Azure Data Factory provides Windows container support for the Self-Hosted Integration Runtime. You can download the Docker Build source code and combine the building and running process in your own continuous delivery pipeline.

Tip

This article explains how to run the Self-Hosted Integration Runtime in a Windows container on a compatible physical or virtual machine. If you don't want to manage infrastructure, you can run the Self-Hosted Integration Runtime on Azure App Service. For more information, see the Azure Data Factory self-hosted integration runtime on App Service sample.

Prerequisites

Get started

  1. Install Docker and enable Windows containers.

  2. Download the container image source code from GitHub.

  3. If you need to use a specific version of the SHIR, you can download it and move it to the SHIR folder.

    Otherwise, skip this step. The container image build process downloads the latest version of the SHIR automatically.

  4. Open your folder in the shell:

    cd "yourFolderPath"

  5. Build the Windows container image:

    docker build . -t "yourDockerImageName" 

  6. Run the container with specific arguments by passing environment variables:

     docker run -d -e AUTH_KEY=<ir-authentication-key> \
 [-e NODE_NAME=<ir-node-name>] \
 [-e ENABLE_HA={true|false}] \
 [-e HA_PORT=<port>] \
 [-e ENABLE_AE={true|false}] \
 [-e AE_TIME=<expiration-time-in-seconds>] \
 <yourDockerImageName>  
Name Necessity Default Description
AUTH_KEY Required The authentication key for the self-hosted integration runtime.
NODE_NAME Optional hostname The specified name of the node.
ENABLE_HA Optional false The flag to enable high availability and scalability.
It supports up to 4 nodes registered to the same IR when HA is enabled, otherwise only 1 is allowed.
HA_PORT Optional 8060 The port to set up a high availability cluster.
ENABLE_AE Optional false The flag to enable offline nodes auto-expiration.
If enabled, the expired nodes are removed automatically from the IR when a new node is attempting to register.
Only works when ENABLE_HA=true.
AE_TIME Optional 600 The expiration time out duration for offline nodes in seconds.
Should be no less than 600 (10 minutes).

Container health check

After the 120-second startup period, the health check runs periodically every 30 seconds. It provides the SHIR's health status to the container engine.

Limitations

Currently we don't support the below features when running the Self-Hosted Integration Runtime in Windows containers:

  • HTTP proxy
  • Encrypted node-node communication with TLS/SSL certificate
  • Generate and import backup
  • Daemon service
  • Auto-update

There's a known issue when hosting an Azure Data Factory self-hosted integration runtime in Azure App Service, where a restart creates a new container instead of reusing the existing one. This causes configuration settings, such as concurrency adjustments, to be lost, changes to the host file for FQDN-to-IP mapping to reset, and the node name to change.
