Cloud Custodian - Azure Support

This a plugin to Cloud Custodian that adds Azure support.

Install Cloud Custodian and Azure Plugin

The Azure provider must be installed as a separate package in addition to c7n.

$ git clone https://github.com/cloud-custodian/cloud-custodian.git
$ virtualenv custodian
$ source custodian/bin/activate
(custodian) $ pip install -e cloud-custodian/.
(custodian) $ pip install -e cloud-custodian/tools/c7n_azure/.

Write your first policy

A policy specifies the following items:

The type of resource to run the policy against
Filters to narrow down the set of resources
Actions to take on the filtered set of resources

For this tutorial we will add a tag to all virtual machines with the name "Hello" and the value "World".

Create a file named custodian.yml with this content:

policies:
    - name: my-first-policy
      description: |
        Adds a tag to all virtual machines
      resource: azure.vm
      actions:
        - type: tag
          tag: Hello
          value: World

Run your policy

First, choose one of the supported authentication mechanisms and either log in to Azure CLI or set environment variables as documented in Authentication.

custodian run --output-dir=. custodian.yml

If successful, you should see output similar to the following on the command line

2016-12-20 08:35:06,133: custodian.policy:INFO Running policy my-first-policy resource: azure.vm
2016-12-20 08:35:07,514: custodian.policy:INFO policy: my-first-policy resource:azure.vm has count:1 time:1.38
2016-12-20 08:35:08,188: custodian.policy:INFO policy: my-first-policy action: tag: 1 execution_time: 0.67

You should also find a new my-first-policy directory with a log and other files (subsequent runs will append to the log by default rather than overwriting it).

Running Tests

If you'd like to help with the development of Azure support, you'll need uv installed. It provides a pip-compatible interface, & will handle all the dependencies needed for you.

You can then run the unit tests like this:

# Assuming you're in the `cloud-custodian` top-level directory...
$ cd tools/c7n_azure

$ uv run pytest tests_azure
