R Epi Analytics Template

Docker, Trivy, and R Shiny offer a powerful tech stack for developing, containerizing, securing, and deploying web applications. With straightforward installation and deployment processes, even users with no prior experience can leverage these tools for robust application development and deployment.

Getting Started

Application Requirements

Before running the R Shiny application and using Docker and Trivy, you'll need to install the necessary software and dependencies. Below are the installation instructions for each application:

How to Run the Application

Once you have installed R, Docker, and Trivy, you can run the R Shiny application using Docker:

Navigate to the Application Directory (src/app): Open a terminal or command prompt and go to src/App. 

1
cd app/

Run this command in the terminal Build and Run Docker Containers: 

1
docker compose up

This starts the Docker containers and deploys the R Shiny application.

Making changes to the app.R file

When making changes to the app.R file, you'll need to run the following command to see the updates live on the application hosted at localhost:3838 

1
docker compose down && docker compose up

By running docker compose down && docker compose up, you ensure that your Docker containers are properly stopped, any changes to your code are applied, and then the containers are restarted with the updated code. This approach helps you see the changes in your application without needing to manually stop and start the containers.
