Containerized Shiny app with multiple versions

This repo is used in the blog post: Update Existing Shiny Apps in ShinyProxy

Version 1

Bivariate scatterplot

# build
docker build -f Dockerfile-v1 -t analythium/correlation:v1 .

# test
docker run -p 4000:3838 analythium/correlation:v1

# push
docker push analythium/correlation:v1

Version 2

3D image using RGL

# build
docker build -f Dockerfile-v2 -t analythium/correlation:v2 .

# test
docker run -p 4000:3838 analythium/correlation:v2

# push
docker push analythium/correlation:v2

Tagging exercise

# untagged image
docker build -f Dockerfile-v1 -t analythium/correlation .
# :latest tag is added
docker image ls
# build v2
docker build -f Dockerfile-v2 -t analythium/correlation:v2 .
# :latest is still v1
docker image ls

# tag the untagged image with :v1
docker tag analythium/correlation analythium/correlation:v1
# now :v1 and :latest are aliases
docker image ls

# rebuild untagged (:latest) using v2
docker build -f Dockerfile-v2 -t analythium/correlation .
# tag the new image with :v2
docker tag analythium/correlation analythium/correlation:v2
# now :latest and :v2 are aliases
docker image ls

# push images
docker push analythium/correlation
docker push analythium/correlation:v1
docker push analythium/correlation:v2

# pull all images at once
docker images |grep -v REPOSITORY|awk '{print $1":"$2}'|xargs -L1 docker pull

Git based update

git clone https://github.com/analythium/shiny-correlation.git

cd shiny-correlation
git pull

cp application.yml /etc/shinyproxy

docker pull analythium/correlation:v1
docker pull analythium/correlation:v2

service shinyproxy restart

Multiple Shiny apps with Shiny Server

A Dockerfile that uses the rocker/shiny parent image to deploy both versions in the same container:

docker build -f Dockerfile-shiny-server -t analythium/correlation:v3 .

docker run -p 4000:3838 analythium/correlation:v3

docker push analythium/correlation:v3

The 2D version (v1) will be available at http://localhost:4000/app2d/. The 3D version (v2) will be available at http://localhost:4000/app3d/.
