alt Hacker NewsFair points, and yes, failed deploys need to be handled explicitly.
In our case, the answer is not "hope and bash". We deploy versioned images, use health checks, monitor the result, and keep rollback simple: redeploy the previous known-good image/config. Host upgrades are also treated as maintenance events, with backups and a recovery path, not as something Compose magically solves.
But I think there is an opposite mistake too: assuming every production system should be operated like a high-scale tech company.
Many production workloads are boring, predictable, and business-critical. They do not need aggressive autoscaling, multi-node orchestration, or constant traffic-spike handling. They need reliable deploys, backups, monitoring, health checks, and a clear rollback path.
That is where Compose can be a good fit: simple operational model, understood failure modes, low moving parts.
Kubernetes becomes much more compelling when you actually need automated failover, rolling deploys, autoscaling, multi-node scheduling, and stronger deployment primitives.
Not needing Kubernetes is not necessarily denial, it is just choosing the complexity budget that matches the problem.
Definitely not a one-size-fits-all choice, but Kubernetes can be so easy and there are so many benefits that get you from one small app to a medium sized business that it seems like a no-brainer for someone starting out. Spinning up k3s is pretty minimal overhead, but right away you can handle storage and backups very easily, automatic certs for all your apps with cert-manager is pretty much a one-and-done, traffic management for external and internal tools is easy, and even logins for websites is just an annotation in a yaml file. You can spin up and try out any software you want without spending time configuring it or setting up additional servers- and when you do need more hardware, it's one command on a virtual server, and just about as easy with physical hardware.
2-3 miniPCs, cloudflare, tailscale, and k3s can save (possibly tens of) thousands on SaaS products, and would probably scale you to a company of dozens AND host your product.
