Extension chaosazure¶

This project is a collection of actions and probes, gathered as an extension to the Chaos Toolkit. It targets the Microsoft Azure platform.

Install¶

This package requires Python 3.5+

To be used from your experiment, this package must be installed in the Python environment where chaostoolkit already lives.

$ pip install -U chaostoolkit-azure

Usage¶

To use the probes and actions from this package, add the following to your experiment file:

{
  "type": "action",
  "name": "start-service-factory-chaos",
  "provider": {
    "type": "python",
    "module": "chaosazure.vm.actions",
    "func": "stop_machines",
    "secrets": ["azure"],
    "arguments": {
      "parameters": {
        "TimeToRunInSeconds": 45
      }
    }
  }
}

That’s it!

Please explore the code to see existing probes and actions.

Configuration¶

This extension uses the Azure SDK libraries under the hood. The Azure SDK library expects that you have a tenant and client identifier, as well as a client secret and subscription, that allows you to authenticate with the Azure resource management API.

Configuration values for the Chaos Toolkit Extension for Azure can come from several sources:

• Experiment file
• Azure credential file

The extension will first try to load the configuration from the experiment file. If configuration is not provided in the experiment file, it will try to load it from the Azure credential file.

Credentials¶

Environment Variables¶

You can pass credentials via the following environment variables:

• AZURE_CLIENT_ID
• AZURE_CLIENT_SECRET
• AZURE_TENANT_ID

Or:

• AZURE_CLIENT_ID
• AZURE_ACCESS_TOKEN

Experiment Secrets¶

You may also pass them via the secrets block of the experiment:

{
  "secrets": {
    "azure": {
      "client_id": "your-super-secret-client-id",
      "client_secret": "your-even-more-super-secret-client-secret",
      "tenant_id": "your-tenant-id"
    }
  }
}

You can retrieve secretes as well from environment or HashiCorp vault.

If you are not working with Public Global Azure, e.g. China Cloud You can set the cloud environment.

{
  "client_id": "your-super-secret-client-id",
  "client_secret": "your-even-more-super-secret-client-secret",
  "tenant_id": "your-tenant-id",
  "cloud": "AZURE_CHINA_CLOUD"
}

Available cloud names:

• AZURE_CHINA_CLOUD
• AZURE_GERMAN_CLOUD
• AZURE_PUBLIC_CLOUD
• AZURE_US_GOV_CLOUD

Either of these values can be passed via AZURE_CLOUD as well.

Azure Credential File¶

You may also pass them via the Azure credential file:

You can retrieve a credentials file with your subscription ID already in place by signing in to Azure using the az login command followed by the az ad sp create-for-rbac command

az login
az ad sp create-for-rbac --sdk-auth > credentials.json

credentials.json:

{
  "subscriptionId": "<azure_aubscription_id>",
  "tenantId": "<tenant_id>",
  "clientId": "<application_id>",
  "clientSecret": "<application_secret>",
  "activeDirectoryEndpointUrl": "https://login.microsoftonline.com",
  "resourceManagerEndpointUrl": "https://management.azure.com/",
  "activeDirectoryGraphResourceId": "https://graph.windows.net/",
  "sqlManagementEndpointUrl": "https://management.core.windows.net:8443/",
  "galleryEndpointUrl": "https://gallery.azure.com/",
  "managementEndpointUrl": "https://management.core.windows.net/"
}

Store the path to the file in an environment variable called AZURE_AUTH_LOCATION and make sure that your experiment does NOT contain secrets section.

Subscription¶

Additionally you need to provide the Azure subscription id.

• As an environment variable

• AZURE_SUBSCRIPTION_ID

• Subscription id in the experiment file

{
  "configuration": {
    "azure_subscription_id": "your-azure-subscription-id"
  }
}

Configuration may be as well retrieved from an environment.

An old, but deprecated way of doing it was as follows, this still works but should not be favoured over the previous approaches as it’s not the Chaos Toolkit way to pass structured configurations.

{
  "configuration": {
    "azure": {
      "subscription_id": "your-azure-subscription-id"
    }
  }
}

• Subscription id in the Azure credential file

Credential file described in the previous “Credential” section contains as well subscription id. If AZURE_AUTH_LOCATION is set and subscription id is NOT set in the experiment definition, extension will try to load it from the credential file.

Putting it all together¶

Here is a full example for an experiment containing secrets and configuration:

Contribute¶

If you wish to contribute more functions to this package, you are more than welcome to do so. Please, fork this project, make your changes following the usual PEP 8 code style, sprinkling with tests and submit a PR for review.

The Chaos Toolkit projects require all contributors must sign a Developer Certificate of Origin on each commit they would like to merge into the master branch of the repository. Please, make sure you can abide by the rules of the DCO before submitting a PR.

Develop¶

If you wish to develop on this project, make sure to install the development dependencies. But first, create a virtual environment and then install those dependencies.

$ pip install -r requirements-dev.txt -r requirements.txt

Then, point your environment to this directory:

$ python setup.py develop

Now, you can edit the files and they will be automatically be seen by your environment, even when running from the chaos command locally.

Test¶

To run the tests for the project execute the following:

$ pytest

postgresql_flexible¶

count_servers¶

Return count of Azure servers.

– filter : str Filter the servers. If the filter is omitted all servers in the subscription will be selected for the probe. Filtering example: ‘where resourceGroup==”myresourcegroup” and name=”myresourcename”’

Signature:

def count_servers(filter: str = None,
                  configuration: Dict[str, Dict[str, str]] = None,
                  secrets: Dict[str, Dict[str, str]] = None) -> int:
    pass

Arguments:

Usage:

  "name": "count-servers",
  "type": "probe",
  "provider": {
    "type": "python",

  }
}

name: count-servers
provider:

  type: python
type: probe

create_databases¶

Delete databases at random.

Be aware: Deleting a database is an invasive action. You will not be able to recover the database once you deleted it.

– filter : str, optional Filter the servers. If the filter is omitted all databases of all servers in the subscription will be selected as potential chaos candidates.

name : str, required The name of the database to create.

Some calling examples. Deep dive into the filter syntax: https://docs.microsoft.com/en-us/azure/kusto/query/

create_databases(“where resourceGroup==’rg’“, ‘chaos-test’, c, s) Creating database named ‘chaos-test’ in all servers from the group ‘rg’

delete_databases¶

Delete databases at random.

Be aware: Deleting a database is an invasive action. You will not be able to recover the database once you deleted it.

Some calling examples. Deep dive into the filter syntax: https://docs.microsoft.com/en-us/azure/kusto/query/

delete_databases(“where resourceGroup==’rg’“, ‘chaos-’, c, s) Delete all database named ‘chaos-’ in all servers from the group ‘rg’

delete_tables¶

Delete a table randomly from all databases in servers matching the filter. Could be used to introduce random failures for resilience testing.

– filter : str, optional Filter the servers. If the filter is omitted, all servers in the subscription will be considered for potential table deletion. table_name : str, optional Specific table name to delete. If this is omitted, a table will be selected randomly for deletion. database_name : str, optional Specific database name to delete the table from.

Here are some examples of calling delete_tables.

delete_tables(“where resourceGroup==’rg’“, “users”, “mydatabase”, c, s, “https://myvault.vault.azure.net/”) Deletes the table ‘users’ from the database ‘mydatabase’ in all servers in the resource group ‘rg’

delete_tables(“where resourceGroup==’rg’ and name=’name’“, None, None, c, s, “https://myvault.vault.azure.net/”) Deletes a random table from a random database in the server named ‘name’ in the resource group ‘rg’

delete_tables(“where resourceGroup==’rg’ | sample 2”, “orders”, “mydatabase”, c, s, “https://myvault.vault.azure.net/”) Deletes the table ‘orders’ from the database ‘mydatabase’ in two random servers in the resource group ‘rg’
