GitHub Actions workflows (CI/CD)

To deploy the Azure TRE using GitHub workflows, create a fork of the repository.

Deployment is done using the /.github/workflows/deploy_tre.yml workflow. This method is also used to deploy the dev/test environment for the original Azure TRE repository.

Setup instructions

Before you can run the deploy_tre.yml workflow there are some one-time configuration steps that we need to do, similar to the Pre-deployment steps for manual deployment.

Tip

In some of the steps below, you are asked to configure repository secrets. Follow the GitHub guide on creating repository secrets if you are unfamiliar with this step.

Create a service principal for the subscription so that the workflow can provision Azure resources.
Decide on a TRE ID and the location for the Azure resources
Create app registrations for API authentication
Create app registrations and a user for the E2E tests
Create a workspace app registration for setting up workspaces (for the E2E tests)
Create a Teams WebHook for deployment notifications
Configure repository secrets
Deploy the TRE using the workflow

Create a service principal for provisioning resources

Login to Azure

Log in to Azure using az login and select the Azure subscription you wish to deploy Azure TRE to:
```
az login
az account list
az account set --subscription <subscription ID>
```
See Sign in with Azure CLI for more details.
Create a service principal

A service principal needs to be created to authorize CI/CD workflows to provision resources for the TRE workspaces and workspace services.

Create a main service principal with "Owner" role:
```
az ad sp create-for-rbac --name "sp-aztre-cicd" --role Owner --scopes /subscriptions/<subscription_id> --sdk-auth
```
Caution

Save the JSON output locally - as you will need it later for setting secrets in the build
Create a repository secret named AZURE_CREDENTIALS and use the JSON output from the previous step as its value. Note it should look similar to this:
```
{
  "clientId": "",
  "clientSecret": "",
  "subscriptionId": "",
  "tenantId": ""
}
```

Decide on a TRE ID and Azure resources location

Configure the TRE ID and LOCATION repository secrets

Secret name	Description
`TRE_ID`	A globally unique identifier. `TRE_ID` can be found in the resource names of the Azure TRE instance; for example, a `TRE_ID` of `tre-dev-42` will result in a resource group name for Azure TRE instance of `rg-tre-dev-42`. This must be less than 12 characters. Allowed characters: Alphanumeric and underscores.
`LOCATION`	The Azure location (region) for all resources. E.g. `westeurope`

Create app registrations for API authentication

Follow the instructions to run the app registration script in the Authentication and Authorization document. Use the values for TRE ID and LOCATION from above.

Configure the TRE API and Swagger UI repository secrets

Secret name	Description
`AAD_TENANT_ID`	The tenant ID of the Azure AD.
`SWAGGER_UI_CLIENT_ID`	The application (client) ID of the TRE Swagger UI app.
`API_CLIENT_ID`	The application (client) ID of the TRE API app.
`API_CLIENT_SECRET`	The application password (client secret) of the TRE API app.

Create an app registration and a user for the E2E tests

Follow the instructions to create an app registration and a test user for the E2E tests in the Authentication and Authorization document.

Configure the E2E Test repository secrets

Secret name	Description
`TEST_APP_ID`	The application (client) ID of the E2E Test app
`TEST_USER_NAME`	The username of the E2E Test User
`TEST_USER_PASSWORD`	The password of the E2E Test User

Create a workspace app registration for setting up workspaces (for the E2E tests)

Follow the instructions to create a workspace app registration (used for the E2E tests) - and make the E2E test user a WorkspaceOwner for the app registration.

Configure the TEST_WORKSPACE_APP_ID repository secret

Secret name	Description
`TEST_WORKSPACE_APP_ID`	The application (client) ID of the Workspaces app.
`TEST_WORKSPACE_APP_SECRET`	The application (client) secret of the Workspaces app.

Create a Teams Webhook for deployment notifications

The deploy_tre.yml workflow sends a notification to a Microsoft Teams channel when it finishes running.

Note

If you don't want to notify a channel, you can also remove the Notify dedicated teams channel steps in the workflow

Follow the Microsoft Docs to create a webhook for your channel
Configure the MS_TEAMS_WEBHOOK_URI repository secret

Secret name
Description

MS_TEAMS_WEBHOOK_URI URI for the Teams channel webhook

Configure repository/environment secrets

Configure additional secrets used in the deployment workflow:

Secret name	Description
`TRE_ID`	A globally unique identifier. `TRE_ID` can be found in the resource names of the Azure TRE instance; for example, a `TRE_ID` of `tre-dev-42` will result in a resource group name for Azure TRE instance of `rg-tre-dev-42`. This must be less than 12 characters. Allowed characters: Alphanumeric, underscores, and hyphens.
`MGMT_RESOURCE_GROUP_NAME`	The name of the shared resource group for all Azure TRE core resources.
`MGMT_STORAGE_ACCOUNT_NAME`	The name of the storage account to hold the Terraform state and other deployment artifacts. E.g. `mystorageaccount`.
`ACR_NAME`	A globally unique name for the Azure Container Registry (ACR) that will be created to store deployment images.

Configure repository/environment variables

Configure variables used in the deployment workflow:

Variable name	Description
`LOCATION`	The Azure location (region) for all resources. E.g. `westeurope`
`TERRAFORM_STATE_CONTAINER_NAME`	Optional. The name of the blob container to hold the Terraform state. Default value is `tfstate`.
`CORE_ADDRESS_SPACE`	Optional. The address space for the Azure TRE core virtual network. Default value is `10.0.0.0/22`.
`TRE_ADDRESS_SPACE`	Optional. The address space for the whole TRE environment virtual network where workspaces networks will be created (can include the core network as well). Default value is `10.0.0.0/16`
`AZURE_ENVIRONMENT`	Optional. The name of the Azure environment. Supported values are `AzureCloud` and `AzureUSGovernment`. Default value is `AzureCloud`.
`CORE_APP_SERVICE_PLAN_SKU`	Optional. The SKU used for AppService plan for core infrastructure. Default value is `P1v2`.
`WORKSPACE_APP_SERVICE_PLAN_SKU`	Optional. The SKU used for AppService plan used in E2E tests. Default value is `P1v2`.
`RESOURCE_PROCESSOR_NUMBER_PROCESSES_PER_INSTANCE`	Optional. The number of processes to instantiate when the Resource Processor starts. Equates to the number of parallel deployment operations possible in your TRE. Defaults to `5`.
`ENABLE_SWAGGER`	Optional. Determines whether the Swagger interface for the API will be available. Default value is `false`.

Deploy the TRE using the workflow

With all the repository secrets set, you can trigger a workflow run by pushing to develop/main of your fork, or by dispatching the workflow manually.
