Deploy Shinyproxy via Docker Compose

It's a demo of

Setting up Shinyproxy via docker compose
Customizing the home page via a template (see shinyproxy/fragments/navbar.html)
Deploying a "proxy" app that forwards the traffic to the "global" app, which is deployed via docker compose service

Clone this repo to a local directory, e.g. /usr/wd/shinyproxy-docker-compose-example
Copy the shinyproxy jar file (downloaded from shinyproxy.io) to ./shinyproxy/shinyproxy.jar
You may want to tweak docker-compose.yml and shinyproxy/application.yml
Run docker-compose build to build the necessary images
Run docker-compose up -d to launch the apps
Direct to http://127.0.0.1:8080, you should see the shinyproxy running.

app-normal: This is a regular shinyproxy app. Each user will have his/her own apps. It means a new docker container will be lanuched for each user.
app-in-compose: This is like a shiny server app. This app is only lanuched once by docker compose. Shinyproxy will only run a "proxy" (nginx based) container, which redirect the traffic to the "global" app.
app-not-in-compose: The underlying app is the same as app-in-compose, except that it's like a normal shinyproxy app, so different user doesn't share the same global environment.
