walinuxagent Updates

This document describes the process to update and test new versions of the walinuxagent package in SRUs.

The walinuxagent package is an Ubuntu distribution of the upstream Microsoft Azure Linux Agent that manages Linux provisioning, and VM interaction with the Azure Fabric Controller.

It provides the following functionality for Ubuntu cloud image deployments:

  • Image Provisioning.
  • Networking setup.
  • Kernel setup.
  • Diagnostics setup.
  • SCVMM Deployments
  • VM Extensions Management

For a more detailed list of functionality this package provides to Ubuntu cloud images, refer to the upstream project page at GitHub: https://github.com/Azure/WALinuxAgent

SRU Verification Process

This is the QA process that proposed walinuxagent packages are subjected to:

  • The new package candidate version is built in a PPA and tested on the target suite before being uploaded to the archive at all. This will involve one or both of:
    • Installing the PPA packages on an Azure VM, manually restoring the VM to a first boot state and rebooting it,
    • Generating a fresh image with the PPA package version preinstalled and testing that directly
  • Once the manual packaging tests pass successfully and the package requires no further changes, it will be uploaded to the archive.
  • Once accepted in to -proposed, a test image is built from -proposed, which is subjected to the full CPC image tests; this tests for more regressions across multiple Azure instance sizes. This includes tests for the following bugs:

Pre-SRU Test Cases

These are the test cases that all walinuxagent are subjected to before even getting to SRU: 

[Test case 1]: Upgrade testing
1.) Launch instance on Azure
2.) Upgrade walinuxagent (usually from PPA)
3.) Confirm that "waagent" is running, check /var/log/waagent.log for errors
4.) Reboot, repeat step 3
5.) Remove /var/lib/cloud and /var/lib/waagent (to simulate first boot conditions)
6.) Reboot, repeat step 3
7.) Repeat step 5, capture the instance as an image and provision a new instance from it; repeat step 3
  
[Test Case 2]: New instance
1.) Build new cloud image with PPA package
2.) Boot instance
3.) Confirm that instance provisioned

SRU Test Cases

These are automated tests: 

1.) Build new cloud image with -purposed package
2.) Boot instance
3.) Confirm that instance provisioned
4.) Run standard tests and regression tests
5.) Repeat from step 2 for all other Azure VM Sizes.
