Chapter 4. Container Storage
While Kubernetes cut its teeth in the world of stateless workloads, running stateful services has become increasingly common. Even complex stateful workloads such as databases and message queues are finding their way to Kubernetes clusters. To support these workloads, Kubernetes needs to provide storage capabilities beyond ephemeral options. Namely, systems that can provide increased resilience and availability in the face of various events such as an application crashing or a workload being rescheduled to a different host.
In this chapter we are going to explore how our platform can offer storage services to applications. We’ll start by covering key concerns of application persistence and storage system expectations before moving on to address the storage primitives available in Kubernetes. As we get into more advanced storage needs, we will look to the Container Storage Interface (CSI), which enables our integration with various storage providers. Lastly, we’ll explore using a CSI plug-in to provide self-service storage to our applications.
Note
Storage is a vast subject in itself. Our intentions are to give you just enough detail to make informed decisions about the storage you may offer to workloads. If storage is not your background, we highly recommend going over these concepts with your infrastructure/storage team. Kubernetes does not negate the need for storage expertise in your organization!
