  namespace: sms-service
spec:

      app: sms-service
  replicas: 4 # tells deployment to run 2 pods matching the template
  template:
    metadata:

Set the SPRING_PROFILES_ACTIVE environment variable to the profile(s) you want to run.

You can set it in the deployment yaml or at build time in your image but usually better to add it to deployment.

Create a new file, named configmap.yaml under the k8s config folder and add the following lines:

apiVersion: v1
kind: ConfigMap
metadata:
  name: blabla
  namespace: bla
data:
  application.yaml: |
    spring:
      profiles:
        active: prod (here goes the profile)

This tells Kubernetes to set this configuration when starting the container
