octoprint_deploy

These files provide a simple bash script for quickly deploying multiple octoprint instances on a single computer (Ubuntu/debian based systems).

How to use

Install Ubuntu on computer of interest.
Install Octoprint. You can follow the directions here: https://octoprint.org/download/ or here: https://community.octoprint.org/t/setting-up-octoprint-on-a-raspberry-pi-running-raspbian/2337
Start up Octoprint for the first time to setup a base instance profile. The base profile will be edited in several places with INSTANCE to allow modifications during deployment.
During setup, edit the restart script: sudo systemctl restart INSTANCE
After the initial setup is done, reload the server and edit the Additional Serial Port field: /dev/octo_INSTANCE
You can also edit the server name under apperance with: INSTANCE
STOP your currently running octoprint server (Ctrl+C in the terminal you started is sufficient)
Make sure whichever printer you are installing for is not plugged in via USB
Go to wherever you downloaded octoprint_deploy: $ cd octoprint_deploy
Run the bash script: $ sudo ./addnew_printer.sh
And follow the instructions. Defaults are shown in brackets:

UNPLUG PRINTER FROM USB

Enter the name for new printer/instance:

printer01

Port on which this instance will run (ENTER will increment last value in /etc/octoprint_ports):

Selected port is: 5000

Auto-detect printer serial number for udev entry?y

Plug your printer in via USB now (detection time-out in 2 min)

Serial number detected as: AL03M8MG

Octoprint instance template base folder [/home/paul/.octoprint]:

Do you want to proceed? y

This will do the following:

Copy everything in ~/.octoprint to ~/.printer01 with the modifications
Update udev rules so this printer will always be at port /dev/octo_printer01
Create, start, and enable the service printer01 to control that octoprint instance.

Because each octoprint instance is coming from the same source files, any global modifications you make to octoprint (adding/removing plugins, updating octoprint) are all automatically applied to all of your instances and will take effect when you restart that instance.
