How to access configMap in GKE

[JonYu]

 Hi, I want to access the ConfigMap in my GKE cluster through Google Batch, but I can't find the relevant API in the GKE API documentation. What I can think of so far is to mount the ConfigMap in the GKE cluster to NFS for access. other better way?

Assuming you are trying to access the contents of a ConfigMap from within one or more containers running on GKE, you can actually mount ConfigMaps as volumes on your pods/containers:

ConfigMap:

apiVersion: v1 
kind: ConfigMap
metadata:
  name: special-config  
  namespace: default
data:
  SPECIAL_LEVEL: very 
  SPECIAL_TYPE: charm
  

Mount as volume:

...
spec:
  containers:
    - name: test-container
      image: registry.k8s.io/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

Hi,I see what you mean,but Google Batch is not part of GKE cluster, it's part of GCE, how to load ConfigMap into Google Batch?

Oh - I see.  So you have a GKE cluster and want to then use the same ConfigMap in GCE Batch?

Yes, can it be done?
