Kubernetes Secret Creation - DBName, Username, Password and Encryption Key

In this section, you will learn to create a secret to store database name, username, password, and encryption key.

To create a Kubernetes secret:

1. Create a yaml file with dbname, dbusername, dbpassword, encryptionKey using the syntax given below:

   ocudr-secret.yaml
   apiVersion: v1
   kind: Secret
   metadata:
     name: ocudr-secrets
   type: Opaque
   data:
     dbname: dWRyZGI=
     dsusername: dWRydXNlcg==
     dspassword: dWRycGFzc3dk
     encryptionkey: TXkgc2VjcmV0IHBhc3NwaHJhc2U=

   The values of dbname, dsusername, dspassword, encryptionKey are base64 encoded. These are created by executing the following commands:

   echo -n "<db name>" | base64

   echo -n "<db username>" | base64

   echo -n "<db password>" | base64

   echo -n "<encryptionKey string>" | base64

   Note:

   You will create a secret using this yaml file.
2. Execute the following command to create a namespace where deployment is done.

   kubectl create namespace <namespace>

   Note:

   To create a secret, you need a namespace where deployment is done.
3. Execute the following command to create a secret:

   kubectl create -f <secret File Name> -n <namespace>

4. Execute the following command to verify a secret creation:

   kubectl describe secret <secret name> -n <namespace>
