Are you interested in Kubernetes and want to learn more about its management? If that is the case, then you are in the right place. With this article on Kubernetes management, you will be able to discover a lot of important things that will allow you to make the most out of your Kubernetes experience.
So without further ado, let’s get started.
Clusters are the foundation of GKE – the Kubernetes objects which symbolize your containerized apps all run top of a certain cluster. Keep on reading this article on Kubernetes management to know more how to manage clusters.
- Update Clusters
The present condition of a cluster upgrade is usually provider dependent. For instance, if you choose kublr.com as your Kubernetes platform, it will manage and upgrade your clusters securely and reliably.
Further, it is highly recommended that the admins should consult the version-specific upgrade notes and release notes before updating to ensure that everything is going to be fine.
When it comes to updating AKS (Azure Kubernetes Service) cluster, the AKS will allow simple self-service upgrades of the nodes and the control plane in your clusters. Nevertheless, the entire process is described in the AKS documentation of Azure.
- Resize Clusters
If you are running short on sources you can simply add more machine into it most especially if your cluster is currently in Node self-registration mode.
On the other hand, if you are utilizing the Google Kubernetes Engine (GCE) it is usually performed by resizing the Instance Group that manages your Nodes.
To resize clusters simply follow the commands below:
- Press on Compute, then Compute Engine, followed by Instance Groups. After that look for your own group and edit it.
Control Plane Management
Control plane refers to the collection of processes that will coordinate and at the same time manage the state of the clusters, categorized by responsibilities. What’s more, this will also make scheduling decisions to help the cloud workflows and applications the worker nodes run.
This is a distributed and lightweight cluster manager that reliably and persistently keeps the configuration data of the cluster. This component of the control plane also offers an accurate and consistent representation of the clusters at any given time.
- Control manager
This will communicate with the API servers in order to delete, create, and update managed resources.
With the Scheduler, you will be able to track the resource usage of every node guaranteeing that the allotted workload will not exceed what is accessible on the virtual or physical machine.
- API Server
This component will serve the Kubernetes API with JSON over HTTP. API servers, on the other hand, will offer both external and internal interface to Kubernetes. In addition to that, it will process and validate restful requests as well as permits communication across and between libraries and tools.
Aside from the above-mentioned, there are other Kubernetes management details that you need to know. But hopefully, you still find this article on Kubernetes management useful even though the provided info is limited.
