This PR introduces several optional configurations aimed at improving the availability and resilience of HyperDX pods.
Additions:
• PodDisruptionBudget (disabled by default):
Ensures a minimum number of replicas remain available during voluntary disruptions. Defaults to a minimum of 1 replica but is configurable.
• Optional priorityClassName support:
Enables better control over pod scheduling and preemption by allowing assignment of a custom priority class.
• Optional resource requests and limits:
Defines resources for the app container to:
– Guarantee the pod receives the required CPU/memory.
– Prevent resource-hungry containers from affecting node stability.
• Optional topologySpreadConstraints:
Allows pods to be distributed across different nodes (using a specified topology key), reducing the impact of node-level failures.
All features are disabled or conservative by default to maintain backward compatibility and allow for gradual opt-in.
