Add GRPC Reflection Service to Enhance Dynamic Discovery

Lukaasko commented 4 months ago

Overview

This pull request introduces a new GRPC reflection service to the plgd-dev/hub project, enhancing the system's ability to dynamically discover GRPC services and methods. This is particularly useful for developers and tools that need to interact with GRPC services without prior knowledge of their interfaces.

Key Features:

Service Implementation:

A dedicated GRPC reflection service is implemented, allowing clients to query available GRPC services and their methods dynamically.
The service is built using a multi-stage Dockerfile to optimize the build process and final image size.

Configuration and Deployment:

A new configuration file (grpc-reflection.yaml) is introduced, detailing service-specific settings such as logging levels and GRPC addresses.
Kubernetes deployment configurations are added, including Helm chart updates to manage the service's lifecycle within a Kubernetes cluster.

Integration with Existing Infrastructure:

The service is integrated into the existing build and deployment pipelines, ensuring seamless operation alongside other services.
Environment variables and configuration options are provided to customize the service's behavior and integration points.

This addition significantly enhances the plgd-dev/hub's capabilities, providing a robust solution for GRPC service discovery and interaction.

Tips

### Chat There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai): - Review comments: Directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit .` - `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 generate interesting stats about this repository and render them as a table.` - `@coderabbitai show all the console.log statements in this repository.` - `@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. ### CodeRabbit Commands (invoked as PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai full review` to do a full review from scratch and review all the files again. - `@coderabbitai summary` to regenerate the summary of the PR. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository. - `@coderabbitai help` to get help. Additionally, you can add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. ### CodeRabbit Configuration File (`.coderabbit.yaml`) - You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository. - Please see the [configuration documentation](https://docs.coderabbit.ai/guides/configure-coderabbit) for more information. - If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json` ### Documentation and Community - Visit our [Documentation](https://coderabbit.ai/docs) for detailed information on how to use CodeRabbit. - Join our [Discord Community](https://discord.com/invite/GsXnASn26c) to get help, request features, and share feedback. - Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.

@jkralik: Here's a draft for the pull request description:

Pull Request Description

This pull request introduces improvements to the validation logic within the hub's services, focusing on both JWT and GRPC components.

Key Changes:

JWT Validator Enhancement:
- Added a check in the JWT validator to ensure that endpoints are configured. If no endpoints are specified, an error is returned. This change enhances the robustness of the JWT validation process by preventing the initialization of validators without endpoints.
GRPC Service Adjustment:
- Removed a redundant GRPC authorization configuration validation call in the snippet service. This change might reflect a refactoring of the validation logic to streamline the service initialization process.

These changes aim to enhance the reliability and maintainability of the hub's security and service layers, ensuring that configurations are correctly validated and reducing potential runtime errors.

Feel free to modify or expand upon this draft as needed.
