Storage

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 using -v on the command-line, as in the example above.

Seq is a database; the volume provided to it 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:

helm install -f config.yaml my-seq datalust/seq

# 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.
