Region specific workers
The SecOps team at Car Rental have implemented the policy that when a deployment occurs, the infrastructure used must reside within the same region datacenter. Database deployments for Car Rental are handled by workers, so the deployment process needs to automatically select the correct worker during a deployment.
Region worker pools
To accommodate the policy, Car Rental has created distinct worker pools for each Azure region and created a worker for each.
Worker pool variable
Region specific worker pools are only half of the equation, the deployment still needs to be configured to select the correct pool based on the tenant being deployed to. To solve this issue, we'll utilize a worker pool variable. A worker pool variable is a type of variable that you can add to your project. Just like other variables, these variables can be scoped to tenant tags
Configure step to use worker pool variable
The Flyway step of the Car Rental deployment process is configured to run on a worker and utilize the Project.Worker.Pool variable
Because the tenants for the Car Rental application have been assigned their appropriate Azure Region tag, Octopus Deploy automatically selects the correct worker when performing a deployment to the tenant. The De Moines tenant is assigned the Central US Azure Region tag, below is the worker selected during the deployment for De Moines and the members of the Azure Cental US worker pool
