A growing family of solutions and an active and enthusiastic contributing community is helping position Mono to become the leading choice for development of cross platform applications.
How to use this image
This image will run stand-alone Mono console apps.
Dockerfile in your Mono app project
This example Dockerfile will run an executable called
FROM mono:3.10-onbuild CMD [ "mono", "./TestingConsoleApp.exe" ]
Place this file in the root of your app, next to the
.sln solution file. Modify the exectuable name to match what you want to run.
This image includes
ONBUILD triggers that adds your app source code to
/usr/src/app/source, restores NuGet packages and compiles the app, placing the output in
With the Dockerfile in place, you can build and run a Docker image with your app:
$ docker build -t my-app . $ docker run my-app
You should see any output from your app now.
This Docker image is provided by Xamarin, for users of the Mono Project.
Thanks to Michael Friis for his preliminary work.
mono images come in many flavors, each designed for a specific use case.
This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.
This image does not contain the common packages contained in the default tag and only contains the minimal packages needed to run
mono. Unless you are working in an environment where only the
mono image will be deployed and you have space constraints, we highly recommend using the default image of this repository.
