Introduction

AzOps Resource Deletion performs deletion of locks, policyAssignments, policyDefinitions, policyExemptions, policySetDefinitions and roleAssignments in Azure, based on AzOps - Pull generated templates at all Azure scope levels (Management Group/Subscription/Resource Group).

• For any other resource type deletion is not supported by AzOps at this time.

By removing a AzOps generated file of a supported resource type AzOps removes the corresponding resource in Azure.

Please Note

• SPN used for deletion/change action, requires below actions in its role definition. Choose which combination best suites your implementation.

    Microsoft.Authorization/* OR  * (For everything)

• For Azure Locks removal

    Microsoft.Authorization/locks/delete
                            OR
    Microsoft.Authorization/locks/*

• For Azure Policy Assignment removal

    Microsoft.Authorization/policyAssignments/delete
                            OR
    Microsoft.Authorization/policyAssignments/*

• For Azure Policy Definition removal

    Microsoft.Authorization/policyDefinitions/delete
                            OR
    Microsoft.Authorization/policyDefinitions/*

• For Azure Policy Exemption removal

    Microsoft.Authorization/policyExemptions/delete
                            OR
    Microsoft.Authorization/policyExemptions/*

• For Azure Policy SetDefinition removal

    Microsoft.Authorization/policySetDefinitions/delete
                            OR
    Microsoft.Authorization/policySetDefinitions/*

• For Azure Role Assignment removal

    Microsoft.Authorization/roleAssignments/delete
                            OR
    Microsoft.Authorization/roleAssignments/*

Deletion dependency validation

When deletion of a supported object is sent to AzOps it evaluates to ensure resource dependencies are included in the deletion job. If a dependency is missing the module will throw (exit with error) and post the result of missing dependencies to the pull request conversation asking you to add it and try again.

Please Note: For the validation pipeline to fail in the manner intended (applicable to implementations created prior to AzOps release v1.9.0)

Ensure the results job "if" logic exists in your validate.yml

- name: "Results"
    if: always()
    shell: bash

Deletion dependency validation scenario

Scenario: Deletion of a policy definition and policy assignment where the assignment is referencing the policy definition.

• Create branch
  • Delete policy definition file from branch.
• Create pull request
  • Validation pipeline evaluates input and discovers there is a policy assignment with dependency towards the definition and the assignment is not part of the pull request.
  • Validation pipelines throws and posts results back to pull request conversation for user remediation.
• Two options:
  • a) In the branch delete the dependent file corresponding to the resulting error.
  • b) Delete the dependency in Azure and re-run validation.

Integration with AzOps Accelerator

The AzOps Accelerator pipelines (including Git Hub Actions & Azure Pipelines) incorporates the execution of resource deletion.

Conditional logic has been implemented to call Invoke-AzOpsPush with required change set in case of resource deletion operation, while existing logic without resource deletion remains same.

How to Add AzOps Resource Deletion to existing AzOps Push and Validate pipelines

Applicable to implementations created prior to AzOps release v1.6.0

1. Update the AzOps - Push pipeline by copying content from the latest upstream push.yml file into your existing file.
2. Update the AzOps - Validate pipeline by copying content from the latest upstream validate.yml file into your existing file.
