How to Backup/Restore TRAINS-server when moving from AMI to local machine

Question

I recently started using TRAINS, with the server in AWS AMI. We are currently using v0.9.0.

I would like to move the TRAINS-server to run on our on-premises kubernetes cluster. However, I don't want to lose the data on the current server in AWS (experiments, models, logins, etc...). Is there a way to backup the current server and restore it to the local server?

Thanks!

Since this package is quite new, I'm making sure we are both referring to the same one, TRAINS-server https://github.com/allegroai/trains-server (which I'm one of the maintainers)

Backup the persistent data folders in the TRAINS-server AMI distribution:

• MongoDB: /opt/trains/data/mongo/
• ElasticSearch: /opt/trains/data/elastic/
• File Server: /mnt/fileserver/

Once you have your Kubernetes cluster up, restore the three folders to a sharable location . When creating the TRAINS-server deployment yaml make sure you map the sharable location to the specific locations the container expects, eg /mnt/shared/trains/data/mongo:/opt/trains/data/mongo

Start the Kubernetes TRAINS-server , it should now have all the previous data/users etc.
