Kubernetes

CubeAPM can be deployed on Kubernetes using the official Helm chart.

1. Add the CubeAPM Helm chart repository.

   helm repo add cubeapm https://charts.cubeapm.com
   # Use the following command to update if the repo is already added.
   helm repo update cubeapm

2. Copy the values.yaml file from the Helm chart repository to your local machine.

   helm show values cubeapm/cubeapm > values.yaml

3. Edit the values.yaml file to customize the configuration as per your requirements. See Configure CubeAPM section for details of all available configuration parameters.

4. Install CubeAPM using the following command:

   helm install cubeapm cubeapm/cubeapm -f values.yaml
   # Use the following command to update if CubeAPM is already installed.
   helm upgrade cubeapm cubeapm/cubeapm -f values.yaml

Increase volume size

warning

Depending on the configuration of the associated storage class, particularly its reclaimPolicy and allowVolumeExpansion, the volumes may get deleted and recreated while resizing. Please try the changes in a non-production environment first to avoid accidental data loss.

CubeAPM creates a StatefulSet. StatefulSets do not allow direct modification of volume size, so the following steps are needed:

1. Edit CubeAPM's PVCs. Do the following for each PVC.

   # Run `kubectl get pvc | grep cube` to get names of CubeAPM PVCs.
   kubectl edit pvc <name>
   # Update `spec.resources.requests.storage` to desired size.

2. Delete CubeAPM StatefulSet while leaving its pods.

   # Run `kubectl get sts | grep cube` to get names of CubeAPM StatefulSet.
   kubectl delete sts --cascade=orphan <name>

3. Update persistence.size in CubeAPM Helm Chart values.yaml file and redeploy. This will recreate the StatefulSet and then restart the pods one-by-one. Each pod's PVC wll be resized during retart.

   helm upgrade cubeapm cubeapm/cubeapm -f values.yaml
