executed and there is another node available that satisfies the node affinity rule,
podA gets evicted from nodeA.
The `preferredDuringSchedulingIgnoredDuringExecution` type tells the scheduler
to respect node affinity when scheduling if that's possible. If not, the pod
gets scheduled anyway. It may happen that, over time, the state of the cluster
changes and now the pod can be scheduled on a node that actually fits its
preferred node affinity. When enabled, the strategy serves as a temporary
implementation of `preferredDuringSchedulingPreferredDuringExecution`, so the
pod will be evicted if it can be scheduled on a "better" node.

are evicted from nodes. Specifically, it tries to evict the minimum number of pods required to balance topology domains to within each constraint's `maxSkew`.
This strategy requires k8s version 1.18 at a minimum.
By default, this strategy only includes hard constraints, you can explicitly set `constraints` as shown below to include both:
```yaml
constraints:
- DoNotSchedule
- ScheduleAnyway
```
The `topologyBalanceNodeFit` arg is used when balancing topology domains while the Default Evictor's `nodeFit` is used in pre-eviction to determine if a pod can be evicted.
```yaml
topologyBalanceNodeFit: false
```
By default, this strategy only deals with hard constraints, setting parameter `includeSoftConstraints` to `true` will
include soft constraints.
Strategy parameter `labelSelector` is not utilized when balancing topology domains and is only applied during eviction to determine if the pod can be evicted.

--log-json-info-buffer-size quantity [Alpha] In JSON format with split output streams, the info messages can be buffered for a while to increase performance. The default value of zero bytes disables buffering. The size can be specified as number of bytes (512), multiples of 1000 (1K), multiples of 1024 (2Ki), or powers of those (3M, 4G, 5Mi, 6Gi).

--tls-sni-cert-key namedCertKey A pair of x509 certificate and private key file paths, optionally suffixed with a list of domain patterns which are fully qualified domain names, possibly with prefixed wildcard segments. The domain patterns also allow IP addresses, but IPs should only be used if the apiserver has visibility to the IP address requested by a client. If no domain patterns are provided, the names of the certificate are extracted. Non-wildcard matches trump over wildcard matches, explicit domain patterns trump over extracted names.
