Kubernetes Storage Plugins

These Kubernetes Storage plugins lay the foundation for the easy management and internal operations of storage solutions in containers. It does the configurational settings on containers that are orchestrated by Kubernetes. These plugins increase the platform’s adaptability and guarantee a customized solution for a range of storage requirements. The following 2 popular kubernetes storage plugins

2. Container Storage Interface ( CSI )

Network File System Plugin

  • Effortless Data Sharing: NFS plugin servers a vital, in establishing the connection between Kubernetes volumes and network file systems without any difficulties for transmission of data.
  • Cluster-wide Accessibility: The NFS plugin helps with enabling stable data transmission among the clusters improving the efficiency of resource usage.
  • Scalable Solutions: NFS acts as a great option for customizing storage needs facilitating effective data exchange and offering scalable solutions.

Container Storage Interface, or CSI

  • Standardized Integration: Container Storage Interface ( CSI ) comes with a standardized Interface with common language storage providers facilitating effortless integration with Kubernetes.
  • Flexibility And choice: The CSI plugin provides a method for the users to select the storage options that exactly meet to the needs of their applications.
  • Interoperability: CSI comes with adopting a standardized approach for enhancing the interoperability providing a smooth and efficient storage experience with containerized settings.

Kubernetes – Volumes

Kubernetes is an open-source container orchestration tool developed by Google. It is primarily employed to automate the deployment, scaling, and management of software. In short, Kubernetes is termed as K8s. Kubernetes is currently maintained by the Cloud Native Computing Foundation. Although it now supports both containerd and CRI-O in addition to the Docker runtime Engine with which it was first intended to communicate. Automating the operations of container management is Kubernetes’ primary goal. It has built-in commands for application deployment and rolling out necessary modifications to the application. Companies like Google, Spotify, and Capital One are now using it.

What are known as Volumes?

On-disk files present in a container are ephemeral storages, they present some or other problems for non-trivial applications while running in containers. One of the major problems is the loss of files when the container crashes. The container is restarted by kubelet but it is restored in a clean state without any data. Another problem occurs when we are sharing files between containers that are running together in a Pod. All these problems are solved by Kubernetes volume abstraction....

Volumes in Kubernetes

Although Docker has the concept of Volumes it is loose and not well managed. Generally, a docker volume is a directory on a disk that is present inside another container. Though Volume drives are provided by docker functionality is very limited. Kubernetes supports multiple types of Volumes. Any number of volumes can be used by a Pod simultaneously. Persistent volumes are present beyond the lifetime of a pod even after they are destroyed but Ephemeral volume types have a lifetime of a pod which means they are destroyed once the lifetime of the Pod is finished. For any kind of Volume in a pod, data is preserved across container restarts....

Conclusion

In this evolving era of Container Orchestration, Kubernetes plays an essential role in the management of data with persistence. It offers flexible management of data within pods ranging from permanence to short-term duration of storing data with volume types such as EmptyDir Volumes for temporary storage easy to use and Hostpath volumes making data permanent in the host filesystem. Kubernetes comes up with many features for orchestrating the containers effectively in an automated way with services such as “ConfigMap” resource for streamlining the configuration management, and hostPath Volumes for giving storage flexibility with the hostPath file system improving the overall efficiency of container applications....
