ASP.NET Core Runtime

Important: The images from the dotnet/nightly repositories include last-known-good (LKG) builds for the next release of .NET.

See dotnet for images with official releases of .NET.

About

This image contains the ASP.NET Core and .NET runtimes and libraries and is optimized for running ASP.NET Core apps in production.

Watch discussions for Docker-related .NET announcements.

Usage

The .NET Docker samples show various ways to use .NET and Docker together. See Introduction to .NET and Docker and Host ASP.NET Core in Docker containers to learn more.

Container sample: Run a web application

You can quickly run a container with a pre-built .NET Docker image, based on the ASP.NET Core sample.

Type the following command to run a sample web application:

docker run -it --rm -p 8000:8080 --name aspnetcore_sample mcr.microsoft.com/dotnet/samples:aspnetapp

After the application starts, navigate to http://localhost:8000 in your web browser. You can also view the ASP.NET Core site running in the container from another machine with a local IP address such as http://192.168.1.18:8000.

Note: ASP.NET Core apps (in official images) listen to port 8080 by default, starting with .NET 8. The -p argument in these examples maps host port 8000 to container port 8080 (host:container mapping). The container will not be accessible without this mapping. ASP.NET Core can be configured to listen on a different or additional port.

See Hosting ASP.NET Core Images with Docker over HTTPS to use HTTPS with this image.

Image Variants

.NET container images have several variants that offer different combinations of flexibility and deployment size. The Image Variants documentation contains a summary of the image variants and their use-cases.

Distroless images

.NET distroless container images contain only the minimal set of packages .NET needs, with everything else removed. Due to their limited set of packages, distroless containers have a minimized security attack surface, smaller deployment sizes, and faster start-up time compared to their non-distroless counterparts. They contain the following features:

Minimal set of packages required for .NET applications
Non-root user by default
No package manager
No shell

.NET offers distroless images for Azure Linux and Ubuntu (Chiseled).

ASP.NET Core Composite Images

Starting from .NET 8, ASP.NET Core Composite images are optimized for performance using ReadyToRun (R2R) compilation. For more information, see the composite images section in the Image Variants documentation.

Image Update Policy

Base Image Updates: Images are re-built within 12 hours of any updates to their base images (e.g. debian:bookworm-slim, windows/nanoserver:ltsc2022, etc.).
.NET Releases: Images are re-built as part of releasing new .NET versions. This includes new major versions, minor versions, and servicing releases.
Critical CVEs: Images are re-built to pick up critical CVE fixes as described by the CVE Update Policy below.
Monthly Re-builds: Images are re-built monthly, typically on the second Tuesday of the month, in order to pick up lower-severity CVE fixes.
Out-Of-Band Updates: Images can sometimes be re-built when out-of-band updates are necessary to address critical issues. If this happens, new fixed version tags will be updated according to the Fixed version tags documentation.

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.
