I am checking how to use statefullset on kubernet to deploy my service. In stateFullSet, I able to know the pods names because it would be always the stateFullSet name + a sequence number like:

app-0
app-1
app-2

so I would like to have a specific configuration in configMap for each pod and the pod would reading the config map based on the pod hostname.

It would be something like:

spec:
  containers:
    - name: cgwcontainer
      image: helioay/nginx
      volumeMounts:
      - name: config-volume
        mountPath: /opt/app/config
  volumes:
    - name: config-volume
      configMap:
        # Provide the name of the ConfigMap containing the files you want
        # to add to the container
        name: "pod_host_name"

I have seen that I can get the pod hostname based on the POD information "metadata.name" , but I am not sure if I am able to use this information as configMap name value. I know it is possible to set environment variables like:

      env:
        - name: NAME
          valueFrom:
            fieldRef:
              fieldPath: metadata.name

Is it possible to use similar solution but for the configMap name?

Thanks.
