This project aims to ease some of the pains encountered when attempting to sync VM templates in a [VMware vSphere Content Library](https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vm_admin.doc/GUID-254B2CE8-20A8-43F0-90E8-3F6776C2C896.html) to a large number of geographically-remote sites under less-than-ideal networking conditions.

(For extra credit, you can export the `./data/library/` path as an NFS share and mount that as a datastore in vSphere. This would make it an easy target for a CI/CD pipeline to crank out new/updated templates on a regular schedule, and those would then be automatically available to the `library-syncer` clients without any additional effort. If you do this, you'll want to set the NFS `anonuid` option in `/etc/exports` to match the `syncer` UID to control how the permissions get squashed. *Just a thought.*)
