Disclaimer: here you might not find something new if you know 12 factors app. The 12-factor app methodology 12factor.net, is a set of principles designed to enable applications to be built with portability and resilience when deployed to the web. These principles focus on declarative formats for automation, clean contracts with the operating system, and suitability for deployment on modern cloud platforms, thus minimizing divergence between development and production, enabling continuous deployment for maximum agility....

Reasons to upgrade to k8s 1.30 Container resource based autoscaling Container resource based autoscaling is now promoted to stable https://github.com/kubernetes/enhancements/issues/1610 Horizontal Pod Autoscaler examines the total resource usage of the entire pod i.e. sum of all containers and scale pods based on average CPU or memory usage. Container resource based autoscaling feature allows HPA to scale workloads based on the resource usage of individual containers within a pod, instead of the aggregated usage of all containers in the pod...

Kubernetes InPlacePodVerticalScaling feature Kubernetes v1.27 introduces InPlacePodVerticalScaling, allowing seamless pod resource resizing without restarts Enhanced Continuity: Eliminates the downtime and potential data loss caused by pod restart Cost Savings: Avoid overprovisioning and optimizing resource usage. InPlacePodVerticalScaling lets you allocate resources precisely as needed In this example for pod memory resources configuration, the resizePolicy indicates that changes to the memory allocation require a restart of the container, and for CPU resources the restart is not necessary during resizing....

After upgrading Kubernetes (k8s), you might encounter errors such as no matches for kind "Deployment" in version "apps/v1beta1". These errors typically indicate that certain resources have become deprecated. To resolve these issues without the need to delete your Helm chart, you can follow this simple solution: helm plugin install https://github.com/helm/helm-mapkubeapis helm mapkubeapis <releasename> helm upgrade <releasename> It’s important to note that you may still need to update your Helm chart templates, especially if there have been structural changes between versions....
