Declarative IaC is more efficient and reliable, since you do not need to know what state the infrastructure is currently in when you write the IaC code, and the tooling will figure out what changes / updates to make when deployed. The following blog post depicts how you need to create a server application, update its manifest, create and assign a client application to be able to set RBAC up correctly: A secret is anything that you want to tightly control access to, such as API keys, passwords, or certificates.

Deploying to Azure using Terraform and Github (actions), has never been easier. Terraform Website; AzureAD Provider Documentation; AzureAD Provider Usage Examples; Slack Workspace for Contributors (Request Invite); Usage Example Terraform for Java developers, part (4/4) In this fourth video, we complete our Terraform configuration and add a Java application service, configure our Spring Boot project to be deployed on Azure, run everything in the cloud, and finish by destroying our infrastructure. This will always be the first command you run after writing new Terraform configuration files, or even cloning existing files from a source control repository. You can setup your process to use either a Client Secret or Client Certificate as means of authenticating with the Azure AD Service Principal identity. To authenticate with Azure and set the login context to your desired Azure Subscription, use the following Azure CLI commands: Once you have used the Azure CLI to login and set the context to your desired Azure Subscription, you can then start running Terraform deployments against that Azure Subscription.

There is full ARM support in terraform if you have an existing library of templates to start from. provider "azuread" { version = "=0.3.0" subscription_id = "There is no subscription in the B2C directory, so you can use the tenant id as subscription id." If you are needing to automate the deployment and configuration of infrastructure within multiple environments or may want to move to a different environment later, then using platform specific IaC tooling would require you to write completely different code for each platform.
