if you might need to map services around CDN or firewall services to simplify that WAF since your chart may not have an original ip that can be easily defined.

Walkthrough

The pull request introduces a new configuration option hostAliases to the n8n Helm chart, enabling custom host alias mappings across multiple Kubernetes deployment configurations. This feature allows users to define specific hostname-to-IP address mappings for pods. Additionally, the deployment strategy has been explicitly set to "Recreate" mode, which changes how pods are updated during deployments. These changes provide more flexibility in network configuration and clarify the deployment behavior.

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

Documentation and version updates required for hostAliases feature

Please update:

  • Add hostAliases feature documentation to README.md explaining its purpose and configuration
  • Bump chart version from 0.25.2 to 0.26.0 (minor version for new feature)
  • Add changelog entry in Chart.yaml for the hostAliases feature under artifacthub.io/changes
🔗 Analysis chain

Line range hint 149-153: Verify documentation and version updates.

Please ensure:

  1. The README.md or CHANGELOG.md is updated to document the new hostAliases feature
  2. The chart version is bumped according to semver (minor version for new feature)
🏁 Scripts executed

The following scripts were executed for the analysis:

🧹 Nitpick comments (1)
charts/n8n/templates/deployment.worker.yaml (1)

104-107: LGTM! Consistent implementation across all deployments.

The hostAliases configuration is consistently implemented across all deployment types (main, webhook, and worker).

Consider adding a comment in the values.yaml documentation explaining that hostAliases will be applied to all deployment types (main, webhook, and worker pods) when configured.

149-153: LGTM! Well-documented hostAliases configuration.

The implementation follows the Kubernetes specification for hostAliases, and the example clearly demonstrates the expected format.


Line range hint 158-162: Verify the impact of changing deployment strategy to "Recreate".

Changing from RollingUpdate to Recreate means pods will be stopped before new ones are created, which could lead to downtime during updates. Ensure this aligns with the application's requirements.

Consider if RollingUpdate might be more appropriate for maintaining availability during updates, unless there are specific reasons requiring Recreate (e.g., stateful requirements, database migrations).

125-128: LGTM! Correct implementation of hostAliases.

The hostAliases configuration is properly implemented in the pod spec with correct indentation and conditional inclusion.

charts/n8n/templates/deployment.webhooks.yaml (1)

104-107: LGTM! Consistent implementation across deployments.

The hostAliases configuration matches the implementation in the main deployment.
