Run the .NET Core SDK and Runtime from a Docker container

Overview

I run a lot of my tooling straight from Docker containers instead of installing them on my system.
Doing so helps me ensure I'm using the desired version(s) straight from the official maintainers, helps me keep my system tidy, and guarantees a consistent environment across machines.

I've started getting my feet wet with .NET Core in preparation for an upcoming project and noticed that neither Microsoft's documentation nor their Docker Hub page for .NET Core mention running the SDK or runtimes straight from the published images, so I've put together a simple wrapper to run the .NET Core SDK and Runtime from a Docker container:

https://github.com/bshaw/dotnet-docker/.

The script uses the official Microsoft .NET Core SDK image using the 3.1 tag (Debian 10).
It is based on (effectively forked from) the Docker Compose Run docker-compose in a container script, which properly handles volume mappings and various options based on the environment.

Installation

Place the wrapper script in your path and made it executable:

sudo curl -L --fail https://raw.githubusercontent.com/bshaw/dotnet-docker/master/run.sh -o /usr/local/bin/dotnet
sudo chmod +x /usr/local/bin/dotnet

Usage

Use the dotnet command as you would if it were installed locally:

❯ dotnet --info

TODO: Multi version support

The dotnet version is specified as a variable in the script - you can easily update the file on your system depending on your requirements.
I may also update the script to support multiple versions.
