In this tutorial, we will walk through the setup of a single-node K3s Kubernetes cluster with Rancher, together with the S3 Gateway (s3gw) and a Longhorn PV (Persistent Volume). This guide will use Digital Ocean, but these instructions will likely work with other cloud providers as well.
s3gw is an S3-compatible service focused on deployments in a Kubernetes environment backed by any PVC, including Longhorn. Since its inception, the primary focus has been on cloud native deployments. However, the s3gw can be deployed in a myriad of scenarios, provided some form of storage is attached.
Increased demand for cloud storage solutions has become a crucial topic in recent years: companies are requiring data to be made more readily available for their cloud-native applications.
