Set Working Directory

cd /Volumes/LocalDrive/Docker

Let's create a directory for our application

mkdir Docker

Lets Create Data loading script and place it in a folder

mkdir data-prep

touch data-prep/data-prep-script.R

Place the data inside the data-prep folder

Now Create APP.R file to build our application

mkdir shiny-app

touch shiny-app/app.R

After completing the app, place the saved RDS data file in this directory

Now Let's create RProj file for the application with default parameters

touch shiny-app-docker.Rproj

Time to create Dockerfile to build our docker

touch Dockerfile

Lets build our Docker Image

docker build -t my-shiny-app .

Run the docker

docker run --rm -p 3838:3838 my-shiny-app

Check the app running in docker

http://localhost:3838

Lets push our docker image to Azure

Login into Azure

az login

Create Azure Resource group and provide region

az group create --name shinyapps --location northeurope

Create Azure Container Service to host our Docker Image

az acr create -n shinyappdocker -g shinyapps --sku Basic

Create A Service plan for our application, choosing Linux Basic Free version

az appservice plan create -g shinyapps -n shinyappplan --sku FREE --is-linux

One more step to push docker to Azure

Log into Azure container registry

docker login shinyappdocker.azurecr.io

It will prompt for Username and Password

Log into Azure Portal in a browser, go to the resource group we created shinyapps ---> shinyappdocker ---> Access Keys --> Enable Admin User ---> copy Username and password

check for login succesful message

Tag the image of the docker to the Azure container registry

docker tag my-shiny-app shinyappdocker.azurecr.io/my-shiny-app

Push the docker image to the cloud

docker push shinyappdocker.azurecr.io/my-shiny-app

Time to deploy

az webapp create -g shinyapps -p shinyappplan -n myshinyappindocker -i shinyappdocker.azurecr.io/my-shiny-app

Once its deployed, get the link for the application
