An important thing to note here is that the name of the scheduler specified as an
argument to the scheduler command in the container spec should be unique. This is the name that is matched against the value of the optional `spec.schedulerName` on pods, to determine whether this scheduler is responsible for scheduling a particular pod.
In the above manifest, we have used a [Scheduler Configuration](/docs/reference/scheduling/config/)
to customize the behavior of your scheduler implementation. This configuration has been passed to
the `kube-scheduler` during initialization via its `--config` command line argument.
In the aforementioned Scheduler Configuration, your scheduler implementation has been represented via
a [KubeSchedulerProfile](/docs/reference/config-api/kube-scheduler-config.v1beta2/#kubescheduler-config-k8s-io-v1beta2-KubeSchedulerProfile).
An important thing to note here is that the name of the scheduler specified via `schedulerName` field of the defined `KubeSchedulerProfile`,
should be unique. This is the name that is matched against the value of the optional `spec.schedulerName` on pods, to determine whether
this scheduler is responsible for scheduling a particular pod.
Note also that we created a dedicated service account `my-scheduler` and bind the cluster role
`system:kube-scheduler` to it so that it can acquire the same privileges as `kube-scheduler`.
Please see the
[kube-scheduler documentation](/docs/reference/command-line-tools-reference/kube-scheduler/) for
detailed description of other command line arguments.
