![]() Of course, when a Pod ceases to exist, the volume will cease to exist, too. Consequently, a volume outlives any Containers that run within the Pod, and data is preserved across Container restarts. Let me quote the definition of Volume here:Ī Kubernetes volume … has an explicit lifetime – the same as the Pod that encloses it. In order to differentiate Volume from Persistent Volume, people sometimes call it In-line Volume, or Ephemeral Volume. In the previous article, I mentioned that there is also a concept of Volume in Kubernetes. In this video recording, we dive into Kubernetes networking, and discuss best practices for a wide variety of deployment options. ![]() Take a deep dive into Best Practices in Kubernetes Networkingįrom overlay networking and SSL to ingress controllers and network security policies, we’ve seen many users get hung up on Kubernetes networking challenges. So when users request it, it can dynamically provision PVs with those predefined properties.īut those are not the only ways to use persistent storage in Kubernetes. In most cases, while being used with a Provisioner, it can be seen as the Provisioner with predefined properties. The PV in the same Storage Class can share some properties. Storage Class is a classification of PVs. It helps to remove the administrator from the critical path of creating a workload that needs persistent storage. Provisioner is a plugin used to provision PV for users. PV and PVC are always one to one mapping. When used with Storage Class, it will trigger the dynamic provisioning of a matching PV. ![]() ![]() Though after the introduction of Storage Class and Provisioner, users are able to dynamically provision PVs now. Originally PV was designed to be a piece of storage pre-allocated by administrator. Last time we talked about PV, PVC, Storage Class and Provisioner. ![]()
