This repo contains plugins meant for testing/development of latest windows features. Their primary use case right now is with a CRI and containerd

• sdnoverlay
• nat
• sdnbridge

Releases are fully automated via GitHub Actions. To create a new release:

1. Ensure all changes are committed and tests pass:

   make test

2. Update CHANGELOG.md with the new version and changes

3. Create a GPG-signed annotated tag:

   git tag -s v0.x.x -m "Release v0.x.x
   
   Brief description of changes.
   See CHANGELOG.md for full details."

   Important: Always use GPG-signed tags (-s flag) for releases. This ensures authenticity and prevents tampering.

4. Push the tag:

   git push origin v0.x.x

5. Monitor the release: The GitHub Actions workflow will automatically:

   • Build binaries for all platforms
   • Run CI tests
   • Generate SHA256/SHA512 checksums
   • Create and publish the GitHub release

Each release includes:

• windows-container-networking-cni-amd64-v0.x.x.zip - Binary package
• windows-container-networking-cni-amd64-v0.x.x.zip.sha256 - SHA256 checksum
• windows-container-networking-cni-amd64-v0.x.x.zip.sha512 - SHA512 checksum

• Never modify published releases - If there's an issue, create a new patch version
• Always use GPG-signed tags - Ensures release authenticity
• Verify checksums - All artifacts include cryptographic checksums
• Tag format - Always use vMAJOR.MINOR.PATCH format (e.g., v0.3.2)

See CHANGELOG.md for release history.

These plugins are made for windows and need to be compiled for windows. However, you can cross-compile them from Linux.

If you have make installed on your system:

make all - will build all plugins: nat.exe, sdnbridge.exe, and sdnoverlay.exe make <plugin> - will build an individual plugin

Else:

GOOS=windows GOARCH=amd64 go build -v -o out/<plugin>.exe plugins/<plugin>/*.go

On a Linux machine, run make dev, then make all. That will cross-build the Windows binaries in a clean environment.

There is a test suite that should be run (make test) before any changes. Opening a PR should trigger a Jenkins run that will run all the tests. If you wish to run them locally, you'll need a nanoserver image pulled from docker.

Currently there are two groups of end-to-end tests shared by all the plugins

• Properties Verification - tests an add command and verifies that the resulting state is as expected. I.e. we attach an endpoint that endpoint has policy x,y,z etc.
• Connectivity Testing - creates a container and makes a CNI call for it and verifies that the container has connectivity for pod-to-pod, host-to-pod, pod-to-host, and pod-to-internet
