Especially for databases fast read and write is required. Offloading the workload to a NAS most of the time is slower. The solution I use is to provision on-node storage with <a href="https://longhorn.io/">Longhorn</a>. Longhorn acts as a CSI and offers on-node storage, replication, backups and more.</p> <p>As I am currently building a Talos cluster I need to integrate the longhorn CSI into the setup. This is not as straigt forward as with K3s oder K8s, as Talos has tighter security constraints and also needs additional plugins to handle SCSI - the underlying file system protocol used by longhorn. On top I am using <a href="https://budimanjojo.github.io/talhelper/latest/">Talhelper</a> to allow a GitOps style usage of talosctl. The main advantage is the encryption of secrets used by talos config files with <a href="https://github.com/getsops/sops">SOPS</a> - something that I already use for Tofu and fluxCD.</p>
