jBPM docker Clustering with SQL help needed.

[Crimzin]

Dear Community,

If you would be so kind as to assist me.

I am trying to set up 3 servers to run as a HA cluster behind an nginX-proxy-manager.

I do not know which volumes is suppose to be on a DFS share to be a shared volume mapping between them.

I am struggling to find the correct documentation. any support would be greatly appreciated. my YML file for node 1 looks a follows:
