bubble/bin/bpatchfull

#!/bin/bash
#
# Usage:
#
#     bpatchfull hostname [norestart]
#
#  hostname  : the hostname of the bubble node to update
#              Usually you will have an entry in ~/.ssh/config to set the username and ssh key
#  norestart : If present, do not restart the API server after updating the jar file
#
# Patch the bubble.jar on a remote node.
# This script updates the entire jar file, and takes a lot longer than bpatch
#
# You install the JDK on the remote node first: apt install openjdk-11-jdk-headless
#
