Chainguard Container for openvswitch-vswitchd-kolla

Open vSwitch (ovs-vswitchd + ovsdb-server) packaged for use as drop-in replacements for the upstream openstack-kolla container images

Chainguard Containers are regularly-updated, secure-by-default container images.

openvswitch-kolla

Minimal, distroless Open vSwitch images compatible with the upstream openstack.kolla/openvswitch image set.

This is an image group. The published variants mirror the upstream kolla image layout one-to-one:

The two daemons are a runtime pair: ovs-vswitchd connects to ovsdb-server over /run/openvswitch/db.sock and registers as the Open_vSwitch table primary. They are typically deployed together.

The images share the kolla startup contract: /usr/local/bin/kolla_start reads /var/lib/kolla/config_files/config.json, runs kolla_set_configs, then dispatches to the configured command. They are drop-in replacements for the upstream kolla/openvswitch-vswitchd / kolla/openvswitch-db-server images when consumed by kolla-ansible or kayobe — including under the OVN mechanism driver, where ovn-controller programs the same local Open vSwitch.

OpenStack release streams

The image stream tracks the OpenStack release cycle (e.g. 2026.1 Gazpacho). Each stream corresponds to the openstack-kolla-scripts-<stream> apk package group and pins to the Open vSwitch minor that the matching Ubuntu Cloud Archive ships for that release (3.7 for 2026.1, 3.6 for 2025.2, 3.5 for 2025.1).

Each published image carries its release-id (2026.1, 2025.2, 2025.1), kolla-scripts version tags (e.g. 22.0.0, 22.0, 22), and the corresponding Open vSwitch version tags (e.g. 3.7.1, 3.7, 3); latest tracks the most recent maintained stream.

Configuration

Configuration is supplied via kolla's config.json mechanism — see the upstream kolla-ansible openvswitch role for the canonical examples. Refer to the upstream Open vSwitch documentation for the full set of options.

What are Chainguard Containers?

Chainguard's free tier of Starter container images are built with Wolfi, our minimal Linux undistro.

All other Chainguard Containers are built with Chainguard OS, Chainguard's minimal Linux operating system designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a development, or -dev, variant.

In all other cases, including Chainguard Containers tagged as :latest or with a specific version number, the container images include only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager.

Although the -dev container image variants have similar security features as their more minimal versions, they include additional software that is typically not necessary in production environments. We recommend using multi-stage builds to copy artifacts from the -dev variant into a more minimal production image.

Need additional packages?

To improve security, Chainguard Containers include only essential dependencies. Need more packages? Chainguard customers can use Custom Assembly to add packages, either through the Console, chainctl, or API.

To use Custom Assembly in the Chainguard Console: navigate to the image you'd like to customize in your Organization's list of images, and click on the Customize image button at the top of the page.
