## Why people recommend it

- Runs well on a single node (5 comments in the sample): "it feels like a real cluster but it's all on a single piece of hardware which makes snapshots etc super simple" ([source](https://news.ycombinator.com/item?id=48996844)) "I think single node kubernetes is very underrated, both for running a single project or for multiple." ([source](https://news.ycombinator.com/item?id=48997485)) "Absolutely recommend k3s. Start with a single node and keep on scaling as customer base increases." ([source](https://news.ycombinator.com/item?id=45823268))
- Quick, simple install and setup (5 comments in the sample): "K3S takes about 5 minutes to setup the first time and you instantly have an entire universe of standardized operational tooling." ([source](https://news.ycombinator.com/item?id=48665489)) "You can bootstrap k3s with "curl -sfL https://get.k3s.io | sh -". If you need to do that over ssh it works just fine." ([source](https://news.ycombinator.com/item?id=48004756)) "You drop a single binary onto the node, run it, and you have a fully functional one-node k8s cluster." ([source](https://news.ycombinator.com/item?id=46396796))
- Access to Kubernetes ecosystem (3 comments in the sample): "a single, unified, standardized, extensible control plane that lots of software already supports" ([source](https://news.ycombinator.com/item?id=47876751)) "just use k3s or k0s and you will still benefit from the absolutely massive ecosystem" ([source](https://news.ycombinator.com/item?id=46581855)) "k3s is a good non overkill alternative while benefiting from everything k8s offers." ([source](https://news.ycombinator.com/item?id=46476675))

## What people warn about

- Adds operational complexity (2 comments in the sample): "There is lot of operation complexity in general and most of us can do without." ([source](https://news.ycombinator.com/item?id=48004526)) "It also breaks a lot and does add a whole bunch of complexity" ([source](https://news.ycombinator.com/item?id=50110762))
- Manual upkeep and troubleshooting (2 comments in the sample): "I do remember having to touch the K3s YAML directly, and maybe having issues also persisting it" ([source](https://news.ycombinator.com/item?id=45972820)) "resetting k3s in NixOS is not that straightforward and requires manual input" ([source](https://news.ycombinator.com/item?id=45972504))
- Curl-to-shell install concerns (2 comments in the sample): "Not a fan of their curl -sfL https://get.k3s.io | sh - installation method" ([source](https://news.ycombinator.com/item?id=47039401)) "dodgy curl piped to bash scripts that users install without question" ([source](https://news.ycombinator.com/item?id=49015142))
