Running a Bash Script Continuously Across Multiple Servers (Local, Jumpbox and Dev server) - node.js

Question

I wrote a bash script to build a docker container (a NODE JS app) at the end so that the application runs on a DEV server. The thing is that the bash script has to be run in stages across multiple servers i.e., we need to build the docker container in local, ssh to a jump box and rsync it over there and then rsync it from the jumpbox to the dev server and then ssh to it again (if this process is done manually).
If you look at step 5 in the BASH script below, the rsync gets completed and the script runs to SSH to the jumpbox server, however, the script stops over there and I am just logged in to the jumpbox.
Could someone let me know what is wrong with this bash script and how should I fix it?
Thank you in advance.
Best,

Once you've open an ssh session to the other box your local script stops because it's waiting for the ssh session to end. You're just left sitting at a command prompt on the remote box.
It looks like what you're intending to have happen is the commands following your ssh run on the remote box. To send the commands to the remote machine redirect them:
ssh ${enumber}#10.188.129.25 <<'ENDSSH'
# series of commands to
# run on remote host
ENDSSH
Consider running your script through Shellcheck — you've got several problems with it beyond the one you asked about.
