Upgrade Notices
Important: If alloy is enabled (addons.alloy.enabled set to true) in the Alloy package, upgrading to Big Bang <insert release/TBD> requires migrating the Alloy package from the monitoring namespace to its own alloy namespace. Due to how Flux handles HelmRelease updates, some lingering resources will not be automatically removed. These resources must be deleted manually or through automation.
The Alloy autoRollingUpgrade feature provides an automated upgrade job that deletes any resources with the helm.toolkit.fluxcd.io/name=alloy label in the monitoring namespace. This migration process completely removes Alloy from the monitoring namespace and performs a clean installation in the new alloy namespace.
If autoRollingUpgrade.enabled is set to true in values.yaml, a post-upgrade job will automate the removal of all Alloy resources with the helm.toolkit.fluxcd.io/name=alloy label in the monitoring namespace. In this case, no additional action is required. However, a brief outage is expected during the upgrade as the Alloy migration is applied.
If you prefer to manually complete the pre-upgrade steps, set Values.autoRollingUpgrade.enabled=false in values.yaml and follow the steps outlined below. The following commands assume that the Alloy package is deployed in the default Big Bang monitoring namespace. Verify the namespace of your Alloy deployment before proceeding.
1. List all resources with the helm.toolkit.fluxcd.io/name=alloy label
Run the following command to output all alloy resources including CRD objects in the monitoring namespace:
kubectl api-resources --verbs=list --namespaced -o name | xargs -n 1 kubectl get --show-kind --ignore-not-found -l helm.toolkit.fluxcd.io/name=alloy -n monitoring
2. Delete the resources with the helm.toolkit.fluxcd.io/name=alloy label
From the list above, delete the alloy resources from the monitoring namespace.
kubectl delete <resource type> <resource name>-n monitoring
