How to use kubernetes secrets in nodejs application?
Yourkubernetes.yaml
file specifies which environment variable to store your secret so it is accessible by apps in that namespace.
Using kubectl secrets cli interface you can upload your secret.
kubectl create secret generic -n node-app test-mongodb-secret --from-literal=username=a-username --from-literal=password=a-secret-password
(the namespace arg -n node-app
is optional, else it will uplaod to the default namespace)
After running this command, you can check your kube dashboard to see that the secret has been save
Then from you node app, access the environment variable process.env.SECRET_PASSWORD
Perhaps in your case the secretes are created in the wrong namespace hence why undefined
in yourapplication.
EDIT 1
Your indentation for container.env
seems to be wrong
apiVersion: v1kind: Podmetadata: name: secret-env-podspec: containers: - name: mycontainer image: redis env: - name: SECRET_USERNAME valueFrom: secretKeyRef: name: mysecret key: username - name: SECRET_PASSWORD valueFrom: secretKeyRef: name: mysecret key: password restartPolicy: Never
