# NAME
|
||
|
|
kube-scheduler \- Schedules containers on hosts.
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
**kube-scheduler** [OPTIONS]
|
||
|
|
|
||
|
|
# DESCRIPTION
|
||
|
|
|
||
|
|
The **kubernetes** scheduler is a policy-rich, topology-aware, workload-specific function that significantly impacts availability, performance, and capacity. The scheduler needs to take into account individual and collective resource requirements, quality of service requirements, hardware/software/policy constraints, affinity and anti-affinity specifications, data locality, inter-workload interference, deadlines, and so on. Workload-specific requirements will be exposed through the API as necessary.
|
||
|
|
|
||
|
|
The kube-scheduler can take several options.
|
||
|
|
|
||
|
|
