I think etcd is basically a k8s only project now- Consul has a ton of quality of life stuff added on.

There's always Zookeeper.

Anything but Zookeeper! It was written long before the cloud was a thing, relies on hard-coded IPs, and is practically impossible to operate idiomatically in a cloud environment (unless you’re using statefulsets in K8S to paper over it). It has served us well over the past two decades, but it’s nigh time to give it the proper burial ceremony it deserves.

ZK in statefulsets can still get wedged super hard, especially if you power cycle all the nodes. It's pretty unpleasant.

I hate etcd with the best of them, but etcd is used in a lot more places than just kubernetes:

https://github.com/apache/apisix/blob/master/docs/en/latest/...

https://github.com/traefik/traefik#:~:text=Etcd,

https://github.com/zalando/patroni#patroni-a-template-for-po...

https://github.com/purpleidea/mgmt/tree/0.0.26/etcd (this one shows up on HN quite a bit)

https://github.com/sorintlab/stolon#features

It's actually one of the major reasons I wouldn't touch those projects
