Summary

Follow-up to #12 addressing CodeRabbit review comments and adding Renovate tracking for k3s versions.

Changes

  • Guard groups['server'] lookup with groups.get('server', []) to produce a clear assert error instead of a hard-fail when the group is absent
  • Tighten negative hostname test to verify the specific IP validation error message, not just any playbook failure
  • Add Renovate annotations (# renovate: datasource=github-releases depName=k3s-io/k3s) to all inventory files with k3s_version
  • Add customManager regex rule to renovate.json for automatic k3s version tracking
  • Fix pre-existing managerFilePatternsfileMatch in all customManagers (Renovate 37 compatibility)

Test plan

  • ansible-lint passes
  • All existing tests pass (multi-master, single-master, explicit override, hostname rejection)
  • Renovate --platform=local correctly detects k3s updates across all 4 inventory files

Summary by CodeRabbit

  • Bug Fixes

    • Improved error handling when server group configuration is missing from deployment setup
  • Chores

    • Enhanced automated dependency tracking for k3s across example and test inventory files

… test

Use groups.get('server', []) to avoid hard-fail when the server group
is absent, producing a clearer error via the existing assert instead.

Tighten the negative CI test to verify the specific IP validation error
message rather than accepting any playbook failure as success.

Add Renovate annotations to all inventory files referencing k3s_version
and a customManager regex rule to detect and update them automatically
from k3s-io/k3s GitHub releases.

📝 Walkthrough

Walkthrough

This pull request enhances dependency tracking and error validation across the project. It renames a Renovate configuration field, adds k3s version tracking via Renovate metadata comments in inventory files, improves the test workflow's error validation logic, and adds defensive error handling to the Ansible task.

Changes

Cohort / File(s) Summary
Test Workflow Enhancement
.github/workflows/test.yml
Updates the "Test hostname host keys are rejected" step to capture Ansible output and validate specific error messages before marking success, rather than relying solely on exit status.
Renovate Configuration
renovate.json
Renames "managerFilePatterns" to "fileMatch" in three existing regex customManagers entries; adds new customManagers entry to track k3s_version from inventory files using regex pattern matching on Renovate metadata comments.
Inventory Renovate Annotations
examples/rhel/inventory.yml, examples/suse/inventory.yml, examples/ubuntu/inventory.yml, tests/ci-inventory.yml
Adds Renovate metadata comments documenting k3s GitHub Releases source for dependency tracking.
Ansible Task Robustness
roles/cozystack/tasks/compute-master-nodes.yml
Replaces direct dictionary access groups['server'] with safe .get() method to prevent KeyError when the 'server' group is absent.

Summary of Changes

Hello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the stability of the Ansible playbooks by making the server group lookup more resilient to missing data. Additionally, it introduces automated dependency management for k3s versions across various inventory files using Renovate, ensuring that the project stays up-to-date with the latest k3s releases. The Renovate configuration itself was also updated for compatibility with a newer version.

Highlights

  • Improved Robustness: Modified Ansible playbook logic to safely handle cases where the 'server' group might be absent, preventing hard failures.
  • Automated K3s Version Tracking: Integrated Renovate annotations into inventory files and configured renovate.json to automatically track and update k3s versions from GitHub releases.
  • Renovate Configuration Update: Updated Renovate custom manager configurations from managerFilePatterns to fileMatch for compatibility with Renovate 37.

Code Review

This pull request adds Renovate tracking for k3s versions and addresses feedback from a previous review. The changes are generally well-implemented, including updating the Renovate configuration for v37 compatibility and improving the robustness of an Ansible task. However, I've identified a potential issue in the new regex for k3s version tracking in renovate.json. The current regex could incorrectly match commented-out versions. I've provided a suggestion to make the regex more robust.

"customType": "regex",
"fileMatch": ["inventory\\.yml$", "ci-inventory\\.yml$"],
"matchStrings": [
"#\\s*renovate:\\s*datasource=(?<datasource>[^\\s]+)\\s+depName=(?<depName>[^\\s]+)[\\s\\S]*?k3s_version:\\s*(?<currentValue>[^\\s]+)"

The current regex for k3s_version is not anchored to the beginning of the line. This could cause it to incorrectly match a commented-out k3s_version line if one exists in the inventory file before the active one. This would lead Renovate to either fail or attempt to update the wrong line.

For example, in this scenario, the regex would incorrectly capture the commented-out version:

# renovate: datasource=github-releases depName=k3s-io/k3s
# k3s_version: v1.30.0+k3s1  # <-- old version, would be matched
k3s_version: v1.35.0+k3s3

To make the regex more robust, you should anchor the k3s_version match to the start of a line (using ^ in multiline mode).

        "#\s*renovate:\s*datasource=(?<datasource>[^\s]+)\s+depName=(?<depName>[^\s]+)[\s\S]*?^\s*k3s_version:\s*(?<currentValue>[^\s]+)"

The regex is anchored by the # renovate: annotation comment which acts as the match entry point. A commented-out k3s_version would only be caught if it had a # renovate: annotation directly above it, which would be intentional. The scenario you describe (annotation above a comment above the real value) is not a realistic pattern in our inventories. Keeping the regex simple is preferred over adding multiline anchoring complexity.
