As the most popular container orchestration system, Kubernetes is now the new norm for leading enterprise. However, it is a notoriously complex system to leverage and maintain. That’s why getting a good grasp of what to do and what to avoid, and understanding what is possible will get your Kubernetes deployment off to a solid start.
You don’t have to stress yourself for this happen since learning from experts can help do the trick. These common recommendations cover common issues touching on Kubernetes deployment, and how to navigate through them.
Use Namespaces
Namespaces in Kubernetes are vital to utilize in order to organize your objects, security reasons, and create a logical partition within your cluster. The three namespaces in a K8s cluster, include default, Kube-public, and Kube-system. You can count on RBAC to control access to particular namespaces to limit the access of a group to control the blast-radius of any issues that might occur.
Leverage Autoscaling
Where possible, you can employ autoscaling to dynamically fine-tune the number of pods (horizontal pod autoscaler), the amount of resources consumed by the pods (vertical autoscaler), or the number of nodes in the cluster, based on the demand for resources. But leveraging autoscaling also brings with it a host of challenges.
One such challenge is failing to store persistent data in the container’s local filesystem, as it would prevent horizontal autoscaling. To get the most from cluster autoscaler, you should consider using it when highly variable workloads exist on the cluster that may require different amount of resources at different times, depending on demand.
Use Multiple Nodes
Kubernetes deployment on a single node is never a good idea if you want to build in fault tolerance. In this case, you’re better off employing multiple nodes in your cluster so that workloads can be spread between them.
Following the best practices listed in this simple guide when designing, running, and maintaining your Kubernetes cluster will certainly put you on the path to succeed on your modern application journey. That’s what you need to achieve your business goals with ease.
