r-shiny-infrastructure-poc

A proof-of-concept repo for deploying containerised R Shiny apps. See also respositories for building the auth image and the app images.

Usage:

With a working kubernetes cluster, you should be able to run:

$ terraform init
$ terraform plan
$ terraform apply

Design:

• The logic for deploying Apache + R Shiny is encapsulated in the shiny-app Terraform module.
• This module takes configuration by being invoked in the top-level main.tf file.
• The deployments.tf contains all the R-specific options to manage multiple deployments (image + access type for each R Shiny app).
• The deployment config could have different edit rights to the rest of the repository (see .github/CODEOWNERS)
• The module allows the R Shiny deployments to be scaled independently of each other.
• The module allows different R Shiny deployments to be authenticated differently.
• For the purposes of this POC, no Egress is configured; just NodePort services to make the auth deployments accessible via host ports.
• For the purposes of this POC, OIDC demo authentication has been provided using Auth0's free service.

Auth secrets:

This POC is configured to use Auth0 as an Identity Provider.

You'll need to provide appropriate secret values to Terraform, which will be bootstrapped into the Apache configuration:

# A starting point:
$ cp terraform.tfvars{.sample,}
