Docker Mono .NET Demo
Example self-hosted Nancy API running on Mono, in a minimal Docker image (< 20mb)
Uses a local Vagrant Debian Wheezy box to build the linux artifact for embedding as a static binary in the Docker container.
Getting Started
Note: You will need Vagrant and Virtualbox for this, or otherwise a working local Mono distribution on a Linux host.
vagrant up
vagrant ssh
cd /vagrant && ./build.sh
logout
docker build -t mfellows/mono-api .
docker run -d -p 8888:8888 mfellows/mono-api
You can now hit your API on port 8888 (you may need to wait a minute for it to spin up: run docker logs <container id> and look for "started"):
And there it is - a .NET API running in a ~20mb Docker container!
curl $(boot2docker ip):8888
Hello World
Performance
As an interesting side note, it still performs quite well with no tuning. My host Mac OSX the running Virtualbox process sits around 5% CPU usage during this basic stress test.
ab -c 100 -n 10000 "$(boot2docker ip):8888/"
Output:
mfellows@matt.mit ~/development/public/mono-api/console $ ab -c 100 -n 10000 "$(boot2docker ip):8888/"
