Alibaba Cloud ACK install

SUSE Observability Self-hosted

Minimum volume size

Alibaba Cloud's Container Service for Kubernetes (ACK) enforces a minimum volume size of 20 GiB for disk-based PersistentVolumeClaims (PVCs). When deploying on ACK, Persistent Volume Claims (pvc) have to request at least 20Gi of storage. Failure to meet the 20Gi minimum may result in volume provisioning and failures during Helm deployment.

We provide a dedicated set of Helm values that adjusts all volume sizes to meet this requirement. If you're installing on ACK, use this file during installation:

# ack-values.yaml
zookeeper:
  persistence:
    size: 20Gi
stackstate:
  components:
    checks:
      tmpToPVC:
        volumeSize: 20Gi
    healthSync:
      tmpToPVC:
        volumeSize: 20Gi
      localpvc:
        size: 20Gi
    state:
      tmpToPVC:
        volumeSize: 20Gi
    sync:
      tmpToPVC:
        volumeSize: 20Gi
    vmagent:
      persistence:
        size: 20Gi
  experimental:
    storeTransactionLogsToPVC:
      volumeSize: 20Gi
  stackpacks:
    localpvc:
      size: 20Gi
    pvc:
      size: 20Gi
backup:
  configuration:
    scheduled:
      pvc:
        size: 20Gi

Please create a separate file for the ACK-specific values and use it during installation. For example, if you follow Kubernetes install documentation and save the above values in a file called ack-values.yaml, you can install Suse Observability with:

helm upgrade \
  --install \
  --namespace suse-observability \
  --values $VALUES_DIR/suse-observability-values/templates/baseConfig_values.yaml \
  --values $VALUES_DIR/suse-observability-values/templates/sizing_values.yaml \
  --values ack-values.yaml \
suse-observability \
suse-observability/suse-observability
