Summary

In the final installment of the Kubernetes Anti-patterns series, several critical missteps in deploying and managing applications on Kubernetes are highlighted. Misusing health probes is a common issue where developers fail to correctly configure readiness and liveness probes, potentially causing cascading failures. Helm is emphasized as the essential package manager for Kubernetes, offering more comprehensive management than simple templating solutions by tracking application resources post-deployment and facilitating easy rollbacks. The importance of deployment metrics is underscored, as they provide crucial insights into application health and performance, which should be integrated into the deployment process rather than being reviewed manually. A robust strategy for managing secrets is vital, ensuring that only necessary secrets are accessible to applications during runtime, while build secrets remain separate and secure. Finally, the text advises against attempting to use Kubernetes as a one-size-fits-all solution, recommending its initial use for stateless services to leverage its scalability and elasticity, while suggesting that stateful services might be better kept outside the cluster during the early stages of migration.
