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.
