How to Create Secrets in Kubernetes

Similar to how to create a ConfigMap, we create secrets:

1. Using a file
2. Using command line

Sample file

apiVersion: v1
kind: Secret
metadata:
  name: mysecret
type: Opaque
data:
  username: YWRtaW4=
  password: MWYyZDFlMmU2N2Rm

Note that the fields in data field need to be encoded in base64.

So as an example echo “root” | base64

Using CLI

kubectl create secret generic db-user-pass \
    --from-literal=username=root \
    --from-literal=password='whatever'
