What else is out there? I'm running docker swarm and it's extremely hard to make it work with ipv6. I'm running my software on a 1GB RAM cloud instance and I pay 4EUR/month, and k8s requires at least 1GB of RAM.

As of now, it seems like my only alternative is to run k8s on a 2GB of RAM system, so I'm considering moving to Hetzner just to run k3s or k0s.

Are you not using docker swarm behind a reverse proxy?

ie nginx has the public facing ipv4 & ipv6 address(es), with docker swarm behind that communicating to the nginx proxies over ipv4

I have traefik as part of the docker-compose file. Installing nginx on the host seems less reproducible, though it could fix my problem. I guess I would choose something as caddy (I'm not that happy with traefik)

I've not used Caddy before personally, but if it does reverse proxying then it'd probably work fine rather than Nginx. :)

I run k3s on a single hetzner ARM64 VPS and it works pretty well for personal projects. 2 vcpu and 4GB ram for 4€/mo.
