![]() ![]() It comes with its own data lifecycle which is separate from the lifecycle of Kubernetes pods. This is a storage element defined by an administrator. In order to enable persistent storage (storage that is not deleted on a container/pod removal), Kubernetes has a couple of key concepts. A volume can aid in all kinds of storage such as network file systems (NFS), local storage devices, and cloud-based storage services. VolumesĪs the fundamental storage component, Volumes play a significant role in the world of Kubernetes, helping provide storage to containers. These storage options can be setup in-house or purchased separately from cloud providers or data service providers. Kubernetes also has several kinds of persistent storage such as file, block, or object storage options. Non-persistent data is stored in a temporary storage volume and once the container or pod is shut down, the data is deleted. This is handy, convenient, and manageable but not sturdy. Ephemeral storage utilizes a temporary directory on the device that is hosting the Kubernetes pod. Every container comes with ephemeral storage by default. The most basic one is non-persistent or also called ephemeral storage. There are different types of storage in Kubernetes. Key concepts of Kubernetes storage Source: In this scenario, containerization supports packaged software delivery to cater to these needs, allowing applications to be released more frequently without experiencing any downtime. Also, developers are looking to increase deployment velocity to where they can ship code multiple times a day. Web services are getting modernized and the availability of applications 24/7 is what users expect. If Kubernetes storage options are managed well you can greatly eliminate or minimize administrative overhead and can improve the performance of applications that perform data-intensive tasks. This helps in the creation of dynamic storage resources that can further cater to multiple types of applications. The reason is that Kubernetes handles persistent and non-persistent data in a cluster in different ways. When you manage containerized applications, Kubernetes storage could prove immensely beneficial. It enables Devops teams to proficiently deploy, operate, and scale containers in a cloud or on-prem environment. Kubernetes is the leading container orchestration solution today. You’ll get an understanding of the key concepts related to Kubernetes storage and be able to assess how your organization can better manage Kubernetes storage. In this article, let us decode all about one aspect of Kubernetes – storage. As with all budding technologies, there is a lot of curiosity and even some ambiguity around it. The trend of containerizing applications and managing them with an orchestrator like Kubernetes is still new. ![]()
