Volumes

Volumes

MSR uses these named volumes for persisting data:

Volume name

Description

dtr-ca-<replica_id>

Root key material for the MSR root CA that issues certificates

dtr-notary-<replica_id>

Certificate and keys for the Notary components

dtr-postgres-<replica_id>

Vulnerability scans data

dtr-registry-<replica_id>

Docker images data, if MSR is configured to store images on the local filesystem

dtr-rethink-<replica_id>

Repository metadata

dtr-nfs-registry-<replica_id>

Docker images data, if MSR is configured to store images on NFS

You can customize the volume driver used for these volumes, by creating the volumes before installing MSR. During the installation, MSR checks which volumes don’t exist in the node, and creates them using the default volume driver.

By default, the data for these volumes can be found at /var/lib/docker/volumes/<volume-name>/_data.
