Shiny apps on docker

Docker for R Shiny Apps

Each folder in this repo contains a shiny app:

• un_migration: Navigate through the data distributed by the United Nations Department of Economic and Social Affairs

Applications

The shiny apps are composed of 2 files:

• ui.R handles all the UI related code.
• server.R deals with backend changes to update the UI.

Docker

The shiny apps can be run inside a docker container where the code and data have been copied into.

• Build the docker image: docker build -t ppjmartins/shiny_apps_img:latest .
• Run the app from docker: docker run -p 80:3838 ppjmartins/shiny_apps_img
• Check your browser at the address http://localhost:80/

It is possible to run the app on the docker image without copying the code and data with docker-compose. For that comment out the lines COPY app/ /srv/shiny-server/ and RUN chmod 777 /usr/bin/shiny-server.sh in the Dockerfile, rebuilt the image and finally run docker-compose up.
