# Creating a new docker image for use in an official build

Our official build in VS Online builds coreclr in a docker container. The images for this are stored on Chris Costa's docker hub account: https://hub.docker.com/r/chcosta/dotnetcore/. When adding support for a new distro, you need to create a docker image with the appropriate prerequisites for use in building the coreclr repository.

Notes when making a new image:

Run the build steps that the official build uses to ensure that the image will work as expected. https://devdiv.visualstudio.com/DevDiv/_build/index?context=allDefinitions&path=%5C&definitionId=1713&_a=completed

Running dotnet commands will add a ton of binary data to your home directory. Delete the ~/.nuget directory to avoid bloating the size of the docker image.
