The goal of this template is to provide an automated way of provisioning an infrastructure to handle Dockerized applications.
Right now this template works with the following Azure resources:
- Container Registry
- App Service
- App Service Plan
- Application Insights
Make sure that you have Terraform and Azure CLI installed on your system.
If you're a Mac user, you can install Terraform by using Homebrew command brew install terraform.
Once Terraform is installed, run terraform version to verify installation.
Note. The template expects that you already have an existing resource group in Azure.
Next step is to rename terraform.tfvars.example file to be terraform.tfvars. This file contains a list of credentials you need to configure before using the template.
| Value | Description |
|---|---|
| subscription_id | Corresponds to id field from az account list command. |
| tenant_id | Corresponds to tenantId field from az account list command. |
| resource_group | Azure resource group where resources will be provisioned. |
| acr_name | Name for your Container Registry resource. |
| app_insights_name | Name for your Application Insights resource. |
| app_service_name | Name for your App Service resource. |
| app_service_plan_name | Name for your App Service Plan resource. |
Once you completed all the steps above, you're ready to provision your Azure cloud infrastructure.
First, run terraform init to initialize a Terraform working directory. Then run terraform plan to generate and see an execution plan for your resources.
Running terraform apply will build the specified infrastructure.
To destroy Terraform-managed infrastructure, run terraform destroy.
When your infrastructure is provisioned, run terraform output to see a list of values / credentials you can supply to your application or service.
| Value | Description |
|---|---|
| acr_admin_username | Username to access Container Registry where you host your Docker images. |
| acr_admin_password | Password to access Container Registry where you host your Docker images. |
| app_insights_instrumentation_key | Instrumentation key from Application Insights to be used in your app during logging etc. This values is also exposed as environment variable in App Service with name APP_INSIGHTS_INSTRUMENTATION_KEY. |
| app_service_hostname | Hostname for your App Service application. |
| app_service_outbound_ip_addresses | A comma separated list of outbound App Service IP addresses |
- Move Terraform state to remote location (e.g. Azure Blob Storage)
- Enable support for multiple environments (Terraform workspaces?)
- Provision Azure Container Instances service (as an alternative to App Service)
- Provide option to create resource group (if none exists)
