I'm new to Kubernetes. In my project I'm trying to use Kustomize to generate configMaps for my deployment. Kustomize adds a hash after the configMap name, but I can't get it to also change the deployment to use that new configMap name.

Deployment:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: env-receiver-deployment
  labels:
    app: env-receiver-app
    project: env-project
spec:
  replicas: 1
  selector:
    matchLabels:
      app: env-receiver-app
  template:
    metadata:
      labels:
        app: env-receiver-app
        project: env-project
    spec:
      containers:
      - name: env-receiver-container
        image: eu.gcr.io/influxdb-241011/env-receiver:latest
        resources: {}
        ports:
        - containerPort: 8080
        envFrom:
        - configMapRef:
            name: env-receiver-config
        args: [ "-port=$(ER_PORT)", "-dbaddr=$(ER_DBADDR)", "-dbuser=$(ER_DBUSER)", "-dbpass=$(ER_DBPASS)" ]

kustomize.yml:

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
configMapGenerator:
- name: env-receiver-config
  literals:
  - ER_PORT=8080
  - ER_DBADDR=http://localhost:8086
  - ER_DBUSER=writeuser
  - ER_DBPASS=writeuser

Then I run kustomize, apply the deployment and check if it did apply the environment.

$ kubectl apply -k .
configmap/env-receiver-config-258g858mgg created
$ kubectl apply -f k8s/deployment.yml
deployment.apps/env-receiver-deployment unchanged
$ kubectl describe pod env-receiver-deployment-76c678dcf-5r2hl 
Name:               env-receiver-deployment-76c678dcf-5r2hl
[...]
    Environment Variables from:
      env-receiver-config  ConfigMap  Optional: false
    Environment:           <none>
[...]

But it still gets its environment variables from: env-receiver-config, not env-receiver-config-258g858mgg.

My current workaround is to disable the hash suffixes in the kustomize.yml.

generatorOptions:
  disableNameSuffixHash: true

It looks like I'm missing a step to tell the deployment the name of the new configMap. What is it?
