Deploying Care on DigitalOcean

In this guide, we'll walk you through deploying Care on DigitalOcean. We'll keep things simple so you can follow along to get your instance up and running. Expect the process to take about an hour, depending on your familiarity with the tools.

For an overview of all supported cloud providers and their infrastructure requirements, see the Cloud providers overview.

Prerequisites

• A DigitalOcean account ([https://www.digitalocean.com Sign up here]).
• A fork of the Care backend and frontend repositories.
• A registered domain name (optional but recommended).
• Basic familiarity with DigitalOcean's App Platform and Spaces.

---

What You'll Be Doing

• Set up a PostgreSQL database for secure data storage.
• Configure DigitalOcean Spaces for handling files and media.
• Deploy the Care backend with Redis and Celery for task management.
• Set up the Care frontend for user access.
• Secure the setup with custom domains, API keys, and SSL.
• Setup a CI/CD Pipeline for Continuous Deployment.

---

Step 1: Create the Database

1.1 Navigate to Databases

• Log in to DigitalOcean and go to the Databases section.

1.2 Create a PostgreSQL Database

• Click Create Database.

• Choose the following:

  • Region: Select the nearest data center.
  • Engine: PostgreSQL (Version 16).
  • Resources: Select a plan based on your requirements.

  !Navigate to Databases

  • Name: Give your database a unique name.
  • Tags: Add tags for organization.

  !Navigate to Databases

  !Create Database

1.3 Save Connection Details

• Once the database is created, note the connection URL for later use.

  !Connection String

---

Step 2: Set Up Object Storage (Spaces)

2.1 Navigate to Spaces

• Go to the Spaces section in DigitalOcean.

2.2 Create a New Space

• Click Create a Space.

  !Create Space

• Choose:

  • Region: Select the same region as your database.
  • Enable CDN: For faster file delivery.
  • Bucket Name: Enter a unique name.
  • Project: Select the default project.
  • Create: Click to create the space.

  !Create Space

2.3 Generate API Keys

• Go to the API tab and click Spaces Keys.

• Create a new key pair and save the Key and Secret.

  !Generate Keys

---

Step 3: Deploy the Care Backend (BE)

Step 3.1: Deploy Redis

3.1.1 Set Up Redis

• Go to the App Platform and click Create App.

  !Select App Platform

• Choose Docker Hub as the source and use:

  • Repository: redis/redis-stack-server.
  • Tag: 6.2.6-v10.
  • Port: Expose 6379 as an internal port.

• Name the component redis.

  !Select App Platform

  !Edit these fields

3.1.2 Name and Deploy

• Name the App care-backend and deploy it.

  !Name and Deploy

---

Step 3.2: Deploy the Care Backend

3.2.1 Fork and Clone the Repository

• Fork the [https://github.com/ohcnetwork/care Care Backend Repository].
• Use the production branch for deployment.

3.2.2 Set Up the App

• Click Create App and choose From Source Code.

• Select your forked repo and branch.

• Set the build and run commands:

  !Create Resource from Source Code

  !Select GitHub Repository

  • Build Command:

    python install_plugins.py && python manage.py collectstatic --noinput && python manage.py compilemessages
    

  • Run Command:

    gunicorn config.wsgi:application --workers 2 --bind :9000
    

    !Select GitHub Repository

3.2.3 Environment Variables

Add the following as global environment variables:

DJANGO_SETTINGS_MODULE=config.settings.production
DATABASE_URL=<db-url> # Use the connection URL from Step 1.
REDIS_URL=redis://redis:6379
CORS_ALLOWED_ORIGINS=["https://care.example.com","http://localhost:4000","http://127.0.0.1:4000"]
CELERY_BROKER_URL=redis://redis:6379
REDIS_URL=redis://redis:6379
BUCKET_PROVIDER=DIGITAL_OCEAN
BUCKET_REGION=nyc3 # Use the region of your Spaces.
BUCKET_KEY= # Use the Spaces key.
BUCKET_SECRET= # Use the Spaces secret.
BUCKET_HAS_FINE_ACL=true
FILE_UPLOAD_BUCKET=example-space-ohc # Use the name of your Space.
FILE_UPLOAD_BUCKET_ENDPOINT=https://example-space-ohc.nyc3.digitaloceanspaces.com
FACILITY_S3_BUCKET=example-space-ohc # Use the name of your Space.
FACILITY_S3_BUCKET_ENDPOINT=https://example-space-ohc.nyc3.digitaloceanspaces.com
JWKS_BASE64= # Add your JWKS key. (Refer to the next section to create one.)
DISABLE_COLLECTSTATIC=1

Generate JWKS Key

The JWKS_BASE64 value is generated here. Use the generator below to create a key, then paste the output into the JWKS_BASE64 environment variable above.

<JwksGenerator />

3.2.4 Expose Ports

• Expose port 9000 for public HTTP access.

---

Step 3.3: Add a Domain for the Backend

3.3.1 Configure Domain

• Go to the app settings and add your domain (e.g., care-api.example.com).

• Update your DNS provider with the CNAME record.

  !Add Domain

---

Step 3.4: Set Up Celery Worker and Beat

3.4.1 Celery Worker

• Create a new component in the app.

• Use the following Run Command:

  celery --app=config.celery_app worker --max-tasks-per-child=2 --concurrency=2 --loglevel=DEBUG --logfile stdout
  

  !Celery Worker

  !Celery Worker

3.4.2 Celery Beat

• Create another component with the following Run Command:

  python manage.py migrate
  

  !Celery Job

  !Celery Job

---

Step 4: Deploy the Care Frontend (FE)

Step 5: Secure Database Access

5.1 Restrict Access

• Navigate to the Database settings.

• Add the Care backend app as a trusted source.

  !Secure Database

Step 6: Configure CORS for Spaces

6.1 Go to Bucket Settings

• Open your bucket in Spaces.

• Add the following CORS configuration:

  [
    {
      "AllowedHeaders": ["*"],
      "AllowedMethods": ["GET", "POST", "PUT", "DELETE"],
      "AllowedOrigins": ["https://example.com"],
      "ExposeHeaders": []
    }
  ]
  

  !CORS

Final Steps

• Verify Deployment:

  • Test the backend and frontend by accessing the respective domains.
  • Ensure all components (Redis, Celery Worker, Beat) are running.

• Optimize Security:

  • Use SSL certificates (e.g., Let's Encrypt) to enable HTTPS.

  • Configure firewall rules to restrict access.

    !Care Infra
