Runbook Reference

What is a runbook

In simple terms:

The **runbook** contains all the configurations of LISA operation. It keeps you from lengthy command-line commands and makes it easy to adjust configurations.

See Runbook for further knowledge.

How-to

Configure Azure deployment

Below section is for running cases on Azure platform, it specifies:

  • admin_private_key_file: the private key file to access the Azure VM.

  • subscription_id: Azure VM is created under this subscription.

platform:
  - type: azure
    admin_private_key_file: $(admin_private_key_file)
    azure:
      subscription_id: $(subscription_id)

Select and set test cases

Below section is to specify P0 and P1 test cases excluding case with name hello.

testcase:
  - criteria:
      priority: [0, 1]
  - criteria:
      name: hello
    select_action: exclude

Use variable and secrets

Below section is to specify the variable in name/value format. We can use this variable in other field in this format $(location).

variable:
  - name: location
    value: westus2

The value of variable passed from command line will override the value in runbook yaml file.

lisa -r sample.yml -v "location:eastus2"

Below section is to specify the path of yaml file which stores the secret values.

variable:
  - file: secret.yml

Content of secret.yml.

subscription_id:
  value: replace_your_subscription_id_here
  is_secret: true
  mask: guid

Use partial runbook

Below three yaml files will be loaded in this sequence.

loading runbook sample.yml
|-- loading include tier.yml
|   |-- loading include t0.yml

The variable values in the included yaml file(s) will be overridden by the including yaml file(s). The relative path is always relative to the including yaml file.

Part of sample.yml

include:
  - path: ./tier.yml

Part of tier.yml.

include:
  - path: ./t$(tier).yml
variable:
  - name: tier
    value: 0

Part of t0.yml.

testcase:
  - criteria:
      priority: 0

Use extensions

Below section is to specify path of extensions, the extensions are modules for test cases or extended features.

extension:
  - name: extended_features
    path: ../../extensions
  - ../../lisa/microsoft/testsuites/core

Use transformers

Transformers are executed one by one. The order is decided by their dependencies. If there is no dependencies, their order in runbook affects the execution order.

Below transformer shows how to deploy a VM in Azure, and export it to a VHD. Before the exporting, other transformers can be added, like install kernel.

transformer:
- type: azure_deploy
  requirement:
    azure:
      marketplace: redhat rhel 7_9 7.9.2021051701
- type: azure_vhd
  resource_group_name: $(azure_deploy_resource_group_name)
  rename:
    azure_vhd_url: vhd
- type: azure_delete
  resource_group_name: $(azure_deploy_resource_group_name)

Below is the transformer to build kernel from source code and patches.

transformer:
- type: azure_deploy
  requirement:
    azure:
      marketplace: $(marketplace_image)
    core_count: 16
  enabled: true
- type: kernel_installer
  connection:
    address: $(azure_deploy_address)
    private_key_file: $(admin_private_key_file)
  installer:
    type: source
    location:
      type: repo
      path: /mnt/code
      ref: tags/v4.9.184
    modifier:
      - type: patch
        repo: https://github.com/microsoft/azure-linux-kernel.git
        file_pattern: Patches_Following_Mainline_History/4.9.184/*.patch

Reference

name

type: str, optional, default is “not_named”

Part of the test run name. This name will be used to group results and put it in title of the html report, also the created resources’ name contains this specified str.

name: Azure Default

test_project

type: str, optional, default is empty

The project name of this test run. This name will be used to group test results in html, it also shows up in notifier message.

test_project: Azure Image Weekly Testing

test_pass

type: str, optional, default is empty

The test pass name of this test run. This name combined with test project name will be used to group test results in html report, it also shows up in notifier message.

test_pass: bvt testing

tags

type: list of str, optional, default is empty

The tags of the test run. This name combined with test project name and test pass name will be used to group test results in html report, it also shows up in notifier message.

tags:
  - test
  - bvt

concurrency

type: int, optional, default is 1.

The number of concurrent running environments.

include

type: list of path, optional, default is empty

Share runbook parts for similar runs, including the shared content via that yaml primitive.

path

It can be absolute or relative path of current runbook.

extension

type: list of path str or name/path pairs, optional, default: empty

The path and the name of the modules, we can also just specify the extension path directly.

extension:
  - name: ms
    path: ../../extensions

name

type: str, optional, default is empty

Each extension can be specified a name. With the name, one extension can reference another one, using above example extension, in code we can reference it like this way ms.submodule.

path

type: str, optional, default is empty

Path of extension, it can be absolute or relative path of current runbook file.

variable

type: list of path str or name/value pairs, optional, default: empty

Used to support variables in other fields.

The values pass from command line has the highest priority, with below example, any places use ${subscription_id} will be replaced with value subscription id B.

lisa -r ./microsoft/runbook/azure.yml -v "subscription_id:<subscription id A>"
variable:
  - name: subscription_id
    value: subscription id B

The variable values in the runbook have higher priority than the same variables defined in any included runbook file. Thus, ${location} will be replaced with value northeurope in the following example.

include:
  - path: tier.yml
variable:
  - name: location
    value: northeurope

tier.yml

variable:
  - name: location
    value: westus2

The later defined variables values in runbook have higher priority than the same variables previous defined. ${location} will be replaced with value northeurope.

variable:
  - name: location
    value: westus2
  - name: location
    value: northeurope

is_secret

type: bool, optional, default is False.

When set to True, the value of this variable will be masked in log and other output information.

Recommend to use secret file or env variable. It’s not recommended to specify secret value in runbook directly.

file

type: list of str, optional, default: empty

Specify path of other yml files which define variables.

name

type: str, optional, default is empty.

Variable name.

value

prefix

type: str, optional, default is the name.

The prefix of generated variables from this transformer. If it’s not specified, it will use the name field.

depends_on

type: list of str, optional, default is None.

rename

type: Dict[str, str], optional, default is None.

The variables, which need to be renamed. If the variable exists already, its value will be overwritten by the transformer. For example, ["to_list_image", "image"] means change the variable name to_list_image to image. The original variable name must exist in the output variables of the transformer.
