docker-openvswitch

This repository contains a Dockerfile that builds the latest Open vSwitch from source, with DPDK support enabled. It focuses on a few specific things:

• Isolated build stages that minimize final image size
• Isolated network access during build stages to improve reproducibility and security
• Downstream patches to improve performance and stability

This image is primarily built to be consumed by Atmosphere, however it may be useful for other projects as well.

Release helper

The release workflow creates or refreshes a GitHub draft release from the pinned Open vSwitch commit and the local quilt patch stack whenever changes merge to main. The draft can then be promoted in GitHub once reviewed.

The helper describes OVS_COMMIT against the upstream Open vSwitch tags and adds the number of patches listed in patches/series. For example, an OVS_COMMIT described as v3.3.9-4-g... with two local patches becomes v3.3.9-6.

Run the built-in tests with:

uv run hack/release.py --self-test

To create or refresh the GitHub draft release locally:

GITHUB_REPOSITORY=vexxhost/docker-openvswitch uv run hack/release.py

The release path uses GITHUB_TOKEN or GH_TOKEN for authentication. The Open vSwitch source must be checked out at ./ovs, which the release workflow does automatically.
