The Global Settings section of the Settings page for SAS Event Stream Processing Studio and SAS Event Stream Manager enables an administrator to add environment variables. These environment variables are set for every ESP server that is created by the ESP operator. The environment variables are saved in the sas-esp-operator ESPConfig custom resource. This ESPConfig custom resource is originally created during the deployment of SAS Event Stream Processing. If the deployment is redeployed due to a configuration change, patch update, or version update, then the ESPConfig custom resource is returned to its original state. In this scenario, the environment variables that were added or changed by an administrator are not persisted.  

To persist environment variables after redeploying, use one of following methods:

Method 1 (For SAS^® Viya^® Deployments or Lightweight Deployments)

1. Save the ESPConfig element for the sas-esp-operator with the updated global settings to a file in the /tmp directory:

2. Verify that the Kubernetes resources file will apply cleanly:

3. Redeploy.
4. Apply Kubernetes resources from the file:

Method 2 (For SAS^® Viya^® Deployments Only)

Follow the directions in the $deploy/sas-bases/examples/sas-esp-operator/ESPConfig/README.md file to configure the environment variables during the deployment with a transformer. See Deploying with Other SAS Products for more information.
