I'm currently exploring Kubernetes and have set up a cluster in my homelab. Most of my single-instance services like NextCloud and Plex are deployed as Deployments with replicas set to 1, but I'm questioning whether I should be deploying them as standalone Pods instead. Is there a significant advantage to using Deployments over Pods for these types of services, or is either option acceptable?

Always opt for Deployments! Using a Deployment allows you to scale down to zero for maintenance without losing your configuration—if you delete a Pod, it’s gone and you'll have to recreate everything. Plus, with Deployments, you get features like rolling updates. Pods don’t support that.
Good to know, thanks!
