In vincentvanhees/rshiny_in_docker_test: R Shiny App For Testing Docker Integration

rshiny_in_docker_test

Repository to test using Rshiny in Docker with mounted volume

This repository aims to test the creation of a Docker container that has a Shiny app inside it that is able to write to a mounted volume. The app consists of only one button which, once clicked, tells the app to save a tiny text file to the mounted volume.

Installation

1. Install Docker
2. Clone this repository.
3. cd to the Docker folder of this repo.
4. docker build -t test-app . If you already have a rocker/shiny image then this should take less than a minute.

Run

1. docker run --rm -it -v ~/:/srv/shiny-server/data/ -p 3838:3838 -u shiny test-app
2. Open app in browser: http://localhost:3838/

Run in detached mode to check log file

1. docker run --rm -d -v ~/:/srv/shiny-server/data/ -p 3838:3838 -u shiny --name my-test-run test-app
2. docker exec -it my-test-run bash
3. Open app in browser: http://localhost:3838/
4. cd /var/log/shiny-server # Is shiny-server-shiny-*.log there? If yes, look inside/
5. When done, to remove all containers: docker container kill $(docker container ls -q)
