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 Docker Deployment Overview.

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.

🚧

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. This is true even when one instance is shutting down and another is starting up. One instance of Seq must be fully stopped before another can be started.
