Say I have a node.js or other single-process app that doesn’t support multiple threads, but could benefit from spinning up multiple stateless instances. Does Rancher with Cattle allow this?
Whenever I try scaling up a service, it stays degraded and I get errors about constraints not being met. I guess it’s trying to spin the instance up on multiple hosts, but in this case I only have one and am using Rancher mainly for the tooling and easier administration. Is there no way to, say, spin up multiple instances of the app on the same multi-core server?
