Introduction

We’re pleased to announce the release of authzgcpk8stokeninjector v0.2.0, available now on GitHub. Released on January 26, 2025, this update brings an important structural improvement that makes the project properly consumable as a Go module dependency.

For users familiar with authzgcpk8stokeninjector—the gRPC ExtAuthz service that injects GCP identity tokens into Envoy Proxy requests in Kubernetes environments—this release ensures the project is now correctly structured for versioning and import within the Go ecosystem.

What’s New

Proper Go Module Path

The primary change in v0.2.0 is the update of the Go module path from an incomplete local declaration to the full GitHub repository structure: github.com/UnitVectorY-Labs/authzgcpk8stokeninjector. This correction enables:

  • Proper Go module resolution: The project can now be imported and versioned correctly within the Go dependency management system
  • Semantic import paths: Developers can now use standard Go import statements with full repository path specification
  • Better ecosystem integration: The module is now properly discoverable via pkg.go.dev and other Go tooling

New Contributor Welcome

This release marks the first contribution from @JaredHatfield, who submitted the pull request to correct the module path. Welcome to the project!

Why It Matters

For Container Users

If you’re using authzgcpk8stokeninjector as a Docker sidecar container in your Kubernetes deployments, this release is a seamless drop-in upgrade. No configuration changes are required—simply pull the updated image:

docker pull ghcr.io/unitvectory-labs/authzgcpk8stokeninjector:v0.2.0

For Go Module Consumers

For developers importing authzgcpk8stokeninjector as a Go module dependency, this fix is essential. Update your go.mod file:

require github.com/UnitVectorY-Labs/authzgcpk8stokeninjector v0.2.0

And update import statements throughout your codebase from:

  • authzgcpk8stokeninjector/internal/cache → github.com/UnitVectorY-Labs/authzgcpk8stokeninjector/internal/cache
  • authzgcpk8stokeninjector/internal/token → github.com/UnitVectorY-Labs/authzgcpk8stokeninjector/internal/token

This change makes proper Go module versioning and dependency management possible for the project.

Getting Started
