I recently posted a question on Stack Overflow having a similar issue. I followed the instructions provided in the answer of this post: How to get access to Kubernetes container environment variables from Next.js application?. However, even after calling my environment variables using process.env.USERNAME, I am still getting an undefined value. Is there something wrong with my deployment file? Below is a snippet of my deployment.yaml:
metadata:
namespace: <namespace>
releaseName: <release name>
releaseVersion: 1.0.0
target: <target>
auth:
replicaCount: 1
image:
repository: '<name of repository is here>'
pullPolicy: <always>
container:
multiPorts:
- containerPort: 443
name: HTTPS
protocol: TCP
- containerPort: 80
name: HTTP
protocol: TCP
env:
- name: USERNAME
valueFrom:
secretKeyRef:
name: my-username
key: username
- name: PASSWORD
valueFrom:
secretKeyRef:
name: my-password
key: password
- name: HOST
valueFrom:
secretKeyRef:
name: my-host
key: host
volumeMounts:
- name: config
mountPath: "/configMap"
readOnly: true
volume:
- name: config
configMap:
name: environmental-variables
resources:

nginx.ingress.kubernetes.io/session-cookie-name: <cookie-name>
nginx.ingress.kubernetes.io/session-cookie-expires: <number>
nginx.ingress.kubernetes.io/session-cookie-max-age: <number>
To address my concern, I also created a separate configMap.yaml file. Though I'm unsure if this is the correct approach. Here is how my configMap.yaml file looks like:
apiVersion: v1
kind: ConfigMap
metadata:
name: environmental-variables
data:
.env: |
USERNAME: <username>
PASSWORD: <password>
HOST: <host>
I would greatly appreciate any assistance in resolving this issue! Also, for security reasons, I am looking to store my environment variables as secrets without exposing them. The application I am working on is built using Node.js and Express framework. Thank you!
EDIT: Adding the Secrets part of my yaml file for reference:
secrets:
- name: environmental-variables
key: USERNAME
- name: environmental-variables
key: PASSWORD
This is how my Secrets yaml file appears:
kind: Secret
apiVersion: v1
metadata:
name: environmental-variables
namespace: tda-dev-duck-dev
data:
USERNAME: <username>
PASSWORD: <password>
