+# Protobuf Generation Docker Environment
+
+This Docker environment contains the tools and environment required to generate function-mesh protobuf Go definitions.
+
+## Requirements
+
+- protoc: v3.17.3
+- protoc-gen-go: v1.25.0
+- protoc-gen-go-grpc: v1.0.0
+- Go: 1.24.4+
+
+**Note**: This image uses a Debian base (not Alpine) to ensure compatibility with the protoc x86_64 binary, which is compiled for glibc rather than musl libc.
+
+## Build and Usage
+
+### 1. Build Docker Image
+
+```bash
+docker build -f Dockerfile.protogen -t function-mesh-protogen .
+```
+
+### 2. Run Protobuf Generation
+
+```bash
+# Run container and generate protobuf files
+docker run --rm -v $(pwd):/workspace function-mesh-protogen
+
+# Or run interactively for debugging
+docker run --rm -it -v $(pwd):/workspace function-mesh-protogen bash
+```
+
+### 3. Manual Script Execution
+
+If you need manual control over the generation process:
+
+```bash
+# Enter container
+docker run --rm -it -v $(pwd):/workspace function-mesh-protogen bash
+
+# Execute manually inside container
+cd /workspace
+./controllers/proto/generate.sh /workspace
+```
+
+## Generated Files
+
+The script will update the following files:
+- `controllers/proto/Function.pb.go`
+
+## Environment Verification
+
+You can verify tool versions inside the container:
+
+```bash
+protoc --version              # Should show libprotoc 3.17.3
+go version                   # Should show go1.24.4+
+```
+
+## Troubleshooting
+
+If you encounter permission issues, ensure the generate.sh script has execute permissions:
+
+```bash
+chmod +x controllers/proto/generate.sh
+```
+
+If you encounter protoc-gen-go not found issues, ensure $GOPATH/bin is in PATH:
+
+```bash
+export PATH=$PATH:$(go env GOPATH)/bin
+```
