Repo has been updated to include the following:
Dockerfile.cloudron and start.sh to match Cloudron app standardsI've tested backup,restore and package upgrade.

Thanks!
I'm a long-time Node-RED user. I was able to get a custom app packaged for Cloudron. So far, so good...
@girish Ok, I understand a bit more about the Cloudron build process now. I have updated my Dockerfile.cloudron and moved the repo here:
https://github.com/jsonsmth/node-red-docker-cloudron
The updated build process stores all app code in /app/code and only the user-specific data (including user node_modules) in /app/data.
I have updated the repo here with built-in LDAP auth:
@robi Cloudron customizations are in the docker-custom folder
https://github.com/jsonsmth/node-red-docker
Feedback is welcome as this is my first foray into Cloudron app customization.
@girish Also, I think we're following along with the recommended method for preserving user data within the app:
https://github.com/jsonsmth/node-red-docker-cloudron#managing-user-data
Here's a similar idea that has the hardware part mostly figured out:
@girish Thank you for the recommendation. I have tried on another bare metal server running Docker and I am able to access the external host IP from the Docker container. This is clearly a network issue with the host where I have Cloudron installed.
@staypath Continuing my conversation with myself 
Posting this here in case anyone else comes across this with the same question: I found that configuring fail2ban to use systemd was the trick:
[sshd]
port = ssh
#logpath = %(sshd_log)s
#backend = %(sshd_backend)s
backend = systemd
enabled = true
maxretry = 1
bantime = 14d
@girish Yes. Any new "plugins" installed are node modules that would be installed in /app/data/data/node_modules
I installed a couple of Node-RED modules (plugins), took a backup of the app in Cloudron, cloned the app from backup, etc... and all seemed to work well. Anything I'm missing? Thanks!
@Aizat Thanks for mentioning this awesome software! Someone has pinged the author about creating a Cloudron app. Hopefully it will happen...
@d19dotca works well for contacts on iOS and Android. I don't use it for calendars.
