[HTCondor-users] Where are container images cached/stored?

[Matthew T West <m.t.west@xxxxxxxxxxxx>]

For those folks that support containers as run-time environments on their clusters, where are those images cached or stored?

1. When pulling from a remote repo like docker-hub in a htcondor submit file, is the image ultimately cached on the particular execute node where the job runs?
   
2. For those hosting/storing images locally, where do you usually put them?
1. Local storage on the Access Point
2. Shared (networked) central file system
3. The OSDF
4. Some bespoke local solution
   

Cheers,
Matt
