Azure App Services Deployment

Microsoft Azure provides a streamlined deployment solution that complies with regulations while ensuring local data residency requirements.

For compliance details, visit Azure compliance documentation.

Azure App Services deployment is recommended for customers prioritizing compliance and minimal technical overhead.

Benefits

  • Comprehensive hosting solution for production environments
  • Simplified deployment process with minimal technical requirements
  • Regulatory compliance and data residency support

Requirements

Instance Sizing

Minimum requirements:

  • Basic B2 (3.5GB RAM, 2 vCPU) for testing/small deployments
  • Premium tier recommended for production (minimum 2 vCPUs)

The server utilizes multi-threading, so additional vCPUs will improve performance. Note that RAM beyond 16GB provides no additional benefits.

Replicas

Multi-replica (multi-instance) deployments are supported only with an Enterprise license. For all other license plans, ensure that only a single replica is used.

Automated Deployment

The simplest deployment method uses our pre-configured template:

  1. Click the Deploy to Azure button below
  2. Follow the Azure portal instructions
Deploy to Azure

In the Azure portal, proceed with the default pre-configured values. Adjust the application version as needed — refer to the releases page for a list of available versions.

Upgrading Sentinel

To upgrade your Sentinel deployment to a specific version:

Before Upgrading

  2. Review the changelog for any breaking changes or migration requirements
  1. Navigate to your App Service in Azure Portal
  2. Select Deployment Center from the left menu
  3. Under Settings, update the image source to:
    • Registry: ghcr.io
    • Image and tag: altcha-org/sentinel:<version> (e.g., altcha-org/sentinel:1.0.0)
  4. Click Save to trigger a redeployment

Manual Upgrade via CLI

  1. Connect to Azure CLI and authenticate:

    Terminal window
    az login

  2. Update to a specific version:

    Terminal window
    az webapp config container set --name <your-app-name> \
    --resource-group <your-resource-group> \
    --docker-custom-image-name ghcr.io/altcha-org/sentinel:<version>

    Replace <version> with the exact tag (e.g., 1.0.0)

  3. Restart the app service:

    Terminal window
    az webapp restart --name <your-app-name> --resource-group <your-resource-group>

Version Verification

  1. Confirm the deployed version:

    Terminal window
    az webapp config container show --name <your-app-name> \
    --resource-group <your-resource-group> \
    --query "docker_image_name"

  2. Verify in the web interface:

    • Access https://[your-app-name].azurewebsites.net/v1/ping
    • Should return the expected version number

Rollback Procedure

To revert to a previous version:

Terminal window
az webapp config container set --name <your-app-name> \
--resource-group <your-resource-group> \
--docker-custom-image-name ghcr.io/altcha-org/sentinel:<previous-version>
  • Always test upgrades in a staging environment first
  • Database migrations are automatically applied during startup when needed
  • Allow 3-5 minutes for the upgrade to complete
