How To
Summary
How to configure Instana Agent Environment Variables in a Kubernetes or OpenShift environment when deployed via Helm chart version 1.x.
NOTE: This will not work when the agent is deployed via Helm chart version 2.x
Steps
1. You will be able to see a list of the available environment variables for a host agent here
www.ibm.com/docs/en/instana-observability/current?topic=references-environment-variables
2. Access the Kubernetes cluster and make a backup of the current DaemonSet
Example:
kubectl get ds instana-agent -n instana-agent -o yaml > instana-agent_ds_backup.txt
3. Update the DaemonSet with the correct environment variable
Example:
kubectl edit ds instana-agent -n instana-agent
4. Here is an example configuration where the host agent version is pinned to a specific version using the environment variable name: INSTANA_AGENT_UPDATES_VERSION:
5. Ensure the variable being added is correctly indented and save the file.
NOTE: The instana agent does not have to be restarted for the environment variable configuration to take effect
