How-To

To set up an environment for a PubApps R Shiny application.

Prerequisites

You already have a trial or a purchased PubApps or PrivApps instance, so storage and resources are available.
You know where you are going to be running the app (shared server, private VM, container VM with GPUs).
You are able to ssh into the respective server from a HPG login node.
You have a support ticket, which has details like the project username for pubapps/privapps you will use, which port your application should be listening on, what DNS record (project.rc.ufl.edu and projectdev.rc.ufl.edu) it is going to use.

ssh into your project account on the respective server (shared or VM)
Install mamba with miniforge https://github.com/conda-forge/miniforge for Linux. Log out and back in to initialize mamba.
Create an application environment in the respective project tree e.g. ${HOME}/myproject/prod/conda or ${HOME}/myproject/prod/conda. E.g.

mamba create -yp ${HOME}/myproject/prod/conda
mamba activate ${HOME}/myproject/prod/conda

mamba install r-shiny

Install any other R packages or conda packages you need for your application into the environment.

Clone your git repository with shiny app code into e.g. ${HOME}/myproject/prod/app
Configure your shiny app to run on a pre-selected port (and host if not running on the shared webserver).

Add a systemd startup script to run the app when the server is rebooted e.g. after security patches are applied or power is lost.
