About
This image contains the .NET Monitor Base installation.
Use this image as a base image for building a .NET Monitor image with extensions.
Watch discussions for Docker-related .NET announcements.
New: Ubuntu Chiseled Images
Ubuntu Chiseled .NET images are a type of "distroless" container image that contain only the minimal set of packages .NET needs, with everything else removed. These images offer dramatically smaller deployment sizes and attack surface by including only the minimal set of packages required to run .NET applications.
Please see the Ubuntu Chiseled + .NET documentation page for more info.
Usage
The .NET Docker samples show various ways to use .NET and Docker together. See Building Docker Images for .NET Applications to learn more.
Building a Custom .NET Monitor Image
The following Dockerfiles demonstrate how you can use this base image to build a .NET Monitor image with a custom set of extensions.

Support
Lifecycle
Image Update Policy
- We update supported .NET images within 12 hours of any updates to their base images (e.g. debian:bookworm-slim, windows/nanoserver:ltsc2022, etc.).
- We re-build all .NET images as part of releasing new versions of .NET including new major/minor versions and servicing.
- Distroless images such as Ubuntu Chiseled have no base image, and as such will only be updated with .NET releases and CVE fixes as described below.
CVE Update Policy
.NET container images are regularly monitored for the presence of CVEs. A given image will be rebuilt to pick up fixes for a CVE when:
- We detect the image contains a CVE with a CVSS score of "Critical"
- AND the CVE is in a package that is added in our Dockerfile layers (meaning the CVE is in a package we explicitly install or any transitive dependencies of those packages)
- AND there is a CVE fix for the package available in the affected base image's package repository.
Please refer to the Security Policy and Container Vulnerability Workflow for more detail about what to do when a CVE is encountered in a .NET image.
