1. Before upgrade (deployment file):

Duplicate port Definitions  
**.Values.global.containerPorts.monitoringHttp**

```yaml
ports:
  - containerPort: {{.Values.global.containerPorts.queryServiceHttp}}
  protocol: TCP
 - containerPort: {{ .Values.global.containerPorts.monitoringHttp }}
  protocol: TCP
- containerPort: {{ .Values.global.containerPorts.javaDebugger }}
  protocol: TCP
- name: {{ .Values.global.cncMetricsName }}
  containerPort: {{ .Values.global.containerPorts.monitoringHttp }}
  protocol: TCP

```

Deployment extract:

```yaml
        ports:
        - containerPort: 8080
          protocol: TCP
        - containerPort: 8443
          protocol: TCP
        - containerPort: 9000
          protocol: TCP
        - containerPort: 9000
          name: cnc-metrics
          protocol: TCP

```

1. Pre- Upgrade:  
_ **Removed from deployment file:** _
  - containerPort: {{ .Values.global.containerPorts.monitoringHttp }}  
protocol: TCP

```yaml
ports:
  - containerPort: {{.Values.global.containerPorts.queryServiceHttp}}
  protocol: TCP
  - containerPort: {{ .Values.global.containerPorts.javaDebugger }}
  protocol: TCP
- name: {{ .Values.global.cncMetricsName }}
  containerPort: {{ .Values.global.containerPorts.monitoringHttp }}
  protocol: TCP

```

1. Post Upgrade:  
Deployment file output:

```yaml
- containerPort: 8000
  protocol: TCP

- containerPort: 5801
  protocol: TCP`

```

Why did **both the entries (monitoringHttp)** get removed during upgrade?  
I would like to have at least 1 entry present there for my app to work
