Upgrading the various components of Chronosphere Telemetry Pipeline gives you access to the latest features, fixes, and improvements.

​
Upgrade Core Operators and Core Instances

Use the information in this section to upgrade your Core Operators and Core Instances.
You must use the same method for upgrading your Core Operators and Core Instances that you used when you originally installed them.

​
Determine your upgrade method

The method you must use for upgrading your Core Operator and Core Instance depends on the method you used when you installed that Core Operator and Core Instance, which in turn depends on your environment.
If you installed Telemetry Pipeline in a Kubernetes cluster and aren’t sure whether you used Pipeline CLI or Helm during that installation process, run the following kubectl command:
kubectl -n calyptia get deploy calyptia-core-controller-manager --show-labels
The resulting output shows any labels attached to the controller-manager resource.
  • If the label app.kubernetes.io/managed-by=Helm is present, that means you used Helm to install Telemetry Pipeline and should continue to use Helm for any subsequent upgrades to your Core Operator and Core Instance.
  • If the label app.kubernetes.io/managed-by=Helm is not present, that means you used Pipeline CLI to install Telemetry Pipeline and should continue to use Pipeline CLI for any subsequent upgrades to your Core Operator and Core Instance.

​
Upgrade your Core Operator and Core Instance

After you determine your upgrade method, use the corresponding steps to upgrade your Core Operator and Core Instance to the latest available version.
If you deployed Telemetry Pipeline inside a Kubernetes cluster, Pipeline CLI must have access to that cluster. If you deployed Telemetry Pipeline on Linux, you must run Pipeline CLI from inside that Linux environment.
  1. Update Pipeline CLI. Because Core Operator and Core Instance versions are dependent on your Pipeline CLI version, you must use the latest version of Pipeline CLI to perform upgrades.
If you don’t update Pipeline CLI, subsequent steps will fail.
  1. Run the following command to install the latest version of Core Operator, which overwrites any previously installed versions: 
    calyptia install operator
    Optionally, you can use the --kube-namespace flag to set the Core Operator’s namespace.
  2. Run the following command to update your associated Core Instance: 
    calyptia update core_instance operator INSTANCE
    Replace INSTANCE with the name of the Core Instance you want to update.

​
Upgrade a pipeline

Regardless of what method you used to install and upgrade your Core Operator and Core Instance, you can use either the Telemetry Pipeline web interface or Pipeline CLI to upgrade pipelines.
There are two possible methods for upgrading pipelines in the Telemetry Pipeline web interface.Upgrade to the latest versionTo upgrade a pipeline to the latest version, follow these steps:
  1. Sign in to Telemetry Pipeline.
  2. Go to Core Instances, and then click the name of the pipeline you want to upgrade.
  3. If a pipeline isn’t using the latest agent version, an Upgrade to <version> available notice is displayed on the pipeline details page. Next to this notice, click Upgrade to upgrade the pipeline to the latest version.
This upgrade method always retains a pipeline’s current agent image type.
Choose the agent image type and versionTo choose the agent image type and version for your pipeline, follow these steps:
  1. Sign in to Telemetry Pipeline.
  2. Go to Core Instances, and then click the name of the pipeline you want to upgrade.
  3. Go to  Advanced Settings.
  4. In the Pipeline Image section, select an option from the Version drop-down menu. Version numbers with no suffix (for example, 1.2.3) use the Red Hat UBI agent image, and version numbers with the distroless suffix (for example, 1.2.3-distroless) use the distroless agent image.
  5. Click Apply to save your changes.

​
Upgrade multiple pipelines

To upgrade all of your pipelines in a given environment simultaneously, run the following command: 
curl -s https://raw.githubusercontent.com/chronosphereio/calyptia-cli/main/update-all-pipeline-images.sh | bash -s -- ghcr.io/calyptia/core/calyptia-fluent-bit:VERSION
Replace VERSION with the latest version of the pipeline agent. You can find this value in the Pipeline agent column of the Telemetry Pipeline component versions table. For example, if the latest version of the pipeline agent is 1.23.0, provide the value 1.23.0 to use the Red Hat UBI agent image or 1.23.0-distroless to use the distroless agent image.
For critical pipelines, Chronosphere recommends updating each pipeline individually instead of using this script.

Deployment strategies

Deployment strategies govern how a pipeline’s replicas behave during the upgrade process. For more information, see the deployment strategies guide.
