Step-by-Step Deployment Guides

Method 1: Deploy to shinyapps.io (Easiest - 10 minutes)

Prerequisites: - R and RStudio installed - A working Shiny app - Free account at shinyapps.io

Step 1: Install Required Packages

# Install the rsconnect package
install.packages("rsconnect")

Step 2: Configure Your Account

1. Log in to shinyapps.io
2. Click on your name → Tokens → Show → Copy to clipboard
3. In RStudio, run the configuration command (paste your token info):

library(rsconnect)

rsconnect::setAccountInfo(
  name='your-account-name',
  token='YOUR-TOKEN',
  secret='YOUR-SECRET'
)

Step 3: Deploy Your App

Navigate to your app directory and deploy:

# Set working directory to your app folder
setwd("/path/to/your/shiny/app")

# Deploy the application
rsconnect::deployApp(appName = "my-awesome-app")

Step 4: Verify Deployment

Your app will automatically open in a browser at: https://your-account.shinyapps.io/my-awesome-app

Pro Tips for shinyapps.io

• Use .Rbuildignore to exclude unnecessary files and reduce deployment time
• Monitor your active hours in the dashboard to avoid hitting limits
• Set appropriate instance sizes based on your app’s memory needs
• Use rsconnect::showLogs() to debug deployment issues

Method 2: Self-Host with Shiny Server (Ubuntu/Debian)

Prerequisites: - Ubuntu 20.04+ or Debian server (cloud VM or on-premise) - SSH access with sudo privileges - Domain name (optional but recommended)

Step 1: Install R

# Update package list
sudo apt update

# Install R
sudo apt install -y r-base r-base-dev

# Install essential build tools
sudo apt install -y gdebi-core libcurl4-openssl-dev \
  libssl-dev libxml2-dev

Step 2: Install Shiny and Required Packages

# Launch R as root
sudo R

# In R console:
install.packages('shiny')
install.packages('rmarkdown')
# Install your app-specific packages
# install.packages(c('dplyr', 'ggplot2', 'plotly', etc.))

# Quit R
q(save = "no")

Step 3: Download and Install Shiny Server

# Download Shiny Server (check for latest version at https://posit.co/download/shiny-server/)
wget https://download3.rstudio.org/ubuntu-18.04/x86_64/shiny-server-1.5.21.1012-amd64.deb

# Install Shiny Server
sudo gdebi shiny-server-1.5.21.1012-amd64.deb

Step 4: Configure Shiny Server

Edit the configuration file:

sudo nano /etc/shiny-server/shiny-server.conf

Basic configuration:

# Define the user we should use when spawning R Shiny processes
run_as shiny;

# Define a top-level server which will listen on a port
server {
  # Listen on port 3838
  listen 3838;

  # Define the location available at the base URL
  location / {
    # Host the directory of Shiny Apps stored in this directory
    site_dir /srv/shiny-server;

    # Log all Shiny output to files in this directory
    log_dir /var/log/shiny-server;

    # When a user visits the base URL rather than a particular application,
    # an index of the applications available in this directory will be shown.
    directory_index on;
  }
}

Step 5: Deploy Your App

# Create your app directory
sudo mkdir -p /srv/shiny-server/myapp

# Upload your app files (app.R or ui.R/server.R)
# Using SCP from your local machine:
# scp -r /path/to/local/app/* user@server:/tmp/myapp/

# Move files to shiny directory
sudo mv /tmp/myapp/* /srv/shiny-server/myapp/

# Set proper permissions
sudo chown -R shiny:shiny /srv/shiny-server/myapp
sudo chmod -R 755 /srv/shiny-server/myapp

Step 6: Restart Shiny Server and Access Your App

# Restart Shiny Server
sudo systemctl restart shiny-server

# Check status
sudo systemctl status shiny-server

# View logs if needed
sudo tail -f /var/log/shiny-server.log

Access your app at: http://your-server-ip:3838/myapp

Step 7: (Optional) Set Up Nginx Reverse Proxy with SSL

# Install Nginx and Certbot
sudo apt install -y nginx certbot python3-certbot-nginx

# Configure Nginx
sudo nano /etc/nginx/sites-available/shiny

Nginx configuration:

server {
    listen 80;
    server_name your-domain.com;

    location / {
        proxy_pass http://localhost:3838/;
        proxy_redirect http://localhost:3838/ $scheme://$host/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_read_timeout 20d;
        proxy_buffering off;
    }
}

Enable the site and get SSL:

# Enable site
sudo ln -s /etc/nginx/sites-available/shiny /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl restart nginx

# Get SSL certificate
sudo certbot --nginx -d your-domain.com

Security Considerations

Shiny Server Open Source does not include built-in authentication. For production apps with sensitive data, consider: - Using Nginx with HTTP basic authentication - Implementing ShinyProxy for container-based authentication - Upgrading to Shiny Server Pro or Posit Connect - Using OAuth proxy like oauth2-proxy

Method 3: Docker Deployment (Portable and Reproducible)

Prerequisites: - Docker installed on your local machine or server - Basic understanding of Docker concepts - Your Shiny app ready

Step 1: Create a Dockerfile

In your app directory, create a file named Dockerfile:

# Use the Rocker Shiny image
FROM rocker/shiny:4.3.2

# Install system dependencies
RUN apt-get update && apt-get install -y \
    libcurl4-openssl-dev \
    libssl-dev \
    libxml2-dev \
    && rm -rf /var/lib/apt/lists/*

# Install R packages
RUN R -e "install.packages(c('shiny', 'shinydashboard', 'dplyr', 'ggplot2', 'plotly'), repos='https://cran.rstudio.com/')"

# Copy the app to the image
COPY . /srv/shiny-server/myapp/

# Make sure the app directory is readable
RUN chmod -R 755 /srv/shiny-server/myapp

# Expose port
EXPOSE 3838

# Run the Shiny Server
CMD ["/usr/bin/shiny-server"]

Step 2: Create .dockerignore

Exclude unnecessary files:

.git
.Rproj.user
.Rhistory
.RData
*.Rproj

Step 3: Build the Docker Image

# Build the image
docker build -t my-shiny-app .

# Verify the image was created
docker images

Step 4: Run the Container Locally

# Run the container
docker run -d -p 3838:3838 --name shiny-app my-shiny-app

# Check if it's running
docker ps

# View logs
docker logs shiny-app

Access your app at: http://localhost:3838/myapp

Step 5: Deploy to Cloud

Option A: Deploy to DigitalOcean

# Install doctl (DigitalOcean CLI)
# Create a DigitalOcean account and API token

# Tag your image for DigitalOcean Container Registry
docker tag my-shiny-app registry.digitalocean.com/your-registry/my-shiny-app

# Push to registry
docker push registry.digitalocean.com/your-registry/my-shiny-app

# Create a droplet and deploy via DigitalOcean App Platform or manually

Option B: Deploy to AWS Elastic Container Service (ECS)

# Install AWS CLI and configure credentials
aws configure

# Create ECR repository
aws ecr create-repository --repository-name my-shiny-app

# Authenticate Docker to ECR
aws ecr get-login-password --region us-east-1 | \
  docker login --username AWS --password-stdin YOUR_ACCOUNT_ID.dkr.ecr.us-east-1.amazonaws.com

# Tag and push
docker tag my-shiny-app:latest YOUR_ACCOUNT_ID.dkr.ecr.us-east-1.amazonaws.com/my-shiny-app:latest
docker push YOUR_ACCOUNT_ID.dkr.ecr.us-east-1.amazonaws.com/my-shiny-app:latest

# Create ECS task definition and service through AWS Console or CLI

Option C: Deploy to Google Cloud Run (Serverless)

# Install gcloud CLI and authenticate
gcloud auth login

# Set project
gcloud config set project YOUR_PROJECT_ID

# Deploy directly from Dockerfile
gcloud run deploy my-shiny-app \
  --source . \
  --platform managed \
  --region us-central1 \
  --allow-unauthenticated

Docker Best Practices

• Use specific version tags (e.g., rocker/shiny:4.3.2) instead of latest
• Create a renv.lock file for reproducible package management
• Use multi-stage builds to reduce image size
• Set resource limits in production (docker run -m 512m --cpus=1)
• Implement health checks in your Dockerfile

Method 4: AWS EC2 with Shiny Server (Scalable Cloud)

Step 1: Launch EC2 Instance

1. Log in to AWS Console → EC2
2. Click “Launch Instance”
3. Choose Ubuntu Server 22.04 LTS (Free tier eligible)
4. Select instance type (t2.micro for testing, t2.small+ for production)
5. Configure security group:
   • SSH (port 22) - Your IP only
   • HTTP (port 80) - Anywhere
   • HTTPS (port 443) - Anywhere
   • Custom TCP (port 3838) - Anywhere (temporarily)
6. Create or select a key pair
7. Launch instance

Step 2: Connect and Install

# Connect via SSH
ssh -i your-key.pem ubuntu@your-ec2-public-ip

# Update system
sudo apt update && sudo apt upgrade -y

# Follow "Method 2" steps above to install R and Shiny Server

Step 3: Configure Elastic IP (Optional but Recommended)

1. In EC2 Console → Elastic IPs
2. Allocate new address
3. Associate with your instance
4. Update DNS records to point to Elastic IP

Step 4: Set Up Application Load Balancer (For High Traffic)

1. Create Target Group pointing to your EC2 instance(s)
2. Create Application Load Balancer
3. Configure SSL certificate using AWS Certificate Manager
4. Point your domain to the load balancer

Step 5: Enable Auto Scaling (Optional)

1. Create AMI from your configured instance
2. Create Launch Template
3. Create Auto Scaling Group
4. Set scaling policies based on CPU or memory utilization

AWS Cost Optimization

• Use Reserved Instances for predictable workloads (save up to 72%)
• Consider Spot Instances for non-critical apps (save up to 90%)
• Set up billing alerts
• Use AWS Cost Explorer to monitor spending
• Implement auto-shutdown for development instances

Advanced Topics

Setting Up Authentication

Option 1: Basic Authentication with Nginx

# Install apache2-utils
sudo apt install apache2-utils

# Create password file
sudo htpasswd -c /etc/nginx/.htpasswd username

# Update Nginx configuration
location / {
    auth_basic "Restricted Access";
    auth_basic_user_file /etc/nginx/.htpasswd;
    proxy_pass http://localhost:3838/;
}

Option 2: ShinyProxy (Containerized with Auth)

ShinyProxy runs each Shiny app in a separate Docker container and provides authentication.

# application.yml
proxy:
  port: 8080
  authentication: simple
  users:
  - name: user1
    password: password1
  docker:
    url: http://localhost:2375
  specs:
  - id: myapp
    display-name: My Shiny App
    container-image: my-shiny-app
    container-cmd: ["R", "-e", "shiny::runApp('/srv/shiny-server/myapp')"]
    port: 3838

Performance Optimization

1. Enable caching for expensive computations
2. Use async processing with promises and future packages
3. Optimize reactive expressions - use reactive() vs observe() appropriately
4. Database connection pooling with pool package
5. Implement CDN for static assets
6. Use profiling tools: profvis package
7. Consider load balancing for multiple instances

Monitoring and Logging

Application Monitoring:

# Add to your server.R
library(shinyjs)
library(futile.logger)

flog.threshold(INFO)
flog.appender(appender.file('/var/log/shiny-server/myapp.log'))

# Log user actions
observeEvent(input$button, {
  flog.info(paste("Button clicked by user:", session$user))
})

Server Monitoring:

• Uptime monitoring: UptimeRobot, Pingdom
• Application monitoring: Google Analytics, Plausible
• Server metrics: CloudWatch (AWS), Prometheus + Grafana
• Log aggregation: ELK Stack, Papertrail

Continuous Deployment

GitHub Actions Example:

# .github/workflows/deploy.yml
name: Deploy to shinyapps.io

on:
  push:
    branches: [main]

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2

      - name: Setup R
        uses: r-lib/actions/setup-r@v2

      - name: Install dependencies
        run: |
          install.packages('rsconnect')
          install.packages('shiny')
        shell: Rscript {0}

      - name: Deploy to shinyapps.io
        env:
          SHINYAPPS_ACCOUNT: ${{ secrets.SHINYAPPS_ACCOUNT }}
          SHINYAPPS_TOKEN: ${{ secrets.SHINYAPPS_TOKEN }}
          SHINYAPPS_SECRET: ${{ secrets.SHINYAPPS_SECRET }}
        run: |
          rsconnect::setAccountInfo(
            name = Sys.getenv("SHINYAPPS_ACCOUNT"),
            token = Sys.getenv("SHINYAPPS_TOKEN"),
            secret = Sys.getenv("SHINYAPPS_SECRET")
          )
          rsconnect::deployApp(appName = "myapp")
        shell: Rscript {0}

Troubleshooting Common Issues

Issue 1: Package Installation Failures

Problem: Deployment fails due to missing system dependencies

Solution:

# For Ubuntu/Debian - install common dependencies
sudo apt install -y \
  libcurl4-openssl-dev \
  libssl-dev \
  libxml2-dev \
  libfontconfig1-dev \
  libharfbuzz-dev \
  libfribidi-dev \
  libfreetype6-dev \
  libpng-dev \
  libtiff5-dev \
  libjpeg-dev

Issue 2: Shiny Server Won’t Start

Problem: Server fails to start or apps show errors

Solution:

# Check Shiny Server status
sudo systemctl status shiny-server

# Check logs
sudo tail -100 /var/log/shiny-server.log

# Check app-specific logs
sudo tail -100 /var/log/shiny-server/myapp-shiny-*.log

# Verify R can load your packages
sudo su - shiny -c "R -e \"library(your_package)\""

Issue 3: WebSocket Connection Failures

Problem: App loads but doesn’t respond to interactions

Solution: - Ensure your proxy supports WebSocket connections - Add WebSocket headers to Nginx/Apache config (shown in Method 2) - Check firewall isn’t blocking WebSocket traffic - Verify proxy_read_timeout is set appropriately

Issue 4: Memory Errors

Problem: App crashes with “cannot allocate vector” errors

Solution: - Increase instance/server memory - Optimize R code to use less memory - Implement data pagination - Use database queries instead of loading full datasets - Consider using data.table instead of data.frame
