I have 2 node-pools(pool1-regular,pool2-preemtible) in my cluster. one node pool is preemtible and the other is regular. beacuse i cant really trust preemtible machine i want deploy my app so that at least one of my pods is in pool1-regular. i managed to set the affinity so no pod with the same name will be scheduled to the same node. but i dont now how to create some hybrid solution
Here's a link to my deployment.yaml
any ideas?
The most direct solution is to create 2 deployments, one that uses the preemtible nodes and another that uses non preemtible. Both deoyments will have basically the same tags so you can have a single service exposing both.
Deployment A will include a host=preemptible and will use an affinity to schedule on preemtible nodes. Deployment B will do the same but with a non-preemptible label.
