I have made a custom scheduler like below:

```auto
root@kmaster:~# cat /etc/kubernetes/manifests/my-scheduler.yaml 
apiVersion: v1
kind: Pod
metadata:
  creationTimestamp: null
  labels:
    component: kube-scheduler
    tier: control-plane
  name: my-scheduler
  namespace: kube-system
spec:
  containers:
  - command:
    - kube-scheduler
    - --authentication-kubeconfig=/etc/kubernetes/scheduler.conf
    - --authorization-kubeconfig=/etc/kubernetes/scheduler.conf
    - --bind-address=127.0.0.1
    - --kubeconfig=/etc/kubernetes/scheduler.conf
    - --leader-elect=false
    - --port=10261
    - --secure-port=10269
    env:
    - name: no_proxy
      value: ',10.74.46.2,10.74.46.3,10.74.46.4'
    - name: NO_PROXY
      value: ',10.74.46.2,10.74.46.3,10.74.46.4'
    - name: HTTPS_PROXY
      value: http://127.0.0.1:3129
    - name: HTTP_PROXY
      value: http://127.0.0.1:3129
    image: k8s.gcr.io/kube-scheduler:v1.22.0
    imagePullPolicy: IfNotPresent
    livenessProbe:
      failureThreshold: 8
      httpGet:
        host: 127.0.0.1
        path: /healthz
        port: 10269
        scheme: HTTPS
      initialDelaySeconds: 10
      periodSeconds: 10
      timeoutSeconds: 15
    name: my-scheduler
    resources:
      requests:
        cpu: 100m
    startupProbe:
      failureThreshold: 24
      httpGet:
        host: 127.0.0.1
        path: /healthz
        port: 10269
        scheme: HTTPS
      initialDelaySeconds: 10
      periodSeconds: 10
      timeoutSeconds: 15
    volumeMounts:
    - mountPath: /etc/kubernetes/scheduler.conf
      name: kubeconfig
      readOnly: true
  hostNetwork: true
  priorityClassName: system-node-critical
  securityContext:
    seccompProfile:
      type: RuntimeDefault
  volumes:
  - hostPath:
      path: /etc/kubernetes/scheduler.conf
      type: FileOrCreate
    name: kubeconfig
status: {}
root@kmaster:~# 

```

My customer scheduler pod is running successfully:

```auto
root@kmaster:~# kubectl get pods -n kube-system
NAME READY STATUS RESTARTS AGE
coredns-78fcd69978-6dcft 1/1 Running 10 (2d19h ago) 47d

kube-scheduler-kmaster 1/1 Running 0 21h
my-scheduler-kmaster 1/1 Running 0 7h17m

```

Then created a pod using that scheduler:

```auto
root@kmaster:~# cat my_pod.yaml 
apiVersion: v1
kind: Pod
metadata:
  labels:
    run: webapp-color
  name: webapp-color
spec:
  containers:
  - image: 10.74.46.13:5000/webapp-color:v1
    name: webapp-color
  schedulerName: my-scheduler
root@kmaster:~# 

```

But my pod is in pending state:

```auto
root@kmaster:~# kubectl get pod
NAME READY STATUS RESTARTS AGE
webapp-color 0/1 Pending 0 4h12m
root@kmaster:~# 

```

Describe the pod:

```auto
root@kmaster:~# kubectl describe pod webapp-color
Name: webapp-color
Namespace: default
Priority: 0
Node: <none>
Labels: run=webapp-color
Annotations: <none>

    Port: <none>
    Host Port: <none>
    Environment: <none>
    Mounts:
      /var/run/secrets/kubernetes.io/serviceaccount from kube-api-access-mkh4z (ro)
Volumes:
  kube-api-access-mkh4z:
    Type: Projected (a volume that contains injected data from multiple sources)
    TokenExpirationSeconds: 3607
    ConfigMapName: kube-root-ca.crt
    ConfigMapOptional: <nil>
    DownwardAPI: true
QoS Class: BestEffort
Node-Selectors: <none>
Tolerations: node.kubernetes.io/not-ready:NoExecute op=Exists for 300s
                             node.kubernetes.io/unreachable:NoExecute op=Exists for 300s
Events: <none>
root@kmaster:~# 

```

Kubernetes version:

```auto
root@kmaster:~# kubectl version --short
Client Version: v1.22.0
Server Version: v1.22.0
root@kmaster:~# 

```

Please help me to find why pod is in pending state.  
Not getting any clue.

Pending means custom scheduler is not working. But not getting any reason.
