Containers, your way

Maintained and compliant
Support for any open source software
On any Kubernetes

Familiar for developers,
as dependable as Ubuntu

Rely on Ubuntu's demonstrated track record for containers that are:

Supported. Timely updates and patches, building on Ubuntu's security track record.
Stable. Long-term support with a consistent, predictable lifecycle and support commitment.
Seamless. Developer-friendly, smooth experience from development to production.
Small. Ultra-small, resource-efficient, yet robust images with chiseled (distroless) Ubuntu.

Critical CVE fixes in 24 hours

Scanning container images for vulnerabilities is now widespread, but fixing them requires dedicated skills and infrastructure. Trusted provenance is key.

Canonical's OCI images provide ready-to-use images, free of high and critical CVEs. Images are built on the same trusted infrastructure in Ubuntu, and updated automatically when apps or dependencies are fixed.

Our container portfolio

Build on a solid foundation

Use the stability and security of Ubuntu as the foundation for your containers. Ubuntu-base images provide a robust and trusted starting point for building and deploying your containers, ensuring compatibility, performance, and long-term support. Experience Ubuntu's consistent performance across cloud, desktop, and server – and bring that same reliability to your containers. What’s more, FIPS-enabled containers can be deployed by using Ubuntu Pro, Canonical’s comprehensive subscription for open source security, support, and compliance.

Canonical's container toolkit

Rockcraft and Chisel provide the tools and flexibility to build Ubuntu-based containers that perfectly align with your application's requirements. Canonical's variation of “distroless” containers, called chiseled Ubuntu containers, take size optimization to a new level.

Developers can keep building with Ubuntu and rely on ultra-small, bitwise identical images tailored for production.

No more worries about library incompatibilities, just seamless development to deployment.

What industry experts say

“There has always been a need for smaller and tighter images. Developers remind us, as a base image provider, of that on a regular basis. Chiseled images leapfrog over approaches we've looked at in the past. We love the idea and implementation of chiseled images and Canonical as a partner. When technical leaders at Canonical shared the first demos of chiseled images with us, we immediately wanted to be a launch partner, and we're thrilled that we're shipping Ubuntu chiseled images for .NET as part of the GA release.”
