The Complexity of a Growing API As your cluster grows, the number of supported API resources increases. You have to manage Ingresses, ServiceAccounts, NetworkPolicies, and custom resources. If you need to write a configuration file for a resource you’ve never…
The Drift Risk of Step-by-Step Instructions When managing servers, you typically write scripts that dictate the exact steps to install packages, start services, and edit configurations. This is imperative management. While simple, it presents challenges at scale. If a step…
The Limitations of Raw NodePorts in Cloud Environments If you deploy your applications in a public cloud environment (such as AWS, GCP, or Azure) and expose them using NodePort services on high-range ports like 30008, you run into production limitations.…
The Security and Resource Risks of a Flat Cluster If you run different environments (like Development, Testing, and Production) on a single cluster without boundaries, you face operational risks. For instance, developers might choose conflicting resource names, preventing workloads from…
Tracking Ephemeral Pod IPs Internally In a multi-tier application architecture, internal service discovery is a primary concern. The frontend web server needs to talk to the backend API, and the API needs to query the database. However, pods are temporary.…
The Isolated Overlay Network Every pod in your CNI network receives an IP address. However, these IPs are assigned from a private overlay network managed by the Container Network Interface (CNI). While pods can communicate with each other using these…
The Downtime Risks of Manual Upgrades Suppose you have a running ReplicaSet managing three instances of your application at version 1.0. Your development team releases version 2.0. If you only use a standard ReplicaSet, updating the application is a manual…
The Outage Risk of Standalone Pods If you run an application on a single pod, you are exposed to downtime. The host VM running that pod could run out of memory or crash. When this happens, your pod goes offline…
The Friction of Command-Line Infrastructure When starting out with containers, you often configure everything using CLI flags. You run commands like: docker run -d –name my-app -p 80:80 -v /var/data:/data –restart=always my-image:v2 While this is quick for local testing, it…
The Isolation Friction of Multi-Container Apps If you are used to working with standalone containers, you treat a single container as your basic unit of deployment. You run a container for your app, and you scale it by spinning up…
