Storage

Storage and helm uninstall

Note that when a PVC is provisioned by installing the Helm chart, this will be bound to the chart, and data removed on uninstall.

To change this, configure the chart with the persistence.existingClaim option.

The Seq Docker container stores configuration and log events in its /data directory. For this directory to survive container restarts, it needs to be mapped to a persistent volume. In Kubernetes, this is covered by persistent volumes.

Seq is an IO-heavy workload, so the persistent volume used should be equivalent to local disk storage, for example an Azure Disks VHD or an AWS EBS volume. In cloud-managed Kubernetes services, there may be an existing storage class that corresponds to local disk storage. For example, in Azure there's a managed-premium storage class.

Setting a storage class in the persistence section of your Helm chart configuration will issue a persistent volume claim for that class of storage:

# config.yaml
persistence:
  storageClass: managed-premium

📘

Only one running Seq container can access a storage volume concurrently: it's not possible to run two or more container instances pointing to the same storage.
