+A proxy service for Git webhooks that validates and forwards webhook events to an upstream URL.
 
-A proxy to let webhooks to reach a Jenkins instance running behind a firewall
+**Go Version:** 1.24.3
+**FIPS Support:** Yes (when built with `GOFIPS140='v1.0.0'`)
 
-## PROBLEM
+## Overview
 
-Jenkins is awesome and matchless tool for both CI & CD; but unfortunately its a gold mine if left in wild with wide open access; so, we always want to put it behind a firewall. But when we put it behind firewall then webhooks don't work anymore and no one wants the pull based polling but rather prefer the build to start as soon as there is a commit!
+Git Webhook Proxy is a lightweight service that sits between Git providers (GitHub, GitLab) and your internal services. It:
 
-## SOLUTION
+- Validates webhook signatures/tokens
+- Filters requests based on allowed paths
+- Filters requests based on users (ignored or allowed)
+- Forwards valid requests to an upstream URL
 
-This little proxy makes webhooks start working again!
+## Features
 
-### Supported Providers
+- Support for GitHub and GitLab webhooks
+- Webhook signature/token validation
+- Path-based filtering
+- User-based filtering
+- Health check endpoint
 
-Currently we support the following git providers out of the box:
+## Security Improvements
 
-* Github
-* Gitlab
+This version has been updated to use modern, well-maintained Go modules and includes FIPS 140-3 compliance:
 
-### Configuration
+- Replaced `github.com/julienschmidt/httprouter` with `github.com/go-chi/chi/v5`
+- Replaced `github.com/namsral/flag` with `github.com/spf13/pflag`
+- Added FIPS 140-3 compliant mode (when built with `GOFIPS140='v1.0.0'`)
+- Updated to Go 1.24.3
 
-GitWebhookProxy can be configured by providing the following arguments either via command line or via environment variables:
+These changes address security concerns related to using outdated or abandoned modules that might have unpatched CVEs and provide FIPS 140-3 compliance for environments that require it.
 
-| Parameter     | Description                                                                       | Default  | Example                                    |
-|---------------|-----------------------------------------------------------------------------------|----------|--------------------------------------------|

-### Vanilla Manifests
+### Environment Variables
 
-For Vanilla manifests, you can either first clone the respository or download the `deployments/kubernetes/gitwebhookproxy.yaml` file only.
+All command-line arguments can also be specified as environment variables with the `GWP_` prefix. For example:
 
-#### Configuring
-
-Below mentioned attributes in `gitwebhookproxy.yaml` have been hard coded to run in our cluster. Please make sure to update values of these according to your own configuration.
-
-1. Change below mentioned attribute's values in `Ingress` in `gitwebhookproxy.yaml`
-
-```yaml
- rules:
-  - host: gitwebhookproxy.example.com
 ```
-
-```yaml
-  tls:
-  - hosts:
-    - gitwebhookproxy.example.com
+GWP_LISTEN=:8080
+GWP_UPSTREAMURL=http://jenkins.example.com
+GWP_PROVIDER=github
+GWP_SECRET=your-webhook-secret
 ```
 
-2. Change below mentioned attribute's values in `Secret` in `gitwebhookproxy.yaml`
-
-```yaml
-data:
-  secret: example
-```
+### Example
 
-3. Change below mentioned attribute's values in `ConfigMap` in `gitwebhookproxy.yaml`
+```bash
+# Run with command-line arguments
+./gitwebhookproxy --listen=:8080 --upstreamURL=http://jenkins.example.com --provider=github --secret=your-webhook-secret
 
-```yaml
-data:
-  provider: github
-  upstreamURL: https://jenkins.example.com
-  allowedPaths: /github-webhook,/project
-  ignoredUsers: stakater-user
+# Run with environment variables
+export GWP_UPSTREAMURL=http://jenkins.example.com
+export GWP_SECRET=your-webhook-secret
+./gitwebhookproxy
 ```
 
-#### Deploying
-
-Then you can deploy GitwebhookProxy by running the following kubectl commands:
+### Docker
 
 ```bash
-kubectl apply -f gitwebhookproxy.yaml -n <namespace>
-```
-
-*Note:* Make sure to update the `port` in deployment.yaml as well as service.yaml if you change the default `listenAddress` port.
-
-### Helm Charts
-
-Alternatively if you have configured helm on your cluster, you can add gitwebhookproxy to helm from our public chart repository and deploy it via helm using below mentioned commands
-
-1. Add the chart repo:
-
-   i. `helm repo add stakater https://stakater.github.io/stakater-charts/`
-
-   ii. `helm repo update`
-2. Set configuration as discussed in the `Configuring` section
-
-   i. `helm fetch --untar stakater/gitwebhookproxy`
-
-   ii. Open and edit `gitwebhookproxy/values.yaml` in a text editor and update the values mentioned in `Configuring` section.
-
-3. Install the chart
-   * `helm install stakater/gitwebhookproxy -f gitwebhookproxy/values.yaml -n gitwebhookproxy`
-
-## Running outside Kubernetes
+# Standard run
+docker run -p 8080:8080 \
+  -e GWP_UPSTREAMURL=http://jenkins.example.com \
+  -e GWP_PROVIDER=github \
+  -e GWP_SECRET=your-webhook-secret \
+  stakater/gitwebhookproxy:latest
 
-### Run with Docker
 
-To run the docker container outside of Kubernetes, you can pass the configuration as the Container Entrypoint arguments.
-The docker image is available on docker hub. Example below:
+## Building from Source
 
-`docker run stakater/gitwebhookproxy:v0.2.63 -listen :8080 -upstreamURL google.com -provider github -secret "test"`
+### Standard Build
 
-### Run with Docker compose
-
-For docker compose, the syntax is a bit different
+```bash
+# Clone the repository
+git clone https://github.com/stakater/GitWebhookProxy.git
+cd GitWebhookProxy
 
-```yaml
-jenkinswebhookproxy: 
-    image: 'stakater/gitwebhookproxy:latest'
-    command: ["-listen", ":8080", "-secret", "test", "-upstreamURL", "jenkins.example.com, "-allowedPaths", "/github-webhook,/ghprbhook"]
-    restart: on-failure
-```
+# Build the binary
+go build -o gitwebhookproxy
 
-## Troubleshooting
-### 405 Method Not Allowed with Jenkins & github plugin
-If you get the following error when setting up webhooks for your jobs in Jenkins, make sure you have the trailing `/` in the webhook configured in Jenkins. 
+# Run the binary
+./gitwebhookproxy --upstreamURL=http://jenkins.example.com
 ```
-Error Redirecting '/github-webhook' to upstream', Upstream Redirect Status: 405 Method Not Allowed
-```

+# GitWebhookProxy Build System
+
+This document describes the build system for GitWebhookProxy, which now supports multi-architecture builds and alternative container engines.
+
+## Features
+
+- **Multi-architecture support**: Build for both `linux/amd64` and `linux/arm64` platforms
+- **Container engine flexibility**: Works with both Docker and Podman
+- **Modern Go tooling**: Uses Go modules and Go's native embed package for embedding static assets
+- **Efficient builds**: Uses multi-stage builds to minimize image size
+
+## Build Options
+
+### Basic Build
+
+To build the binary locally:
+
+```bash
+make build
+```
+
+### Container Build
+
+#### Multi-architecture Container (Recommended)
+
+Build a multi-architecture container image:
+
+```bash
+make container
+```
+
+This will:
+1. Create a manifest for the container image
+2. Build the image for each platform specified in `PLATFORMS` (default: linux/amd64 and linux/arm64)
+3. Push the manifest to the registry if `REGISTRY` is defined
+
+You can customize the build with these variables:
+
+- `PLATFORMS`: Space-separated list of platforms to build for (default: `linux/amd64 linux/arm64`)
+- `DOCKER_IMAGE`: Image name (default: `stakater/gitwebhookproxy`)
+- `DOCKER_TAG`: Image tag (default: `dev`)
+- `REGISTRY`: Registry to push to (default: `docker.io`)
+- `CONTAINER_CLI`: Container CLI to use (automatically detected, defaults to `docker` if `podman` is not available)
+
+Example:
+
+```bash
+# Build for specific platforms
+PLATFORMS="linux/amd64 linux/arm64 linux/ppc64le" make container
+
+# Use a specific container engine
+CONTAINER_CLI=podman make container
+
+# Push to a specific registry
+REGISTRY=docker.io/myorg make container
+```
+
+#### Legacy Single-architecture Container
+
+For backward compatibility, you can still build a single-architecture container:
+
+```bash
+make binary-image
+```
+
+### Deployment
+
+To build, push, and deploy:
+
+```bash
+# Multi-architecture deployment
+make deploy
+
+# Legacy single-architecture deployment
+make deploy-legacy
+```
+
+## Dockerfile
+
+The new build system uses `build/package/Dockerfile.multi`, which:
+
+1. Uses a multi-stage build process
+2. Supports multiple architectures via the `TARGETARCH` build argument
+3. Uses the latest Alpine base image for security
+4. Uses Go's native embed package instead of third-party libraries

+git diff# GitWebhookProxy Helm Chart
+
+This Helm chart deploys GitWebhookProxy on Kubernetes with support for GCP-specific features.
+
+## GCP Features
+
+The chart now supports the following GCP-specific features:
+
+### FrontendConfig
+
+Enable and configure a GCP FrontendConfig resource:
+
+```yaml
+gitWebhookProxy:
+  ingress:
+    gcp:
+      enabled: true
+      name: "my-frontend-config"  # Optional custom name
+      sslPolicy:
+        enabled: true
+        name: "modern-ssl-policy"
+      redirects:
+        enabled: true
+        type: PERMANENT_REDIRECT
+        responseCode: MOVED_PERMANENTLY_DEFAULT
+```
+
+### BackendConfig
+
+Configure a named backend with health checks:
+
+```yaml
+gitWebhookProxy:
+  ingress:
+    gcp:
+      backend:
+        enabled: true
+        name: "my-backend-config"  # Optional custom name
+        healthCheck:
+          enabled: true
+          checkIntervalSec: 30
+          timeoutSec: 5
+          healthyThreshold: 2
+          unhealthyThreshold: 3
+          type: HTTP
+          port: 8080
+          requestPath: "/health"
