Almost 3 years ago, I paid for a few VPSs on which I host a variety of services. (Vaultwarden, gitea, drone, meshcentral, metabase, gptresearcher, etc)
Interspersed among the VPSs are a series of data processing containers to handle crypto data.
With the contract coming up for renewal, I’m exploring how to separate the hardware from the software so I’d only need to deploy the container to a pool of servers, and the infrastructure decides on which server to run the container, correctly route incoming requests, and update cloudflare dns for containers which are meant to be oublicly facing.
I went through the kubernetes the hard way tutorial and have a cursory understanding of kubernetes but with some substantial gaps which I couldn’t Google away.
For the replacement platform, I’m thinking to:
- Combine multiple VPSs as a baseline cluster to run internet-facing loads
- Use some home servers for backend/non-internet facing processes and make the data available on the Internet facing hosts.
- Add the ability to dynamically add more VPSs or preemptible instances from GCP/AWS
I’m still stuck on the first part. Standing up a kubernetes cluster using multiple VPS with different public IPV4 addresses.
Googling around heavily suggests this is not a common use case. Or at least I’m not using the correct terms.
Is there a better solution for me to pursue?
As another option why not docker swarm? I think it will do what you need and is much simpler than k8s.
I’ve been using caprover and really liking how simple and reliable it’s been. In the process of going from a single node to a swarm, still researching / experimenting but liking it so far!
I read into Docker Swarm, the community surrounding it is much smaller and there appear to be far fewer tutorials compared with k8s.
In addition to hosting the usual self-hosted applications that are often mentioned, I also do a good amount of processing of crypto and other financial data. Being able to more dynamically add/remove servers and have the containers automatically assigned / routed should at least in theory save me a lot of time administering the infrastructure.
