Canonical partners with Snyk for scanning chiseled Ubuntu containers

Canonical, the publisher of Ubuntu, is pleased to announce a new partnership with developer-focused cybersecurity company Snyk. Snyk Container, Snyk's container security solution, now offers native support for scanning chiseled Ubuntu containers. This partnership will create a path to a more secure container ecosystem, where developers will no longer need to compromise on scanning accuracy for their minimal images.

Distro-aware, without the distro

Chiseled Ubuntu images include a manifest, and when Snyk Container's engine parses chiseled Ubuntu slices, it can correctly identify the corresponding Ubuntu components. With a direct pipeline to Canonical's security team, you can rest assured that Snyk's scan results of a chiseled Ubuntu image reflect the latest vulnerability information.

Support for chiseled Ubuntu images is implemented seamlessly into Snyk Container, so developers can use the same commands to scan chiseled Ubuntu images as they would for any other image. Snyk does the work behind the scenes to identify the chiseled slices, without requiring separate commands or scanning workflows.

"Snyk now automatically recognizes chiseled Ubuntu slices, giving developers the precise vulnerability data they need to ship fast and stay secure, without any extra configuration or overhead," said Pratip Banerji, Product Manager at Snyk.

Bridging the distroless security gap

Standard container images, whilst great for development, have clear drawbacks when it comes to production. The inclusion of a full OS, shell, package manager, and utilities results in chunky containers and a wide attack surface, meaning higher network costs and an increased likelihood of vulnerabilities.

Distroless images contain only the application and its runtime dependencies, making them much smaller and, in theory, more secure. But at what cost?

The typical approach to building distroless images is top-down, inflating the base image and cherry-picking to trim it down. The complex builds, specialized tooling, and deep distro knowledge required to build a distroless image with full accuracy mean that package metadata, crucial for precise security scanning, is often omitted, leading to inaccurate CVE reporting.

To solve the challenges of the distroless security gap, Canonical created chiseled Ubuntu  containers.

Unlike typical distroless images, chiseled Ubuntu images are managed bottom-up using Chisel, a novel package manager that slices packages to create compact, secure software. Built using packages available in the Ubuntu archives, chiseled Ubuntu images are minimal in size, but retain the metadata needed for accurate security scans.

Get production-ready, securely-maintained container images

With Snyk and chiseled Ubuntu images, developers now have the ultimate toolset for production-ready security. Snyk's native support for scanning chiseled Ubuntu images means greater precision, reduced noise, and a faster CI/CD.

"Chiseled Ubuntu containers are ultra-small and secure-by-design, shipping without a shell, root user, or package manager by default," said Mark Lewis, VP of Application Services at Canonical. "The advent of distroless images has led to scanners struggling to detect software components and thus vulnerabilities; Canonical's new partnership with Snyk means a more complete audit of production containers. Our mutual customers and community can have confidence in a complete and comprehensive approach to container security."

When Snyk Container scans chiseled Ubuntu images, the slices are correctly identified, reducing the risk of false negative results that is prevalent with typical distroless images. This heightened visibility into the software supply chain means that Snyk can accurately report and remediate CVEs for chiseled Ubuntu images. The minimal size of these images also results in less vulnerability bloat, and faster scanning compared to standard container images. While chiseled images harden the foundation, Snyk provides visibility into the application layer, securing everything running on top, including application code, open-source dependencies, and configurations.

Introducing MicroCloud Cluster Manager

Your single entry point to all your MicroClouds

Today, we're excited to introduce the beta release of MicroCloud Cluster Manager , a new way to discover, organize, and operate your MicroCloud environments from a single, unified interface.

MicroCloud  is an open source cloud platform that makes it simple to create lightweight, resilient clusters anywhere. As teams scale from one cluster to many, visibility and coordination quickly become essential. Cluster Manager is built to solve exactly that.

One dashboard. Every MicroCloud.

MicroCloud Cluster Manager serves as the central entry point for all your MicroClouds.Whether you're managing your data center, a few edge clusters, or dozens across environments, Cluster Manager gives you:

• Unified visibility across all enrolled MicroCloud clusters
• Streamlined access to key cluster details and metrics
• A foundation for operational oversight, ready to grow with your needs

With just a few clicks, you can enroll your first cluster and immediately begin exploring its health, resources, and configuration.

A screenshot of the MicroCloud Cluster Manager dashboard
Why Cluster Manager?

As MicroCloud deployments grow, teams often face common challenges:

• Where is each cluster running?
• How do I get a quick overview of cluster health?
• How do I streamline access as more environments come online?

Cluster Manager tackles these problems by giving you a single, consistent point of control, no matter how many clusters you operate or where they are deployed.

Built to extend: monitoring, alerting, and more

Cluster Manager is designed as a flexible platform. Out of the box, it makes cluster discovery and access effortless, but it also lays the groundwork for the more advanced operational tooling teams rely on.

MicroCloud Cluster Manager is designed to be fully extensible with the Canonical observability stack , giving you a complete Grafana dashboard for every cluster out of the box. With no additional setup required. The beta release is currently extensible only with the LXD Grafana dashboard, giving you observability for your virtualization layer. We are working on expanding this to also include MicroCeph and MicroOVN observability. 

A screenshot of the LXD Grafana dashboard
Enroll your first cluster

Getting started is simple:

• Deploy your MicroCloud cluster
• Connect it to Cluster Manager
• Explore your unified dashboard

From there, you can continue enrolling additional clusters and begin shaping your own multi-cluster view tailored to your infrastructure.

A screenshot of the MicroCloud Cluster Manager dashboard
Built on Open Source: Juju, Postgres, and Traefik

MicroCloud Cluster Manager  is built entirely on open source technology, just like MicroCloud  itself. It's orchestrated with Juju , using the PostgreSQL  and the Traefik Ingress Operator  charms to provide a solid, production-ready foundation. This stack ensures that day-two operations are solved out of the box, from automated updates to scaling and resilience.

With a fully open source architecture, every part of the platform, storage, ingress, orchestration, and the Cluster Manager application, is transparent, reliable, and built to grow with your infrastructure.

The beginning of a bigger ecosystem

MicroCloud Cluster Manager is our first step toward a richer, more powerful management experience for MicroCloud users. Over time, it will become a full operational console for cluster insights, automation, and lifecycle management.

We're excited to share this preview and look forward to your feedback as we continue to expand its capabilities.

Follow the how-to outlined in our documentation  to try it.
