Sometimes it may be necessary to extract the images from a DTR volume backup. In the absence of a functioning DTR cluster, it's possible to extract these images using the open-source registry image.

First, identify the registry volume that needs to be extracted:

root@dtr-node1:~# docker volume ls --filter=name=dtr
DRIVER              VOLUME NAME
local               dtr-ca-a2382528a00b
local               dtr-postgres-a2382528a00b
local dtr-registry-a2382528a00b
