏎️ Kubernetes shines with microservices, where independent components scale and recover seamlessly. Avoid turning it into a VM replacement by deploying monoliths without any optimization!

💥 2. Hardcoding Configurations
Hardcoding secrets, environment variables, or configurations within containers? That's a no-go! 🔒 Use ConfigMaps and Secrets to manage configurations and sensitive data securely. It’s 2024; let’s keep our secrets safe!

💥 3. Ignoring Resource Requests and Limits
Not setting resource requests and limits is like sailing without an anchor ⚓—you’ll either underutilize your resources or crash your nodes. Define these properly to ensure stability, fairness, and efficiency.

💥 4. Overusing Privileged Containers
Running containers as root or with elevated privileges exposes your cluster to potential security breaches. 🚨 Practice the principle of least privilege and use Role-Based Access Control (RBAC) for fine-grained security.

💥 5. Treating Kubernetes as ‘Set and Forget’
Kubernetes needs continuous monitoring, updates, and optimization. 🕵️‍♂️ Be proactive! Use tools like Prometheus, Grafana, and Jaeger to monitor performance, logs, and traces. Kubernetes is a living, breathing ecosystem—keep it healthy!

💥 6. Not Using Liveness and Readiness Probes
Deploying applications without liveness or readiness probes is like flying blind. ✈️ These probes help K8s understand the state of your applications, ensuring automatic restarts and smooth rollouts.

🔍 The Bottom Line: Kubernetes is not just a tool—it’s a mindset. Understand the dos and don’ts to leverage its full power.
