3.5.3 Create a Secret with Cookie Encryption Password for Kubernetes

In Kubernetes environment, the MicroTx Distributed Transactions console requires the session cookie to be encrypted. You must provide a cookie encryption password through a Kubernetes secret.

To encrypt the MicroTx Distributed Transactions console session cookie, create a Kubernetes secret with the cookie encryption password:

1. Launch a terminal and enter the following commands to base64 encode the cookie encryption password.

   echo -n "cookie-encryption-password" | base64 -w 0 

   Replace cookie-encryption-password with a password of your choice.

   Note:

   For Linux, add -w 0 to the command to remove line breaks.
   The base64 encoded value of the password is returned. Note down this value as you will need it later.
2. Paste the following code in any text editor or reuse the installation_directory/MicroTx-RELEASE/deployment-descriptors/helmcharts/resources/cookie-encryption-secret.yaml file.

   apiVersion: v1
       kind: Secret
       metadata:
         name: console-cookie-encryption-password-secret
       type: Opaque
       data:
         secret: base64_encoded_cookieEncryptionPassword

   Where,

   • console-cookie-encryption-password-secret is the name of the Kubernetes secret that you want to create. Note down this name as you will have to provide it later in the values.yaml file.
   • base64_encoded_cookieEncryptionPassword is the base64 encoded value of the password that you have generated in the previous step.
3. Save the file as a YAML file. For example, cookieEncryptionPassword.yaml.
4. Run the following command to create a Kubernetes secret in the namespace where you want to install MicroTx Distributed Transactions.

   Command syntax

   kubectl apply -f <filename> -n <namespace>

   The following sample command creates a Kubernetes secret with the name console-cookie-encryption-password-secret in the MicroTx namespace with the details that you have provided in the cookieEncryptionPassword.yaml file.

   kubectl apply -f cookieEncryptionPassword.yaml -n otmm

Note down the name of the secret, console-cookie-encryption-password-secret. You'll provide this name as the value for the console.tmmConsoleConfiguration.cookieEncryptionPasswordSecretName property in the values.yaml file.
