If you're using docker, then your project is already complex enough to migrate to k8s. You can install kubernetes on a single node, without any clustering, just to get its API and run your workloads there. It'll cost you 2GB of RAM. It won't be HA, but it'll be much more sane than docker. I'm saying it as a person who avoided k8s as much as I could, but in the end I loved it. Yes, it has some learning curve, but after that it's good.
