<p>Two pods are running and have different volume  mounts, but there is a need of using the same configmap in the 2 running pods.</p>

<p>Sure you can do that. You can mount same <code>ConfigMap</code> into different volume. You can take a look into <a href="https://kubernetes.io/docs/tasks/configure-pod-container/configure-pod-configmap/" rel="nofollow noreferrer">configure-pod-configmap</a>.</p>

<p>Say, your <code>ConfigMap</code> is like following:</p>

<pre><code>apiVersion: v1
kind: ConfigMap
metadata:
  name: special-config
  namespace: default
data:
  SPECIAL_LEVEL: very
  SPECIAL_TYPE: charm
</code></pre>

<p>And two pods:</p>

<pre><code>apiVersion: v1
kind: Pod
metadata:
  name: dapi-test-pod-01
spec:
  containers:
    - name: test-container
      image: busybox
      command: [ "/bin/sh", "-c", "ls /etc/config/" ]
      volumeMounts:
      - name: config-volume
        mountPath: /etc/config
  volumes:
    - name: config-volume
      configMap:
        # Provide the name of the ConfigMap containing the files you want
        # to add to the container
        name: special-config
  restartPolicy: Never
---
apiVersion: v1
kind: Pod
metadata:
  name: dapi-test-pod-02
spec:
  containers:
    - name: test-container
      image: busybox
      command: [ "/bin/sh", "-c", "ls /etc/config/" ]
      volumeMounts:
      - name: config-volume
        mountPath: /etc/config
  volumes:
    - name: config-volume
      configMap:
        # Provide the name of the ConfigMap containing the files you want
        # to add to the container
        name: special-config
  restartPolicy: Never
</code></pre>

<p>Now see the logs after creating the above <code>ConfigMap</code> and two <code>Pods</code>:</p>

<pre><code># for 1st Pod
$ kubectl logs -f dapi-test-pod-01
SPECIAL_LEVEL
SPECIAL_TYPE

# for 2nd Pod
$ kubectl logs -f dapi-test-pod-02
SPECIAL_LEVEL
SPECIAL_TYPE
</code></pre>
