How can print the logs in logstash, once after I add command and args in container.

```auto
containers:
        - name: logstash
          env:
            - name: LOGSTASH_PW
          image: docker.elastic.co/logstash/logstash-oss:7.7.1
          ports:
            - containerPort: 5044
          volumeMounts:
            - name: config-volume
              mountPath: /usr/share/logstash/config
          resources:
            limits:
              memory: 4Gi
              cpu: 2500m
            requests:
              memory: 4Gi
              cpu: 800m
          command: ["/bin/sh"]
          args: ["-c", "cd bin; logstash-plugin install logstash-filter-drop; sleep 1000;"]

```

it is just printing.

```auto

```auto
command: ["/bin/sh"]
args: ["-c", "cd bin; logstash-plugin install logstash-filter-drop; sleep 25; logstash"]

```

starting logstash after sleep worked for me.

Thanks
