Upstream have many bugs about that... Here are just a few (I've seen more
of those...):
https://github.com/distribution/distribution/issues/1844
https://github.com/distribution/distribution/issues/2190
Even with "docker-registry garbage-collect" some images are never deleted...
Also have a look at the following project (there are more but this one works)
- it have more relevant upstream bugs referenced:
https://github.com/mortensteenrasmussen/docker-registry-manifest-cleanup
I'm not sure about the following one:

But Docker Registry is also the single point of failure.
In otherwise redundant cluster such as Nomad one can strive to avoid
single point of failure. Network share on clustered file systems
(e.g. MooseFS, LizardFS, GfarmFS, etc.) can be more reliable than
a NFS share from single server or a single instance of Docker Registry.
