Dockerized Radiant

The repo is adapted from Flavio Barros' excellent shiny-wordclould example

This repo contains information to setup a dockerized instance of radiant. The radiant docker image is available from Docker Hub.

Install docker

• For Mac: https://docs.docker.com/docker-for-mac/
• For Windows: https://docs.docker.com/docker-for-windows/
• For Linux: https://docs.docker.com/engine/installation/

After installing Docker check that that it is running by typing docker in a terminal.

Run from the Docker Hub image

To run and install the dockerized radiant app on your computer use:

docker run --rm -p 80:80 vnijs/radiant

The app will be avaliable at http://127.0.0.1/

Alternatively, you can clone and run dockerized radiant using the steps below:

Cloning the repo

The first step is to clone the docker-radiant repo:

git clone https://github.com/radiant-rstats/docker-radiant.git

By default, file uploads are limited to 10MB and R-code in R > Report and R > Code will not be evaluated for security reasons. If you have appropriate security in place you can change these settings by editing .Rprofile in the docker-radiant repo you cloned. See example changes below:

options(radiant.maxRequestSize = -1)  ## no file size limit
options(radiant.report = TRUE)

Building the container

Use the terminal to change the working directory to the location where you cloned the repo. Then build the docker image using:

docker build -t yourname/radiant .

If you need to update your container, e.g., to get the latest version of radiant, just rerun the command above.

Note that creating the container will take some time as it has to pull and install ubuntu, R, shiny-server, etc. as well as all required R-packages

If the build fails for some reason you can remove it using:

docker rmi yourname/radiant

Run the app

To run the dockerized radiant app on your computer use:

docker run --rm -p 80:80 yourname/radiant

The app will be avaliable at http://127.0.0.1/

To run the container on another port, e.g., 3838, you can use:

docker run --rm -p 3838:80 yourname/radiant

Trouble shooting

If something went wrong you can access the container through the bash shell using:

docker run -t -i yourname/radiant /bin/bash
