Re: [kubernetes-users] usage of config-maps in gke deployments

['Ahmet Alp Balkan' via Kubernetes user discussion and Q]

I can't reproduce your problem./ I see the KUBE_CONFIG_1 and _2 just fine
when I deploy this pod.

I just created configmap:

kubectl create configmap test-configmap --from-literal=data-1=foo
--from-literal=data-2=bar

If you're seeing a crashloopbackoff, it probably doesn't have anything to
do with "command".

Do "kubectl describe -f FILE.yaml" to see why it's crashing. It probably
can't find the configmap or one of its keys.

[kubernetes-users] usage of config-maps in gke deployments

[ramueswari123]

I have created config-map and I am using the following yaml file to create a 
pod which uses the data as env variables but I am getting crashloopbackoff. 
When I remove the " command: [ "/bin/sh", "-c", "env" ]". It is running but i 
did not see any env variables in the pod. "echo $KUBE_CONFIG_1". It shows up 
blank. Can you please help me resolving this. (MY reqyuirement is to use env 
variables in configmap and attach it to the pod).

apiVersion: v1
kind: Pod
metadata:
  name: config-env-test-pod
spec:
  containers:
- name: test-container
  image: gcr.io/google_containers/busybox
  command: [ "/bin/sh", "-c", "env" ]
  env:
- name: KUBE_CONFIG_1
  valueFrom:
configMapKeyRef:
  name: test-configmap
  key: data-1
- name: KUBE_CONFIG_2
  valueFrom:
configMapKeyRef:
  name: test-configmap
  key: data-2
