Use a secret to store sensitive data in helm kubernetes - kubernetes

Question

I have a secret.yaml file inside the templates directory with the following data:
apiVersion: v1
kind: Secret
metadata:
name: appdbpassword
stringData:
password: password
I also have a ConfigMap:
apiVersion: v1
kind: ConfigMap
metadata:
name: appdbconfigmap
data:
jdbcUrl: jdbc:oracle:thin:#proxy:service
username: bhargav
I am using the following pod:
apiVersion: v1
kind: Pod
metadata:
name: expense-pod-sample-1
spec:
containers:
- name: expense-container-sample-1
image: exm:1
command: [ "/bin/sh", "-c", "--" ]
args: [ "while true; do sleep 30; done;" ]
envFrom:
- configMapRef:
name: appdbconfigmap
env:
- name: password
valueFrom:
secretKeyRef:
name: appdbpassword
key: password
When I use the helm install command I see the pod running but if I try to use the environment variable ${password} in my application, it just does not work. It says the password is wrong. It does not complain about the username which is a ConfigMap. This happens only if I use helm. If I don't use helm and independently-run all the YAML files using kubectl, my application access both username and password correctly.
Am I missing anything here ?

Answer 1

apiVersion: v1
kind: Secret
metadata:
name: test-secret
data:
password : cGFzc3dvcmQK
You can also add the secret like this where converting data into base64 format. While stringData do it automatically when you create secret.
Trying Adding the secrets in environment like this way
envFrom:
- secretRef:
name: test-secret
