version: kubernetes 1.6.2

##kube-scheduler Configuration

下面是我梳理的kube-scheduler的完成配置：

flag	default value	comments
--address string	0.0.0.0	The IP address to serve on (set to 0.0.0.0 for all interfaces) (default "0.0.0.0")
--algorithm-provider string	DefaultProvider	The scheduling algorithm provider to use, one of: DefaultProvider
--failure-domains string	kubernetes.io/hostname, failure-domain.beta.kubernetes.io/zone, failure-domain.beta.kubernetes.io/region	Indicate the "all topologies" set for an empty topologyKey when it's used for PreferredDuringScheduling pod anti-affinity. (default "kubernetes.io/hostname,failure-domain.beta.kubernetes.io/zone,failure-domain.beta.kubernetes.io/region")
--feature-gates value		A set of key=value pairs that describe feature gates for alpha/experimental features. Options are: AllAlpha=true
--google-json-key string		The Google Cloud Platform Service Account JSON Key to use for authentication.
--hard-pod-affinity-symmetric-weight int	1	RequiredDuringScheduling affinity is not symmetric, but there is an implicit PreferredDuringScheduling affinity rule corresponding to every RequiredDuringScheduling affinity rule. --hard-pod-affinity-symmetric-weight represents the weight of implicit PreferredDuringScheduling affinity rule. (default 1)
--kube-api-burst value	100	Burst to use while talking with kubernetes apiserver (default 100)
--kube-api-content-type string	application/vnd.kubernetes.protobuf	Content type of requests sent to apiserver. (default "application/vnd.kubernetes.protobuf")
--kube-api-qps value	50	QPS to use while talking with kubernetes apiserver (default 50)
--kubeconfig string		Path to kubeconfig file with authorization and master location information.
--leader-elect	true	Start a leader election client and gain leadership before executing the main loop. Enable this when running replicated components for high availability. (default true)
--leader-elect-lease-duration duration	15s	The duration that non-leader candidates will wait after observing a leadership renewal until attempting to acquire leadership of a led but unrenewed leader slot. This is effectively the maximum duration that a leader can be stopped before it is replaced by another candidate. This is only applicable if leader election is enabled. (default 15s)
--leader-elect-renew-deadline duration	10s	The interval between attempts by the acting master to renew a leadership slot before it stops leading. This must be less than or equal to the lease duration. This is only applicable if leader election is enabled. (default 10s)
--leader-elect-retry-period duration	2s	The duration the clients should wait between attempting acquisition and renewal of a leadership. This is only applicable if leader election is enabled. (default 2s)
--master string		The address of the Kubernetes API server (overrides any value in kubeconfig)
--policy-config-file string		File with scheduler policy configuration
--port value	10251	The port that the scheduler's http service runs on (default 10251)
--profiling	true	Enable profiling via web interface host:port/debug/pprof/ (default true)
--scheduler-name string	default-scheduler	Name of the scheduler, used to select which pods will be processed by this scheduler, based on pod's annotation with key 'scheduler.alpha.kubernetes.io/name' (default "default-scheduler")

kube-scheduler Configuration Best Practices

下面是我梳理的，个人认为必须关注的配置：

flag	default value	comments
--address string	0.0.0.0	The IP address to serve on (set to 0.0.0.0 for all interfaces) (default "0.0.0.0")
--kubeconfig string		Path to kubeconfig file with authorization and master location information.
--master string		The address of the Kubernetes API server (overrides any value in kubeconfig)
--policy-config-file string		File with scheduler policy configuration
--port value	10251	The port that the scheduler's http service runs on (default 10251)
--profiling	true	Enable profiling via web interface host:port/debug/pprof/ (default true)
