Why your orchestration sucks...

- The code for deploying your app , being as complicated as it is, implies that your app itself is too complicated.
- Your APIs arent probably versioned properly.
- You have distributed the need for persistent state across containers in a way that fails to minimize storage coupling.

Fix this stuff in  your dang app, then after your app doesn't suck, tell me how bad you need 'technology X' as your deployment tooling.  Chances are, it wont matter much , or at least not as much, anymore. 

Good code is good code and no amount of k8s in the world can get around the fact that broken apps remain broken, even in the cloud.
