This article will explain in detail whether the Photon volume plug-in is supported in the new features of kubernetes1.5. The content of the article is of high quality, so the editor will share it with you for reference. I hope you will have some understanding of the relevant knowledge after reading this article.

The role of volumes in Kubernetes is to provide persistent storage to POD, which can be mounted to containers in POD, which in turn provides persistent storage to containers.

You can see from the figure that the attribute of the structure PodSpec is Volumes, through which the Volumes attribute can be associated with the structure Volume and the structure VolumeSource, and the Volumes attribute is an array type, which means that the POD can be associated with multiple different types of volumes.

The structure Container represents the container in POD. This structure has an attribute VolumeMounts, which lets the container know the specific storage path to be mounted. This VolumeMounts attribute is also an array type, that is, the container can mount multiple storage paths.

Support for new volume plug-ins

Kubernetes supports a total of 23 volume plug-ins. A new volume plug-in PhotonPersistentDisk has been added to Kubernetes1.5.

Photon

Photon, VMware's own version of Linux, is a lightweight Linux used to build Container hosts and optimized for vSphere, which can improve the performance of a large number of Container in vSphere environments. Photon supports a number of Container technologies, including RocketContainer (rkt) and Pivotal Garden Container images in addition to popular Docker. When Photon is deployed in VMware virtualization platform products such as vSphere, it can improve performance by removing the repeated core cache mechanism between Linux core and vSphere Hypervisor, and can also use the network micropartition (Micro-Segmentation) technology of VMware NSX network virtualization to enhance security services. VMware has been validated to be deployed on vSphere 5.5,6.0,6.0,vCloud Air, VMware Fusion and VMware Workstation products to help enterprises seamlessly migrate applications on Fusion, VMware Workstaion and other test environments to formal environments using vSphere.

Summary

Kubernetes1.5 supports a total of 23 volume plug-ins. From these volume plug-ins, we can see that there are more and more Kubernetes community participating manufacturers. These 23 volume plug-ins can cover GoogleCompute Engine public cloud, Amazon WebService public cloud, Microsoft Azure public cloud, OpenStack-based public cloud, and VMware vSphere-based private cloud. With the addition of vmware's Photon persistent volume support in the Kubernetes1.5 version, we can see that the influence of Kubernetes is expanding. In the future, there will be more vendors to provide support for Kubernetes.

As can be seen from so many clock volume plug-ins, Kubernetes1.3 began to launch a cross-cloud Kubernetes cluster management feature: "Cluster Alliance", which means that Kubernetes will use public cloud IaaS resources around the world to become a super cluster management tool that can span different public cloud IaaS resources to achieve rapid deployment and management of applications around the world.

On the new features of kubernetes1.5 whether to support the Photon volume plug-in to share here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
